This anti-smell shower waste trap is designed to be installed in a shower tray hole that is approximately 50mm in diameter. This high flow waste uses a vented dome for quick removal of water in the shower. The outside diameter of the spigot is 9.7mm. The diameter of the chrome finished top cover is 80mm and can easily be detached after installation to reveal a small removable basket that will catch hair and other shower debris. This can be done from the top of the shower tray. The trap is supplied with two rubber washers that will sit above and below the tray surface after installation. The distance between the top of the chrome dome to the base of the waste trap is 90mm. The diameter of the base of the trap is 90mm. This trap is designed for use with 40mm 1 1/2 inch waste pipes. Distance from below tray to bottom of the trap is approximately 60mm. There is a side spigot that is undrilled but could be drilled for use for the drainage of a steam generator. Used on the Geneva (S-DV015).
