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.
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.
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.
How bathroom fitting quotes work
Describe the current bathroom's layout and what you want changed — an initial estimate can follow, but a firm price usually needs an in-person visit, since existing pipework position and floor/wall condition significantly affect scope once work starts.
Bath vs shower-only, deciding for resale value
Removing the only bath in a property to fit a larger shower can affect resale appeal to buyers with young children, even if it suits your current needs better. Worth considering if this is your only bathroom and you're not planning to stay long-term.
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.
Grout and sealant maintenance
Grout and silicone sealant are usually the first things to fail in a bathroom, well before the tiles or suite themselves — re-sealing around a bath or shower every couple of years, and re-grouting where needed, extends the life of the whole installation for relatively little cost.
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.
