Luxury bathroom and wet-room refurbishment in Borough. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Borough and SE1, making the most of the compact spaces found in Southwark's Victorian and Edwardian terraces. With over 30 years of experience, we handle waterproofing, drainage, tiling and heating as one job, on homes from near the South Bank to the terraces stretching towards Dulwich.

Bathrooms in Borough terraces are often tucked into the rear closet wing or carved from a small upstairs room, so clever layout matters more than anything. We plan walk-in showers, wall-hung basins and concealed cisterns to free up floor space, and we can create a compact en-suite off a main bedroom where the plumbing allows. Working within the tight dimensions of these SE1 homes is exactly the sort of problem we solve every week.
Getting the services right in a period terrace takes care. We reroute or upgrade the drainage, which in these older houses is not always where you would want it, and we add proper mechanical ventilation to protect the solid walls from damp. Underfloor heating is a popular addition, warming the room and removing the need for a bulky radiator in a bathroom where every centimetre counts.
Reliable waterproofing is the foundation of any bathroom we build in Borough. Before a single tile goes on, we tank the wet areas thoroughly, sealing the substrate so water cannot reach the timber floors and solid walls behind. This matters especially in a wet room, where the whole floor drains, and it protects both your home and the neighbours below in these closely built terraces.
Once the room is properly tanked we tile to a high standard, fit the shower, sanitaryware and heating, and finish the ventilation and lighting. The bathroom electrics are notified under building regulations, which we arrange for you. Whether you want a full wet room, a walk-in shower or a family bathroom that suits the character of your Victorian or Edwardian home, we deliver it watertight and built to last.
Borough homeowners choose GS Renovation because we handle the bathroom completely, from tanking and drainage to tiling, heating and ventilation, with the electrics notified for you. Three decades on SE1 terraces means we know how to waterproof solid-wall homes and how to fit real comfort into the compact spaces these Victorian and Edwardian houses provide.

FAQ
It covers the whole job through to sign-off. The document lists the structural work, the trades that follow, the Southwark Council inspections and the making good at the SE1 property, with the engineer's fee shown where bathroom renovation needs a design. Site protection and the daily clear-up are included. GS Renovation issues it in writing so a Borough homeowner has something to hold us to. Ring 07472 424 226 for a sample Southwark layout before the SE1 survey. 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.
Longer than the fastest quote you will be given, and shorter than an open-ended one. GS Renovation would rather set bathroom renovation dates a Borough homeowner can plan around than win the SE1 job on a programme nobody can meet. The stages, the trades and the Southwark Council points are all written down. You are updated against them weekly throughout the Southwark project. Ring 07472 424 226 and we will describe how a comparable SE1 project ran.
Our founder has spent over 30 years on the tools, and that experience is what a Borough homeowner is buying. Bathroom renovation at an SE1 address is run by one named manager, fully insured, with the Southwark Council approvals coordinated rather than left with you. Installations carry a five year guarantee. Quotes are free and there is no obligation. Email info@gsrenovationltd.co.uk and we will arrange a Southwark survey. The Borough certificate is available before any Southwark work starts.
Not for internal work. Converting a bedroom to a bathroom in a Borough house is an internal alteration, so planning is not engaged, though building regulations are. External changes such as a new soil vent pipe on an SE1 property may need permission in a conservation area.
We do, week in and week out. Solid-wall Victorian terraces with original chimney breasts and suspended timber floors make up much of Borough, so bathroom renovation on them is core work for GS Renovation rather than an occasional job. The SE1 survey establishes what is actually there before anything structural is touched. Southwark Council building control is coordinated by us in the usual way. Ask on 07472 424 226 what an SE1 property of that age typically needs before bathroom renovation can even begin in Borough.
Yes. In Borough terraces we regularly turn compact bathrooms, often in the rear closet wing, into walk-in wet rooms. The key is thorough tanking so water cannot reach the timber and solid walls, plus proper drainage and ventilation. We handle the waterproofing, tiling, heating and the notifiable electrics, delivering a watertight room that makes the most of a tight SE1 space.
No minimum. GS Renovation takes small bathroom renovation work at an SE1 property as readily as a full project, and a modest job is how many of our larger Borough contracts began. The survey is free either way. Ring 07472 424 226 and describe what you have in mind for your Southwark home. We will say honestly if another trade suits you better. The SE1 survey is free whether the Southwark job is large or small.
