Small bathroom renovation in Wandsworth
Making tight Victorian and flat bathrooms work harder — layout, storage and light, not just new tiles.

This is the Tonsleys' native service — most bathrooms here are small bathrooms, and the renovation playbook is at its sharpest: sliding pocket doors into stud walls where the wall build allows, 1500mm baths or shower-only layouts, boxing the external stack into a niche, and mirror-fronted storage across the full basin wall. In Earlsfield's converted flats the small bathroom is usually internal — no window — so we duct extraction to the rear elevation properly instead of relying on the previous conversion's flexible hose into the ceiling void.
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 small bathrooms involves
A small bathroom renovation in south London costs £4,000–£6,500 excluding VAT and takes one to two weeks. Most south London bathrooms are small — the back-addition bathroom of a Victorian terrace is typically under 4m² — and the wins are layout moves: a short-projection toilet, wall-hung basin, over-bath shower or walk-in tray, and every centimetre of wall used for storage.
This is for you if
- The bathroom is under 4m² and feels cramped however clean it is
- A bulky airing cupboard or old layout is eating half the room
- You want a shower but think the room is too small for one
- The only storage is a wobbly freestanding cabinet
- A dark internal bathroom with no window
- A rental flat bathroom that needs to survive tenants
What's included
- Layout options drawn before you commit — usually three ways to use the room
- Space-saving sanitaryware: short-projection WCs, wall-hung basins, sliding glass
- Built-in storage in the dead zones — over the door, in stud walls, boxed pipework
- Light-maximising finishes: large mirrors, reflective tiles, glass over solid
- Proper extraction sized for a small volume — the mould killer
- Full strip-out to fit-out in one to two weeks
The standard we work to
Same regulations as any bathroom: Part P electrics in zones, Part F ventilation — small rooms need the extractor most.
