SPIRAL DESIGN: The spring hose is highly stretchable. It can be freely stretched between 43cm (17") and 2.3m (90"). The maximum usage time is 2.3m (90"). It solves the problem of the shower hose rubbing against the floor and being messy, making the bathroom and toilet tidier. HIGH-QUALITY MATERIAL: The hose is made of high-quality environmentally friendly materials with good flexibility and kink resistance. The interface nut is made of stainless steel. It is robust and durable. Used with the sealing washer (included in the interface or packaging), the nut can effectively prevent water leakage and ensure a firm interface connection. WIDE APPLICABILITY: The telescopic hose interface uses the standard 1/2-inch interface, which is suitable for general connection of bathroom accessories such as handheld showers, bathroom spray guns, sink faucet showers, toilet sprayers, bidet sprayers, diaper sprayers, and pet sprayers. The hose can shrink automatically, saving space and facilitating storage and organization. QUICK INSTALLATION: The bathroom spray gun hose requires no tools. Easy to install. Insert the sealing washer and tighten it by hand to complete the installation. It can be easily installed by one person.
