High Sierra Showerheads, LLC The recently patented nozzle in the High Sierra shower heads is designed to break up a 1.5 stream of water (40% less water than traditional 2.5 gpm low flow heads)into a full and invigorating spray of large droplets. The spray has just the right force for rinsing long hair and is very satisfying. The other big advantage of this design is that all the water enters and exits the shower head through single orifices virtually eliminating clogging. The payback in savings (water and the energy to heat it) is usually under 3 months. All parts used to manufacture High Sierra shower heads are machined, molded, and assembled in California.
