This Modern Collection bundle offers a streamlined, contemporary design and the components you need for a complete shower. 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.

Perfect for a custom shower. Components can be place virtually anywhere. The rain head provides exceptional flow and coverage. Will never go back to a "regular" shower head. The temperature control is "touchy" at the high end and it's easy to make the water too hot. No problem for an adult.. Dave. Seabeck, WA. Tue Jun 16 2026
