Bathroom Renovation Paddington

GS Renovation fits bathrooms, en-suites and wet rooms across Paddington's Victorian townhouses and conversion flats, where awkward proportions and older fabric call for careful work. We handle the waterproofing, drainage, tiling and finish so nothing is left to chance behind the walls.

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

Waterproofing period bathrooms in Paddington

Getting a bathroom right in a Paddington townhouse begins with what you cannot see. Older solid floors, timber joists and lath-and-plaster walls all demand proper tanking before a single tile goes down, particularly for a wet room or a walk-in shower. We fully waterproof the wet zones, upgrade drainage and ventilation to control moisture, and only then move on to the finishes.

Ventilation matters in these homes, where high humidity and original plaster do not mix, so we specify extraction that clears moisture and protects the fabric. Where a new soil or waste connection is needed on an upper floor, we plan the runs carefully within the existing structure. Doing the concealed work correctly is what keeps a period bathroom sound for years to come.

Housing in Paddington

By the valuation list's count, Paddington holds about 11,790 homes, 8% houses and 92% flats; by age, 47% were built before 1919, 11% between the wars and 42% since 1945. Since most homes here are flats, a bathroom in a flat in Paddington sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

Paddington bathroom vents and pipes on a conservation area elevation

The part of a Paddington bathroom refit that reaches the street is the extract terminal and any new waste pipe on the outside wall. Westminster's 56 conservation areas cover over 76% of the City, and the Bayswater conservation area takes in the area around Paddington Station, so there is a real chance a new grille or external pipe is being added to a protected street. In a Westminster conservation area, planning permission is needed for some alterations that would not need permission elsewhere, and a new pipe run on a front elevation is the kind of change worth checking before the layout is fixed.

We route bathroom extraction and waste internally wherever the building allows: through an existing riser, into a lightwell at the back, or along a ceiling void to an elevation that is not on show. Only where that fails do we propose a new terminal on a principal elevation, and then with the planning position settled first. In a converted Paddington townhouse the external walls normally belong to the freeholder, so their written consent is needed for any new hole, whichever elevation it is on, and the lease plan shows who owns what.

Space-saving bathroom layouts in Paddington homes

Period townhouses in W2 rarely offer generous bathroom space, so many of our projects convert a box room, a landing or part of a bedroom into a well-planned en-suite. We design layouts that make the most of tight footprints and awkward angles, using wall-hung sanitaryware, walk-in showers and concealed cisterns to keep the room feeling open despite its size.

Underfloor heating frees the walls of radiators and suits the cold solid floors common in these homes, while good tiling and lighting lift a small space. Notifiable electrical work is certified by a registered electrician under Part P, and in listed properties we confirm what Westminster City Council allows before altering anything of historic interest. The finished bathroom balances comfort, practicality and the character of the house.

The GS Renovation Difference in Paddington

Paddington owners choose GS Renovation because a bathroom in a period townhouse lives or dies on the work behind the tiles. We tank and waterproof properly, sort out drainage and ventilation, and finish to a high standard, all through one team. Our founder's 30+ years on the tools means fewer leaks, fewer callbacks and a bathroom built to last.
