The short answer
A wet room adapted for a disabled user in the UK typically costs around £6,000–£10,000, with larger or higher-specification projects ranging up to £15,000 where structural changes or premium finishes are involved. An accessible wet room is a fully level, kerb-free room with the whole floor waterproofed (tanked) and gently drained, plus anti-slip flooring, grab rails and a shower seat — features that make it safer than a general wet room. The work is usually zero-rated for VAT for a disabled person and may be eligible for the Disabled Facilities Grant following an occupational therapy assessment. The figure depends on the room size, the drainage and the level of adaptation.
A wet room removes every step and edge, which is why it suits wheelchair users and anyone who finds a tray awkward. The accessible version costs a little more than a plain wet room because of the extra safety features. Here is what to expect.

Why an accessible wet room costs more
A wet room is built by tanking (fully waterproofing) the floor and walls and setting a gentle fall to a drain, so the whole room can get wet safely. An accessible wet room adds the features a disabled user needs: a fully level, kerb-free entrance for wheelchair access, anti-slip flooring, grab rails positioned for the individual, a fold-down or fixed seat, and a thermostatic valve. These extras, and sometimes a wider doorway or extra floor area for a carer, are why an adapted wet room sits above a general one in price.

Funding and the accessible angle
Because an accessible wet room is squarely a disability adaptation, it is usually zero-rated for VAT and is often eligible for the Disabled Facilities Grant (up to £30,000 in England) after an occupational therapy assessment. The OT can advise whether a wet room or a level-access shower better suits the person — a wet room is often recommended where a wheelchair is used or a carer needs floor space. Where the work is grant-funded, the assessment determines what is included, so it is worth starting that conversation with your council before committing.
