  • EASY INSTALLATION: Transform bathroom installations with the Cast Iron Island Tub Drain Rough-in from OS&B. Supplied with all the necessary components to ensure seamless installation, it is the perfect combination of convenience and functionality.
  • LOW-PROFILE DESIGN: Crafted with an asymmetrical deck plate, this tub drain will not interfere with a freestanding faucet rough-in. Easier installation in tight areas: install in an 8"/10" joist space with a 1-1/2"/2" P-trap or slab on grade construction
  • BUILT TO LAST: The tub drain features a cast iron body for durability. Enabling the freestanding tub location to be defined at rough-in (install before tiling), it allows for tub fitting over a finished floor (access below the fixture is not needed).
  • TESTABLE: Built with a snap-off test cap (rated to 30 psi), it enables water, air, and smoke testing. The bathtub drain has a 2" IPT female thread connection, while the epoxy-coated, 18-gauge metal deck flange features holes to lock in thinset.
  • BATHTUB DRAIN KIT: The tub drain rough-in includes a fine-threaded brass tailpiece, a flanged brass tailpiece, an ABS and PVC adapter kit (that helps attach to ABS or PVC bath wastes), a mortar/tile guard, an island drain assembly, and a cutting template.
