What changes the cost of bathtub installation?
In Cheshire, the cost of bathtub installation depends on the type and weight of the bath, whether it fits the old position and pipework, the floor underneath, the taps, waste and panel, and how much tiling and making good is needed. We print no fitting price, so compare quotes for the same bath and work.
Last reviewed:What fitting a bath involves
Installing a bath means more than setting it on the floor. The fitter usually turns off the water, takes out the old bath and any panel or boxing, checks the floor, sets the new bath level on its feet or cradle, fits the taps and waste, connects the water supply and the waste pipe, fits the panel, seals the edges and tests for leaks. Tiling and decorating may follow.
The bath you choose changes almost every step: how heavy it is, how it sits, where the taps go and whether it needs a panel.
QuoteZila is starting in Cheshire, with Crewe, Nantwich and Sandbach among the first towns. This guide prints no fitting price. It explains what makes one bath quote larger than another, so you can compare them fairly.
Types of bath
- Acrylic straight bath. Light and common, usually set against a wall with a front panel. The simplest to fit like for like.
- Steel bath. Heavier than acrylic and rigid. Fitted in a similar way.
- Shower bath. Wider at the shower end, often P-shaped or L-shaped, with a screen. Needs careful sealing.
- Corner bath. Sits across a corner, often with a curved panel.
- Freestanding bath. Stands on its own, often in the middle of the room or against one wall, with no panel. The pipes may need to come up through the floor, and floor-standing taps are common.
- Cast iron or stone resin bath. Very heavy, especially when full. Needs a strong floor and several people to carry it in.
Ask each fitter to quote for the same model, or at least the same type and size.
Same position or a new one?
A bath going back in the same place usually reuses the existing waste and water pipes, with small changes for a different tap layout or waste position. Moving the bath, or swapping a bath for a freestanding one in the middle of the room, can mean lifting floorboards, rerouting the waste with a proper fall, and running new pipes.
The Planning Portal says a bathroom refit with new fittings does not generally need building regulations approval, but drainage or electrical work within it may, and creating a new bathroom where there was none is likely to [S1]. Ask your fitter whether your plans need approval.
The floor and the weight
A bath full of water is heavy, and a heavy bath with a person in it puts a big load on a small area of floor. On a timber upstairs floor, joists that have been notched for old pipes, or boards softened by past leaks, may not be up to a cast iron or stone bath.
Ask the fitter to check the floor once the old bath is out, and to tell you what happens if it needs repair or strengthening. If you are set on a very heavy bath, ask a builder or structural engineer about the floor before you buy.
Taps, waste and hot water
- Tap position. Deck-mounted, wall-mounted or floor-standing taps each need different pipework.
- Waste and overflow. A new bath may need a new waste kit, and a click or pop-up waste is fitted differently from a plug and chain.
- Hot water. A large bath needs a lot of hot water. Ask whether your boiler or cylinder can fill it at a sensible rate.
- Temperature. In a newly built home, or one formed by a change of use, Approved Document G says the hot water to a fixed bath must not exceed 48°C, usually met with an in-line blending valve or similar device [S2]. It can still be worth asking about in an existing home, especially with young children or older people in the house.
WaterSafe runs a register of approved plumbers you can search by postcode [S3].

What changes the cost of bathtub installation
| What is being priced | What makes it bigger or smaller | What to ask |
|---|---|---|
| Removing the old bath | Boxed in, tiled panel, cast iron to break up | Whether removal and disposal are included |
| The new bath | Type, size, weight, who supplies it | Which bath, and how it will be carried in |
| Position | Same place, or moving the waste and pipes | What pipework changes are included |
| Floor | Sound, needs repair, needs strengthening | What happens if the floor is damaged |
| Taps and waste | Deck, wall or floor-standing taps; waste type | Which taps and waste are included |
| Panel and screen | Front panel, end panel, shower screen | Whether these are included |
| Tiling | Repairs round the bath, or new tiles | Who does the tiling and is it priced |
| Sealing and making good | Silicone, decorating, flooring | Where the price stops |
| Access | Stairs, tight landing, heavy bath | How many people are needed to carry it |
| VAT | Whether the business is VAT registered | Whether the total includes VAT |
A business must register for VAT when its taxable turnover goes over £90,000 [S4]. Ask whether each total includes VAT.
