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.

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.
