The Wondercap Tile Shower Drain Outlet is designed to prevent shower-pan-liner leaks and to stop construction waste from blocking the drainpipe.
The Wondercap provides an accurate connection between the waste pipe and strainer while adding protection, says the manufacturer. Constructed from no-stain polypropylene and manufactured with an anti-bacterial agent, the product has a removable strainer with a simple turn-and-lock mechanism that reportedly allows for quick access and cleaning. Pricing starts around $45. wondercap.com
