Bathroom regulations, FAQ
Do I need building control sign-off for a bathroom refit? Usually not for a like-for-like refit, but new electrical circuits or moving significant plumbing may need it, handled via the relevant registered tradesperson. Can I do my own tiling? Yes, tiling itself isn't regulated — it's the electrics and plumbing behind it that are.
Choosing a bathroom suite
A close-coupled toilet is the standard, affordable choice. A wall-hung toilet looks sleeker and is easier to clean around but needs a concealed cistern built into the wall, adding cost and reducing space behind the wall for other services. Similar trade-offs apply to countertop vs inset basins.
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.
Aftercare after a bathroom refit
Keep any electrical certification (if new circuits were added) and product warranties from the suite and fittings together. It's worth checking silicone sealant around the shower/bath every year or two and re-sealing if it's cracking, since this is a common early failure point that's cheap to maintain.
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.
Bathroom condition and selling your home
A recently refitted, well-maintained bathroom is a genuine selling point, and any electrical certification from work done during the refit is worth keeping for buyers' solicitors. Visible damp or poor grouting, on the other hand, is one of the more common things a buyer's surveyor flags.
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.
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.
