Luxury bathroom and wet-room refurbishment in Eltham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Eltham, working within the layouts of 1930s semi-detached and interwar houses where space is often tight upstairs. With over 30 years of experience in SE9 and the Royal Borough of Greenwich, we deliver fully waterproofed, well-drained bathrooms and en-suites finished to a lasting standard.

A bathroom that lasts starts with proper waterproofing. Before any tile goes on, we tank the walls and floor in wet areas so moisture cannot track into the structure of an older SE9 house. For walk-in showers and full wet rooms we install the correct falls, drainage and a sealed substrate, which matters in interwar homes where original floors are not always level and hidden leaks can rot timbers over time.
Ventilation is just as important as tanking. Eltham bathrooms in these houses can suffer from condensation and damp if extraction is poor, so we fit properly rated extractor fans and, where needed, improve the airflow. Add underfloor heating, quality tiling and good lighting, and the room stays warm, dry and free of the mould that plagues neglected bathrooms in period property.
Interwar Eltham houses often have a generous main bedroom that can give up a corner for an en-suite, or a boxroom that suits a compact shower room. We plan the layout carefully around existing soil pipes and joists, since moving drainage in these homes takes thought rather than guesswork. Careful positioning of the WC, basin and shower makes even a small space feel usable rather than cramped.
In the family bathroom, small changes to the layout can free up real room, such as swapping a bulky bath for a walk-in shower or repositioning the basin to open the floor. Bathroom electrics are notifiable under building regulations, so we certify new circuits and zoned lighting correctly. The result is a bathroom that fits the proportions of a 1930s SE9 house and works for a busy household.
Eltham homeowners choose GS Renovation because a bathroom is only as good as its waterproofing and drainage, which is easy to get wrong in an older SE9 house. We tank properly, sort ventilation, plan around existing soil pipes and certify notifiable electrics. With 30+ years across the Royal Borough of Greenwich, we deliver en-suites and family bathrooms built to stay dry and warm.

FAQ
Because scope, not skill, is what differs. A bathroom renovation quotation that omits the engineer, the Royal Borough of Greenwich fee or the making good will always undercut one that includes them, which is why Eltham homeowners see such a spread. We list each element for the SE9 address so nothing hides. GS Renovation would rather explain a difference than quietly match a lower Greenwich figure. Ask every Greenwich builder quoting for your SE9 home to supply the same breakdown. 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.
Fewer at once than you might expect, by design. Stacking trades into an SE9 property makes a bathroom renovation job feel busy while achieving very little, so GS Renovation sequences them and keeps the Eltham site workable. You always know who is due and when. The programme issued with the Greenwich quotation names each stage and each week. The Eltham programme names who is coming to the SE9 property in each Greenwich week.
References, reviews and finished addresses are all available on request. GS Renovation has carried out bathroom renovation across Eltham and Greenwich, and the SE9 area in particular, so there is usually something nearby to look at. Email info@gsrenovationltd.co.uk and we will send details. Checking a contractor properly before committing is time well spent, in South East London as anywhere else. Ring 07472 424 226 and we will point you at recently finished SE9 work in Eltham.
Usually yes, and it is one of the commonest upgrades we make in Eltham. The constraints are the soil stack route and the floor structure, both checked at survey, and the electrics need Part P certification through Royal Borough of Greenwich.
Yes, constantly. A large share of the housing around SE9 is exactly that, and bathroom renovation in it is planned around how those buildings were put together rather than adapted halfway through. GS Renovation surveys each Eltham property before committing to a method or a price. The same applies across Greenwich and over in Woolwich. Ring 07472 424 226 and we will describe how bathroom renovation usually runs in an SE9 house of that age in Eltham.
Often yes. The generous main bedrooms in Eltham's interwar houses can usually spare a corner for an en-suite. The key is planning the layout around existing soil pipes and joists so drainage runs correctly. We tank the wet areas, fit proper ventilation and underfloor heating, and certify the notifiable electrics, giving you a compact, fully waterproofed shower room that fits the house.
We do not think of it as travelling, because Eltham is inside our normal working area. Bathroom renovation projects run across Greenwich most weeks, so reaching an SE9 address is routine and there is no surcharge for it. GS Renovation also returns for aftercare, which matters more than the initial journey. Ring 07472 424 226 and we will confirm the position. The survey costs an Eltham homeowner nothing. Snagging visits to SE9 are equally routine.
