Familiar geometries and subtle curves in the Tetra bath collection combine to bring a sleek, architectural look and feel to the bath. Delta showers with Tempassure thermostatic valves are engineered to make sure you don't experience a sudden and possibly unsafe change in water temperature as a result of running water elsewhere, such as using a dishwasher, flushing a toilet, or running a washing machine. Lumicoat finishes easily wipe clean without the need for cleaners or chemicals and is guaranteed to resist mineral buildup and hard water stains. The ultra-sleek surface repels liquids, resisting water spots and staying cleaner longer, so your faucet’s most commonly touched areas stay beautiful. Integrating separate controls on one trim with the multichoice integrated shower diverter allows you to simply set the water at your preferred temperature and turn the shower on or off with the volume control handle, without interrupting your set temperature. You can install with confidence, knowing Delta products are backed by our lifetime limited warranty.
