Bathroom Renovations Across London & the South East
Complete bathroom renovations — plumbing, electrics, tiling, waterproofing and finishes — delivered by one accountable team.
Haarth delivers complete bathroom renovations, wet rooms and en-suites across London and the South East. From tanking and first-fix plumbing through to bespoke tiling and lighting, every trade is managed in-house with a fixed quote and typical completion in 10–20 working days.
What a bathroom renovation involves
A proper bathroom renovation covers every trade behind the tiles: strip-out, waste and pipework re-routes, waterproofing (tanking), electrical first-fix for lighting and extraction, plastering, tiling and finally the sanitaryware and brassware. Haarth manages the full sequence so nothing gets missed and there's no gap in accountability if something goes wrong later.
We work in occupied family homes, listed properties, apartments and rental units across London and the wider South East. Every project runs with dust-sheeting, floor protection and daily site cleans so day-to-day life carries on with as little disruption as possible.

Waterproofing and long-term durability
The single biggest cause of bathroom failure is poor waterproofing. Every Haarth bathroom is tanked to the correct spec for the substrate — cementitious tanking on concrete, gypsum-compatible membranes on plasterboard — before a single tile is laid. Falls are set with laser levels, silicone lines are pointed to a consistent bead, and we photograph the first-fix behind the tiles so there's a permanent record of what's in the wall.

Frequently asked questions
How long does a bathroom renovation take?
A standard family bathroom typically takes 10–15 working days on site. Wet rooms, en-suites requiring new soil pipework, or high-end tiled bathrooms usually take 15–20 working days.
How much does a bathroom renovation cost in London?
A standard bathroom refit in London costs £6,500–£12,000, an en-suite or wet room £9,000–£18,000, and a bespoke high-spec bathroom £20,000 or more. Haarth provides a fixed quote after a free on-site survey.
Can I stay in the property during the works?
Yes — most clients do. If it's the only bathroom in the property, we can phase the work so the WC is usable for the shortest possible period.
Do you supply the tiles and sanitaryware?
We can supply everything under one fixed price using our trade accounts, or fit items you've bought yourself. Most clients prefer a hybrid — trade-supplied plumbing and second-fix, retail-supplied tiles and brassware.
Do you provide a guarantee?
Every Haarth bathroom renovation is backed by a 12-month workmanship guarantee, in addition to any manufacturer warranties on appliances and sanitaryware.
