Choosing taps and shower valves
A thermostatic shower valve maintains a constant temperature even if water pressure elsewhere in the house changes (someone flushing a toilet, for example) — worth the extra cost over a manual mixer valve for most households. Tap finish (chrome, brushed nickel, matte black) is largely aesthetic but affects how easily fingerprints and limescale show.
KBSA and TrustMark, what they actually mean
The KBSA (Kitchen Bathroom Bedroom Specialists Association) is the main UK trade body for the sector, though membership is limited to a few hundred companies nationally, so it's not something every bathroom fitter will have. TrustMark is a broader government-endorsed scheme covering many trades — worth asking which, if either, your fitter holds, rather than assuming either is universal.
Why bathroom electrics need a registered electrician
UK wiring regulations split a bathroom into zones based on distance from water, restricting what electrical fittings can go where. This makes bathroom electrical work notifiable under Part P — a fitter doing the tiling and plumbing will typically bring in (or should) a registered electrician for any new sockets, extractor fans or lighting circuits.
Planning an en-suite bathroom
Adding an en-suite usually means extending plumbing and sometimes electrical circuits into a new area, and ventilation (an extractor fan, by regulation) becomes more important in a smaller enclosed space. Worth planning the layout around existing pipe runs where possible to control cost.
Three steps to hiring the right bathroom fitter
First, ask to see photos of similar completed jobs, ideally local ones. Second, clarify exactly who does the electrical and plumbing work — the fitter directly, or a subcontracted registered tradesperson. Third, get a written quote that separates labour, fixtures and tiling.
Adding a downstairs WC or cloakroom
A ground-floor WC addition usually needs a macerator pump if gravity drainage to the existing waste isn't possible, which adds cost and a small amount of noise compared to a standard gravity-fed toilet. Worth discussing early since it affects where in the house a downstairs WC is practical.
Common bathroom fitting jobs
Bathroom fitters handle everything from a single fixture swap to a full refit: removing and replacing suites, tiling, waterproofing (tanking) around showers, and coordinating the plumbing and electrical work a refit needs. Many fitters manage the whole job themselves and bring in a plumber or electrician for specific parts.
Background checks and identity verification
Since bathroom fitting isn't gated by a single mandatory certification the way gas or electrical work is, checking trading history, a verifiable business address, and reviews referencing specific completed jobs matters more here than for some other trades.
