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

Small bathrooms — what people ask
How much does it cost to renovate a small bathroom?
£4,000 to £6,500 excluding VAT for a full renovation of a typical small south London bathroom (under about 4m²). Small does not mean half the price of a big room — the trades, waterproofing, certification and most of the labour are the same; you save mainly on tiles and materials. The FMB's national average for a small bathroom is £4,250, and London sits at the top of any national range.

The moves that genuinely work: wall-hung basin and toilet so the floor runs unbroken to the wall; a single large mirror rather than a cabinet-door mirror; large-format light tiles with matching grout so the surfaces read as planes rather than grids; glass shower panels instead of framed enclosures; and lighting in layers rather than one centre pendant. The floor showing at the edges of the room does more than any paint colour.
Read the full answerCan you fit a proper shower in a tiny bathroom?
Almost always. A 800×800 or 900×760 tray fits rooms people assume are bath-or-nothing, sliding doors remove the swing-space a hinged door needs, and in genuinely tight rooms a wetroom-style corner with a single fixed panel uses less floor than any enclosure. The constraint is usually the door swing and the toilet position, not the shower — which is why we draw the layout options before quoting.
Read the full answerIs it worth renovating the bathroom in a flat I rent out?
Usually, yes — the bathroom and kitchen are what listing photos live or die on, and a tired bathroom discounts rent every single month. For a rental we specify slightly differently: thermostatic showers that resist scale, standard-size sanitaryware that can be replaced item-by-item, fully tiled floors with tanking even outside the shower, and sealed storage. Spending £4,500 once beats re-sealing and patching every tenancy change.
