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.
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.
What affects the cost
Cost depends on whether pipework and electrics need moving (not just swapping fixtures in place), the tiling area, fixture quality, and whether structural changes are needed (like removing a bath for a walk-in shower). Moving a toilet's position, in particular, is one of the more expensive changes because of the soil pipe work involved.
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.
Shower screens vs shower curtains
A glass shower screen looks cleaner and is easier to maintain long-term than a curtain, but costs more and needs to be fitted correctly to avoid water escaping at the edges. A curtain is the cheaper, more flexible option, particularly for an over-bath shower.
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.
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.
