If you have been browsing bathroom inspiration lately, you have probably come across the term “wet room” more than once. They are one of the most requested bathroom styles we see at our Caterham showroom, and for good reason. A wet room can make a small space feel bigger, add real value to your home, and solve accessibility problems that a standard bathroom simply cannot. But before you commit, it helps to understand exactly what a wet room involves, what it costs, and whether your bathroom is actually suited to one.
In this guide, we will answer the question we get asked most, what is a wet room, and walk through the practical details: how it compares to a standard bathroom, what you should budget for, and why so many of our accessibility clients across Surrey choose this layout.
What is a wet room?
A wet room is a fully waterproofed, level-access bathroom where the shower area is open to the rest of the room, rather than boxed in behind a screen, tray or enclosure. Instead of stepping up and over into a shower cubicle, you walk straight in. The floor is tanked (waterproofed) underneath the tiles and gently sloped towards a drain, so water runs away naturally without pooling.
The key difference from a shower room is that a wet room has no raised shower tray at all. Everything, walls, floor and sometimes the ceiling, is treated to be completely watertight before any tiling goes down. This is what makes wet rooms more involved to install than a standard shower, but it is also what gives them that clean, seamless, almost hotel-spa look that so many homeowners want.
Wet rooms work particularly well in smaller bathrooms and en-suites, where a shower enclosure would eat up valuable floor space, and in homes where step-free access matters. If you are still deciding on the overall layout of your bathroom, our team can talk you through the options as part of our bathroom design service.
Wet room vs standard bathroom
The biggest difference comes down to waterproofing and layout. A standard bathroom relies on a shower tray, sealed edges and a screen to contain water in one area. A wet room waterproofs the entire floor and lower walls, so water can go anywhere in the room without causing damage.
Here is how they compare in practice:
- Shower access: a standard bathroom means stepping over a tray or bath, a wet room is fully level with no step at all.
- Waterproofing: a standard bathroom relies on localised sealing around the tray and screen, a wet room has the whole floor and lower walls tanked.
- Visual space: a standard bathroom is broken up by the tray and screen, a wet room gives you one open, continuous floor.
- Best suited to: standard bathrooms work well for family bathrooms with a bath, wet rooms suit en-suites, small bathrooms and accessible bathrooms.
- Installation complexity: a standard bathroom is a moderate job, a wet room is more involved and needs specialist tanking and floor build-up.
- Resale appeal: a standard bathroom is widely expected by buyers, a wet room is increasingly desirable, especially as a downstairs shower room.
Neither option is “better” across the board. A family bathroom that needs a bath for young children will usually keep a standard layout, while an en-suite or a bathroom being adapted for easier access tends to suit a wet room far better.
How much does a wet room cost?
Wet room costs vary depending on the size of the room, the current floor structure, the tiles and fittings you choose, and whether any plumbing or drainage needs to be moved. As a general guide, here is what UK homeowners typically budget for:
- Small en-suite wet room (basic tiling, standard fittings): £4,500 to £7,000
- Mid-size wet room (mid-range tiles, glass screen, underfloor heating): £7,000 to £11,000
- Large or bespoke wet room (premium tiles, bespoke joinery, wet room dryer): £11,000 to £18,000+
- Accessible wet room with level access and support rails: £6,500 to £12,000
The main cost drivers are the floor build-up (lowering or adjusting joists to create the fall towards the drain), tanking materials, tile size and finish, and whether you want extras like underfloor heating or a wet room dryer unit. Ground floor installations are usually more straightforward and cheaper than upper floor conversions, which may need more structural work to achieve the drainage fall.

Wet rooms for accessibility & level access
This is where wet rooms genuinely change lives, not just aesthetics. For anyone with reduced mobility, a level access wet room removes the single biggest hazard in most bathrooms: the step or ledge into the shower. There is nothing to trip over, nothing to lift a leg over, and plenty of room to manoeuvre a wheelchair or walking frame if needed.
We regularly design accessible wet rooms for clients across Caterham, Reigate, Oxted and the wider Surrey area, working alongside features like grab rails, fold-down seating and slip-resistant flooring to create a bathroom that is safe without feeling clinical. Good design means these features blend into the overall look rather than standing out.
If a wet room is not the right fit for your household, perhaps because you still want the option of a soak, it is worth looking at our range of accessible and walk-in bath options, which offer similar safety benefits with a more traditional bathing experience.
Is a wet room right for you?
Wet rooms suit homes with the right underlying structure, a genuine need for level access or a compact space, and a budget that allows for proper waterproofing rather than shortcuts. They are not the cheapest option on the market, but done properly, they last for decades and add genuine appeal when it comes to selling your home.
The best way to know if your bathroom is a good candidate is to have it assessed in person. Book a visit to our Caterham showroom or get in touch with our team to talk through your space, your budget and what a wet room could look like in your home.
