Thinking about completely refurbishing a bathroom this year. A largish area is taken up by a built in cupboard which contains shelving for towels etc and a vented indirect cylinder. It occurs to me that I could free up sufficient space to install a walk in shower if I relocated the cylinder upstairs in the loft space. The water tank is on a stand around 70cms high so I wondered about installing a new unvented indirect cylinder which would get around the problem of lack of head. There are a couple of
150x50 joists in the area and plenty of block walls supporting them.Grateful for any comments or suggestions.
