The SimpleSpa's durable brass and ceramic internal components won't corrode or wear down and are protected by the sonic-sealed outer shell. This secure attachment body offers multiple layers of leak protection. Customize your wash experience with a quick turn of the control knob. The SimpleSpa Dual Nozzle comes with all the parts needed for a standard installation, including a durable metal hose and metal t-valve. Features like the nozzle guard and retractable nozzles ensure that you wash is always clean and hygienic. Simple. Secure. Clean.
