Building a house/need help with master shower PEX line routing

[jmed999]

Hello and thanks in advance for your help!

We are building a house and the builder's plumbing sub is doing the rough in now. In the master bath we have a shower head and a hand shower on a sliding rail.

Each of those will have its own volume and temperature control (no diverter). Should each volume temp control (https://www.deltafaucet.com/bathroom/product/T17093-RB) line come directly off the main 3/4" PEX line or can they both be piped off the same branch line. The plumber is connecting them both to the same branch line...seems like to get full flow for each at the same time (which is important to us) they would each need to come off the main 3/4" PEX line.

Thanks again for your help!

Biggest pipe possible as close as possible to the point of use. However, once you get there you have a water-saver valve that pees on your birthday cake.
