Details

Cramming a high-flow shower waste into ultra-tight modern floor joists is an absolute nightmare. Consequently, standard deep traps force you to cut dangerously deep into timber joists or raise the entire shower tray. Therefore, you face major structural complications and ugly, stepped bathroom layouts. Furthermore, slow drainage from shallow setups causes frustrating water pooling and immediate basin flooding. As a result, restricted voids often lead to strained, leaky pipe configurations. Consequently, this clunky setup creates hidden tracking leaks, warping your floorboards and causing costly ceiling damage below.

Fortunately, installing this ultra-shallow McAlpine shower drain waste solves these restricted space and slow-draining headaches completely. Specifically, the ultra-compact 70mm deep body layout slides effortlessly into the shallowest floor spaces without needing structural modifications. Therefore, you bypass the need for lifting joist frameworks or compromising your flooring. Additionally, the advanced internal design unleashes a powerful 34 litre per minute flow rate to clear water instantly. The removable 110mm brass flange also allows you to clear debris directly from above. Consequently, you get an incredibly reliable, low-profile, and permanently watertight installation.
