Delta Shower Systems are one 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 all the necessary Rough-in Valves and component pieces to make this package fully ready to install. This Dual Handle Shower Control Features a Delta’s highest flow rate Thermostatic 17T Cartridge with an 8.53 GPM flow rate at 80 PSI. This Delta Shower System has been expertly optimized for this water output and will have good water pressure even at 60 PSI. It features a separate Temperature and Volume Control Handle. The Six Setting Shower Diverter Handle Control with Delta R11000 Universal Diverter Rough-In Valve allows you to create a custom Delta Shower system. The Diverter Valve sits in between your main shower mixing valve and your peripheral shower system sprays. The Diverter sends water to the different shower sprays. The 6-Setting Diverter features 3 individual positions and 3 Shared positions, allowing you to run any shower system spray individually or any combination of 2 you desire at the same time.
