We had the chrome oxygenics on our old tt. It is chrome finish but plastic body. The hose was a universal screw on. Our oxygenics was purchased almost 3 yrs ago and came without the shut off valve. DH bought a shut off valve at home depot that worked well. Whole thing was east to install. We sold the tt with it still in. No issues with it. Yes it does increase your water pressure when showering but it actually uses less water than a regular shower head.
