Bathroom Renovation Woolwich

GS Renovation renovates bathrooms throughout Woolwich, in the post-war flats that make up most of its homes and in its Victorian terraces. We deliver full waterproofing, tiling, drainage, ventilation and heating, from compact family bathrooms to walk-in wet rooms and neat en-suites.

In Woolwich, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Woolwich: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

Wet rooms and waterproofing in Woolwich

Proper waterproofing is the part of a bathroom that never shows but matters most. Before any tiling goes on, we tank the walls and floor so water cannot reach the timber structure behind, which is especially important in the older suspended floors and solid walls of Woolwich terraces. For a walk-in shower or full wet room we form the falls correctly, bond the tanking to the drainage, and make sure the whole area sheds water to the outlet.

Drainage and ventilation are just as important as the finish. In Woolwich's terraces many bathrooms sit in the original closet wing, and in its flats they are tied to a shared stack, so we plan the soil and waste routes carefully and upgrade extraction to keep condensation and mould at bay. Underfloor heating warms the floor and helps the room dry quickly, and we finish the tiling to a standard that lasts.

Housing in Woolwich

The valuation list shows roughly 21,990 homes in Woolwich, of which 24% are pre-1919, 2% interwar and 75% post-1945, split 74% flats to 26% houses. Where most homes are flats, a bathroom in a flat in Woolwich sits over a neighbour's ceiling, so tanking comes first.

A shower room in a Woolwich cellar and the flood rules

In Woolwich 24% of homes were built before 1919, and an older terrace can have a cellar an owner wants to turn into a shower room or utility space. Royal Greenwich will not permit basements in flood zone 3, and will not normally permit them in flood zone 2 unless no habitable rooms are proposed. Woolwich sits on the river, so look up the address on the Environment Agency flood map before paying for any design. A shower room and store is a different proposal from a bedroom below ground.

Where the cellar adjoins another home, becomes habitable accommodation and needs planning permission, Royal Greenwich requires a Basement Impact Assessment. Even a modest bathroom conversion raises two practical questions. The first is how the waste reaches the sewer, since a cellar floor can sit below the drain and need a pumped outlet. The second is tanking, which in a Woolwich cellar is a structural waterproofing design, not the tanking that goes under tiles. Settle both before the bathroom layout is drawn.

Space-saving en-suites in SE18 period homes

Victorian and Edwardian terraces in Woolwich were not designed with modern bathrooms in mind, so making the most of tight space is part of the craft. We design compact layouts that fit a shower, basin and WC into a small footprint, use wall-hung fittings to free up floor area, and reconfigure the awkward corners of the closet wing to work harder. Good lighting and the right tile scale make a small SE18 bathroom feel far larger.

Adding an en-suite to a main bedroom is a popular upgrade in these homes, borrowing space from an oversized room or a landing. We handle the new drainage, plumbing and ventilation, and where a stud wall or minor structural change is involved we build it properly. New circuits and changes around the bath or shower are notifiable, so they are certified by a registered electrician under Part P, or notified to building control, leaving you a safe, watertight and comfortable room.
