Review: Very smart! - This is a very smart, effective and efficient way to install a vessel tub. I'd use this product again!
Review: Worth the money - We had a customer who bought a fiberglass free standing tub. When we opened it, the tub came with flexible tube that connected to the tub. I did not want to depend on a slip compression joint to hold back any water. So I bought this hoping it would make my life easier. Install was easy. Breaking the tab to get to drain was a little nerve wracking. I had read a lot of reviews that said it broke off, couldn't remove, damaged gasket. I took my time. I used lineman pliers to get it out. I just went slow and wiggled for about 1 minute and it snapped right out. I did have a few little pieces aroind the edge that I thought could damage the gasket. I took my utility knife and just scraped those off. Put the included drain tail piece on the tub, put the plumbers grease on the pipe and slid the tub down. It worked great! Totally worth the money if you cannot access the plumbing from below. I will buy this again.

## Features

- EASY INSTALLATION: Make bathroom remodels simpler with the Two Piece PVC 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 kit will not interfere with a freestanding faucet rough-in. Easier installation in tight areas or small bathrooms: install in an 8"/10" joist space with a 1-1/2"/2" P-trap or slab on grade construction or wooden sub flooring.
- BUILT TO LAST: The tub drain kit features a PVC 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 DESIGN: Built with a snap-off test cap (rated to 30 psi), it enables water, air, and smoke testing. The bathtub drain has a 2" DWV hub connection, while the epoxy-coated, 18-gauge metal deck flange features holes to lock in thinnest.
- FULL BATHTUB DRAIN KIT: This tub drain kit includes a flanged brass tailpiece, a PVC adapter kit (that helps attach to PVC bath wastes), a 2" x 1-1/2" PVC reducing bushing, a mortar/tile guard, an island drain assembly, and a cutting template for the rough-in.
