What size pipe and fittings are you using? 15mm copper with soldered fittings take the least room up plastic fittings take much more room up?
why is it only half height that will leave a ledge for water to sit on?
Thanks for that Chaz. It's an internal block wall, I can't run pipes through it from the adjacent rooms so I have to build this duct, I'm not fitting an electric shower, the pipes are just 2m from the boiler and tank so feed and pressure is good enough to keep it a simple tap arrangement (with thermal cut out).
The duct is half height so that I get a 'shelf' I thought about this at first because it could give probs if not constructed right of course, but as long as it has a fall and is watertight it should be ok, it's going to be 500mm away from the shower head. The duct width is going to be 110mm with a removable tile at the side so plenty of room for plastic fittings
