Full bathroom installation in Wandsworth

Complete rip-out and refit — plumbing, electrics, tiling and fit-out, one team start to finish.

Fully renovated bathroom with freestanding bath and metro tiling
Bathroom installation in Wandsworth

A Tonsleys bathroom refit is the tightest full installation we do: back-addition rooms around 3m², single-skin external walls that need insulating and tanking, and a floor void so shallow that waste runs are planned to the centimetre. The result photographs like a boutique hotel precisely because everything is wall-hung and built-in — the room allows nothing else. Southfields refits are gentler: square Edwardian rooms, deep joists, and space for a bath *and* a separate shower, which is the conversion most owners there ask for.

The houses we see in Wandsworth

The Tonsleys are 1850s–1870s two-up-two-downs where the bathroom is nearly always in the back addition — small, single-skin walls, external stack, minimal floor void. Southfields' Edwardian grid has proper first-floor bathrooms and generous structure. Earlsfield is heavily converted to flats, where bathrooms sit on split supplies with sub-metering and shared stacks. The riverside developments are new-build leasehold with concierge processes and no-cut slabs.

What bathroom installation involves

A full bathroom installation in south London costs £5,000–£9,000 excluding VAT and the suite, and takes two to three weeks. That covers rip-out, first-fix plumbing and electrics, waterproofing, tiling, fit-out and certification — the labour-only figure national guides quote at £2,000–£4,000 buys a like-for-like swap, not a full renovation.