Bath fitting in Cheshire
When you post the job, include the bath you want or its size and type, photos of the current bath and the walls around it, and whether the bathroom is upstairs. A bathroom fitter or plumber covering Crewe, Nantwich, Sandbach and the villages around them can then say whether it is a straight swap and how many people it will take to carry the bath in.
If you want a freestanding bath where there was a fitted one, mention it, because that is a different job. Anyone in the UK can still post a job or register a business on QuoteZila.
How long the bathroom will be out of use
A straight swap of an acrylic bath can often be done in a short visit, with sealant left to cure before the bath is used. A bath that involves new pipework, floor repairs, tiling or a freestanding layout takes longer, and the bathroom may be out of use for several days. If it is the only bathroom in the house, ask each fitter how long you will be without a bath or shower, and whether they can keep the toilet working throughout.
Ask too how the old bath will leave the house. A cast iron bath often has to be broken up where it stands, which is noisy and messy, so ask about dust sheets and protecting the stairs and landing.
What to have ready before you ask for quotes
- the bath you want, with its size and weight if you know them
- whether you are buying it yourself
- photos of the current bath, the taps, the panel and the walls
- whether the bath is staying in the same position
- which floor the bathroom is on, and the width of the stairs and doors
- the taps and waste you want
- any tiling you want done at the same time
- your postcode, and when the work could be done
How to compare bath quotes
Check each quote for:
- The bath, taps and waste named, and who supplies them.
- Removal and disposal of the old bath.
- Any pipework changes.
- What happens if the floor needs repair.
- Panel, screen, tiling and sealing.
- How the bath will be carried in.
- Whether VAT is included, and whether it is a fixed price.
Citizens Advice suggests getting written quotes from at least three traders and not agreeing to a deposit of more than 25% [S5]. If the fitter is ordering the bath, agree in writing what the deposit covers.

Questions about bathtub installation costs
How much does bathtub installation cost?
This guide does not print a fitting price. Taking out the old bath, the new bath's type and weight, the floor, the taps and waste, the panel, tiling and making good all change the total. Ask fitters to price the same bath and the same list of work.
Is a like-for-like bath swap a simple job?
It is usually simpler than moving the bath, because the waste and water pipes are already in place. It grows if the old bath is boxed in behind tiles, the floor under it is damaged, or the new bath is a different size or shape.
Can my floor take a cast iron or stone bath?
A heavy bath full of water and a person is a big load on a timber upstairs floor. Ask the fitter whether the floor needs checking or strengthening, and if there is any doubt, ask a builder or structural engineer before you buy.
Do I need building regulations approval to replace a bath?
Usually not for a straight swap. The Planning Portal says a bathroom refit with new fittings does not generally need approval, but drainage or electrical work within it may, and creating a new bathroom is likely to. Ask your fitter if you are moving pipes.
Does a new bath need a temperature limiter?
In a newly built home, or one formed by a change of use, Approved Document G says the hot water to a fixed bath must not exceed 48°C, usually with a blending valve. For a replacement in an existing home, ask the fitter whether one is a good idea for your household.
Will tiles need replacing when the bath is changed?
Often some will. Tiles that run down behind the bath edge can crack when the old bath comes out, and a new bath of a different height or shape leaves gaps. Ask whether tiling repairs are included, and keep spare tiles if you have them.
Does QuoteZila check the fitters who quote?
No. We don't check insurance, qualifications or registrations, so please check these yourself before you hire. You can report a quote or a business from your job page.
