Bathroom Renovation Putney

GS Renovation renovates bathrooms and en-suites across Putney, from compact shower rooms in SW15 flats, the majority of its homes, to family bathrooms in Victorian terraces. We get the waterproofing, drainage and ventilation right beneath the tiling, so a new bathroom stays sound for years rather than months.

In Putney, 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 Putney: 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 Putney 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 Putney period homes

In a Putney period home, terrace or converted flat, the bathroom often sits over a suspended timber floor or within the rear closet wing, where movement and moisture are the real enemies. Before any tile goes on, we tank the wet areas properly, bonding a waterproof membrane to walls and floor so water cannot track into the joists below. For a wet room or walk-in shower we form the falls, set the drainage and lay the tanking as one tested system.

Getting the services right is just as important as the surface. We upgrade drainage runs and soil connections where the original pipework is undersized, and we fit proper mechanical ventilation to clear the humidity that rots period bathrooms. Any new electrics, from the shower circuit to heated towel rails, are installed and certified by a registered electrician under Part P, so the whole room is safe as well as watertight.

Housing in Putney

The valuation list shows roughly 20,990 homes in Putney, of which 36% are pre-1919, 8% interwar and 54% post-1945, split 75% flats to 25% houses. Where most homes are flats, a bathroom in a flat in Putney sits over a neighbour's ceiling, so tanking comes first.

A new Putney bathroom layout and the building notice route

Swapping the fittings in a Putney bathroom is not usually building control work. Moving them can be, because a new connection to the soil stack and a new extract duct are controlled work, and electrical work near the bath or shower is notifiable through a registered electrician. With 75% of Putney's homes being flats, that stack is often shared and the connection is a lease matter too. Where a building notice is the route, Wandsworth lets you start on site 48 hours after the notice is submitted, provided the correct fee has been paid. Confirm with Wandsworth Building Control that the route is open for your building first, since a building notice cannot be used for every type of building.

The catch is payment. For a building notice application in Wandsworth the whole fee is due when the application is made, and the application is invalid until the council receives payment. A notice sent with the fee still to follow does not start the 48 hours. So the fee goes with the notice, and the start date for a Putney bathroom is set from the day it is paid, not the day the form was emailed. Keep the waste run and the tanking open until the inspector has seen them, and book the tiler for after that visit.

Space-saving en-suites for SW15 homes

Space is tight in Putney's flats and terraces, so we are used to finding a shower room or en-suite where there seems to be none, over the stairs, off a rear bedroom or within the closet wing return. Clever layout does most of the work: a walk-in shower instead of a bath, a wall-hung basin and toilet to free the floor, and a sliding or outward door where a normal one would foul the fittings. Underfloor heating keeps the walls clear of radiators.

We match the specification to the room and the house. In a period Putney home that might mean traditional sanitaryware and metro tiling; in a modern refit, large-format porcelain and concealed cisterns. Whatever the style, the tiling, grouting and sealant details are finished to last, the ventilation is sized for the space, and the plumbing is planned so a small en-suite performs like a full bathroom.

• Wall and floor tiling in stone, porcelain or mosaic
• Ventilation and extraction ducted to outside
• Downstairs cloakroom and WC installation
