Bathroom Renovation Wapping

GS Renovation creates bathrooms, en-suites and wet rooms throughout Wapping, working in warehouse-conversion flats and new-build riverside apartments across E1W. We deliver fully waterproofed, beautifully finished bathrooms, managing the tanking, drainage, ventilation, tiling and heating so nothing is left to chance in a flat above other homes.

In Wapping, 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 Wapping: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Wapping home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Waterproofing bathrooms in Wapping flats

In a flat above other homes, watertight waterproofing is not optional, it is essential. Before a single tile goes on, we tank the walls and floor of every Wapping bathroom and wet room, so no moisture reaches the flat below or the building structure. This matters especially in older warehouse conversions, where floors may be timber and a leak could damage a neighbour's ceiling and strain relations across the block.

Drainage and ventilation take real planning in a converted or purpose-built flat, where waste often has to run to fixed soil stacks and extraction to existing routes. We set falls correctly, upgrade ventilation to prevent damp and condensation, and install underfloor heating and heated rails for comfort. No planning permission is needed inside your flat, but new electrics are certified by a registered electrician under Part P and the freeholder's consent is arranged first.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Tower Hamlets Council, and doing it without consent is a criminal offence.

Housing in Wapping

Take the 8,650 or so homes the valuation list gives Wapping: 91% flats, 9% houses, 13% from before 1919, 8% interwar and 79% post-war. Where most homes are flats, a bathroom in a flat in Wapping sits over a neighbour's ceiling, so tanking comes first.

Adding an en-suite to a Wapping flat and the approval route

Replacing a bathroom like for like in Wapping is usually outside building control. Adding an en-suite is not, because it brings new waste pipes to the soil stack, new extraction and new circuits, and Tower Hamlets Council's building control service is responsible for ensuring that building work in the borough complies with building regulations. With 91% of Wapping homes being flats, the new waste run has to reach a stack shared with the homes above and below, so its route and fall are drawn before a bedroom corner is given up.

The council states that the total building control charge is the same whether you deposit full plans or give a building notice. For an en-suite in a Wapping block full plans often makes sense, because the managing agent can check the approved drainage and ventilation drawings before granting the licence to alter. The electrics are separate: a registered electrician certifies the shower and fan circuits, which keeps them outside the building control fee. We gather both certificates at the end so they are ready when the flat is sold.

En-suites and wet rooms in Wapping

Space is often tight in Wapping flats, so we design clever, space-saving layouts, walk-in showers, wall-hung basins and concealed cisterns that make a compact bathroom feel larger. Where a bedroom can spare a corner, we add an en-suite, threading the drainage and ventilation back to existing services. In a generous warehouse conversion with volume to spare, an open wet room can become a genuine feature of the home.

Sound and waterproofing between flats guide every decision, so we isolate pipework to reduce noise and tank thoroughly to protect the homes around you. We tile to a high standard, from large-format porcelain to mosaic detailing, and finish with considered lighting and heating. Throughout, we work to the building's management rules and keep communal areas clean, delivering an E1W bathroom that performs well and looks the part for years.
