The comments above are helpful. As a generalisation, I would add that a family home retains its bath for young children (and, indeed young grandchildren); most adults opt for a shower these days. So great that you have a bath somewhere, albeit any young children would need to walk through the bedroom to get to it. Depending on how big your bathroom is actually, and your budget, we had a similar challenge and fitted a shower space with hinged shower door in a wet room style design so that the family bathroom had both bath and shower. The hinged door opens up the floor space and prevents the room being sprayed; in fact only the bath itself gets wet, and even then not significantly. This may be of interest. The room footprint in this case was 1.9m by 2.1m. Other things to consider include opening the bathroom door outwards to create better use of the floor space you have. We also moved the door in this case to fit the sink comfortably, and fitted a small bath (which is fine for children). Hope this helps in some way. Nick

What type of hot water supply is it? If you have a gravity system then make sure you don't get a monobloc type filler, the smaller connection limits the flow rate. If you have a pressured system or combi boiler (which runs at main pressure) then monobloc is fine.

Will it be Ok if your future 15 year old daughter is walking downstairs in pjs to have a shower at 11am on morning because she prefers the shower downstairs? What’s the route to the shower in relation to public space where you are entertaining friends? will guests have to queue to use the loo while she is bathing? We have en-suite with stand alone bath with hand held shower and separate cave shower - luxury by previous owner. Bath rarely used but looks amazing. Our teenagers share main bathroom with shower over bath. As Johnathan says speed is the essence of the game - bath rarely used by eldest only, shower is their preference. Another question is whether you are in forever home, or may sell in the future - bath preferred by families with very small children and many families see altering bathroom to reinstall bath with power shower for adults a game changer due to expense. The answer to your issue must include how your family like to bathe, the future of your home and the position of your downstairs bathroom.
