What is a Standard Bath Size? Bath Dimensions and How to Know Which Size Bath to Buy
Standard bath size
If you are currently bath shopping but are unsure on which size bath to get, you have landed in the right place.
In this guide, we'll explain the standard bath sizes, delve into smaller and larger options, straight and corner bath dimensions, as well as freestanding baths. You’ll not only discover which bath size you need for your bathroom but which style of bath might suit. We’ve also added a list of ways that you can figure out the perfect bath size for your bathroom.
What size is a standard bath?
Standard bath sizes are common dimensions that fit comfortably in most bathrooms. However, these sizes can vary slightly from country to country, so it's crucial to consider your bathroom's available space when selecting a bath size for your bath.
In the UK, the standard bath size can vary, but there are typical dimensions that are commonly used for standard rectangular baths. A standard bath in the UK often measures around 1700mm (170cm) in length, 700mm (70cm) in width, and has a depth of about 400mm (40cm). These dimensions are approximate and can vary depending on the specific design and manufacturer.
At 34 St John we sell baths that range from 1500 to 1800 mm in length, 700mm to 900mm in width and 500 to 690mm in height.
Small Bath Size
Smaller baths are a practical choice for bathrooms with limited space. The size of a small bath can start from 130cm (1300mm) in length. But the average bath size for a small bath is around 1500mm-1600mm in length, 700m (70 cm) in width, and 360mm (36 cm) in depth. In most cases the width of a small bath does not deviate from the standard 700mm (70cm). A smaller size tub is excellent for small bathrooms or en-suites, where space is limited.
Large Bath Sizes UK
For those with much larger bathrooms, there are more options available when it comes to the sizing of large baths.The dimensions of large baths can vary, but a common size for a large rectangular bath in the UK is approximately:
Length: 1700mm to 1800mm (170 cm to 180cm)
Width: 800mm to 900mm (80cm to 90cm)
Depth: 450mm to 550mm (45cm to 55cm)
These dimensions can offer more room for relaxation and comfort compared to standard-sized baths. Larger double ended bath tubs can also comfortably accommodate two people at the same, making them an excellent choice if that's your preference.
It's essential to keep in mind that the specific size of large baths can vary based on the design, style, and manufacturer. When selecting a large bath, consider the available space in your bathroom to ensure a proper fit.
Straight Bath Size
Straight baths are the most common type, with a classic rectangular shape. They come in various lengths, typically ranging from 1500mm to 1800mm (152 to 183 cm) and widths between 700mm to 900mm (71 to 91 cm). The depth varies between 360mm and 560mm (36 to 56 cm), offering different water capacities and comfort levels.
Corner Bath Size
As the name suggests, corner baths are designed to fit snugly into the corner of your bathroom. They can be an excellent space-saving solution and are a great option if you have a small or oddly shaped bathroom. Corner baths typically measure around 1200mm to 1500mm (120 to 150 cm) along each side. Their depth is usually around 450mm-500mm (40cm-50cm).
The most common corner bathtub dimensions are 4ft x 4 ft (120cm) and 5 ft x 5 ft (150cm). Many corner bathtubs can comfortably fit more than one bather, so are a great option if that is what you are looking for.
Triangular Corner Bath Size
Some corner baths have a unique triangular shape, which can be a stylish and space-efficient option. They typically measure around 1500mm (150 cm) along two sides, with a depth of 500mm (50 cm) at the centre.
Freestanding Bath Size
Freestanding baths are the ultimate focal point for a modern-style bathroom. The length and width of freestanding baths can vary widely, with lengths ranging from 1400mm to 1800mm (140 to 180 cm) and widths from 700mm to 1000mm (70 to 100 cm). Depths generally range from 400-600mm (40 to 60 cm).
It’s worth noting that some freestanding baths come with claw feet - so you’ll have to make space for those. 34 St John baths stay true to our modern, minimalist aesthetic and have a beautifully smooth finish.
It is also important to know that freestanding stone baths are notoriously heavy (some are over 100kg), so make sure your bathroom floor can handle the weight beforehand.
How to know which size bath you’ll need for your bathroom
- Determine the Ideal Bath Location: Based on your bathroom layout, decide where the bath would be best situated. Common bath locations include along a wall, in a corner, or alongside a window. Consider your preferences and available space.
