Details

Cheap plastic shower buttons and flanges frequently crack, scratch, or dull under daily foot traffic and heavy cleaning chemicals. Consequently, the waste top quickly looks worn out and cheapens the look of your entire enclosure. Furthermore, low-profile plastic traps often flex or warp over time, leading to slow, tracking leaks in hidden floor voids that rot structural timber joists before they are discovered.

Fortunately, upgrading to this authentic McAlpine brass shower trap solves these durability and styling worries completely. Specifically, the heavy solid brass top flange handles heavy footsteps and resists scratching, keeping its premium high-shine finish for years. Additionally, the rock-solid mechanical clamp creates a permanently watertight seal against your 50mm tray hole. Therefore, you get an ultra-reliable, fast-draining, and high-end metal finish built to last a lifetime.
