Bathroom renovation costs in London, 2026
What a proper bathroom refit actually costs in London in 2026 — by scope, by finish level, and the hidden costs nobody quotes for upfront.
A full bathroom refit in London in 2026 typically lands between £8,000 and £35,000, depending on size, specification, and how much of the structure changes. That range is wide for a reason — the word "bathroom" covers everything from a clean tile-and-paint refresh to a wet room with underfloor heating, a freestanding bath, and bespoke joinery. Here's what actually drives the number.
The four cost tiers
£8,000 – £12,000 — Like-for-like refresh. Suite replaced in the same footprint, new tiles, sealant, fittings. No pipework moved, no walls touched. Honest mid-range brands (Mira, Roca, Hansgrohe entry-level).
£12,000 – £18,000 — Full refit, same layout. Everything comes out to the studs. New waterproofing, new first-fix plumbing and electrics, proper tile backer board, fresh extraction. Mid-to-upper brands (Hansgrohe, Grohe Essentials, Villeroy & Boch).
£18,000 – £28,000 — Reconfigured bathroom. Layout changes, wall removal or repositioning, often a wet room or walk-in shower with a linear drain. Stone or large-format porcelain tiles. Better fittings (Crosswater, Vola entry, Lefroy Brooks).
£28,000 – £35,000+ — Design-led. Freestanding bath, bespoke vanity, underfloor heating, specialist finishes (Venetian plaster, natural stone, brass or nickel fittings), custom joinery, concealed cisterns, proper lighting design. High-end brands (Waterworks, Vola, Drummonds).
What's included in a proper quote
A proper London bathroom quote accounts for: strip-out and dust protection, waste removal, first-fix plumbing, first-fix electrics (including RCD-protected circuits), tanking or waterproofing, tile backing, tiling labour, tile adhesive and grout, fittings and sanitaryware, second-fix, sealant, final clean, and a snagging visit. If any of those aren't itemised, ask why.
The hidden costs nobody quotes for
- Joist reinforcement. If you're fitting a stone-resin or cast-iron bath, the joists often need doubling up. A surveyor's call.
- Extraction to outside. Bathrooms need mechanical extraction ducted to outside — old "terminate into the loft" setups fail building regs and rot your roof.
- Soil stack relocation. If you move a WC more than a couple of metres from the stack, the pipework cost climbs quickly.
- Lead pipes. Period Victorian and Edwardian London houses often still have lead supplies. Discover this on day one, not mid-project.
- Asbestos. Artex ceilings and older tile adhesives can contain it. Pre-2000 properties need a survey.
Timeline
A like-for-like refresh runs 7–10 working days. A full refit is 3–4 weeks. A reconfigured design-led bathroom is 5–8 weeks — longer if bespoke joinery or stonework is involved.
Why London costs more
London tradespeople, parking permits, skip licences, tight access in period properties, and the sheer logistics of delivering materials through narrow corridors all push costs up roughly 20–30% versus the rest of the UK. That's the reality, not a markup.
