Details

Over time, constant foot traffic and bathroom cleaners cause wide plastic shower grids to scratch, yellow, or crack. Consequently, the entire shower tray looks old, dated, and unhygienic. Furthermore, many homeowners assume that replacing a damaged wide waste top requires cutting through the floorboards to replace the entire underlying plumbing system. As a result, people end up putting off the repair or paying hundreds of pounds for an unnecessary, messy plumbing job.

Fortunately, screwing in this authentic McAlpine white shower waste top solves this aesthetic and costly dilemma in less than two minutes. Specifically, the standard 1.5″ threaded tail allows you to simply unscrew your old, ruined 85mm flange from above and twist this fresh one straight into place. Additionally, the clean white finish instantly restores a uniform, factory-fresh look to your enclosure with zero tools required. Therefore, you get a quick, cheap upgrade that makes your shower look brand new again.
