Small Wet Rooms

Having limited room needn’t stop you from having your perfect wet room. It just means that it’s time to get smart about how you organise the space available. Wet rooms are highly adaptable and allow even the most compact of spaces to be transformed into a luxury wet room.


How Small Can a Wetroom Be?

To give you an idea, the smallest practical wetroom size is 1.5m x 1m with enough space for a toilet and wash basin too. The minimum recommended size for the shower area alone is 70cm x 70cm, so removing the loo and wash basin means you can have plenty of room to manoeuvre, especially if you have mobility issues or are designing a wetroom for someone who does. However, if you’re looking for a luxurious wetroom area, you’ll want to find way to maximise space. This can be done through careful planning of toilets, sinks and showers. Likewise, if you already feature a bath in the small space, you can upgrade it with a walk-in shower instead.

Wetrooms are ideal for small spaces, despite the social media images of luxury homes suggesting otherwise. With the right plumbing and drainage in place, many homes in the UK have adopted a small wetroom as it offers greater convenience.


What Do You Need to Know About Small Wetroom Designs?

Keeping the water contained is also important. Spray can be restricted with a hinged or static glass partition that keeps your fittings dry, but this isn’t essential. When waterproofing wetrooms, at a minimum the shower area and one additional metre surrounding it should be tanked, a wetroom measuring 1.5m x 1m would require the whole space to be waterproofed.

What Can a Small Wetroom be Used For?

Aside from offering a functional space to place a toilet or walk-in shower, a small wetroom can be tailored to meet your requirements. Whether you require greater ease for mobility purposes or desire a luxurious spa look within your home, the choices are endless.

Many people choose to turn otherwise redundant spaces into wetrooms, offering greater convenience and use of space. As well as being easy to maintain, they also provide homes with hygienic showering solutions as they require less cleaning than a typical bathroom. This is simply because shower water has a greater reach than traditional bathrooms. However, drainage systems and mould buildup do need to be monitored regularly.

Wetroom Design Ideas for Small Shower Rooms

Making the most of your wetroom space is vital, and ensuring it’s completely functional is also a must. A small wetroom can be achieved by converting the cupboard under the stairs or even a disused airing cupboard into a compact shower room. There are plenty of options since a wetroom offers you unrivalled versatility and creativity.

A wetroom shower also lets you make use of architectural quirks in a room’s shape that might otherwise go to waste. Your space needs to work as a waterproofed area that offers excellent comfort, manoeuvrability and efficiency. That’s why shower trays and baths might not always offer the best flexibility, especially when they can take up considerable space.

Replenish a Redundant Room

Make the most out of your wetroom through clean dividing lines and sections specifically allocated for their purpose. Combining a walk-in shower, wash basin and toilet all in one room is an excellent way to rejuvenate otherwise redundant spaces.

Luxurious Spa Appearance

Through sleek lighting and reflective surfaces, you can make your small wetroom space embrace a relaxing ambience. Ensuring light is able to reflect from all surfaces will create a calm, yet spacious, impression.

Create a Contemporary En Suite Design

Introducing a wetroom into your en suite offers convenience and comfort, especially for guests staying in the room. If you’re contending with a sloped ceiling too, this ensures an impressive use of space that might have otherwise been lost.

Offer Freedom and Mobility

If you simply need an accessible space that offers you the support you need, a small wetroom can be adapted to fit mobility requirements. From seats to grippy floor textures, various modifications and installations can readily be included.


Small Wet Room Product Considerations

There are a number of important considerations you should be aware of when installing a wetroom. Each of these ensures correct installation and maintenance of your wetroom down the line.


Tanking is the technical term for the waterproofing of your small wetroom. An impermeable rubberised membrane with interwoven glass fibre is used to completely seal the wetroom’s floor and walls, eliminating the ingress of water. When done correctly this prevents the room from leaking and will last throughout the tiles’ lifetime.


Creating falls (another name for the gradient that channels the water to the drain) is important too. The falls can either be achieved on timber floors with pre-formed decs and floor formers, or in wetrooms on solid floor build-ups, by pouring screed to the correct falls. The gradient created must be at least 11mm below the height of the floor to ensure the water drains into the traps.

Small Wet room Drainage

Your small wetroom’s drainage capacity is vital. A shower which pumps in water faster than the drain can remove it is a recipe for disaster if left unattended. Shower heads with higher flow rates need additional traps to remove the excess water and prevent flooding.


Adequate ventilation will remove excess moisture from the air and prevent the formation of mould, and structural dampness. A popular ventilation option for small wetrooms is passive stack ventilation which allows moisture to escape without the associated loss of heat.
