We're remodeling our master bath and are considering a shower panel with one head and four wall sprays. My limited experience with such showers is that when they are all on at once the divided 2.5 gallons per minute trickles and fails to satisfy. We have good pressure and flow to this shower, but I'm worried that we'll be disappointed by the same divided trickle. If we install and are unhappy with the flow, will a pressure booster help? Or is there something we can do before the installation to ensure a decent flow?

Thanks for your help.

These new prefab shower panels are designed so they give you good flow at smallest GPM supply. They use micro sprays for body spray heads. If you boost up pressure, they will feel like needles when hitting your body. I would not try to increase the pressure.

See the enclosed photo: entire shower runs on one 1/2" copper supply at 30 PSI of pressure.

Just what I needed to know. Thanks, Milo.
