Details

Standard replacement waste tops simply don’t have enough thread to catch the underlying trap when dealing with heavy ceramic or deep stone resin shower trays. Consequently, forcing a short-tailed flange can cross the threads or fail to grip entirely, leaving you with an unsealed, dangerously loose drain. Furthermore, if you attempt to use a standard part, water will seep behind the loose flange, leaking straight into floor voids. As a result, you face rotting timber joists and severe water damage on ceilings below.

Fortunately, threading in this authentic McAlpine long tail shower waste top solves this deep tray plumbing challenge perfectly. Specifically, the extended threaded tail is custom-built to span up to 29mm of thick tray material, reaching down to securely clamp your trap body. Additionally, the premium chrome plating updates the look of your shower floor with zero structural modifications. Therefore, you get a solid mechanical connection and a completely watertight seal on extra-deep trays.
