- Complete the look in your bathroom with a shower from the Classic 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, Delta 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. You can install with confidence, knowing that Delta showers are backed by our Lifetime Limited Warranty.
