Bathroom Remodelling Wandsworth: Victorian Terrace and Mansion Block Specialists From £8,000
✓ Gas Safe Registered | ✓ NICEIC Approved | ✓ All Trades In House | ✓ Fixed Price | ✓ Free Site Visit | ✓ 26 Reviews – 5.0 Stars
A homeowner on Bellevue Road called us in April. Her first-floor bathroom had been quoted three times. The first quote was £6,200 for the bathroom fitter only, with no plumbing and no electrics listed in the scope. The second was £9,800, excluding fixtures entirely. The third was £14,500 all-inclusive, but every trade was subcontracted separately, with three different companies to coordinate.
We visited on a Thursday. We assessed the existing bathroom: an original cast-iron soil pipe running through the floor void, an uneven substrate typical of a Wandsworth Victorian terrace, and lime plaster walls behind the tiles. Confirmed the scope. Delivered a fixed price by Friday: £11,400 including Gas Safe plumbing, NICEIC Part P electrics, waterproofing, tiling, all fixtures, and a 12-month workmanship guarantee.
One team. One invoice. Eleven working days. She did not need to coordinate three separate companies. She did not receive an invoice that differed from the quotation. She hasn’t called us since because there’s been nothing to call about.

Bathroom remodelling in a Wandsworth Victorian terrace, Edwardian semi, or mansion block conversion is not the same job as a modern new-build bathroom. The property types that fill the streets between Wandsworth Common and Battersea the bay-fronted terraces of the Tonsleys, the grid of the Toast Rack, the mansion conversions along Garratt Lane all present the same four specific challenges that a bathroom remodelling company without period property experience will discover after the price has been agreed.
Cast iron and lead pipework
Victorian and Edwardian terraces across SW18 were plumbed with cast iron soil pipes and lead supply pipes. Both require assessment before any bathroom remodelling begins. Cast iron soil pipes are typically sound but may have corroded collar joints. Lead supply pipes are typically functional but are increasingly replaced at the point of bathroom remodelling, a one-off cost that eliminates a long-term maintenance liability. Our Gas Safe engineers assess and replace where required, within the fixed price.
Uneven substrates and solid walls
Wandsworth Victorian terraces have solid masonry walls and suspended timber floors. Neither is flat. Neither is consistent. Tiling directly onto an uneven substrate produces cracked tiles within eighteen months. The correct approach is backer board on walls and levelling compound on floors before any waterproofing or tiling begins. This adds time. It also means the tiles are still intact in seven years.
Wandsworth's 40+ conservation areas
andsworth has more than 40 designated conservation areas, including Wandsworth Town, Earlsfield, and Tonsley. Most internal bathroom remodelling work does not require planning permission regardless of conservation area designation, but external extraction ducting on a principal elevation in a conservation area requires consideration. We confirm the planning position at the free site visit before any work is quoted.
Leasehold and mansion block requirements
A significant proportion of Wandsworth bathroom remodelling projects are in leasehold flats and mansion block conversions. Connections to shared soil stacks, penetrations of concrete floors, and any works affecting the building fabric typically require management company notification or consent. We manage the consent application as part of the fixed price, not as an additional cost discovered after contract signature.

Victorian terraces SW18: The Tonsleys, the Toast Rack, Garratt Lane
Bay-fronted Victorian terraces built 1880s-1910s dominate the streets between Wandsworth Common and Earlsfield. Original cast iron soil pipes. Suspended timber floors. Solid masonry walls. Lime plaster substrate. These are the properties that require backer board and levelling before tiling, substrate assessment before waterproofing, and cast iron pipe assessment before plumbing reconfiguration. Every one of our Wandsworth bathroom remodelling engineers has worked in these properties every week for years. There is no period property discovery at the point of demolition.
Edwardian semis along West Hill and Nightingale Lane
Similar construction to the Victorian terraces, with some variations: slightly wider floor plans, different soil stack positions, occasional concrete floors in rear extensions added in the 1960s and 1970s. Concrete floors simplify wetroom drainage but require diamond cutting for new waste penetrations managed within the fixed price.
Mansion block conversions Battersea SW11 and Balham SW12
Converted Victorian mansion blocks account for a significant proportion of Wandsworth bathroom remodelling work. Concrete floor slabs, shared soil stacks requiring management company consent for new connections, noise restrictions during working hours. Above-slab drainage solutions: macerator pump systems available where floor slab penetration is not possible. From £8,500 including macerator unit.
Loft conversions across SW18
Wandsworth loft conversion en suites are increasingly specified as part of a full loft conversion programme. Soil stack extension to the loft level, pressure management, low-profile shower tray where ceiling height is limited, NICEIC Part P electrics, extraction to roof level. From £9,000.
New-build and purpose-built flats
Standard concrete frame construction. Simpler drainage and substrate. Faster installation. From £8,000 complete.

