ABS Freestanding Tub Drain Rough-in Kit - Easy ABS Adapter Install

In this review the ABS Freestanding Tub Drain Rough-in Kit is judged as a straightforward, plumber-friendly solution for freestanding and floor-mounted bathtubs. The biggest reason to consider this kit is its focus on compatibility and a clean installation: an ABS adapter is included so the rough-in connects directly to ABS bath wastes, avoiding extra fittings. The kit is presented for people who want a dependable, no-frills drain rough-in that prevents backflow and simplifies testing during installation.

Key Features

• ABS Adapter: The included ABS plastic adapter allows the rough-in to attach directly to ABS bathtub wastes for a quick and clean connection without mixing materials.
• Brass Tail Pipes: The long-lasting brass tail pieces add stability to the drain run and help prevent water backflow and potential odors over time.
• Epoxy-coated Deck Flange: The sturdy 18-gauge metal flange with locking holes and screw fixings secures the tub on wood, cement, tile, or concrete surfaces for stable mounting.
• Test/Dustproof Cap: A snap-off test cap rated to 30 psi enables reliable water, air, and smoke testing of the DWV system before final assembly.
• Protection Cover: A blue protective cover prevents cement and masonry from falling into the drain during installation to keep the waste clean until finished.
• Complete Hardware Pack: The kit ships with tailpieces, nuts, gaskets, screws, anchors, and instructions so installers have the parts needed for most standard installations.

Who It's For

This kit is aimed at plumbers, remodelers, builders, and confident DIYers who need a compatible rough-in for freestanding, floor-mounted, or island tubs and prefer an ABS-to-ABS connection to match the tub waste material. Installers who value a test cap and a sturdy flange will appreciate the inclusion of hardware and the brass tail components.

Those who should look elsewhere are users with tubs that require a PVC-only system or projects needing integrated decorative overflows or finished visible trim pieces; this product focuses on the rough-in and functional plumbing components rather than final visible hardware.

Frequently Asked Questions

Is the drain pipe adapter ABS or PVC?

Can the brass pipe be cut to length on site?
Cutting brass is not recommended because an uneven cut can tear the poly gasket and potentially cause leaks; use the supplied tailpieces as intended.
