Cascena Shower Drain Base Flange — 2″ or 3″ PVC, cUPC

A tile-in drain is only as good as the connection underneath it. The Cascena shower drain base flange bolts down over the waterproofing with a four-bolt clamping ring and gives the drain body a solid, threaded landing in the mortar bed. The body is PVC and the assembly is cUPC certified. The outlet is dual-fit — it seats inside 2″ pipe or over 3″ pipe — so it ties into either rough-in without a separate reducer. Choose the version with the rubber coupling for a gasketed, no-hub connection, or the bare flange if you're solvent-welding direct. Pairs with the Cascena square and linear shower drains, which thread into the flange through their included 2″ adaptor.