Bath remodel near me searches in Wandsworth SW18 return contractors based across London, many of them 45 minutes to an hour from the properties they are quoting. The time between a survey call and an engineer arriving matters at two specific points in a bathroom remodelling project.
The first is the survey itself. A contractor travelling from North London to survey a bathroom in SW18 will spend less time at the property. The assessment of the soil stack position, the substrate condition, the conservation area position, and the management company requirements will be cursory. The price will reflect what they can see in twenty minutes, not what is behind the tiles.
The second is during the project. When something unexpected emerges during strip-out corroded cast iron pipework, a soil stack position that does not match the survey, a concrete floor where a timber floor was expected the response time of an engineer from the same base determines whether the project loses half a day or three days.
Chelsea Property Renovation & Maintenance Ltd is based at 289 Brompton Road, Knightsbridge SW3. Wandsworth SW18 is 20 minutes from our base. Our engineers are in Wandsworth and the surrounding SW postcodes every week: SW11 Battersea, SW12 Balham, SW17 Tooting, SW19 Wimbledon, SW15 Putney. The survey is thorough because the engineer has time. The project response is fast because the base is close.

Bathroom remodel cost Wandsworth: The honest figures for 2026
Bathroom remodel cost in Wandsworth SW18 varies significantly depending on three factors: scope, specification, and the property type. The figures below are confirmed ranges for 2026 based on our completed projects across SW18 and the surrounding postcodes.
What drives bathroom remodel cost in Wandsworth up

Small Bathroom Remodelling - What is possible in a compact space
The most common concern before a small bathroom remodelling project in Wandsworth is whether the result will justify the cost. A bathroom under 4 square metres feels like it has limited potential. It does not.
The Wandsworth Victorian terrace small bathroom is typically the first-floor bathroom in the original house plan, 2.5 to 4 square metres, with one sash window, original cast iron soil pipe in the corner, and can be transformed significantly within its existing footprint. The key is space planning at the site visit stage, before a single price is quoted.
Three decisions made at the space planning stage determine everything. The first is whether the bath stays or goes. Removing the bath and installing a walk-in shower enclosure or a wet room recovers between 0.6 and 1.2 square metres of floor space, a significant proportion of a small bathroom. The second is whether the WC can move. Repositioning the WC by 300- 400 mm sometimes allows a vanity unit with storage to be added where none was possible before. The third is whether the door opens inward. An inward-opening door in a small bathroom loses usable space every time it opens; converting to an outward-opening or sliding door adds floor area for no structural cost.
Small Bathroom Remodelling Wandsworth confirmed prices:
Bath to shower conversion from £4,500. Walk-in shower enclosure installed in existing bathroom footprint from £2,500. Compact wetroom from £6,500. Full small bathroom remodelling: new layout, new suite, full retile, Gas Safe plumbing, NICEIC electrics, all in-house, from £6,500. Standard bathroom remodelling from £8,000.
Free site visit includes space planning and the most efficient layout, confirmed before any price is quoted. Fixed price within 48 hours. All prices exclude VAT. Call 020 7129 7418.
Shower Room Renovation Wandsworth: Dedicated shower room and wet room specialists
A shower room renovation in Wandsworth is a different project from a full bathroom renovation and a different price. A dedicated shower room contains a shower enclosure or wet room, a basin, a WC, and no bath. It is the correct specification for a second bathroom in a Wandsworth Victorian terrace, a loft conversion en suite, or a principal bathroom where the bath has not been used in years.
The specific challenge of a shower room renovation in a Wandsworth Victorian terrace is the floor structure. A walk-in wetroom requires a linear drain set into the floor at the correct fall. In a modern property with a concrete floor, this is straightforward. In a Victorian terrace with suspended timber joists, it requires an assessment of joist depth and direction relative to the proposed drain position before the layout is designed. If the joists run parallel to the proposed drain and the depth is sufficient, a conventional wetroom drain can be set into the floor. If not, two solutions are available: a raised platform wetroom with the drain within the platform, or a linear drain positioned at the wall junction where it can connect above the floor structure.
We assess the floor structure at the free site visit. The layout is designed around what the floor will support. The price is fixed before any work begins.
Shower Room Renovation Wandsworth Confirmed Prices:
Dedicated shower room new layout, walk-in enclosure, basin, WC, full retile, Gas Safe, NICEIC, all in-house: from £6,500.
Walk-in wet room: linear drain, full tanking, full retile, Gas Safe, NICEIC: from £9,500.
Bath to shower conversion: bath removed, walk-in shower installed, waterproofing and retile: from £4,500.
Shower enclosure installed within existing bathroom: from £2,500.
Gas Safe underfloor heating added to any shower room renovation: from £800.
