Bath Installation Costs UK — What to Charge to Supply and Fit a Bath in 2026

What the Job Actually Involves

Before you can price a bath fit, you need to be clear on scope. A bath installation isn't just lifting one tub out and dropping another in. A typical job includes removing the old bath, positioning and levelling the new one on its feet or cradle, connecting hot and cold supplies to the taps, fitting the waste and overflow, sealing the bath to the wall, and reinstating the bath panel. On a like-for-like swap that's often the whole job. But the moment the new bath is a different size, a different style, or sits differently against the wall, you pick up extra work: moving the waste, extending or re-routing supply pipework, boxing in, and re-tiling or making good the wall.

The single biggest pricing mistake is quoting the "swap" price for what is really a "swap plus making good" job. Always inspect before you commit a figure.

• Disconnect and remove the old bath (often the messiest, most time-consuming part)
• Position, level and secure the new bath on feet, legs or a cradle
• Connect hot and cold supplies to the taps and check for leaks
• Fit the waste, trap and overflow assembly
• Seal the bath-to-wall and bath-to-floor junctions with sanitary silicone
• Refit or supply a new bath panel, and box in pipework if needed
• Make good or re-tile the splashback where the old bath line has changed

Labour Price Bands and Worked Examples

Labour is where you make your money on a bath fit, so it pays to band the work honestly rather than quoting a single round number. Below are the three scenarios that cover the vast majority of jobs, with worked examples.

1. Straightforward like-for-like swap — £250–£500 labour

A standard acrylic bath coming out, a same-size standard acrylic bath going in, with the existing waste and supply positions reused and minimal tiling disturbance. This is a half-day to a day for one fitter. Example: customer's 1700mm acrylic bath is tired and stained; you supply nothing but labour, reuse the existing taps if they're sound, fit the new bath, re-seal and refit the panel. Price this at £250–£500 depending on region and how cleanly the old waste releases. London and the South East sit at the top; the bath releasing without seizing or cracked tiles keeps you at the bottom.

2. Steel, freestanding or pipework-move job — £500–£900+ labour

Step up to a heavier steel bath, a freestanding bath, or any job where the waste and supplies need moving, new taps are fitted, or boxing-in is required. Steel baths are heavier and less forgiving on levelling; freestanding baths often need the waste brought up through the floor in a new position and exposed pipework finished neatly. Example: a freestanding double-ended bath replacing a built-in corner bath — you re-route the waste through the floor, run new supplies to a floor-mounted or wall-mounted filler, and make good the floor and walls. That's comfortably a full day or more and prices at £500–£900, rising above £900 where the pipework is buried in a solid floor or the filler is a complex floor-standing unit.

3. Bath area as part of a bigger refit — priced into the job

When the bath is being fitted alongside a part-tiled wall, a new panel, a screen and a shower over the bath, the bath labour stops being a standalone line and becomes part of a larger quote. Here you're tiling the splashback or full height, fitting a bath screen, and sealing multiple junctions. The bath element of the labour might be £400–£700, but it sits inside a job that also carries tiling at £40–£70/m² and the cost of the screen, taps and shower valve. Quote the bath, the tiling and the fittings as separate lines so the customer can see what they're paying for and you don't bury margin.

The Cost Split: Bath Unit, Taps and Labour

If you're supplying and fitting, the customer is paying for three things: the bath unit, the taps and waste, and your labour. Being clear on each helps you mark up materials sensibly and avoid the trap of absorbing supply costs into a labour figure that then looks too high.

The bath unit

• Acrylic (standard built-in): £120–£350. Light, easy to handle, the default for most swaps. A reinforced or twin-skinned acrylic sits at the top of this band.
• Steel enamel: £200–£500. Heavier and more durable, holds heat well, but needs careful levelling and two people to lift.
• Freestanding (acrylic or stone resin): £500–£2,000+. The bath itself is often the headline cost on these jobs and stone-resin or composite tubs run well into four figures.
• Whirlpool / spa: £700–£2,500+. Adds a pump and jets that need a fused spur, electrical connection and access for servicing — a different scope from a plain bath.

