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 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.
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.
Grout and sealant maintenance
Grout and silicone sealant are usually the first things to fail in a bathroom, well before the tiles or suite themselves — re-sealing around a bath or shower every couple of years, and re-grouting where needed, extends the life of the whole installation for relatively little cost.
What a good bathroom quote should include
A proper quote should specify the suite brand/model (not just "a toilet, a basin"), whether tiling and waterproofing are included, whether electrical and plumbing work is covered directly or subcontracted, and what happens if hidden pipework issues are found once the old suite is removed.
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 lighting and IP ratings
Lighting near water (over a shower, close to a bath) needs to meet a minimum IP (ingress protection) rating for that specific zone — not every light fitting is suitable everywhere in a bathroom. This is part of what a registered electrician checks as part of the notifiable electrical work.
