The Short Answer
Replacing a bath with an accessible walk-in shower costs £6,000 to £10,500 from a specialist; a level-access wet room £8,000 to £14,000. In England, small adaptations such as grab rails should cost you nothing: after a free assessment, the council can't charge for an adaptation costing £1,000 or less.
Two things can cut the bill hard. Councils in England, Wales and Northern Ireland give Disabled Facilities Grants of up to £30,000, £36,000 and £25,000 respectively, and in Scotland the council pays at least 80% of essential adaptations. And adapting a bathroom for a disabled person is zero-rated for VAT. Don't start work before a grant is approved, or you may lose it.

What help you can get towards an accessible bathroom, from the rules on GOV.UK, HMRC and the Scottish Government.
Small adaptations: free
After a free assessment by the council's occupational therapist, the council can't charge for an adaptation costing £1,000 or less, such as grab rails or a small ramp (Care and Support charging regulations; NHS guidance).
Grant
A Disabled Facilities Grant of up to £30,000 from your council. It's means-tested on household income and savings over £6,000, so you may have to contribute.
VAT
0% VAT on adapting the bathroom, washroom or toilet to suit the disabled person's condition, and on the materials the installer supplies with that work. You sign a short declaration for the installer; it must be separate from the invoice.
Next step
Contact your council. An occupational therapist usually visits to assess what's needed, and the council must decide within 6 months. Foundations, an organisation the government funds for this, can help you apply.
Accessible bathroom prices
| Adaptation | Typical cost, installed |
|---|---|
| Grab rail | £35 to £120 each if you pay privately; Mole Valley District Council's handyperson service charges £34.30 for the first and £11.50 for each extra rail |
| Low-level bath | £6,000 to £8,000 |
| Walk-in bath with door | £6,000 to £12,000 |
| Walk-in shower (low tray, seat and rails) replacing a bath | £6,000 to £10,500 |
| Level-access wet room | £8,000 to £14,000 |
These are one specialist installer's prices (EA Mobility). I'd also get a quote from a general bathroom fitter, given the occupational therapist's specification, to compare. For a standard wet room price, see our wet room costs.
Free assessment and free small adaptations
Start with the council. The NHS explains that your local council offers a free home assessment by an occupational therapist, who visits, sees what you struggle with and works out with you what's needed. It usually takes at least an hour; have a friend or relative with you, or an advocate.
For bigger work, like a wet room or wider doors, there's the Disabled Facilities Grant below. A Home Improvement Agency can help you find other schemes. If you're unhappy with an assessment, complain to the council, then the Local Government and Social Care Ombudsman.
Disabled Facilities Grants
| Nation | Grant |
|---|---|
| England | Disabled Facilities Grant, up to £30,000 |
| Wales | Disabled Facilities Grant, up to £36,000 |
| Northern Ireland | Disabled Facilities Grant, up to £25,000 |
| Scotland | No DFGs. The council must give a grant for adaptations it assesses as essential: 80% of the cost, or 100% if you get certain benefits |
How a Disabled Facilities Grant works, from GOV.UK:
- Who: you or someone living with you must be disabled (physical or learning disability, age-related needs, autism, dementia, a progressive or terminal illness, or a mental health condition) and intend to live there for the grant period, usually 5 years. Owners, tenants and landlords can apply.
- Means test: based on household income and savings over £6,000; you may have to contribute. Grants for disabled children aren't means-tested on the parents, and landlords aren't means-tested.
- Process: apply to your council; an occupational therapist or assessor visits; the council must decide within 6 months. The work should be finished within 12 months of approval.
- Payment: in instalments or on completion, sometimes direct to the contractor. If a relative does the work, usually only materials are covered.
- It won't affect benefits.
In Scotland, the Scottish Government's homeowner guide dates from 2011 and its list of qualifying benefits predates Universal Credit, so confirm with your council which benefits give the 100% grant.
VAT relief: 0% and 5%
HMRC's VAT Notice 701/7 gives two different reliefs, and they're often muddled:
| 0% (zero rate) | 5% (reduced rate) | |
|---|---|---|
| Who | Someone chronically sick or disabled: a long-term, substantial impairment, or a condition treated as chronic (such as diabetes) | Anyone aged 60 or over |
| What | Providing, extending or adapting a bathroom (including a wet room), washroom or toilet to suit their condition, plus goods the builder supplies with that work | Grab rails, ramps, stairlifts, bath lifts, built-in shower seats or showers with them, walk-in baths with sealable doors, supplied and fitted by the same firm |
| Where | Their own home | Their own home (not a care home) |
| Not covered | Elderly people who aren't disabled; temporary injuries | General building work such as widening doors or extensions; repairs |
| How | A written declaration given to the installer, separate from the invoice | A written declaration given to the installer |
The 0% relief is worth a sixth of the price of a standard-rated job. On a £8,000 wet room that's about £1,333. A VAT-registered installer who does this work regularly will have the declaration form.
Getting the design right
I'd get the occupational therapist's assessment even if you're paying yourself: it's free, and their specification is what you give installers to quote against. Tell them everything you find difficult, even small things. For anyone who uses a wheelchair or shower chair, I'd go for level access, which means a wet room.

If you're applying for a grant, say so: the council has its own process and installers who know it will help.

Frequently asked questions
Are home adaptations free?
In England, after a free council assessment, adaptations costing £1,000 or less (grab rails, small ramps) should be free. Bigger ones may be covered by a Disabled Facilities Grant.
How much does it cost to adapt a bathroom for a disabled person?
From nothing for small adaptations the council provides in England, to £6,000 to £10,500 for a walk-in shower or £8,000 to £14,000 for a level-access wet room, installed by a specialist.
How much is a Disabled Facilities Grant?
Up to £30,000 in England, £36,000 in Wales and £25,000 in Northern Ireland. Scotland doesn't have DFGs; councils give a grant of 80% (or 100% on certain benefits) for essential adaptations.
Is a disabled bathroom VAT free?
Adapting a bathroom, washroom or toilet to suit a chronically sick or disabled person's condition in their home can be zero-rated under VAT Notice 701/7. You give the installer a signed declaration.