- Select a Bath Type: Choose the type of bath you prefer, whether it's a standard rectangular bath, a corner bath, a freestanding bath, or a specialty shape like a triangular bath. Different types have varying dimensions, so select one that suits your bathroom layout and aesthetic preferences.
- Check Bath Dimensions: Research the dimensions of the bath you're interested in. Check the length, width, and depth. Pay attention to the bath's exterior and interior dimensions, as well as its water capacity. Ensure that the bath's dimensions align with your bathroom's available space and layout.
- Create a Floor Plan: Sketch a floor plan of your bathroom, including the proposed bath location and dimensions. This visual representation will help you visualise how the bath fits within the space and how it relates to other fixtures and features.
- Consider User Comfort: Think about the comfort of bath users. Ensure there is enough leg room and space to bath comfortably. Also, consider the depth of the bath to ensure it provides the desired soaking depth.
- Check Clearances: Verify that there are sufficient clearances around the bath, especially if you plan to install a shower or other fixtures nearby. Maintain a safe and functional distance from walls, doors, and other fixtures.
- Consult with Professionals: If you're unsure about the right bath size or how it will fit into your bathroom, consult with a bathroom designer or contractor. They can provide guidance based on their expertise and experience.
- Visualise the Final Look: Visualise the bath in your bathroom space, taking into account the aesthetic and practical aspects. Consider how it complements the overall design and style of the bathroom.

How to Pull Off an Open Plan Bedroom Bathroom Design
Imagine a space where morning light spills across Italian marble floors, sweeping from your silk-draped bed to your freestanding stone bath. An open plan bedroom bathroom revolutionises the way we think about personal space, offering a fresh approach to modern living. This guide will take you through the essential elements of creating a successful open plan design, from practical considerations to luxury finishes. Whether you're renovating or building from scratch, you'll discover how to craft a space that perfectly maintains the privacy and comfort you need. Making Space Work Smarter The secret to an exceptional open plan layout lies in how you'll actually live in it. Map out your morning routine, from the first stretch in bed to your final glance in the mirror. Position your vanity unit where natural light hits your face, not your back. Consider placing your shower or tub where you can glimpse the morning sky. A partial wall at 4-5 feet height can house plumbing while doubling as a backdrop for your bed. https://pin.it/76sQe36Xr Choosing Materials That Last Skip the standard bathroom tiles. Instead, experiment with continuous surfaces that can handle both wet and dry areas. Polished concrete flows beautifully from bedroom to bathroom, developing a rich patina over time. For walls, marine-grade teak brings warmth while withstanding moisture. If marble catches your eye, book-matched slabs create dramatic impact, consider carrying a single piece up the wall and across the floor. Every material you choose will be on constant display, so invest in quality that can handle daily exposure to moisture. https://pin.it/7DVvJ88PH Making Privacy Work Make sure to address the elephant in the room - privacy. Consider installing electrochromic glass panels that switch from clear to opaque. Or take inspiration from Japanese architecture with sliding wooden screens that double as art pieces. Think of privacy elements as art installations that enhance rather than divide your space. https://pin.it/1RI2V8e43 Mastering the Light Your lighting should tell a story throughout the day, starting with discreet LED strips tucked beneath floating vanities and along floor transitions to guide your midnight wanderings with a gentle glow. By your bed, mount reading lights that pivot smoothly to wash your bathroom space in warmth when desired. Let nature play its part by carving out a skylight above your shower, where sunlight paints shifting patterns across marble and glass. https://pin.it/NeM0pHYdf Controlling Climate and Comfort The most important aspect of open plan bathrooms is perfecting the climate control. Install a multi-speed ventilation system with separate fans for shower and toilet areas. Underfloor heating should extend throughout the entire space, with separate zones for wet and dry areas. Position air vents strategically to prevent steam from condensing on your bedroom mirrors and to keep your bedding fresh. Adding a heated towel rack will also help manage moisture while keeping linens fresh and ready for use. https://pin.it/4eqSukEUE Smart Storage Solutions Your space should work like a well-designed yacht where every inch serves a purpose. Create a shower niche visible from your bed with enough depth to