A mobility wet room can be a fantastic feature to add to any house and when used to improve the life of someone with mobility difficulties, it can have a hugely positive impact.
It’s one of those changes that quietly removes daily stress, especially around bathing and getting around safely.
But before ordering your wet room, there are some things to consider.
Rushing this stage usually causes problems later on, especially around space, drainage and long-term usability.
Here are some key considerations:
Location
One of the first considerations should be where your wet room should be located in your house.
While the initial temptation will be to replace your existing bathroom, it’s worth stepping back and thinking about day-to-day use.
Will your existing bathroom offer the access required for the person(s) using the wet room?
Also, the location will play a key part in most of the other considerations that we will cover.
Pipework, floor levels and even how easy it is for someone to get in and out of the room all depend on this choice more than people expect.
If access is awkward or involves too many steps, even the best wet room design won’t feel right in practice.
Size & Layout
Building on the location consideration, you’ll need to ensure your new wet room has all the space required for it to be functional and efficient.
Think about showers, toilets, basins, handles/handrails and even towel rails.
You may also need to factor in mobility hoists, depending on who is using the wet room.
This is where real day-to-day comfort is decided. If space feels tight, movement becomes harder, especially for wheelchair users or carers assisting with bathing.
Even small layout changes, like shifting a basin or widening a turning space, can make the room feel completely different in use.
Drainage
One of the key aspects of a successful wet room is the drainage capabilities.
When deciding where your wet room will be and how it will be constructed, it’s important to factor in where the drainage will go and how it will work.
Typically, there will be one drain in the room with a slight slope that allows water to run to it.
Beneath the floor, a wastewater pipe will then need to take the drained water away.
This pipe needs a fall of at least 1:40, so make sure your proposed room location allows for this to be built in without hampering accessibility.
If this is not right, the water doesn’t clear properly. It starts pooling, slows everything down and becomes an ongoing frustration that’s difficult to fix later.
Wet Room Flooring
Another important consideration is the type of flooring you will use.
Flooring for wet rooms is most commonly seen in two variations.
They are tiled and vinyl.
Vinyl is easy to install and highly slip-resistant; however, it can look a little cold and industrial as it is often used in medical facilities and commercial properties.
Tiles offer a much wider choice, but consider factors such as slip-resistance ratings and grout maintenance.
A bathroom designed to support mobility and accessibility mustn’t introduce new risks to the user. A floor that looks fine and dry can become very different once water is involved.
Waterproofing
If your waterproofing is wrong in a wet room, then the entire project will be flawed.
Ensure that your plans, or those of the installer, include an impermeable membrane which covers the entire wet room area, including at least a metre beyond the showering area.
Also, ensuring that all corners and joints are sealed is vital.
This stage is usually hidden once finished, so it needs to be done properly from the start. If it isn’t, leaks don’t always show immediately, but they do cause damage over time.
It’s the part of the job that protects everything else.
Ventilation
Finally, ventilation is very important in any bathroom, so getting it right in your new wet room should be a top priority.
A lack of ventilation can lead to mould and other bacteria forming and given how wet rooms are designed, it’s really important to ensure every area that comes into contact with moisture is well ventilated.
A decent extractor fan, correctly sized for the space, makes a noticeable difference. It helps the room dry properly after use and keeps surfaces from staying damp longer than they should.
