Bathroom Renovation Purley

GS Renovation renovates bathrooms across Purley, where half the homes are flats and the older houses of CR8, Edwardian villas and interwar semis alike, were built with a single family bathroom and no en-suite. We deliver full waterproofing, wet rooms, walk-in showers and space-saving layouts, handling the drainage, ventilation, tiling and heating from strip-out to final seal.

In Purley, 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 Purley: 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 Purley 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.

Wet rooms and en-suites in Purley homes

Turning a bathroom into a wet room or walk-in shower in a Purley house starts below the surface. We tank and waterproof the floor and walls properly before a single tile goes on, because a failure here shows up as damp in the room below. We set the falls to the drain, upgrade the ventilation to clear moisture, and check the existing drainage can take the new arrangement before we commit to a layout.

The generous size of many interwar Purley homes leaves room to carve an en-suite out of a large bedroom or the landing, something the original 1930s plan never included. We frame the new space, run the drainage and add extraction, then finish with tiling and underfloor heating so a bedroom gains a private bathroom without the rest of the floor feeling cramped.

Housing in Purley

Purley has around 8,800 homes on the Council Tax list: 42% post-war, 24% interwar and 32% predate 1919, with 50% flats and 49% houses. Where many homes are flats, a bathroom in a flat in Purley sits over a neighbour's ceiling, so tanking comes first.

Adding en-suites to a large Purley house

The site describes Purley's housing as post-war flats, large detached houses and interwar semis, and in the larger houses the job may be a second or third bathroom rather than a new family one. Croydon states that building control approval is not needed for refurbishing an existing bathroom or toilet, but installing a new bathroom is one of the minor works a building notice is aimed at. An en-suite carved out of a bedroom is new, so it goes on a notice.

In a big Purley house the difficulty is distance. An en-suite at the far end of a long first floor may be a long way from the soil stack, and the waste has to keep a steady fall all the way. Run it between the joists where they point the right way, add a new stack on an outside wall, or accept a pump as a last resort. Settle the route before the stud walls go up, because it decides where the shower tray can sit.

Space-saving bathrooms in interwar CR8 houses

Where the original bathroom is tight, we plan every centimetre, using wall-hung sanitaryware, recessed shelving in the stud walls and clever door swings to make a small Purley bathroom feel larger. Underfloor heating frees the walls of a radiator, and good lighting and extraction keep a north-facing interwar bathroom bright and free of condensation.

All the notifiable electrical work is certified by a registered electrician under Part P, or notified to building control, and we choose tiling and fittings that suit the age of the house without feeling dated. Because we handle the plumbing, the tiling, the heating and the decoration ourselves, the job runs to one schedule and one standard, and your CR8 bathroom is back in use as quickly as a thorough waterproofing programme allows.
