Thank you for your question, Richard! At 60 PSI, the flow rate for from the bottom port of an R10000-UNBX valve with a 17 series trim will be about 6.2 GPM and the R10000-UNWS will run at 5.7 GPM. High Flow (HF) valves are only intended for shower-only installations and will not increase the flow rate to the tub spout.
Best regards, Jon
