I currently have 1/2" copper pipe supplying water to my tub/shower combination. I will not be able to change this in the near term, but will probably change it in 1 - 2 years. In the meantime, I am buying all new plumbing hardware for the tub/shower. Although all of the outlets (spout and showerheads) provide 1/2" connections, the valves and diverter are available in either 1/2" or 3/4" models.
When I get around to completely redoing the bathroom (and changing the size of the supply pipes) I expect to want to continue using as much of the plumbing hardware I am buying now as possible. I will probably want to add body jets to the shower at that time as well (once the supply pipes are sufficient to support multiple simultaneous showerhead use). If I install 1/2" valves now, I will need to replace them with 3/4" valves at that time, which is an expense I would love to avoid.
My question is this: Would I find myself having problems if I bought 3/4" valves now and simply connected the 1/2" supply via reducers? As I said, the outlets are 1/2" anyway, so it seems to me that the extra volume between the valves wouldn't make any difference. The salesperson at the store felt otherwise.
