This Delta Shower System is smartly designed and economical. It is easy to install because it requires only one rough-in valve. Many other Shower 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. Making use of Delta’s 3-setting Diverter, we are able to offer a better solution. All you need is plumbing for a normal shower faucet and you can enjoy the benefits of a full Shower System. After turning on the water with the Shower handle, the 3-setting Diverter allows you to select 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. This Dual Handle Shower Control Features a Delta Monitor 17 Series Cartridge with a 6.98 GPM flow rate at 80 PSI. It features a separate Temperature and Volume Control Handle.
