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.
Bathroom condition and selling your home
A recently refitted, well-maintained bathroom is a genuine selling point, and any electrical certification from work done during the refit is worth keeping for buyers' solicitors. Visible damp or poor grouting, on the other hand, is one of the more common things a buyer's surveyor flags.
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.
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.
Making the most of a small bathroom
A corner shower, wall-hung suite, and a mirrored cabinet instead of a separate cabinet and mirror are common ways fitters maximise a small bathroom without a full structural change. Layout planning matters more in a small space, where a few centimetres can determine whether a design actually works.
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 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.
Bath vs shower-only, deciding for resale value
Removing the only bath in a property to fit a larger shower can affect resale appeal to buyers with young children, even if it suits your current needs better. Worth considering if this is your only bathroom and you're not planning to stay long-term.
