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.
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.
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.
Why waterproofing (tanking) matters
Tanking is a waterproof membrane applied behind tiles, particularly around showers and baths, to stop water getting into the wall or floor structure below. Skipping this step is a common cause of hidden damp and rot that only becomes visible years later — worth confirming it's included, not assumed, in a refit quote.
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.
Bathroom flooring options
Vinyl flooring is cheap, waterproof and easy to fit, suited to budget refits. Porcelain tile is more durable and higher-end but needs a sound, flat subfloor. Underfloor heating compatibility and slip resistance (particularly around a shower) are worth discussing alongside the look you want.
Adding a downstairs WC or cloakroom
A ground-floor WC addition usually needs a macerator pump if gravity drainage to the existing waste isn't possible, which adds cost and a small amount of noise compared to a standard gravity-fed toilet. Worth discussing early since it affects where in the house a downstairs WC is practical.
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.
