The bonding-flange drain tile setters keep switching to — dreamed up by an installer to beat every other flange on the market. One universal outlet ties into a standard 2" waste pipe or a 3-piece clamping drain with the included adapter, a honeycomb underside bonds into your mud bed like uncoupling, and a woven anti-wicking flange grabs any surface-applied waterproofing. Then the grate carrier and shims dial the grate in horizontally and vertically, so it sets flush — just like a tile. Patent-pending, Made in USA, lifetime warranty.

More Details

FloFX's best-selling square bonding-flange shower drain — a complete, code-certified system for mortar (drypack) shower pans. Verified from FloFX:

  • Universal outlet: Connects directly to a standard 2" waste pipe, or adapts to a 3-piece clamping drain with the included adapter
  • Bonds like uncoupling: Under-flange honeycomb mortar cavities fully embed into the shower base for a rock-solid foundation
  • Waterproofing-ready flange: Woven, anti-wicking Seal Cell fabric bonds to all surface-applied membranes — sheet or liquid
  • Built-in mortar gauge: Seal cells set proper mortar thickness for sheet membranes; the printed surface is a coverage indicator for liquid membranes
  • Grate carrier and shim system: Adjusts the grate horizontally and vertically; the carrier sets like a tile, with a temporary install plate and screwless grate swaps
  • Grate compatibility: Works with ANY FloFX grate, including the Tile-In Grate and Elite Grate Carrier
  • Best for: Mortar (drypack) shower pans and custom bases
  • Material options: PVC or ABS bonding flange
  • Dimensions: 10" × 10" × 2.75"
  • Certified: ICC-ES PMG-1680 / UPC compliant; patent-pending; Made in the USA; backed by a lifetime warranty
  • Also needed: PVC primer + cement (PVC) or ABS cement (ABS), and a waterproofing membrane. If using the clamping adapter, add a 5/16" drill bit and a polyurethane sealant

FloFX Universal Bond Flange Drain Kit — The Installer-Designed Drain That's Winning Over the Trade

Ask a tile setter why they switched to FloFX and you'll hear the same thing: it was designed by one of their own to fix everything annoying about existing bonding flanges. The Universal Bond Flange Kit is the flagship — a square, code-certified drain body built for mortar and custom pans that does three jobs cleanly where other drains make you fight for each one. FloFX calls them Ready to Go, Ready to Roll, and Ready to Flo, and once you've set one, the names make sense.

Ready to Go is the plumbing. One universal outlet connects straight to a standard 2" waste pipe, or adapts to a 3-piece clamping drain using the included adapter — so the same kit covers a new build or a clamp-drain remodel. Underneath, honeycomb mortar cavities embed into the shower base and bond like an uncoupling membrane, while the support structure keeps the flange rigid and flat instead of oil-canning under your mud.

Ready to Roll is the waterproofing. The flange face is a woven, anti-wicking Seal Cell fabric that bonds tenaciously to any surface-applied membrane — sheet or liquid, FloFX's own NoFlo or the system you already run. Seal cells set the correct mortar thickness for sheet membranes, and the printed surface doubles as a visual coverage indicator when you're rolling on a liquid membrane, so you can actually see when you've got full coverage.

Ready to Flo is the part that makes it feel like cheating: the grate carrier and shim set adjusts the grate both horizontally and vertically, so you nail the layout and set the grate dead flush — the carrier literally sets just like a tile. A temporary install plate keeps the opening clean and the grate protected during the pour, and grates swap in and out with no visible screws. It works with any FloFX grate, including the grate install system and the tile-in options. Setting a foam tray instead of a mud pan? Reach for the Traditional Round Bond Flange Kit instead.

Why Tile Pros Choose It

  • Installer-designed: Built by a tile setter to beat existing bonding flanges
  • Universal outlet: 2" waste pipe direct, or a 3-piece clamping drain with the included adapter
  • Bonds like uncoupling: Honeycomb mortar cavities lock into the base
  • Any waterproofing: Anti-wicking flange grips all surface-applied sheet and liquid membranes
  • Dial-in grate: Carrier and shims adjust horizontally and vertically, sets flush like a tile
  • Any FloFX grate: Including the Tile-In Grate and Elite Grate Carrier
  • Code-certified and guaranteed: ICC-ES PMG-1680 / UPC, Made in USA, lifetime warranty
  • The drain your customers notice (in a good way): The grate options alone close the sale

Pro tip: Choose the outlet path before you set — glue straight to the 2" waste for new work, or use the included clamping adapter (5/16" bit plus a polyurethane sealant) over an existing clamp drain. Leave the temporary install plate in through the mud and waterproofing stages so the carrier opening stays clean, and set the grate carrier last, treating it exactly like the surrounding tile for a flush, seamless finish.