showcase art pieces when not storing toiletries. Place a rotating closet system within arm's reach of your shower, ensuring tomorrow's outfit is always perfectly positioned for your morning routine. The artistry lies in concealing these storage solutions so thoroughly that they vanish into your design. Getting the Details Right Success lies in the details that bridge both spaces. Install a surround-sound speaker system with waterproof bathroom speakers that sync perfectly with your bedroom audio, letting your music flow seamlessly as you move between spaces. Select unified fixtures and accessories in brass throughout, from your shower head to your bedside lamps. Try to hide charging stations inside vanity drawers where your devices can power up while staying protected from bathroom steam. Position a beverage station where it's reachable from both your bed and bath, perfect for morning coffee while you run the shower or evening tea as you wind down. These thoughtful connections between bedroom and bathroom spaces transform two rooms into one luxurious retreat where every detail feels considered. https://pin.it/6GEAhra34 -
How to Create a Boutique Hotel Style Bathroom
That moment when you swing open a hotel bathroom door and your breath catches, it's not just clever marketing at work. Forget the myth that you need massive square footage, what matters most is the strategic choices that transform your daily routine into a retreat experience. Whether you're planning a full renovation or looking to upgrade your existing space, we want to show you how to create a hotel style bathroom that makes you feel like you're on vacation every single day. https://pin.it/4zwJ9TLQP Take Inspiration from Hotel Styles The world's most memorable boutique hotels each tell a unique design story. Consider the minimalist theme of Copenhagen's hotels, where fluted wooden vanities meet curved mirrors and matte black fixtures. Or step into a Parisian bathroom where bold marble contrasts with industrial black metalwork and vintage-inspired lighting. For a more relaxed vibe, look to Australia's coastal hotels, where bleached wood meets textured limestone and oversized windows blur the line between indoors and out. https://pin.it/5naKT5V8x Choose a Relaxing Colour Palette Colour sets the mood for your daily rituals. The most spa-like hotel bathrooms start with a powerful base; think crisp whites with subtle grey veining, creamy stone that catches morning light, or charcoal that grounds the space. Layer in contrast through fixtures and finishes, matte black taps against white tiles create visual anchors, while brushed brass brings warmth to cool greys. The trick lies in restraint, limit yourself to three finishes and let natural materials add subtle variations. https://pin.it/3kboxkJ8l Add Fluted Furniture for Texture Transform flat surfaces into visual stories with fluted details, a design tactic borrowed from the world's leading hotels. A fluted wooden vanity turns a basic storage piece into a sculptural element. Modern boutique hotels often use this architectural detail in unexpected ways, think curved fluted tiles wrapping around a shower enclosure, or a reeded glass partition that separates the vanity from the toilet. https://pin.it/VImnFOOlb Focus on Comfortable Lighting Light makes or breaks a bathroom's atmosphere, it's why hotel bathrooms always seem to make you look better. The secret lies in strategic layering; mount sconces at eye level to eliminate unflattering shadows, install dimmable downlights for tasks, and add a backlit mirror that creates that coveted soft glow around your reflection. Install dimmers on every circuit, including the shower light, and watch your bathroom transform into a personal sanctuary. No single light source should do all the work, it's the interplay between layers that creates that perfect boutique hotel ambiance. https://pin.it/1Qynhg4Zm Choose High-Quality Materials The magic of hotel bathrooms isn't just what you see, it's what you touch. Focus your design plans on the daily contact points, taps that feel perfectly weighted, shower controls that turn with precision, drawers that glide shut silently. Choose large-format porcelain tiles that give you premium looks with practical benefits, better durability, easier cleaning, and none of the maintenance headaches. When it comes to brassware, invest in finishes that get better with age. Quality shows in the details, the smooth edges of a vanity top, the solid feel of a shower screen, the precise alignment of tile work. https://pin.it/1P47NeaDO Include a Freestanding Bath or Walk-In Shower The heart of every standout hotel bathroom is either a statement shower or bath that makes you want to linger. A freestanding tub, thoughtfully positioned to catch natural light, transforms your evenings into a moment of escape. If you have a smaller bathroom, consider a walk-in shower with floor-to-ceiling glass creates that same sense of luxury while making your bathroom feel larger than it