New open box Watermark thermostatic shower valve with built in two way diverter. This shower valve has the ability to preselect water temperature and doing so will help conserve water. This valve has a paraffin wax element which maintains water temperature within +/- 1.8°F.  This valve compensates for water pressure fluctuations, which helps prevent scalding and has a safety button set at 100°F to prevent accidental scalding. This valve has high flow rates to allow for multiple shower applications. These are very expensive at the dealer but you can buy mine at a bargain and have it shipped to your door for free. Please make sure this is the correct part for your needs and please study the pictures carefully.  Ask any questions you may have.
