Luxury bathroom and wet-room refurbishment in Pinner. Trusted, professional, 30+ years' hands-on experience.
For over 30 years GS Renovation has renovated bathrooms across Pinner, in the bay-fronted Victorian and Edwardian terraces, period cottages and interwar semis of HA5. From a compact family bathroom to a tanked wet room or a loft en-suite, we handle the drainage, waterproofing, tiling, heating and ventilation as one job, so the room is watertight and built to last.

Pinner's period homes rarely came with the bathrooms modern families want, so we often carve an en-suite out of a bedroom or turn the old rear closet-wing bathroom into a walk-in shower room. The key is getting the waterproofing right, we fully tank the walls and floor before tiling, then form proper falls to the drainage so water goes where it should. On solid timber floors we reinforce and level the deck so tiles do not crack or lift later.
Ventilation matters just as much in these older, less breathable houses. We fit adequate extraction to clear moisture and protect the plaster and timbers, and run new soil and waste connections to suit the existing drainage. Underfloor heating under tiled floors is a popular addition, warming the room without eating wall space. All the electrical work in the bathroom zones is installed to the wiring regulations and certified under building regulations.
Bathrooms in Pinner terraces are often tight, squeezed into the closet wing or a boxroom, so clever planning earns its keep. Wall-hung basins and toilets, a walk-in shower instead of a bath, and a concealed cistern can transform how a small room feels and works. We set out the layout to make the most of every awkward corner and sloping wall, particularly in loft conversions where the pitch of the roof limits standing height.
We fit the full range, from traditional suites that suit a period cottage to sleek contemporary walk-in showers, matched to the age of the house. Tiling, lighting, heated towel rails and quality brassware finish the room. Working in an occupied Pinner home, we protect the landing and stairs, keep dust down and get you back to a working bathroom as quickly as the tanking and tiling allow, without cutting corners on the parts that stay hidden.
Pinner homeowners choose GS Renovation for bathrooms because the parts that matter most, the tanking, falls, drainage and ventilation, are the parts you never see, and getting them wrong is expensive. One team handles the plumbing, waterproofing, tiling, heating and electrics, all to building regulations. With 30-plus years in HA5's period homes, we know how to fit a proper bathroom into a tight, older space.

FAQ
Check what has been left out before deciding. Cheap bathroom renovation quotations in Pinner tend to be rather light on approvals and reinstatement, and work started without Harrow Council sign-off becomes expensive when the HA5 property is sold. GS Renovation includes both as standard. We would rather lose the job than win it by omission. Ring 07472 424 226 and GS Renovation will explain what a complete Harrow quotation should contain, and what it should not. 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.
We will not open your house and disappear. Bathroom renovation at an HA5 property is scheduled so that the Pinner job runs continuously through to making good and sign-off. GS Renovation keeps one team accountable rather than passing the Harrow site between subcontractors. If a genuine emergency pulls anyone away you are told immediately, not afterwards. The Pinner programme and the Harrow Council inspection dates are reissued whenever anything at the HA5 property changes.
Over 30 years of hands-on experience sits behind every judgement made on your HA5 site. That is our founder's, and it shows in how bathroom renovation is scoped in Victorian and Edwardian terraced housing before anything is committed. GS Renovation is fully insured, handles Harrow Council approvals and leaves the Pinner site clean each day. Ring 07472 424 226 and speak to the people who will actually do the Harrow work. Ask to meet the named manager beforehand.
Not for internal work. Converting a bedroom to a bathroom in a Pinner 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 HA5 property may need permission in a conservation area.
Only where the property genuinely warrants it. Bathroom renovation is priced from what the HA5 survey finds rather than from the age on the deeds, so a well-maintained Pinner house of that period is not loaded with a period premium. GS Renovation itemises so you can see the reasoning. Comparing that against another Harrow quotation is straightforward. Ring 07472 424 226 and we will explain how a bathroom renovation quotation is built up at HA5.
Yes. Small bathrooms in Pinner terraces suit a walk-in wet room well, freeing up space by losing the bath and shower tray. The essential work is fully tanking the floor and walls, forming the right falls to the drain, and reinforcing timber floors so nothing flexes. We also make sure ventilation is adequate. No planning permission is needed, but the electrics and drainage follow building regulations.
We do, and the borough boundary is not something we price against. What decides whether GS Renovation takes a bathroom renovation project is capacity and scope rather than whether the HA5 property is in Pinner or elsewhere in Harrow. Quotes are free and carry no obligation. Call 07472 424 226 for current availability. Aftercare visits reach a North West London address just as easily. Nothing is owed for the HA5 survey or for the written quotation.
