Did my builder screw up again?


We are totally re doing our ensuite bathroom. There WAS a tub and a shower. We got rid of the tub and are having a large custom shower built. The shower has 2 independent shower heads. What I am worried about is that they capped the water lines from the tub and split the shower line to the 2 separate shower heads. Would I not have gotten a lot more water volume by using both sets of lines that were there instead of splitting one??

so you are saying that you are putting 2 shower valves? id make them feed each one seperate, a 1/2 inch line wont give you a lot of pressure with 2 of todays wasteful showerheads. wht do the installation instructions say about the water line requirements?

yup, 2 separate valves. The heads are rated at 2.5gpm and I was told a 1/2 inch line gives about 5 gpm.. so we should have the minimum amount of water required.
I talked to my cousin, who is an engineer. He is pretty sure they would NOT have run 2 dedicated lines to the second story all the way from the basement and that it is likely a single line that was split it the wall or the floor below.
Thoughts?

If the 2 lines from the basement feed the whole bathroom then they are probably 3/4"- which is pretty standard. They probably branched 1/2" off to feed the tub.
It is not uncommon to feed two fixtures with 1/2" a supply

why not do one control and a selector switch. That way you don't have two separate temperatures

Not to get too personal, but we like our own temperatures.
Thanks everyone for the feedback.

This is a more reasonable way to do it if you don't have a 3/4" line to feed two shower valves.
