Bathroom Cost Calculator

Bathroom renovation costs in the UK — what to expect

As a general guide, typical full bathroom projects at Carvalho Renovations tend to start around £8,000, while larger or premium renovations — walk-in showers, underfloor heating, full-height feature tiling — can exceed £25,000. As with kitchens, the calculator above builds a range from your actual selections rather than interpolating between those two figures.

Sanitaryware choice and tiling extent/complexity are usually the biggest cost drivers — a walk-in shower and full-height feature tiling cost meaningfully more than a standard shower enclosure and half-height splashback tiling, even in an identically sized room. Whether the existing bathroom needs full removal, and whether plumbing needs relocating, also has a real impact on labour cost.

The calculator opens on Full bathroom renovation with a sensible baseline already selected — removal of the old bathroom, core sanitaryware, a realistic tiled area, plumbing/electrical work and waterproofing — since that reflects what a proper renovation genuinely involves. If you're only after lighter refurbishment work (retiling, swapping sanitaryware, no strip-out), switch to Partial bathroom refurbishment at the top for a starting point that reflects that instead.
