Hello, mjbphx. Thank you for your question! Water will flow to the tub spout first and can then be diverted to the shower head or hand shower. This is the recommended installation for a tub and shower setup.
The T11900 6-Setting Diverter Trim Kit will allow you to use the third port of the R11000 Diverter Valve. You may connect a non-diverter tub spout to the R11000, but the flow rate will be reduced by about 1 GPM when compared to the bottom port of the R10000 valve.
Best regards, Jon
