The 1916 Collection Universal Freestanding Tub Drain removes the guesswork and complexity from installing freestanding or island tubs. Simply install the gasketed drain receptor to the 1-1/2” (or 2” using supplied adaptor) DWV system at rough-in. This super-compact drain body with its asymmetrical coated Stainless Steel flange, can be installed in tight spaces, through a 4” hole in the subfloor into an 8” joist.
