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. 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. 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. You can turn on the showerhead by itself, the hand shower by itself, or both together. This system is optimized for water pressure so both can be run at the same time.
