It's a rather basic question but I can't find straightforward answers anywhere.
We're [re]designing an area in our house and want to install a new shower (among other things). In order to plan the layout we need to know how much space a shower needs. It might be a dedicated shower room or, if it fits, we might squeeze it into the existing downstairs loo.
So any advice, pointers, etc. as to minimum and/or sensible sizes for a shower would be very welcome.
