Small Bathroom Renovation Cost by Spec
For a small room the biggest variables are the fittings you choose, whether the layout stays put, and how much tiling you want. Keeping the suite in the same position and tiling only wet zones is the cheapest route. Here is the 2026 ladder.
Budget refit (like-for-like)
£3,000-£4,500. Standard suite, mixer shower, part-tiled walls, vinyl or LVT floor, same layout. The lowest-cost route to a fresh, functional bathroom.
Mid-range refit
£4,500-£6,000. Better suite, thermostatic shower, fully tiled wet areas, quality flooring and a heated towel rail. The most popular spec for a small family bathroom.
Premium finish
£6,000-£8,000+. Designer fittings, large-format or feature tiling, walk-in glass screen, underfloor heating and recessed storage. Best where a small en-suite adds real value.
Labour breakdown
Around half the total. Plumber £300-£800, tiler £300-£900, electrician (Part P) £250-£600, plus fitting and making good. A multi-trade bathroom fitter often bundles these.
Moving the layout
Relocating the toilet, basin or shower means new pipework and drainage - add £500-£1,500. Keeping fittings where they are is the single biggest saving on a small bathroom.
Hidden costs to check
Removing the old suite and waste (£150-£400), fixing damp or rotten floorboards, upgrading extract ventilation, and re-plastering. Get these confirmed on the quote.
