Why bathroom electrics need a registered electrician
UK wiring regulations split a bathroom into zones based on distance from water, restricting what electrical fittings can go where. This makes bathroom electrical work notifiable under Part P — a fitter doing the tiling and plumbing will typically bring in (or should) a registered electrician for any new sockets, extractor fans or lighting circuits.
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 plumbing work and WaterSafe
Moving or adding plumbing (a new shower, relocated toilet) should follow Water Fittings Regulations, the same rules a WaterSafe-registered plumber works to. If your bathroom fitter isn't a registered plumber themselves, ask who does the plumbing side and whether they're WaterSafe registered.
Bathroom fitting in older properties
Older properties sometimes have uneven floors, narrower doorways, or pipework not originally designed for modern water pressure — a fitter working on a period property will usually assess these before quoting for anything beyond a straightforward like-for-like swap.
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.
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.
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.
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.
