What actually drives the cost of a new bathroom in Northampton

The short answer

Two UK cost guides put a standard family bathroom at about £4,500 to £9,000, fitted. The size of the room matters less than you might think. The suite, the tiling, any pipework moves and access set most of the price.

Guide prices from two sources

Bathroom Mountain gives £4,500 to £9,000 for a standard bathroom. Drench puts a mid-range refit at £5,000 to £8,000. Both guides cover supply and fitting.

Labour is a large part of the bill. Bathroom Mountain suggests £1,800 to £4,000, and Drench quotes £250 to £500 a day. Drench says a refit takes about a week, while Bathroom Mountain says six to ten working days. The stages run in order, so ask for a timeline with your quote.

These are guides for the UK as a whole. They are not our prices, so ask for a written quote for your own room, since every bathroom differs.

The suite is the biggest variable

Two rooms of the same size can end up far apart in price, because the reason is nearly always the choice of fittings.

• Sanitaryware. A close-coupled toilet takes less time to fit than a wall-hung unit with a hidden cistern.
• Shower type. A basic mixer shower is a different job from a digital or power shower.
• Tiling. Half-height tiles are quicker than floor-to-ceiling tiles on every wall.
• Flooring. Tiled floors need a level base and waterproofing first.
• Heating. A heated towel rail is a simple swap, while underfloor heating adds work.

Hot water matters too, because the shower needs a supply that suits it. Our water tank and cylinder page explains how stored hot water affects flow. If you plan a new cylinder, see the hot water cylinder cost guide.

Like-for-like or a new layout

The biggest cost lever is whether the layout changes. A like-for-like swap keeps the toilet, basin and bath where they are. Pipes stay put, so there is less first-fix work and less mess.

A new layout costs more because pipes and waste runs must move. Turning a bath into a walk-in shower is a common example. A toilet moved to another wall may need a new waste route, and in some homes a macerator is the answer. Our guide to Saniflo faults explains how those units behave.

What a bathroom installation involves

Our bathroom installation service follows a set order.

1. Strip out the old suite, tiles and floor.
2. First fix: new pipes, waste runs and any electrics.
3. Tile and waterproof the wet areas.
4. Second fix: fit the suite, taps and shower.
5. Test the water, the drains and the extractor before sign-off.

Delays usually arise at first fix, because the old suite can hide worse pipework than expected. Old leaks may still show up. Our guide to the signs of a burst pipe lists what to look for before you start. Drains matter as well, since a refit may expose a weak run, and a CCTV drain survey can check it first.

Building rules and the right trades

Some bathroom work needs notifying. Approved Document G covers hot water safety, and drainage changes can also count. Check with building control or a competent person scheme for your job. The government page on Approved Document G is the place to start.

Ask each trade what they will cover and what they will not. Our guide on how to choose a plumber lists the checks to make. Landlords refitting several rooms may also like our notes on commercial plumbing.

Plan for the unexpected

Set aside a cushion in your budget, since hidden damp, old pipes and rotten boards all cost extra to fix. If a leak appears mid-job, our emergency first 10 minutes guide tells you what to do. Meanwhile, the emergency plumber cost guide shows what out-of-hours help may cost.

If you buy an older home and plan a refit, a pre-purchase drain survey shows what lies below the floor. The cost of a CCTV survey is small next to a bathroom budget.

Frequently asked questions

How long does a bathroom fit take?

Bathroom Mountain suggests six to ten working days for a standard room. A like-for-like swap is shorter than a new layout, although access can add time.

Should I supply the suite myself?

Either way works. Tell the fitter early, because it changes the quote. Check delivery dates, since a late tile can stall the job.

Does a small leak need fixing before a refit?

Yes, because tiling over a damp wall hides the fault. Fix the cause first. For smaller jobs, our tap and shower repair service can help.
