We are installing an air tub in the master bath that has a preformed built in waterfall fill on the back side of the tub. There are no controls for the water to turn off and on or to adjust hot and cold. We need to cut holes for the controls plus a hand held shower. We do not need a spout. Just the handles and the shower. Since all we can find is a tub kit that has a roman spout, we are at a loss for how to complete this DIY project. Everyone has told us we have to buy the kit with the spout and just "toss" the most expensive part which seems rediculous. Can anyone gives ussomeinformation as to how to complete this install.
