My in-laws got a quote for 18k for a bathroom renovation including adjustments for the elderly. It's in London, but I stll think it's very steep? It would include leveling the floor, removing a bathtub, sink and toilet and installing a walk-in shower with a seat (with a new electric shower, this is what they have now too), higher toilet 'with a bidet function' (not sure if they mean a 2-in-1, or with a bidet shower attachment) and rails on both sides, new wash basin with a vanity, a standing unit, towel rails, a heated towel rail (I have to ask if that is necessary because it would be opposite the current radiator, so pipes would need to be moved). I think the wall covering proposed is panels, not tiles, and floor is Karndean.
Do this seem right to you? I am torn, because I could design a prefectly nice and safe bathroom for them, and certainly make it look less like a hospital (which would matter at resale) but we don't live in the UK and don't know any London bathroom fitters who would be reliable and available, so I am wary of offering my help. Would it even be cheaper?
