How To Plan Your Bathroom Layout By Our Design Experts
Designing the perfect bathroom starts with smart layout planning. Whether you’re working with a small space or a large master bathroom, the right layout can transform how your bathroom functions and feels. This guide walks you through essential ideas and tips to create a layout that maximises both form and function, tailored to your needs.
Assess your needs and space
Before choosing a layout, measure your bathroom and decide what you need from the space. For smaller bathrooms, compact layouts can make the space more functional by using wall-mounted fixtures or corner sinks. For larger bathrooms, you have the flexibility to incorporate both a freestanding bathtub and a walk-in shower.
Accurately measure your bathroom
No bathroom renovation can get started without this all-important first step. Here’s how you should do it.
- Gather your tools: a measuring tape, pen or pencil and somewhere to write down your measurements
- Measure your bathroom’s length and width, wall to wall. Make a note of the measurements (in millimetres for the greatest accuracy)
- Measure your bathroom’s height, floor to ceiling. Make a note of the measurement
- Take all three measurements again to double-check
- If necessary, measure all of your bathroom fixtures and fittings, including doors and windows – double-checking the measurements

Now that you have your measurements, you can start figuring out which layout you want to go with.
Bathroom layout ideas
Here are some ideas collected from our bathroom design experts:
Small bathroom layout ideas
https://pin.it/5ZE1EbsZ5
Compact shower over bath: If space is tight, consider combining the shower and bath in one area. Use a transparent glass door to keep the room feeling open.
Wall-mounted fixtures: Choose wall-hung vanities and toilets to free up floor space, making the room feel larger.
Corner sink & toilet placement: Positioning sinks or toilets in corners opens up more central space, creating a better flow.
Large bathroom layout ideas
Separate shower and bath zones: In larger bathrooms, creating separate zones for the shower and bath can give the room a more luxurious feel.
Double basin vanities: If space allows, installing two sinks is a practical option, especially for shared bathrooms.
Central focal points: A freestanding bath or large walk-in shower can serve as the centrepiece of your layout, surrounded by storage or seating areas.
Family-friendly layout ideas
Dedicated storage zones: Install built-in shelving or cabinets to ensure that all family members have designated storage.
Open floor space: Ensure there’s plenty of room for movement, especially in bathrooms used by multiple people.
Functional zones: Separate the vanity area from the shower/toilet for better usability during busy mornings.
The way you position your bathroom fixtures has a significant impact on the overall efficiency and functionality of the space, and don’t forget, there are some practical considerations beyond aesthetics.
Here are some layout-efficient positioning tips:
Toilet positioning: Always place the toilet as close as possible to the existing soil pipe. Moving the soil stack can be expensive and complex, so it’s best to work with your current plumbing setup. A corner placement or positioning the toilet against an exterior wall can help keep plumbing simple and the layout compact.
Sink location: Position the sink near existing water supply and drainage lines to minimise the need for costly plumbing alterations.
Shower placement: For both practicality and aesthetics, place the shower at the far end of the bathroom. This maximises space and keeps wet areas away from the entryway, reducing splash zones. If possible, align the shower with existing water and drainage lines to avoid rerouting pipes.
Bathtub positioning: If including a bathtub, it’s important to place it near both the hot and cold water supply, and ideally, the existing waste pipes. In larger bathrooms, a central freestanding bathtub can serve as a focal point, but ensure it remains close enough to the plumbing infrastructure to avoid modifications.
Maximise wall space for storage: Use vertical wall space to add storage units, cabinets, or wall-mounted towel rails. This keeps the floor area clear, especially in small bathrooms.
Consider clearances for usability: Ensure there’s enough clearance around fixtures for easy movement. For example, leave at least 60cm of free space in front of the toilet and sink for comfort. Consider where doors (both entry and cabinet) will swing to avoid awkward collisions with fixtures.
Reasons to work with your existing plumbing
Provided that your existing plumbing is in good working condition, there are many big reasons why you should stick with it for your bathroom renovation.
- Save money. Moving or altering plumbing lines can be very expensive – especially if you need professional help
- Save time. On top of money, removing and creating new plumbing is a time-consuming process that will lengthen your project timeline
- Reduce risk. Changing your plumbing can compromise the structural integrity of your home if not done properly, increasing the risk of damage to your home's structure
- Fewer or no new permits. Making changes to your plumbing often requires you to obtain new permits from your local authority – costing you more time and money
Map out your floor plan
Now you have an idea of where you want to place your fixtures and how you want your bathroom to look, you can start to map out the floor plan.
You can either:
Sketch your bathroom to size - map out the bathroom space according to the measurements you took. Measure your toilet, sink, shower, bath etc and draw them to size.
Use a 3D layout mapping tool - tools like Flooplanner, or Ikea’s bathroom mapping tool can plot these measurements accurately and visualise your bathroom layout in 3D.

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.
