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.
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.
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.
Choosing bathroom tiles
Porcelain tiles are durable and low-maintenance, suited to floors and high-use areas. Ceramic is cheaper and easier to cut, often used on walls. Large-format tiles look sleek with fewer grout lines but need a flatter substrate to fit well — worth discussing with your fitter before ordering.
Workmanship guarantees on bathroom fitting
Ask what's covered by a workmanship guarantee specifically — tiling and waterproofing failures (the most costly to fix if they go wrong) should be explicitly included, not just the visible fixtures. Fixture manufacturer warranties are separate again and worth keeping paperwork for.
Choosing taps and shower valves
A thermostatic shower valve maintains a constant temperature even if water pressure elsewhere in the house changes (someone flushing a toilet, for example) — worth the extra cost over a manual mixer valve for most households. Tap finish (chrome, brushed nickel, matte black) is largely aesthetic but affects how easily fingerprints and limescale show.
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.
Disabled Facilities Grants for bathroom adaptations
A Disabled Facilities Grant can help fund accessibility adaptations like a level-access shower or grab rails, subject to a means-tested assessment via your local council — worth researching eligibility before assuming an adapted bathroom is unaffordable, since the process and criteria vary by council.
