Walk-in showers and wet rooms, what's different
A walk-in shower needs careful floor falls (gradient) toward the drain to work without a shower tray — this is more technically demanding than fitting a standard shower tray and enclosure, and a poorly built one is a common source of water pooling or leaks. A full wet room takes this further, tanking the whole floor.
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.
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.
Bathroom ventilation, why it's required
An extractor fan (or adequate window ventilation) is a Building Regulations requirement in bathrooms, managing moisture that would otherwise cause mould and damage to fittings and decoration over time. A bathroom without a window typically needs a fan wired to run for a period after the light is switched off.
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.
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.
Bathroom lighting and IP ratings
Lighting near water (over a shower, close to a bath) needs to meet a minimum IP (ingress protection) rating for that specific zone — not every light fitting is suitable everywhere in a bathroom. This is part of what a registered electrician checks as part of the notifiable electrical work.
