From The Manufacturer

At just 0.2 inches, the SimpleSpa is one of the thinnest attachments on the market. Its thin profile keeps your toilet seat level, unlike thicker attachments. This not only reduces the unsightly gap between your toilet seat and toilet bowl, it also eliminates the stress points that can cause seat cracking. 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 comes with everything for a quick, easy installation, including a durable braided metal hose and metal t-valve. Features like the nozzle guard and retractable nozzle ensure that your wash is always clean and hygienic.
