Background we live in a 300-500 year old cottage. Has a downstairs shower room with electric shower and an upstairs bathroom with no shower.
We wanted to put in a "proper" shower to the downstairs room but as we have no floor cavity for pipes and it's at the other end of the house to the hot water cylinder plumbers say this isn't possible.
Same lack of floor cavity means we probably can't put one in the main bathroom either (steeply sloping ceiling over the bath so can't go there) so nowhere for the waste to run.
Any bright ideas, or what's the least worst electric shower so I don't just get a lukewarm dribble of a shower every day?