Taps and waste

Bath taps or a bath filler run from £40 for budget mixers to £300+ for premium or floor-standing fillers. A bath waste, trap and overflow kit is typically £20–£60. Customers often forget these when they buy "a bath" online, so make sure your quote spells out whether taps and waste are included.

Labour

As covered above, labour runs £250–£500 for a clean swap and £500–£900+ for steel, freestanding or pipework-move jobs. On a supply-and-fit quote, present labour separately from materials so a customer who wants to buy their own bath can still see your fitting price clearly.

What Pushes the Price Up

Two bath fits that look identical on paper can differ by hundreds of pounds in real labour. These are the variables to check on site before you quote — each one can turn a half-day into a full day.

• Access: A first-floor bathroom up a tight stairwell, or a bath that won't fit through the door in one piece, adds time and sometimes a second pair of hands. Freestanding and steel baths are heavy and awkward.
• Removing the old bath: Seized waste connectors, rusted-in steel baths, or a bath tiled solidly into the wall can mean cutting the old unit out and breaking tiles — budget extra labour and disposal.
• Moving waste or supply pipework: If the new bath's waste or tap positions don't match the old ones, you're into re-routing pipes, which is the most common reason a swap tips into the higher band — especially under a solid floor.
• Boxing in: Concealing pipework with a timber and board frame, ready for tiling or a panel, adds materials and a few hours.
• Tiling and sealing: Changing bath size or style almost always leaves a gap or a tile line that needs making good. Re-tiling the splashback is a separate skill and a separate cost.
• Wall and floor condition: Damp, crumbling plaster or rotten floorboards behind the old bath must be put right before the new one goes in. Flag this as a potential extra rather than swallowing it.

How to Quote a Bath Installation

A clear quote protects your margin and your reputation. The aim is to set out exactly what's included so there are no awkward conversations on the day. Work through this checklist before you send a price.

• Inspect first. Look at the existing waste, supplies and tile line. Decide whether the new bath reuses them or forces a move — that single fact sets your labour band.
• State who supplies what. Make it explicit whether the bath, taps and waste are supply-and-fit or customer-supplied. Note that you can't warranty parts you didn't supply.
• Separate labour from materials. Give a clear labour figure and a clear materials figure, with a sensible markup on what you supply.
• List exclusions. Spell out that re-tiling, repairing damp or rotten floors, and electrical work for a whirlpool spur are extras, quoted once exposed.
• Add a contingency line for the unknown. Removing an old bath can reveal seized fittings or hidden damage — a small allowance or an hourly rate for unforeseen work saves the argument later.
• Confirm disposal. Skip or tip-run charges for the old bath and packaging should be in the quote, not absorbed.

Send the quote as an itemised document rather than a single number. A customer who can see the bath, the taps, the labour and the making-good as separate lines is far less likely to haggle, and far more likely to accept extras when the old bath comes out and reveals a problem.

Frequently Asked Questions

How long does it take to fit a bath?

A clean like-for-like acrylic swap is typically a half-day to a day for one fitter. A steel or freestanding bath, or any job needing the waste and supplies moved, is usually a full day or more. Add time if tiling or making good is involved.

Should I charge labour-only or supply-and-fit?

Both are fine — just be clear which you're quoting. Supply-and-fit lets you mark up the bath, taps and waste, but you carry the warranty on those parts. Labour-only is simpler and suits customers who've already bought their bath, but always inspect what they've bought before agreeing a fitting price.

Why is a freestanding bath so much more to fit?

The bath itself costs more, it's heavier and harder to handle, and the waste and filler usually need re-routing through the floor with exposed pipework finished neatly. That combination pushes a freestanding fit into the £500–£900+ labour band, above a simple built-in swap.

Do I need an electrician for a whirlpool bath?

A whirlpool or spa bath has a pump that needs its own fused spur and an electrical connection that must comply with bathroom zone regulations. Unless you're qualified for that work, price in an electrician and a serviceable access panel as part of the job.

What if the old bath is tiled in?

A bath tiled solidly into the wall often has to be cut out, which breaks the surrounding tiles and adds labour, disposal and making-good. Flag this on inspection and quote the re-tiling as a separate, clearly stated extra.
