I have a flat that has water tank. There's ensuite with shower, and another bathroom with a bath. I'm going to renovate the bathroom and ideally wanted to change bath into shower. Is this a bad idea, considering if I want to rent this flat later (or sell). My understanding is that with water tank, you'd use all water to fill up the bath (if it's enough) so it isn't practical to take a bath in the first place. Any thoughts?
