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.
Making the most of a small bathroom
A corner shower, wall-hung suite, and a mirrored cabinet instead of a separate cabinet and mirror are common ways fitters maximise a small bathroom without a full structural change. Layout planning matters more in a small space, where a few centimetres can determine whether a design actually works.
Noisy pipes and water hammer
A banging sound when a tap or toilet valve shuts off (water hammer) is usually caused by a pressure surge in the pipework, sometimes fixed by fitting a water hammer arrestor near the affected fixture rather than needing to replace pipework throughout.
How many quotes should you get?
Three is reasonable for most bathroom jobs. For a full refit, make sure each quote specifies the same suite brand and tile allowance, since bathroom quotes vary a lot based on fixture quality assumptions that aren't always stated upfront.
Accessible and adapted bathrooms
Level-access showers, grab rails, and raised toilets are common accessibility adaptations, sometimes eligible for a Disabled Facilities Grant depending on circumstances. Planning these alongside a wider refit, rather than as a separate later job, usually costs less overall.
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.
What a good bathroom quote should include
A proper quote should specify the suite brand/model (not just "a toilet, a basin"), whether tiling and waterproofing are included, whether electrical and plumbing work is covered directly or subcontracted, and what happens if hidden pipework issues are found once the old suite is removed.
