"This 32"" x 60"" gloss white acrylic shower base with a right-side drain offers a sleek, low-profile look and is made for single-threshold 3-wall alcove installations. Assembled dimensions are 60"" L x 32"" W x 3"" H and the durable, rigid construction prevents flexing while allowing quick, reliable installation. The drain opening fits standard 3.5"" compression fitted drains and the unit is CUPC certified, with exact drain placement shown on the technical drawing and the drain sold separately. Professional installation is required and the base is designed for direct-to-stud installation prior to backerboard or cement board for best long-lasting results."
