How much does a walk-in bath cost?
A walk-in bath with a door, built-in seat and hydrotherapy jets typically costs £6,000 fitted, including VAT, with most quotes between £4,700 and £7,800. The price covers taking out the old bath, the new bath, taps and waste, plumbing and a dedicated electrical circuit for the pump. A plain soaking walk-in bath without jets is around £3,350; a model with air and water jets, a heated seat and a fast-drain pump is nearer £9,800.

What affects the cost
Soaker, whirlpool or combination
A plain soaking walk-in bath has no electrics beyond what the room already has. Hydrotherapy (water jet) and air-jet models need a pump, controls and their own protected circuit, and combination models with both systems sit at the top of the range.
Filling and draining time
You have to sit in the bath while it fills and empties, so the time taken matters more than on an ordinary bath. Wider taps and a pumped fast-drain shorten the wait, and a heated seat or back keeps you warm, but each adds cost.
Hot water capacity
Walk-in baths are deep and hold more water than a standard bath. A combi boiler fills slowly at its flow rate, and a small cylinder may run out before the bath is full. Upgrading the hot water system is not included here and can be a significant extra.
Size and fit
Compact models fit the space of a standard bath; longer or wider ones, or a model with the door on the other side, may mean moving pipework or re-tiling around the new shape. Measure the doorways and stairs too, as the bath arrives in one piece.
Door design and seal
Inward-opening doors are held shut by water pressure; outward-opening doors are easier to get past but rely more on the latch and seal. Ask how the seal is replaced and what it costs, since it is the part that wears.
Tiling and making good
The quote covers the bath itself. If the new bath is a different height or footprint, the surrounding tiles and panelling may need redoing, which is priced separately.
How to save
- Decide whether you need jets at all: a plain soaking model with a good seat and grab handles costs far less and has fewer parts to maintain.
- Choose a model that fits the existing bath space and keeps the waste in the same place.
- Ask about the 5% or zero VAT rate before you sign, so the relief is on the invoice rather than claimed afterwards.
- Get at least three quotes, including one from an independent plumber for fitting a bath you buy yourself, and compare the warranty on the door seal.
Grants, tax and rules
VAT relief for disabled people and people aged 60+
Our figures include 20% VAT. People aged 60 or over can get 5% VAT on the supply and installation of a walk-in bath with a sealable door. Adapting a bathroom because of a disabled person's condition can be zero-rated (HMRC Notice 701/7, checked September 2026). The installer applies the rate, usually after you complete a short eligibility declaration.
Disabled Facilities Grant
Councils can fund bathroom adaptations for disabled people through the Disabled Facilities Grant: up to £30,000 in England, £36,000 in Wales and £25,000 in Northern Ireland. It is means-tested for adults and an occupational therapist decides what is needed; a level-access shower is often recommended instead of a bath.
Electrical work
The pump and heater need a new circuit, which in England and Wales must be done by a registered electrician (Part P) or notified to building control.
Frequently asked questions
How much does a walk-in bath cost fitted?
A mid-range walk-in bath with hydrotherapy jets costs around £6,000 fitted, including VAT, with the dedicated electrical circuit. A basic soaking model is around £3,350, and a top model with air and water jets and a heated seat is nearer £9,800.
Is a walk-in bath better than a walk-in shower?
A walk-in shower is usually cheaper, quicker to use and suits most people with limited mobility. A walk-in bath is worth it if you value a soak for pain or stiffness and can step over a low threshold and sit while it fills and drains.
How long does a walk-in bath take to fill and drain?
Longer than an ordinary bath, because it is deeper and you are already inside. How long depends on your hot water system and the tap and waste sizes; ask the supplier for the fill and drain times with your type of boiler or cylinder.
Can I get a walk-in bath with 5% VAT?
Yes, if you are 60 or over, a walk-in bath with a sealable door qualifies for 5% VAT on supply and installation. If the bath is fitted because of a disabled person's condition, it can be zero-rated instead.
Does a walk-in bath need its own electrical supply?
Models with jets, pumps or a heater need a dedicated RCD-protected circuit, which is included in our mid and premium figures. A plain soaking model needs no electrics.
How long does fitting take?
Usually one to two days for a like-for-like swap: removing the old bath, fitting and levelling the new one, connecting water and power, then leak-testing the door. Tiling or pipework changes add time.
