Bathroom Renovation Costs in the UK: A Realistic Guide

Typical price ranges in 2026

For a straightforward like for like refit of a standard UK bathroom, roughly 2m by 2m, most homeowners should budget somewhere between £5,000 and £8,000 including labour, materials and waste removal. That covers stripping out the old suite, new bath or shower, basin, toilet, tiling to wet areas and redecoration.

A mid range renovation with better quality fittings, full height tiling, a new shower enclosure and perhaps underfloor heating typically lands between £8,000 and £12,000. Larger bathrooms, high end brassware, walk in showers with wet room tanking, or structural changes such as moving walls can push a project to £15,000 and beyond. Around Cardiff and the wider South Wales area, labour rates tend to sit a little below London prices, which helps, but material costs are broadly the same wherever you are in the UK.

• Budget refresh (new suite, minimal tiling): £4,000 to £6,000
• Standard full renovation: £5,000 to £8,000
• Mid range with full tiling and upgrades: £8,000 to £12,000
• Large, high spec or wet room conversions: £12,000 to £18,000+

What actually drives the cost

Labour is usually 40 to 60 percent of the total. A full renovation involves several trades: plumbing, tiling, electrics, plastering and sometimes joinery. A typical strip out and refit takes two to three weeks, and every extra day on site adds cost. Moving the position of the toilet, basin or shower is one of the biggest cost multipliers, because soil pipes and water feeds have to be rerouted under floors or through walls.

The other big variable is what turns up once the old bathroom comes out. In older Cardiff housing stock, particularly Victorian and Edwardian terraces, it is common to find rotten floorboards under a leaking bath, crumbling wall plaster, or old lead and imperial pipework that needs replacing before anything new goes in. A sensible quote will flag these risks in advance, but it is wise to hold back a contingency of around 10 to 15 percent of your budget for surprises.

Where to spend and where to save

Spend money on the things that are hard to change later: the quality of the tanking and waterproofing, decent pipework and isolation valves, and a tradesperson who will do the preparation properly. A cheap renovation that leaks into the ceiling below costs far more in the long run than doing it right the first time.

You can save meaningfully on the visible items without hurting quality. Mid priced sanitaryware from established UK suppliers performs almost identically to designer equivalents at three times the price. Large format porcelain tiles often work out cheaper to lay than hundreds of small ones because labour time drops. Keeping the layout as it is, rather than moving the toilet across the room, can save £500 to £1,500 on its own.

• Keep the existing layout where possible
• Choose mid range sanitaryware over designer labels
• Tile wet areas fully but consider painted walls elsewhere
• Do not skimp on waterproofing, valves or labour quality

Getting quotes and comparing them fairly

Get at least two or three itemised quotes, and make sure each one states clearly whether it includes materials, waste removal, VAT and making good afterwards. A quote that looks £1,500 cheaper often simply excludes the tiles, the plastering or the skip. Ask how long the job will take, who will be on site each day, and what happens if hidden problems are found.

Be a little wary of any figure given over the phone without a site visit. No installer can price a bathroom accurately without seeing the room, checking water pressure, and looking at where the soil pipe runs. A proper survey before quoting is a good sign that the final bill will match the estimate.
