Thank you for your question. The Delta Pivotal 17 Series Integrated 3-Function Diverter Trim T27899-SS is not designed to be used with a tub spout. However, you may connect a non-diverter tub spout to one of the diverter ports as a temperature tester. Since the flow rate from the spout would be lower than a standard installation, we do not recommended to use it as a tub filler.
Alternatively, you can install an R10000 and R11000 valve with corresponding trim kits. The tub spout should be connected to the bottom port of an R10000 valve to provide sufficient flow to fill a tub.
