Bring clean lines and subtle details to your bath with the Knoxville bath collection. Delta showers with Monitor pressure-balance 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. While other products may gather unsightly mineral buildup over time, soft rubber Touch-Clean spray holes allow any mineral residue to simply be wiped away for an instantly refreshed look with no need for soaking or the aid of chemical cleaners. WaterSense labeled faucets, showers and toilets use at least 20% less water than the industry standard helping you save water without compromising performance. You can install with confidence, knowing Delta products are backed by our lifetime limited warranty.