is. https://pin.it/HDY4atFVp Layer Soft Textiles Invest in properly weighted towels that get softer with each wash, and buy extras so you can rotate them like hotels do. A deeply cushioned bath mat in pure cotton or bamboo makes that first step out of the shower feel indulgent. Skip the budget bathrobes and find one that's worthy of keeping on display, think waffle-weave cotton or soft linen that looks better and slightly rumpled. Keep your palette tonal with warm whites, soft greys, or deep charcoals to create that considered look. Then master the art of display, roll your hand towels instead of folding them, stack your bath sheets with precision, and keep your robe draped. https://pin.it/4Theqqge8 Keep Storage Simple and Tidy Start with a vanity unit that works hard, think deep drawers with internal organisers, a hidden electrical socket for your toothbrush, and a designated spot for every daily essential. If you're adding open shelving, treat it like a display space rather than storage, a few carefully chosen trinkets in natural materials make more impact than a cluster of products. Incorporate a med-cabinet behind your mirror for those less-than-photogenic necessities, and consider built-in shower niches that keep shampoo bottles off the floor. The goal isn't minimal living, it's smart storage that lets you keep everything you need within reach while maintaining that calm, collected hotel feeling. https://pin.it/5Z0CdyDQk Add a Touch of Greenery Boutique hotels know that greenery connects you to that holiday feeling faster than any design trick. Choose plants that love steamy conditions, a cascading fern creating shadows in your shower alcove, a glossy lily thriving on your vanity, or a statement monstera commanding attention in a corner. Try to think beyond the basic bathroom plant, keep your pots simple in natural materials like terracotta or concrete. And here's the insider tip; one oversized plant makes more impact than several small ones. https://pin.it/1T0gAwx18 Finish with Personal Touches Creating a boutique hotel-inspired bathroom is about focusing on the elements that matter most, whether that's a rainfall shower that drenches away stress or perfectly positioned lights that make every reflection flattering. Keep your palette restrained, your storage smart, and your materials honest. When each element serves both form and function, you'll create a space that feels like your own personal sanctuary, no room service required.

Remodeling Your Bathroom - 20 Frequently Asked Questions Answered By Our Experts
Remodelling Your Bathroom - 20 Frequently Asked Questions Answered By Our Experts 1. What are the first steps in planning a bathroom remodel? The first steps in planning a bathroom remodel involve setting a clear vision and budget. Start by identifying your needs and preferences, such as the desired layout, fixtures, and style. Create a detailed list of the changes you want to make and prioritise them. Research the costs associated with these changes to develop a realistic budget. Next, measure your bathroom space to ensure your plans will fit. Consulting with a bathroom design professional can help refine your ideas and provide valuable insights. Finally, gather quotes from contractors to compare prices and services, and choose a reputable one to begin your remodel. 2. How do I set a realistic budget for my bathroom remodel? Start by researching the average costs of bathroom renovations in your area, considering factors like materials, labour, and design complexity. Break down your budget into categories such as fixtures, flooring, plumbing, and electrical work. Allocate a portion of your budget for unexpected expenses, typically around 10-20%, to cover any unforeseen issues that may arise during the project. Prioritise your spending on essential items and features that add the most value to your bathroom. Comparing quotes from multiple contractors can help you get a fair price and avoid overspending. Keeping a detailed budget plan and tracking your expenses throughout the project will ensure you stay within your financial limits. 3.What are the latest trends in bathroom design? The latest trends in bathroom design focus on creating a spa-like atmosphere with modern, luxurious touches. Key trends include: Minimalist aesthetics - Clean lines, uncluttered spaces, and a focus on functionality. Natural materials - Use of stone, wood, and natural fibres to bring an earthy feel. Bold colours - Dark, moody colours like navy and forest green, balanced with lighter tones. Smart technology - Integration of smart showers, touchless taps, and heated floors. Freestanding tubs - Elegant and statement-making, these tubs add a luxurious touch. Large format tiles - Reducing grout lines for a seamless look and easier cleaning. Black fixtures - Matte black taps, showerheads, and hardware for a modern, sleek appearance. 