Solve my headache! Easy to use and great quality. Cost a little but totally worth it. 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ETP6XNY | | Best Sellers Rank | #51,076 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #78 in Bathtub Drains | | Brand | OS&B | | Brand Name | OS&B | | Color | Red & Black | | Customer Reviews | 4.7 out of 5 stars 711 Reviews | | Global Trade Identification Number | 00775439064557 | | Included Components | PVC FREESTANDING BATHTUB DRAIN | | Item Type Name | ITD5135 | | Item Weight | 16 ounces | | Manufacturer | OS&B | | Material | Brass | | Material Type | Brass | | Maximum Pressure | 30 psi | | Outside Diameter | 2 inches | | UPC | 775439064557 | | Unit Count | 1 Count | ## Product Details - **Brand:** OS&B - **Color:** Red & Black - **Finish Type:** PVC - **Installation Type:** Freestanding - **Item Weight:** 1 Pounds - **Material:** Brass - **Product Dimensions:** 11"L x 11"W x 4"H - **Shape:** Round - **Style:** ITD5135 - PVC - **UPC:** 775439064557 ## Images ![ITD5135 2-Piece PVC Island Tub Drain Rough-In Kit for 8/10-Inch Joists - Image 1](https://m.media-amazon.com/images/I/61k87nZoVeL.jpg) ![ITD5135 2-Piece PVC Island Tub Drain Rough-In Kit for 8/10-Inch Joists - Image 2](https://m.media-amazon.com/images/I/71-WiN-8eGL.jpg) ![ITD5135 2-Piece PVC Island Tub Drain Rough-In Kit for 8/10-Inch Joists - Image 3](https://m.media-amazon.com/images/I/71aLbRCcWjL.jpg) ![ITD5135 2-Piece PVC Island Tub Drain Rough-In Kit for 8/10-Inch Joists - Image 4](https://m.media-amazon.com/images/I/71RJwljRQDL.jpg) ![ITD5135 2-Piece PVC Island Tub Drain Rough-In Kit for 8/10-Inch Joists - Image 5](https://m.media-amazon.com/images/I/71J6vTAiSlL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Quality and Worth the money! *by L***O on November 28, 2025* This is a must have item for free standing tub.

Just figure out where your drain will be, cut a six inch round hole in the sub-floor and screw this to the sub-floor. Put in your flooring material (in my case, cement board and tile). Hook up your drain lines underneath and you are ready to install the tub. With one person helping, we attached the tub tailpiece, lifted the tub up and slid the tailpiece into the drain. The kit is funnel shaped so it guided the tailpiece and tub right in place. The beautiful thing is that if I ever need to take the tub out for any reason there is no reason to tear out the ceiling below to unhook anything, the tub just lifts right out and can be put right back in. Everything was included. The drain kit, solid brass tailpiece and all the connectors and adapters necessary to hook this to my PVC drain lines. I'd definitely buy this again and recommend it to anyone installing a freestanding tub. ## Frequently Bought Together - OS&B ITD5135 PVC Island Tub Drain Rough-in for Freestanding Bathtub, Simplifies Installation, Water, Air, and Smoke Testable Tub Drain, Designed for 8"/10" Joist Space, Plumbing Supplies - DURATECH Inside Pipe Cutter with 2 Replaced Blades, for PVC and Plastic Pipe - Inside Pipe Cutter for PVC Pipe Cutter Tool with Adjustable Depth Gauge Guide, 5pcs Saw Tooth Blades with 0.315Inch Hex Key Shaft, Plumbing Internal Plastic Pipe Cutter Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/30211107-itd5135-2-piece-pvc-island-tub-drain-rough-in-kit](https://www.desertcart.hr/products/30211107-itd5135-2-piece-pvc-island-tub-drain-rough-in-kit) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-02*
