Isolate services & protect finishes – shut water, cover nearby tiles, heat‑wire probes or underfloor elements.
Remove existing fixture(s) – unscrew faceplates, cut silicone, disconnect concealed pipework or carrier frame bolts.
Inspect & patch waterproof layer – assess membrane integrity; apply liquid tanking or replacement collar where disturbed.
Install new fixture(s) – fit updated thermostatic mixer, wall‑hung WC bowl, flush plate, linear drain or grab rails; torque to spec.
Reconnect & pressure‑test water feeds and waste; balance mixer temperature if thermostatic.
Silicone seal & finish – use sanitary‑grade silicone and colour‑matched grout/trim as required.
Commission & tidy‑up – run shower for 5 min, check falls to drain, wipe glass, remove debris.

Single mixer or drain swap: 3 – 5 hours.
Add wall‑hung WC or multiple fixtures: 1 full day.
Extra time drivers: membrane drying (4 – 12 h), tile‑setting & grout cure, restricted access behind tiled boxing, hidden leaks, or cutting into reinforced screed.

Will you test the existing waterproof membrane and include patching in the quote?
Are new fixtures WRAS‑approved and supplied with thermostatic safety features?
How will you protect underfloor heating cables or wet‑room gradients when removing tiles?
Is debris removal and disposal (including heavy ceramic) included?
What warranty do you give on both parts and workmanship, especially watertightness?
Do you carry public‑liability insurance that covers water damage to adjoining rooms?
What is the lead time if concealed valves or carrier‑frame spares are back‑ordered?

Access & parking: reserve a space close to the entrance; wet‑room fixtures are bulky and fragile.
Confirm tile stock: keep spare tiles on‑site for any that must be removed; matching discontinued ranges can delay finish.
Photograph shut‑off valves & manifold before work begins; handy if isolation is needed again later.
Drying & cure times: plan bathroom downtime—membrane patches and silicone need 12–24 h before full use.
Ventilation: run extractor or dehumidifier during cure to avoid silicone bloom.
Detailed written quote: include membrane repair, tile work, disposal and VAT so the bill lands within the £600 – £1,800 range shown above.
