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.
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 myths, busted
"Any tiler can waterproof a shower properly" — tiling skill and correct tanking technique aren't the same thing, worth confirming both. "A bigger bathroom always costs proportionally more" — layout and fixture choice often matter more than raw size. "Underfloor heating always needs a full re-floor" — some systems retrofit onto an existing subfloor.
Bathroom work in flats and conversions
In a converted property, check whether waste pipework runs independently or shares a stack with other flats — this affects what changes are straightforward versus needing wider building consent. Worth checking before committing to a layout change like moving the toilet position.
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.
Understanding the labour vs materials split
Tiles, the suite, and fittings are often a smaller share of the total cost than labour, particularly for a full refit involving tanking and tiling. A cheap quote is worth checking against the same fixture brands and tile spec as competing quotes, not just a lower labour rate.
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.
Accessible and adapted bathrooms
Level-access showers, grab rails, and raised toilets are common accessibility adaptations, sometimes eligible for a Disabled Facilities Grant depending on circumstances. Planning these alongside a wider refit, rather than as a separate later job, usually costs less overall.
