The same job costs more in London and the South East and less in the North, Wales and Scotland, mostly through labour rates.

Sources & Methodology

How we produced these figures

The cost ranges on this page come from BestBuilders’ 2026 regional cost model: published national cost guides adjusted by a regional labour index and averaged across 519 UK towns, then reviewed against published trade pricing. They are indicative ranges for a typical specification, not quotes — access, finish level and the builder’s workload move real prices either way.

Regulatory points (planning, Building Regulations, grants and VAT) are checked against current UK government guidance. Last reviewed: August 2026. Spotted something out of date? Tell us via the form above.

Before you commit

What actually moves a bathroom quote

The calculator gives you a fair range, but the spread inside it comes down to a handful of decisions. The first is whether you keep the layout. Leaving the bath, basin and WC where they are keeps the plumbing short and the walls intact; moving any of them means new hot and cold feeds, new waste runs, lifted floors and chased walls, then extra making good and tiling once it’s all back. That one choice is why two quotes on the same room can look so different.

Moving the WC is the change that bites hardest, because the soil pipe has to fall consistently to reach the stack. A basin or bath can often be shifted with modest pipework; relocating the toilet can mean boxing in a new run, dropping a floor or building the finished level up. If a quote for a ‘layout change’ looks high, the soil and waste routing is usually the reason.

Tiling is measured, not guessed. A fully tiled family bathroom has far more square metres than a half-tiled shower room, and the tile itself swings the figure – ceramic is cheap to buy and fix, while large-format porcelain and natural stone cost more in both material and labour because they’re heavier and slower to set. Underfloor heating under that floor adds a layer of its own.

A wet room is a different job again. Instead of a tray you tank the floor and walls to make them watertight, form a fall to the drain and often reinforce the floor first. That tanking, and the drying time it needs, is why a wet room sits above a like-for-like refit even at the same finish level.

Electrics are where a bathroom stops being cosmetic. New lighting, a shaver socket, an extractor to clear moisture and any electric shower or heated mirror all fall under the wiring rules for a room with water, and the work must meet Building Regulations. A competent electrician certifies it, and that certificate is worth having when you sell.

Most people are best served by a bathroom fitter who brings their own plumber, tiler and electrician, so one firm owns the sequence and the schedule. Hiring trades separately can save money on a simple like-for-like swap, but you carry the coordination and the risk if one trade’s slip stalls the next. Get three itemised quotes and check each covers waste removal and making good before you compare the bottom lines.

Frequently Asked Questions

How accurate is this bathroom cost calculator?

It produces a realistic 2026 budget range rather than a fixed quote. Figures are based on typical UK supply-and-fit rates by bathroom type, project scope and finish, with a low–high band (about ±15–20%) for variation in the suite, tiling and your fitter's rates. Use it to set a budget; a firm price follows an itemised quote and a look at your room.

What's included in a cosmetic, partial and full refit?

A cosmetic refresh (new suite in the same positions, retile, repaint) is the cheapest at roughly 55% of a full refit. A partial refit (new suite and tiling but keeping the layout and some fittings) is about 80%. A full refit (100%) strips the room back and replaces everything. A full refit with a layout change — moving the bath, WC or basin — adds about 50% for the extra plumbing and making good.

Why is there a low–high price range rather than one price?

Bathrooms of the same size differ hugely on suite quality, tile choice, whether you add underfloor heating or a walk-in shower, and local labour. The low figure reflects a budget suite and ceramic tiles; the high figure reflects premium fittings, large-format or natural-stone tiles and extras. The band is the realistic spread until your spec is quoted.

Does the estimate cover the suite, tiling and labour?

Yes — it is a supply-and-fit budget including the suite, tiling, fitting labour and VAT for the bathroom type and finish you pick. It excludes structural changes, moving soil pipes long distances and any work outside the bathroom, which a fitter would price separately on a quote.

What does moving the bath, basin or WC add?

Relocating fittings means new hot and cold feeds and waste runs, often lifting floors and chasing walls, plus extra making good and tiling. In the calculator that is the 'layout change' option, which adds roughly 50% over a like-for-like full refit. Keeping the suite in its existing positions is the cheapest way to refit.

Does the calculator estimate include VAT and waste removal?

The figures shown are guide estimates that assume standard 20% VAT on labour and materials, plus typical rubble skip and waste-clearance costs for a bathroom strip-out. They exclude structural work, moving soil pipes, asbestos removal or making good beyond the bathroom, so add a margin if your job involves any of those.

Why might a fitter's quote come in higher than this estimate?

A calculator works from average prices, but a real quote reflects your actual room, access, tile choice and any hidden problems found once tiles come off, such as rotten joists, leaking pipework or non-standard wall build-up. Older properties, upstairs bathrooms and awkward access all push a genuine quote above a typical guide figure.

Does the estimate change much by region or in London?

Yes. Labour rates drive most of the difference, so a bathroom fit in London and the South East often costs 20 to 40 percent more than the same job in the North or Midlands. Material prices vary far less. The estimate reflects a UK average, so adjust upward for London and downward for lower-cost regions.

How long does a new bathroom take to fit?

Most full bathroom refits take about 7 to 10 working days once the room is stripped out — a day or two for rip-out and first-fix plumbing and electrics, the middle days for tiling and drying, then second-fix, sealing and snagging at the end. A small cloakroom or a straightforward en-suite can be done in 4 to 6 days, while a layout change, wet-room tanking or replastering pushes a job past two weeks. Tile-setting and screed or tanking drying times usually set the pace, not the fitting itself.

Do I need one bathroom fitter or separate trades?

A dedicated bathroom fitter or a small firm usually handles the whole job and brings in their own plumber, tiler and electrician, which keeps the schedule tight and gives you one point of responsibility. Hiring trades separately can be cheaper on a simple like-for-like swap, but you then coordinate the order of work yourself and carry the risk if one trade's delay stalls the next. For anything involving moved plumbing, electrics near water (Part P) or a wet room, use someone who fits complete bathrooms regularly — and always check how to choose a bathroom fitter before you commit.
