Luxury bathroom and wet-room refurbishment in Barnet. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms across Barnet, from compact family bathrooms in 1930s Finchley semis to en-suites in the larger interwar homes of Mill Hill and Hendon. With over 30 years across N3, N12, NW4 and NW7, we handle waterproofing, drainage, tiling and heating, delivering wet rooms and bathrooms built to last.

Proper waterproofing is what separates a bathroom that lasts from one that fails. In Barnet's interwar homes we tank and seal wet areas fully before tiling, whether we are fitting a straightforward family bathroom or a level-access wet room. Walk-in showers are increasingly popular across Finchley and Edgware, and they need the floor falls, membranes and drainage detailed correctly from the outset to stay watertight for years.
Behind the tiles we sort the parts that matter, reliable hot and cold supplies, well-graded waste runs and adequate ventilation to manage the condensation these older houses are prone to. Underfloor heating warms the room and speeds drying, a real benefit in solid-floor bathrooms. All bathroom electrics are installed to current standards and notified under building regulations, so the finished room is safe as well as good-looking.
The bathrooms in Barnet's 1930s semis are often tight, tucked over the stairs or squeezed beside a chimney breast, so a clever layout matters. We plan sanitaryware, storage and screens to make the most of every inch, whether we are updating the family bathroom or carving an en-suite out of a box room or loft conversion. Concealed cisterns and wall-hung fittings free up valuable floor space.
Finish is where these rooms come alive. We tile fully to the waterproofed substrate, fit quality brassware and sanitaryware, and add the heating, lighting and extraction that make a bathroom comfortable year-round. From a compact en-suite in a Golders Green semi to a spa-style family bathroom near Hampstead Garden Suburb, the plumbing, tiling and electrics are all handled by our own team.
Homeowners across Barnet choose us for bathrooms because we get the hidden work right, the tanking, drainage and ventilation, not just the tiles on top. Thirty-plus years in the borough's interwar homes means we know how these houses behave. One team handles plumbing, tiling, heating and notified electrics for a watertight, lasting result.

FAQ
Sometimes, though rarely by as much as people fear. The structural part of bathroom renovation is broadly similar; what differs in a 1930s and interwar Barnet house is reinstating cornice, floors and plaster around the EN4 works. Those appear as separate lines on the quotation. GS Renovation has worked on this stock for years and prices it from experience rather than caution. Ring 07472 424 226 and we will describe recent work on similar EN4 properties in Barnet. 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.
You hear it from us first, with the reason and the revised dates. If bathroom renovation at your EN4 property runs beyond the programme, GS Renovation explains whether the cause is a discovery in a 1930s and interwar structure, a Barnet Council inspection slot or something of ours. Fixed-price work does not become more expensive because it took longer. The Barnet updates continue weekly regardless. Ring 07472 424 226 and GS Renovation will explain how an EN4 overrun is handled.
Yes, fully insured, and we will show you the certificate before work starts. GS Renovation carries cover for every bathroom renovation project, whether the property is in Barnet or over in Enfield, and we are GS Renovation Ltd, company number 14611254. You can check that independently. Ask any contractor quoting for your EN4 home to evidence the same. Email info@gsrenovationltd.co.uk and we will send ours for Barnet work. The certificate is offered before any EN4 work starts.
Yes. Bathroom electrics in Barnet are notifiable under Part P and must be certified, and drainage, ventilation and any structural change must meet building regulations. GS Renovation includes certified electrical work and manages Barnet Council building control on every EN4 bathroom.
Mostly by removing the guesswork a modern house allows. GS Renovation cannot assume how a 1930s and interwar EN4 property is built, so bathroom renovation starts with confirming it and the quotation follows from there. That is slower at the start and far more reliable afterwards. Homeowners right across Barnet and Barnet get exactly the same approach. Ask on 07472 424 226 what bathroom renovation at an EN4 property in Barnet has to establish before any design work.
Usually yes. In Barnet's interwar semis we often create en-suites from part of a large bedroom, a box room or a loft conversion, using space-saving fittings and concealed cisterns to keep it comfortable. The key is getting the drainage, waterproofing and ventilation right, sometimes with a pumped waste where gravity falls are limited. All electrics are notified under building regulations.
Yes, and it shows in the quotation rather than in the marketing. Working on bay-windowed 1930s semis with side access and separate garages around EN4 week after week is what lets GS Renovation price bathroom renovation from experience instead of caution. Being nearby also means returning quickly for aftercare on a Barnet job. Ask for addresses of finished work in Barnet and go and look. Ring 07472 424 226 and we will arrange that. Finished EN4 work nearby is usually available to view.
