Bathroom Plumbing Services in Westminster

Vetted & insured engineers Clear pricing before work starts G3-qualified for unvented cylinders No gas work — plumbing only

Swapping a basin, moving a toilet, converting a bath to a walk-in shower: the plumbing is the part that decides whether a Westminster bathroom project goes smoothly. We do first fix, second fix, or the whole wet-side scope.

Westminster water notes: Westminster shares London's hard, chalk-influenced supply — limescale works relentlessly on cylinders, boiling-water taps and shower valves in the borough's high-specification stock. Westminster runs from Georgian townhouses and mansion blocks in Marylebone and Pimlico to serviced apartments and mews conversions — much of it listed, all of it access-sensitive, with porters, concierges and quiet-hours to respect. Mains supply here is managed by Thames Water.

Small works: the everyday bathroom list

Leaking basin and bath wastes, failed traps, dripping or seized taps and mixers, running and leaking toilets, showers running cold or weak, silicone strip-and-reseal, resealing around trays and baths, replacing wastes and plugs, fixing towel-rail weeps on the wet side, and swapping like-for-like sanitaryware. Most are one-visit jobs in Westminster, priced before work starts.

Refits: first fix and second fix

For Westminster bathroom projects we quote the wet-side scope in two clean stages: first fix (rerouting supply and waste to the new layout, testing before close-up) and second fix (fit, connect and commission everything after finishes). Correct waste falls, accessible isolation and a documented pressure test before boarding are non-negotiables — they're the difference between a bathroom and a future claim. Westminster runs from Georgian townhouses and mansion blocks in Marylebone and Pimlico to serviced apartments and mews conversions — much of it listed, all of it access-sensitive, with porters, concierges and quiet-hours to respect.

Finding bathroom leaks properly

Bathroom leak diagnosis is sequencing: static supply joints first (they leak constantly), then each waste under flow, then seals under spray. The method matters because the fixes differ by an order of magnitude — a trap washer versus a tray reseat. Our Westminster engineers test before they quote, so you're paying to fix the leak you actually have.

Bathroom plumbing costs in Westminster

Small works from £95 with standard parts included. Sanitaryware swaps are fixed-quoted per item. Refit wet-side scopes are priced from the layout drawing or a site visit — first fix and second fix itemised separately so you can stage the spend. No Westminster job starts without an agreed figure.

Frequently asked questions

My bath drains slowly but the sink is fine — why?

Localised slow drainage points to that fixture's trap and branch — hair and soap build-up usually. If several fixtures slow together or gurgle, the issue is downstream in the shared run or external drains, which we route to our drainage partner honestly.

Can a bath be converted to a walk-in shower?

Commonly, yes: the supply adapts easily and the waste is re-routed for a low-profile tray, with the critical detail being fall to the existing stack and proper tanking before tiling. We handle the wet side and flag any structural implications early.

Water is coming through the ceiling under the bathroom — what first?

Stop using the bathroom, and if the drip is constant even unused, isolate the water at the stopcock — constant means supply-side. If it only appears after baths or showers, it's waste or seals: usable carefully, but book promptly.

Do you reseal baths and showers in Westminster?

Yes — full strip of the failed silicone, sterilise, dry, and re-seal with sanitary-grade sealant, with the bath weighted (filled) during curing so the new seal doesn't tear on first use. We also fix whatever the failed seal let through.
