Thnak you for your question. The flow rate for the Delta Classic Roman Tub Trim T4705-25, has a flow rate of 2.5 gpm from the handshower. The flow rate from the tub spout varies depending on the water pressure going to it. Below, I have included and Technical Specification sheet with a flow rate chart, in the bottom right handle corner, for all roman tub faucets.
