Improving Your Bathroom Layout

There’s plenty to think about when designing your bathroom layout. Here are some quick tips to get you started:

●     What to include: Do you really need a bathtub? Bear in mind that a shower requires 40% less floor space. What about a single or double vanity? Or a fitted or handheld bidet? Much will depend on how much space you have available.

●     Sizing: Consider using smaller fixtures and fittings. The standard depth of a vanity unit is typically 1 ft 8 inches[1]  (50 cm), but you could opt for a 1 ft (30 cm) unit to create extra floor space in tight rooms.

●     Zoning: Break your room into wet and dry zones. Your wet area should have adequate waterproofing, while your dry zone should provide enough space for towel-drying and dressing.

●     Movement and flow: You should be able to effortlessly move around your bathroom, switching from one task to another with ease. Avoid obstructions like awkward door swings. Fit an in-wall sliding door to create less of a bottleneck.

●     Positioning: Think about where to place your bathroom fittings in relation to each other. For example, it makes sense to have a mirror above your vanity, a towel rail next to your shower, and a bidet next to your toilet.

●     Toilet design: A wall-mounted model will make floor cleaning easier while also adding a modern touch. Use a concealed in-wall cistern to save on space.

●     Privacy: Consider the line of sight when opening the door and be sure to use frosted glass on any windows or doors. Think about soundproofing measures like a door sweep or in-wall insulation.

Best bathroom layout for privacy

●     Accessibility: For older or less able family members, install grab bars around your shower and toilet area. You may also want to widen the doorway, install non-slip tiles, and fit an elevated toilet.

●     Storage: There are plenty of bathroom storage options available, from shelving and rails to hooks and cupboards. You can even fit a wall-mounted soap dispenser in your shower to avoid clutter.

Common Bathroom Layout Dimensions

Here are some standard dimensions to help you layout your bathroom fittings. For more accurate measurements, remember to check your specific models before finalizing any plans.

A standard tub is 2 ft 6 inches by 5 ft (76 cm by 152 cm). If you have a larger room, wider 3 ft (92 cm) models are available. You can also opt for a shorter 4 ft 6 inches (137 cm) tub to fit a smaller room.

 Soaking tubs are designed for a more relaxing, comfortable soak, so they are larger than standard tubs. You’ll need at least 3 ft by 6 ft (92 cm by 184 cm) available if you want to splash out on one of these more luxurious fixtures

Standard bathtub dimensions


A shower can be as large as you want to make it (especially when in a wet room environment). But for enclosed showers, we recommend you have at least 2 ft 6 inches square (76 cm).

For a larger shower, you can increase this to 3 ft 6 inches square (106 cm). This should make washing your body more comfortable and help avoid any elbow knocks for taller people.

Standard shower dimensions


2 ft 6 inches square  (76 cm) should be plenty of space to fit a standard toilet. If you have any accessibility issues, the width can be increased to 3 ft (92 cm).

Opting for a concealed cistern or wall-mounted model will save you about 1 ft in depth (30 cm).

Minimum dimensions toilet


A single vanity unit requires at least 2 ft of width by 1 ft 8 inches of depth (61 cm by 51 cm). But, if you have the space, we recommend a larger surface or even a double vanity. This will give you plenty of room to store all those bathroom accessories.

You’ll need at least 5 ft (152 cm) of width if you want to upgrade to a double vanity.