4. How can I maximise space in a small bathroom? Maximising space in a small bathroom involves clever design and storage solutions. Here are some tips: Opt for wall-mounted sinks, toilets, and vanities to free up floor space. Install shelves, cabinets, and towel racks higher up on the walls to utilise vertical space efficiently. Large mirrors can create the illusion of more space by reflecting light and making the room appear larger. Consider sliding doors for showers and cabinets to save space otherwise taken up by swinging doors. Choose a cloakroom basin and furniture designed for small spaces. Use clear glass for shower enclosures to maintain an open feel. Incorporate built-in niches and shelves for storage within the shower and above the toilet. 5. What are the best materials for bathroom flooring? The best materials for bathroom flooring are those that offer durability, water resistance, and ease of maintenance. Popular options include porcelain and ceramic tiles, vinyl flooring, natural stone or engineered wood. Each material offers unique benefits, so choose one that fits your style, budget, and maintenance preferences. 6. Should I choose a walk-in shower or a bathtub? Choosing between a walk-in shower and a bathtub depends on your needs and bathroom space. Walk-in showers are ideal for small bathrooms, offering accessibility, modern aesthetics, and easy maintenance. They can be designed with various features like rain showerheads and built-in benches, providing a spa-like experience. Bathtubs, on the other hand, are perfect for relaxation and are great for households with young children. They add a touch of luxury and can increase the home's resale value. If space and budget allow, a combination of both a walk-in shower and a bathtub offers the best of both worlds. 7. What is the best type of lighting for a bathroom? The best type of lighting for a bathroom combines ambient, task, and accent lighting to create a well-lit, functional space. Ambient lighting provides overall illumination and can be achieved with ceiling-mounted fixtures or recessed lights. Task lighting is essential for grooming activities and should be placed around mirrors, typically in the form of wall-mounted sconces or LED strip lights. Accent lighting highlights architectural features or decorative elements and can be achieved with spotlights or under-cabinet lights. You might consider using dimmer switches to adjust the lighting levels and create a relaxing atmosphere. 8. How do I ensure proper ventilation in my bathroom? Installing an exhaust fan is the most effective way to ensure adequate ventilation. Choose a fan with the right capacity for your bathroom size, measured in cubic feet per minute (CFM). The fan should vent directly to the outside, not into the attic or another interior space. Additionally, open windows and doors after showering to allow fresh air circulation. Regularly clean the exhaust fan and check for any blockages to maintain optimal performance. 9. What adds most value to a bathroom? High-quality fixtures and fittings, such as modern taps, showerheads, and toilets, are essential. Installing energy-efficient and water-saving features, like low-flow showers and dual-flush toilets, can attract eco-conscious buyers. Adding underfloor heating and a heated towel rail provides luxury and comfort. Ample storage solutions, such as built-in cabinets and vanity units, maximise space and organisation. A fresh coat of paint in neutral tones, new tiles, and updated lighting can transform the look of the bathroom. Overall, a well-designed, functional, and stylish bathroom definitely boosts a home’s value. 10. Do I need planning permission to renovate my bathroom? In the UK, planning permission is generally not required for standard bathroom renovations, such as updating fixtures, tiling, or plumbing. However, if your renovation involves structural changes, altering the property’s exterior, or expanding the bathroom size, you may need planning permission. Always ensure that electrical and plumbing work complies with building regulations and is carried out by certified professionals. 11. Is it easy to renovate a bathroom? Simple updates, such as painting, replacing fixtures, or installing new accessories, can be manageable DIY projects. However, more extensive renovations involving plumbing, electrical work, or structural changes require professional expertise. Hiring a qualified contractor can streamline the process and ensure the work meets building regulations and quality standards. 12. How often should you renovate your bathroom? Renovating your bathroom every 7-10 years is a general guideline to keep it looking fresh and functional. However, the frequency can vary based on several factors, including the quality of the original materials, the level of wear and tear, and changing personal preferences or lifestyle needs. Regular maintenance and small updates, such as repainting, replacing worn fixtures, and re-caulking, can extend the time between major renovations. If you notice persistent issues like leaks, mold, or outdated plumbing, it might be time for a more comprehensive renovation. 