When a standard bathroom becomes difficult or unsafe to use, there are three popular ways to make it accessible: a walk-in bath, a walk-in shower, or a full wet room. Each solves a different problem, and the right choice depends on your mobility, your space and your budget. This guide compares all three so you can decide with confidence.
The three options in brief
A walk-in bath has a watertight door so you can step in over a low threshold instead of climbing over a high bath wall, and you bathe sitting down. A walk-in shower is a low-threshold or level shower enclosure set within an otherwise normal bathroom. A wet room removes the tray and enclosure altogether, tanking the whole floor so it drains to a single point, which gives full step-free access.
Walk-in baths
A walk-in bath suits people who still enjoy a soak and have enough mobility to manage the inward-opening door and the seat. The low step makes getting in far safer than a conventional bath, and many models add grab rails, a built-in seat, and thermostatic controls. The main drawback is that you must sit in the bath while it fills and drains, which can feel cold, and you still need to negotiate a small step. Walk-in baths typically cost from around £2,000 for the bath alone, with supply and fitting often bringing the total to £4,000 to £7,000.
Walk-in showers
A walk-in shower is the most practical choice for most households. It uses a low-profile or level-access tray and frameless glass, so the rest of the bathroom stays dry. It is quicker to retrofit than a wet room, works well with a shower seat and grab rails, and keeps water contained. Expect a typical installed cost of around £3,000 to £6,000 depending on the tray, screen and any tiling, rising for premium fittings.
Wet rooms
A wet room offers the best accessibility of the three. With no tray and no step, it gives full wheelchair access and a clean, open feel that makes a small bathroom seem larger. The trade off is cost and disruption: the entire floor must be tanked (fully waterproofed) and laid with a gentle fall to the drain, which is more involved than fitting a tray. A wet room conversion typically costs £5,000 to £10,000, more if the room needs structural work or underfloor heating. It is the only option that, when built correctly, meets accessible-housing standards for wheelchair users without modification.
Side-by-side comparison
| Walk-in bath | Walk-in shower | Wet room | |
|---|---|---|---|
| Step-free access | Low step | Low or level | Fully level |
| Best for | Those who want to bathe | Most households | Wheelchair users |
| Wheelchair access | Limited | Possible | Excellent |
| Retrofit difficulty | Moderate | Lower | Higher |
| Typical installed cost | £4,000 to £7,000 | £3,000 to £6,000 | £5,000 to £10,000 |
How to choose
Start with the person who will use it most. If they want to keep bathing and can manage a small step, a walk-in bath makes sense. If safe, independent showering is the goal and budget matters, a walk-in shower is usually the best value. If a wheelchair is involved now or is likely in future, a wet room is the most future-proof choice. An occupational therapist can assess your needs and recommend the right option, and that assessment is often the first step towards funding.
Funding your project
A Disabled Facilities Grant from your local council can cover essential bathroom adaptations, up to a maximum of £30,000 in England, following an occupational therapist assessment. VAT relief also applies to adaptations for people who are disabled or chronically sick, which can save a meaningful amount.

Frequently asked questions
Which is cheapest to install?
A walk-in shower is usually the most affordable of the three, because it works within the existing bathroom without tanking the whole floor. A wet room is generally the most expensive due to the waterproofing involved.
Is a wet room a good idea in a small bathroom?
Yes. A wet room often works very well in a small space, because removing the tray and screen frees up the floor and makes the room feel larger and easier to move around.
Will an accessible bathroom add value to my home?
A well-designed walk-in shower or wet room is increasingly seen as a desirable feature, especially as the population ages, and can make a home more appealing to a wider range of buyers.
Can I get a grant for the work?
You may qualify for a Disabled Facilities Grant through your local council. An occupational therapist assessment is usually required, and the grant can cover essential adaptations up to the maximum in your nation.
