Luxury bathroom and wet-room refurbishment in Bromley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms across Bromley, from family bathrooms in interwar BR1 semis to compact en-suites carved out of period homes in Chislehurst and Beckenham. With over 30 years in the borough, we handle the waterproofing, drainage, tiling, heating and ventilation as one job, so your new bathroom is built to last and properly protected against leaks.

A walk-in shower or full wet room is a popular upgrade in Bromley's interwar houses, but it only works when the waterproofing is done properly. We tank the walls and floor before a single tile goes on, forming falls to the drainage so water runs away cleanly rather than pooling. Skipping this step is the usual cause of the damp and staining we are so often called in to put right in older BR-postcode homes.
In a 1930s semi in BR5 or BR6 the original bathroom is often small, so we plan the layout carefully to fit a generous shower, the sanitaryware and storage without it feeling cramped. We upgrade the drainage and extraction at the same time, because a well-ventilated bathroom stays free of condensation and mould, and we finish with tiling and heating designed to work together.
Interwar Bromley houses rarely came with en-suites, so we create them from the corner of a bedroom or an oversized landing, adding a bathroom near where the family sleeps without losing a whole room. We run the new drainage back to the existing soil stack, which needs planning around the layout of a 1930s semi, and we soundproof and ventilate the space so it works well within the house.
Underfloor heating suits these projects, freeing wall space in a tight en-suite and warming tiled floors that would otherwise feel cold. In period homes near Beckenham Place Park or Chislehurst Common we design space-saving layouts that use every inch, wall-hung basins, recessed shelving and slim shower enclosures, so a small footprint in BR3 or BR7 still delivers a proper, comfortable bathroom.
Bromley homeowners choose GS Renovation because we get the hidden work right, the tanking, the falls, the drainage and the ventilation, before any tiling begins. One team handles the plumbing, electrics, heating and finish, so there is no gap for leaks to appear later. With 30+ years across BR1 to BR7 and SE20, we build bathrooms that stay watertight.

FAQ
Usually because they are not quoting the same work. One builder includes making good and the Bromley Council application, another leaves both out, and the bathroom renovation figures for the same Bromley house then look nothing alike. GS Renovation itemises every line for the BR1 property so you can see what is in and what is missing. Compare the scope before the totals, and ring 07472 424 226 if another Bromley quotation for bathroom renovation puzzles you. 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.
Yes. The team on your bathroom renovation project stays on it until the BR1 work is finished, which is the whole reason the Bromley programme is predictable. GS Renovation does not open several Bromley sites and rotate between them, and that is the commonest complaint homeowners have about builders. One named project manager sees the job through to sign-off. Ask for Bromley references and check how a BR1 project actually ran in Bromley.
Because you get one accountable team rather than a chain of subcontractors. GS Renovation is the contractor carrying out bathroom renovation at your BR1 property, with a named project manager from survey to handover and full insurance throughout. We are rated 4.9 from 31 reviews on MyBuilder, and the Bromley Council paperwork is handled for you. That applies across Bromley and the wider Bromley. Ring 07472 424 226 and ask for BR1 references. Insurance details follow on info@gsrenovationltd.co.uk request.
Yes. Bathroom electrics in Bromley 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 Bromley Council building control on every BR1 bathroom.
Sometimes, depending on where the property sits. Bathroom renovation in 1930s semi-detached and interwar suburban houses on generous plots within a conservation area is usually possible but more constrained in form, and Bromley Council will scrutinise anything visible from the street at BR1. GS Renovation handles the application and the negotiation. Internal work in a Bromley house is generally more straightforward. Ring 07472 424 226 and we will explain what Bromley Council is likely to ask about bathroom renovation at a BR1 address of that age.
Adding an en-suite inside your Bromley home does not need planning permission, as you are not changing the exterior. It is building regulations work, and the new electrics and any drainage changes must meet those standards, with notifiable electrical work certified. The most important part is proper tanking and ventilation. We handle the drainage, waterproofing and sign-off so your new en-suite is safe and watertight.
Not within our normal patch, and Bromley is comfortably inside it. The bathroom renovation quotation for your BR1 home covers labour, materials, approvals and making good, with no line for mileage.