13. How can I create more storage space in my bathroom? Install wall-mounted cabinets and shelves to keep essentials within reach without taking up floor space. Use the area above the toilet for additional shelving or cabinets. Incorporate built-in niches in the shower for toiletries. Opt for a vanity unit with drawers and cabinets to store items out of sight. Use baskets, organisers, and trays to keep smaller items tidy. Mirrors with integrated storage can also help. 14. What are the best paint colours for a bathroom? The best paint colours for a bathroom create a relaxing and refreshing atmosphere. Light and neutral tones are popular choices as they make the space feel larger and brighter. Whites, soft greys, and beiges provide a clean and timeless look. Pale blues and greens evoke a sense of calm and tranquility, reminiscent of water and nature. For a more dramatic effect, consider darker shades like navy or charcoal, balanced with lighter accents. 15. How do I prevent mold and mildew in the bathroom? Preventing mold and mildew in the bathroom involves controlling moisture and maintaining cleanliness. Ensure good ventilation by using exhaust fans and opening windows to reduce humidity. Clean surfaces regularly with mold-inhibiting cleaners and wipe down wet surfaces after use, especially shower walls and floors. Keep grout lines sealed to prevent moisture from seeping in, and apply mold-resistant paint to walls and ceilings. In particularly humid bathrooms, using a dehumidifier can help keep moisture levels in check. 16. What are the most durable materials for bathroom walls? Durable materials for bathroom walls must withstand moisture and frequent cleaning. Ceramic or porcelain tiles are highly durable and water-resistant, available in various styles. Acrylic panels are easy to install, water-resistant, and low-maintenance. Glass tiles offer a stylish, water-resistant, and easy-to-clean option. Vinyl wallpaper is moisture-resistant and available in various designs, making it suitable for bathrooms. Moisture-resistant paint is specially formulated to resist moisture and mould. Beadboard or wainscoting adds texture and style and is best when treated with water-resistant paint or sealant. These materials provide long-lasting and aesthetically pleasing wall coverings for bathrooms. 17. How do I choose the right mirror for my bathroom? Select a mirror that fits the scale of your vanity and bathroom, as larger mirrors can make small spaces feel bigger. Match the mirror style with your bathroom décor, whether it's framed, frameless, or decorative. Functionality is also crucial; consider mirrors with integrated lighting, storage, or anti-fog features for added convenience. 18. How can I make my bathroom more accessible for people with disabilities? Install grab bars near the toilet, shower, and bathtub to provide support. Choose a walk-in shower with a low or no threshold and consider adding a built-in or fold-down shower seat. Non-slip flooring throughout the bathroom is essential to prevent falls. Use adjustable showerheads mounted on a sliding bar for ease of use. Opt for a comfort-height toilet, which is taller than standard models, to reduce strain when sitting and standing. Ensure storage solutions are within easy reach, and consider widening doorways to accommodate wheelchairs or walkers. 19. How can I make my bathroom more eco-friendly? Start by installing water-saving fixtures, such as low-flow showerheads, dual-flush toilets, and aerated taps, which significantly reduce water consumption. Opt for energy-efficient lighting, like LED bulbs, to lower energy use and electricity bills. Choose sustainable materials for your bathroom renovation. Recycled glass, bamboo, and reclaimed wood are excellent choices for countertops, flooring, and cabinetry. Consider using eco-friendly paints with low or zero VOCs (volatile organic compounds) to improve indoor air quality. For a greener cleaning routine, switch to natural cleaning products that are free from harsh chemicals. These are safer for both your health and the environment. Lastly, ensure proper ventilation to prevent mould growth and reduce the need for chemical cleaners. By making these changes, you can create a bathroom that is both stylish and environmentally responsible. 20. How do I choose the right vanity for my bathroom? Start by measuring your bathroom to determine the appropriate vanity size. For small spaces, compact units like the 450mm vanities are ideal, while larger bathrooms can accommodate wider units like the 1200mm double sink options. Match the vanity style to your bathroom décor—34 St John offers a variety of finishes, including walnut, oak, and numerous colours. Functionality is crucial; look for vanities with ample storage, such as multiple drawers and shelves, to keep your space organised. Finally, ensure you choose a high-quality vanity within your budget, as investing in durable materials will provide long-lasting value.
