Wandsworth bathroom renovation costs sit broadly in line with the South London average above outer boroughs, roughly level with Lambeth and Southwark. Premium specification works in Battersea, Putney, and Wandsworth Town regularly exceed the high-end range, reflecting higher-quality sanitaryware, bespoke tilework, and underfloor heating as standard.
What drives cost variation in Wandsworth:
– Scope: replacing sanitaryware and tiles only costs significantly less than a full strip-out with layout changes
– Bathroom size: a standard family bathroom in a Wandsworth Victorian terrace (4–6m²) costs less than a large master bathroom or principal suite
– Specification of off-the-shelf sanitaryware and ceramic tiles costs a fraction of designer fittings and large-format stone tiles
– Layout changes relocating the WC, basin, or bath require drainage rerouting, which adds high cost and may require building regulations notification
– En-suite creation: creating a new en-suite in a bedroom adds partition walls, a new drainage stack connection, and full electrical and plumbing first fix
– Wet room conversion: waterproofing a wet room to a professional standard requires a tanked system and typically costs more than a shower enclosure of equivalent specification
What does a bathroom renovation in Wandsworth typically involve?
Most Wandsworth bathroom renovations fall into one of four scopes:
Basic refit (£4,000-£8,000): sanitaryware replaced (bath, WC, basin, taps), tiles replaced on existing walls, floor tiling updated. No layout change, no drainage rerouting. Typical for Victorian terraces in SW17 and SW18 where the bathroom functions well and the goal is a cosmetic refresh.
Mid-range renovation (£8,000-£15,000): full strip-out, new sanitaryware, full retiling, new flooring, new lighting, extractor fan, and electrical upgrades. May include a new shower enclosure or replacing the bath with a shower tray. Heated towel rail and heated floor typically included at this level.
High-specification renovation or wet room (£15,000-£35,000+): bespoke tiling (large format, book-matched, or natural stone), designer sanitaryware, wet room with tanked waterproofing system, underfloor heating, demister mirror, recessed lighting. May include a freestanding bath or frameless shower enclosure. Common in Battersea, Putney, and Wandsworth Town on higher-value properties.
En-suite creation (£8,000-£20,000) converting part of a bedroom into a new en-suite bathroom. Includes partition wall, drainage connection to the existing stack, plumbing first fix, full tiling, sanitaryware, and electrical work. Cost depends on distance from the existing drainage stack and specification level.
What is typically included in a full bathroom renovation quote:
Item | Basic refit | Mid-range | High-spec/wet room
Sanitaryware | Mid-market brands | Mid-market to designer | Designer or bespoke
Tiling | Ceramic wall tiles | Porcelain floor and wall | Large-format stone or porcelain
Shower | Shower enclosure | Shower enclosure or tray | Wet room or frameless enclosure
Flooring | Ceramic or LVT | Porcelain or heated tile | Stone, heated underfloor
Lighting | Standard ceiling | Spotlights + LED | Fully designed scheme
Heated towel rail | May include | Yes | Yes, designer
Layout change | No | Possible | Possible
Planning required | No | No | No
No. A bathroom renovation including a full strip-out, new sanitaryware, new tiling, and new fittings does not require planning permission from Wandsworth Council.
Building regulations approval is required in certain cases:
– Electrical work: notifiable work under Part P must be certified by a registered electrician; a consumer unit upgrade or new circuit requires building control notification
– Drainage rerouting: relocating the WC, basin, or bath to a new position requires connecting to the drainage stack; this is building regulations notifiable if it affects existing drainage
– Structural changes: removing a structural wall to enlarge a bathroom requires a structural engineer and building regulations sign-off
– En-suite creation: creating a new en-suite in a bedroom is not planning notifiable but does involve notifiable electrical and plumbing work
Conservation area status does not affect internal bathroom works. External changes such as new windows or rooflights in conservation areas do require planning permission. Check planning.wandsworth.gov.uk if you are considering adding a rooflight above a bathroom.
Conservation area restrictions do not apply to internal bathroom renovations. The tiles, sanitaryware, layout, and fittings inside your home are unaffected by conservation area status.
Where conservation area rules do apply to bathroom projects:
– New roof windows or rooflights above a bathroom are permitted on rear roof slopes in some cases, but require planning permission in Wandsworth conservation areas
– New external windows changing the size, style, or position of a bathroom window on the front or side elevation require planning permission in conservation areas
– External extraction vents: visible extraction vents on front elevations require planning permission in conservation areas; a rear-elevation vent is generally acceptable
Key Wandsworth conservation areas affecting bathroom-linked external works:
Area | Postcodes/neighbourhoods affected
Battersea conservation areas | SW11 Lavender Hill, Clapham Junction, Battersea Park Road
Wandsworth Town | SW18 West Hill, Old York Road
Tooting Bec | SW17 Tooting Bec Road, Balham Hill
Balham | SW12 Bedford Hill, Balham High Road
Nightingale Triangle | SW12 between Clapham South and Balham
Earlsfield | SW18 Magdalen Road, Garratt Lane environs
Putney | SW15 Upper Richmond Road, Putney Heath
Southfields | SW18 parts of Replingham Road
Check Planning Permission before adding any new external openings that form part of a bathroom project.
How long does a bathroom renovation take in Wandsworth?
Works on site for a standard bathroom renovation take 1-2 weeks for a basic refit and 2-4 weeks for a full mid-range renovation. A high-specification wet room or en-suite creation takes longer:

2. Sanitaryware and tiles ordered: 1- 4 weeks lead time (longer for bespoke or large-format tiles: 4-8 weeks)
3. Strip-out: 1- 2 days
4. First fix plumbing: 1- 3 days
5. Waterproofing (wet room tanking): 1- 2 days plus drying time
6. Tiling: 2-5 days depending on scope and format
7. First fix electrical: 1 day
8. Sanitaryware installation: 1- 2 days

How do I find a vetted bathroom renovation specialist in Wandsworth?
Bathroom renovation quotes in Wandsworth vary significantly; quotes for the same scope regularly differ by £4,000-£8,000. The difference is usually inclusions: one builder prices supply and fit together, another prices labour only and expects you to supply sanitaryware separately.
To get comparable quotes:
1. Decide on scope before approaching builders: basic refit, full renovation, wet room, or en-suite
2. Select your sanitaryware and tiles before requesting quotes; quotes without specified products are not comparable
3. Ask builders to break down labour, materials, tiles, sanitaryware, plumbing, and electrical separately
4. Confirm whether VAT is included
5. Ask specifically whether the quote includes waterproofing (tanking), underfloor heating matting, and tile adhesive and grout
6. Check that each builder has recent, verifiable bathroom renovation projects in Wandsworth or adjacent south London boroughs
