There is no single price, and a figure over the phone is a guess. But the things that move the number are predictable, so here is what you are actually paying for.
The tiled area, not the floor area
A 4 m² bathroom can have 20–25 m² of tiling once you count full-height walls, the floor, the bath panel and the window reveal. Wall area is what makes bathrooms expensive to tile, and full-height costs more than half-height.
The cost drivers, roughly in order
- Layout changes — moving the WC or soil pipe adds first-fix work and time.
- Tanking — a tiled shower needs a waterproof membrane behind it. Not optional.
- Substrate — soft floors, uneven walls and old screed all need work before tiling.
- Tile format and material — large-format porcelain and natural stone are slower to lay and need flatter substrates.
- Pattern — herringbone, chevron and mosaic add labour and waste.
Indicative ranges
As a guide for Greater London, TileDegree’s price for a full bathroom refit — labour, consumables, waste and waterproofing — typically starts around £9,500 and rises with size, layout changes and finish. On top of that you buy the sanitaryware, tiles and brassware, usually £1,500–£4,000 for a mid-range spec.
These are indicative market figures at the time of writing, not a quotation. The accurate number is a written quote after a survey.
