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
Measure Your Bathroom: Begin by measuring your bathroom's dimensions, including the length, width, and height. Accurate measurements will help you identify the available space for the bath.
Consider the Layout: Analyse your bathroom's layout. Note the locations of windows, doors, and fixtures such as sinks, toilets, and showers. This will help you identify where the bath can fit without obstructing access or natural light. It is also important to know where your soil stack is as this can dictate where you need to have the bath, toilet, shower etc.
-
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.
