Details

Large plastic shower grids frequently flex, crack underfoot, or suffer from finish degradation caused by harsh chemical bleach cleaners. Consequently, a scuffed or discoloured plastic drain top quickly ruins the look of an otherwise high-end shower enclosure. Furthermore, many homeowners think that switching to a premium metal fitting requires lifting the entire shower tray or cutting open floorboards. As a result, they tolerate a broken drain or face a messy, expensive bathroom modification.

Fortunately, installing this authentic McAlpine brass shower waste top solves these durability and styling issues instantly. Specifically, the standard 1.5″ threaded tail lets you simply unscrew your damaged plastic flange from inside the tray and twist this heavy-duty brass unit straight into place. Additionally, its solid metal build won’t warp or tarnish over time, maintaining a pristine mirror shine. Therefore, you get a quick, tool-free luxury upgrade built to handle a lifetime of daily use.
