Luxury bathroom and wet-room refurbishment in Croydon. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Croydon, from the 1930s semis of Purley and Coulsdon to the interwar and Victorian homes around Addiscombe and SE19. With over 30 years in CR0, CR2 and CR7, we handle the waterproofing, drainage, tiling, heating and every trade in-house.

A well-built Croydon bathroom starts with what you cannot see. Before any tile goes down we tank and waterproof the floor and the shower zone, so wet rooms and walk-in showers stay dry for the long term rather than failing at the edges. We form the falls to the drainage, set the ventilation to clear moisture and only then tile out, whether that is large-format porcelain or classic metro across the walls.
In the interwar semis common across Purley and Coulsdon we often reconfigure a dated 1930s bathroom into a walk-in shower with underfloor heating and a heated towel rail. Where drainage needs rerouting to suit the new layout, we handle the pipework properly so falls and traps meet building regulations, and the room works reliably every day, not just on the day it is finished.
Many Croydon homeowners want to carve an en-suite out of a bedroom or convert an old box room, and the interwar semis around CR7 and SE25 usually have the space to make it work. We plan the layout to fit a compact shower, basin and WC without cramping the bedroom, then run new hot and cold supplies, waste and ventilation to the new position, coordinating soil connections carefully.
In the older Victorian and period homes near Crystal Palace and SE19, awkward proportions and chimney breasts call for a made-to-measure approach, with fittings chosen to suit the room rather than forced into a standard grid. Underfloor heating, recessed niches and considered lighting all help a smaller Croydon bathroom feel generous. Every element, from first-fix plumbing to the final seal, is delivered by one team.
Croydon homeowners choose GS Renovation because a lasting bathroom depends on the waterproofing, drainage and ventilation being right, not just the tiles. We deliver every stage in-house to one standard, with notifiable electrics certified under building regulations. With 30+ years across CR0, CR2 and CR7, we build wet rooms and en-suites that stay reliable for years.

FAQ
Labour, materials, approvals, reinstatement and the programme. GS Renovation writes the bathroom renovation quotation for your CR0 home so each element can be checked against another builder's, which is impossible when a rival supplies one round number. The Croydon Council element and any engineer's fee are visible. Email info@gsrenovationltd.co.uk to see the layout before the survey. That Croydon survey is free and carries no obligation, at a CR0 address or anywhere else in Croydon. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
It varies by stage, and they are coordinated rather than overlapping. The structural phase of bathroom renovation at a CR0 property is a small team, after which electricians, plumbers, plasterers and decorators follow in sequence through your Croydon home. GS Renovation manages them in-house so nobody waits on anybody. One named project manager runs the Croydon site throughout. Ring 07472 424 226 and GS Renovation will name the trades due at a CR0 property in Croydon.
We are, on every job without exception. Insurance is not something a Croydon homeowner should have to ask about, so the certificate is offered with the bathroom renovation quotation for your CR0 property rather than produced afterwards. GS Renovation also coordinates Croydon Council building control, which is the other protection that matters. Both are included as standard across Croydon. Ring 07472 424 226 if you want the documents first. Company number 14611254 is on every Croydon document.
Not for internal work. Converting a bedroom to a bathroom in a Croydon house is an internal alteration, so planning is not engaged, though building regulations are. External changes such as a new soil vent pipe on a CR0 property may need permission in a conservation area.
Not if the work is planned around them, which is what we do. Cornice, fireplaces, sash windows and original floors at a CR0 property are identified before bathroom renovation begins, and GS Renovation agrees with you which are being retained. Protection goes up before any structural work starts. Reinstatement afterwards is matched rather than approximated in the Croydon house. GS Renovation will explain how bathroom renovation protects original detail at a CR0 address in Croydon.
Yes. The key in a Purley interwar semi is proper tanking and waterproofing under the tiles, with the floor falls set correctly to the drain and good ventilation to clear moisture. We reroute pipework where the new layout needs it, add underfloor heating if you wish, and handle every trade in-house so the finished wet room stays dry and reliable across CR2 and the wider CR postcodes.
Yes, Croydon in its entirety, not just Croydon. Bathroom renovation projects run across the borough most weeks, so a CR0 address is easy for us to reach and to return to for aftercare. GS Renovation coordinates Croydon Council building control throughout. Ring 07472 424 226 and we will confirm availability for your street. The survey that follows is free and carries no obligation. Small jobs and large ones are quoted on the same CR0 basis.
