This Delta Tub and Shower System is easy to install because it requires only one rough-in valve. Most other Systems require several rough-in valves and a complex network of plumbing to be installed in your wall. This results in expensive installation costs and requires more significant remodeling plans. We have a smarter solution. All you need is plumbing for a normal shower faucet and you can enjoy the benefits of a full Shower System. When you initially turn on the water it will flow from the Tub Spout. Pull-up the Tub Spout Diverter and the water will switch to the Shower. The 3-setting Shower Diverter allows you to choose your preferred setting. Delta Shower Systems are some of our best selling products but we know they can be a little tricky to set-up. There are many components that are required to build a Custom Shower System. We have included the necessary Rough-in Valve and all component pieces to make this package fully ready to install.
