Details

Fitting a deep waste into a tight floor void is incredibly annoying. Consequently, installers often carve out structural floor joists or raise the shower tray, ruining a sleek bathroom entry. Furthermore, cheap generic low-profile traps significantly choke drainage flow. As a result, you find yourself standing ankle-deep in wastewater while soapy scum threatens your tray’s silicone lines.

Fortunately, installing this authentic McAlpine shower trap completely solves these space and flow restrictions. Specifically, the compact 95mm depth slides cleanly beneath low-slung trays without forcing structural modifications. Additionally, the premium interior hydraulics clear a swift 50L/min to handle modern shower systems effortlessly. Therefore, you get an exceptionally clean chrome finish that keeps your tray dry and perfectly draining.
