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 fitting in older properties
Older properties sometimes have uneven floors, narrower doorways, or pipework not originally designed for modern water pressure — a fitter working on a period property will usually assess these before quoting for anything beyond a straightforward like-for-like swap.
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.
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.
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.
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.
Standard radiator vs towel rail in a bathroom
A heated towel rail is generally less powerful as a room heater than an equivalent-sized standard radiator, so in a larger bathroom it's sometimes worth having both, or a larger towel rail sized properly for the room, rather than assuming any towel rail will adequately heat the space.
Bathroom plumbing work and WaterSafe
Moving or adding plumbing (a new shower, relocated toilet) should follow Water Fittings Regulations, the same rules a WaterSafe-registered plumber works to. If your bathroom fitter isn't a registered plumber themselves, ask who does the plumbing side and whether they're WaterSafe registered.
