Talk:Install Bar Shower Valve - stud wall

how would you fit one of these in a solid wall

You would need to chase out the wall, set the pipes in position, and then plaster it all back in again. --John Rumm 02:34, 27 October 2008 (GMT)

Would you need to wrap the pipes with denso tape or plaster straight onto them?

If rendering over copper, then you should use denso. IIUC, copper is ok with gypsum plaster though so you could plaster in. With plastic pipes it is a good idea to slide them up a sleeve of some sort (i.e. a larger bore plastic, or a conduit of some sort) since the plastic does tend to expand a fair bit when it heats up. You can also do it with careful application of some expanding foam prior to plastering - that allows a little expansion room in the chase. --John Rumm 18:33, 28 October 2008 (GMT)
