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.
Walk-in showers and wet rooms, what's different
A walk-in shower needs careful floor falls (gradient) toward the drain to work without a shower tray — this is more technically demanding than fitting a standard shower tray and enclosure, and a poorly built one is a common source of water pooling or leaks. A full wet room takes this further, tanking the whole floor.
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.
Planning an en-suite bathroom
Adding an en-suite usually means extending plumbing and sometimes electrical circuits into a new area, and ventilation (an extractor fan, by regulation) becomes more important in a smaller enclosed space. Worth planning the layout around existing pipe runs where possible to control cost.
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.
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.
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.
