Accessible Bathroom Cost Calculator
Level-access adaptations are priced like a wet room plus the equipment. This prices both, and is honest about what a grant may and may not cover.

How this calculator works
The cost step that matters is removing the threshold. Grab rails and a seat are a few hundred pounds; a genuine level-access wet room means tanking the floor and building in a fall, which is why it lands in the same bracket as a full bathroom refit.
Specify with an occupational therapist where you can. It gets the details right — turning circles, rail heights, seat positions — and it is also the assessment a grant application is built on.
On grants: apply before work starts. A Disabled Facilities Grant is means-tested for adults and administered by your local council, and councils do not normally fund work that has already been done.
Almost the entire cost jump in an accessible bathroom comes from removing the threshold, because a true level-access shower is a tanked, fall-to-drain floor — the same build our wet room cost calculator prices in detail. Two things are worth confirming in writing before you commit. First, that the contractor will zero-rate the qualifying adaptations, since work for a disabled person is often VAT-free; our guide on whether a new bathroom is VAT-free explains what counts. Second, that any Disabled Facilities Grant is approved before the first day on site, as councils rarely fund work already done.

It can. A Disabled Facilities Grant is up to £30,000 in England and is means-tested for adults, so it may cover all, part or none. Children under 18 are not means-tested. Apply through your council before any work begins.
A walk-in shower still has a low tray with a small upstand. Level access has no threshold at all, which means the floor itself is tanked and falls to the drain — a different and more expensive job.
For a grant application, effectively yes — the council assessment is built on it. Even self-funding, an OT gets the rail heights, turning space and seat position right first time.
Adaptations for a disabled person are often zero-rated for VAT. Ask your contractor to confirm the position in writing and check the current HMRC guidance, as the rules are specific about what qualifies.
