15mm or 22mm when plumbing in a bath/shower.?

Unless your property has three or more bathrooms, there is no advantage in using 22mm piping for the hot water supply with a pressurised system. In fact, all that happens is the larger pipe will mean the hot water takes longer before it reaches the shower.
