Sioux Chief 821-2A-3 Membrane-Compatible ABS Shower Pan Drain, Selectable Strainer Finish

The Sioux Chief 821-2A-3 is an ABS-bodied shower pan drain engineered for tile-floor shower installations that incorporate a waterproofing membrane. The drain body is molded from ABS plastic and features a beveled design with pre-located mounting holes that simplify subfloor installation for the rough-in plumber. This family is available with a choice of finished strainer head, selectable across Square Chrome-Plated Head, Square Oil-Rubbed Bronze, and Stainless Steel Screw-In Strainer finishes, so installers can match the trim to the job. Regardless of the strainer head selected, the ABS rough-in body, beveled design, and membrane-compatible construction remain the same, letting contractors standardize on one rough-in part while selecting the finish that fits the project at trim-out.

Key Features

  • Durable Construction: ABS plastic drain body provides a lightweight, corrosion-resistant base for subfloor mounting.
  • Beveled Body Design: The beveled drain body and pre-located mounting holes allow for easy, accurate installation into the subfloor before the finished shower surface is applied.
  • Membrane-Compatible Application: Engineered for use in tile-floor showers that incorporate a waterproofing membrane, helping the installer tie the drain assembly into the membrane system during rough-in.
  • Selectable Strainer Head Finish: Available across Square Chrome-Plated Head, Square Oil-Rubbed Bronze, and Stainless Steel Screw-In Strainer options, giving installers a finished look to match the bathroom design while using the same rough-in body.
  • Integral Strainer: Each finished head option includes a cast or formed strainer to catch debris at the shower floor surface.
  • Packaging: Supplied 5 EA per package for distributor and contractor stocking.

Sioux Chief 821-2AQCP – Frequently Asked Questions

1) Is the Sioux Chief 821-2A shower drain made for a membrane shower pan or for a mud-set tile floor without membrane?
The 821-2A is built for tile-floor showers that use a waterproofing membrane. The ABS body ties into the membrane system during rough-in, and the beveled body with pre-located mounting holes screws down to the subfloor before the finished floor goes in. If your floor assembly has no membrane to clamp or bond to, this is not the drain for that method.
2) What is the closest alternative to the Sioux Chief 821-2A shower pan drain if I need a PVC body instead of ABS?
The Sioux Chief 821-2A shower pan drain uses an ABS plastic body, so it is solvent-welded with ABS cement. If the shower waste line on the job is PVC, the Watco 9300-PVC-CP Innovator shower drain is the comparable choice, with a PVC body and a chrome-plated finish from the Innovator 9300 series. Match the drain body material to the drain line material so the solvent weld is a like-to-like joint rather than a transition fitting.
3) Is the body of the Sioux Chief 821-2A drain plastic or metal, and will it corrode in a shower?
The drain body is molded ABS plastic, which is corrosion resistant and light to handle on the subfloor. The visible strainer head is cast metal with a finish applied (chrome-plated or oil-rubbed bronze depending on the model), or stainless steel on the screw-in version.
4) Can I install the Sioux Chief 821-2A square drain and tile over it later, or does the head go in at rough-in?
The body goes in at rough-in. It mounts to the subfloor through the pre-located holes in the beveled body, gets tied into the membrane, then the tile floor is set over it. The cast strainer head is the finished piece that lands at the shower floor surface at the end of the job, so the ORB or chrome head is not exposed to the rough-in work.
5) Can I use the Watco Innovator 9300-PVC-CP if I want an oil-rubbed bronze strainer head?
No. The Watco 9300-PVC-CP Innovator is supplied chrome-plated. For an oil-rubbed bronze finished strainer, use the Sioux Chief 821-2AQRB, which carries a square cast head in an oil-rubbed bronze finish over the ABS membrane-style drain body. Sioux Chief also offers the same body with a square chrome-plated head as the 821-2AQCP and with a stainless steel screw-in strainer as the 821-2A.
6) I need a chrome shower drain for a tile shower pan - how does the Sioux Chief 821-2AQCP compare to the Watco Innovator 9300-PVC-CP?
Both give you a chrome-plated finished appearance at the shower floor. The Sioux Chief 821-2AQCP pairs an ABS drain body with a square chrome-plated cast head, and the body is beveled with pre-located mounting holes for fastening into the subfloor on tile-floor showers built over a waterproofing membrane. The Watco 9300-PVC-CP Innovator is a PVC-bodied chrome-plated shower drain. The practical decision points are body material against your waste piping and whether you want the square head profile the Sioux Chief carries.
7) How many Sioux Chief 821-2A shower drains come in a package?
They ship 5 each per package, which is why it is a common stocking item for distributors and plumbing contractors running multiple bathrooms.
8) Is the Sioux Chief 821-2A drain acceptable for commercial bathroom work or residential only?
It is used in both. Sioux Chief lists it for residential and commercial bathroom rough-in, as well as renovation and new-construction shower floor drainage, which is why property managers and contractors standardize on it across multi-unit tile shower work.
