How Much Does a New Bathroom Cost in the UK?

Those ranges come from the major 2026 UK cost surveys — Checkatrade, the Federation of Master Builders, and trade pricing indices — all cited at the bottom of this page, cross-checked against what we actually quote on Teesside jobs. Below: what each budget buys, where the money really goes, what moves the price most, and a calculator to put a realistic range on your own bathroom before anyone visits.

What does each budget actually buy?

One counter-intuitive rule worth knowing: small rooms don't scale prices down proportionally. The fixed costs — strip-out, waste removal, first-fix plumbing, waterproofing — are the same whether the room is 3m² or 8m², which is why a compact en-suite can cost more per square metre than a large family bathroom.

Where does the money actually go?

Labour takes 45–60% of the total on a typical project — a full bathroom needs a plumber, tiler and usually an electrician across 5–10 working days, and fitting labour alone commonly runs £1,500–£3,000. The suite itself is often the smallest slice: a solid mid-range toilet, basin and bath or shower from established UK brands costs £1,000–£3,000 all-in, while budget sets start around £400–£600. The remainder goes on tiling and flooring (materials and the considerable labour to fit them), waterproofing, electrics and ventilation, and waste disposal.

This split is why two quotes for “the same bathroom” can differ by thousands — they're rarely pricing the same scope. One includes making good the walls, moving a radiator and a building-regs-compliant extractor fan; the other quietly excludes all three. Always compare quotations line by line on scope, not bottom line alone.

What changes the price the most?

1. Moving things. Keeping the toilet, basin and bath where they are is the single best money-saver in bathroom fitting. Relocating a toilet — even a metre — means new drainage runs and can add £600–£1,500 on its own.

2. Wet rooms and waterproofing. Converting to a proper wet room adds tanking, a former tray and floor drainage — typically £2,500–£4,500 over an equivalent shower room. It's also the work where corner-cutting causes the most expensive failures later, which is why we photograph tanking before tiling on every wet area we build.

3. The age of your property. Older Teesside housing — Victorian terraces in Stockton, 1930s semis, even some 1970s estates — often hides corroded pipework, uneven floors or crumbling walls that only appear at strip-out. Experienced fitters price realistic contingency for the housing stock they know; suspiciously low quotes usually haven't.

4. Tiling decisions. Full-height tiling on every wall versus wet areas only adds £700–£1,600 in materials and labour, and large-format or natural stone tiles cost meaningfully more to fit properly than standard ceramics.

What do bathrooms cost on Teesside?

National guides bury the most useful fact in a footnote: where you live moves the price more than most fixture choices. London runs 15–30% above the UK average; the North East sits at the other end of the table. Trade day rates across the North East run about £180–£220 against a national average near £245 — and since labour is roughly half of any bathroom project, finished prices on Teesside typically land 8–15% below the national figures above. Materials cost broadly the same everywhere, so a £7,000 national-average bathroom often prices at £6,000–£6,500 in Stockton, Thornaby, Ingleby Barwick or Yarm — the calculator's Teesside toggle applies exactly this adjustment.

We're publishing a full local breakdown — what bathrooms cost on Teesside vs the national average — with figures from our own completed projects across the area.

How to keep the cost down without regretting it

Keep the layout. Choose mid-range fittings from established brands — the £2,000 difference between mid-range and designer brassware buys almost no extra lifespan. Limit full-height tiling to where it earns its keep. Get quotes in writing with the scope itemised, and treat a fixed written price as non-negotiable — if a quote can grow after work starts, it wasn't a real price. What not to economise on: waterproofing, ventilation, and whoever does the work. A £500 saving on tanking is the most expensive money ever saved in a bathroom.
