Sioux Chief 821-MHP2 – Frequently Asked Questions
1) Will the Sioux Chief 821-MHP2 shower drain base connect to 2 inch PVC drain pipe?
Yes. The 821-MHP2 is a 2 inch trade size PVC base and collar, so it mates to standard 2 inch shower drain piping during rough-in. Body and collar are both PVC, which is what you want below a shower pan in a wet, below-floor location.
2) Does the Sioux Chief 821-MHP2 include the strainer and finish trim?
No. The 821-MHP2 is the base and collar only, the sub-floor foundation of the drain assembly. It accepts the mating strainer and trim hardware, which you order separately and set after the pan and finish work.
3) What is the difference between the Sioux Chief 821-MHP2 shower drain base and the Watco 9300-PVC-CP Innovator shower drain?
The Sioux Chief 821-MHP2 is the rough-in half of the assembly: a 2 inch PVC drain base and collar that solvent-welds to the drain piping under the shower pan, with the strainer and trim set later. The Watco 9300-PVC-CP is an Innovator 9300 series PVC shower drain supplied with a chrome-plated finish surface, so the visible trim comes in the box. If you are plumbing the floor before the pan goes in and will specify the finish strainer separately, the 821-MHP2 is the base you want; if you want the drain and a chrome-plated finish from one part number, the Watco is the one to look at.
4) I need a shower drain with a chrome finished strainer - is the 821-MHP2 the right part?
No. The 821-MHP2 is the PVC base and collar that forms the sub-floor connection point and accepts a mating strainer and trim; the finish strainer is a separate component. For a PVC shower drain that already carries a chrome-plated finish, look at the Watco 9300-PVC-CP from the Innovator 9300 series instead.
5) At what stage of a shower build does the 821-MHP2 drain base get installed?
During rough-in, before the shower pan goes in and before any finish work. The base and collar set the connection point under the pan; the strainer and trim come later once the floor is built up.
6) How many Sioux Chief 821-MHP2 drain bases come in a package?
They ship 25 each per package, which is contractor-case quantity rather than a single unit. Worth knowing if you only need one or two for a single bathroom remodel.
7) Can I use the 821-MHP2 on a remodel, or is it new construction only?
Both. It's used for new construction bathroom rough-in and for remodel or retrofit drain replacement, as long as you can get to the drain line below the pan and you're tying into 2 inch pipe.
8) For stocking shower drain rough-ins on a multi-unit job, does the Sioux Chief 821-MHP2 or the Watco Innovator make more sense?
The 821-MHP2 is built for the rough-in phase - 2 inch PVC base and collar, made in the United States, packed 25 each, so a crew can set floor drains across many units and let the finish trim be chosen later. The Watco 9300-PVC-CP is an Innovator 9300 series PVC drain supplied chrome-plated, which commits the visible finish at the time you buy. Buyers standardizing the underfloor connection across units typically stock the base, while the chrome-plated unit suits openings where the finish is already decided.
9) Is the Sioux Chief 821-MHP2 made in the USA?
Yes, the 821-MHP2 is manufactured in the United States. That matters if you're buying against a domestic-content requirement on a government, healthcare, or education job.
10) Will a PVC shower drain base hold up under a tile shower floor?
PVC is the standard material for below-floor shower drain rough-in because it doesn't corrode in constant wet contact, and the 821-MHP2 uses PVC for both the base and the collar. Solvent-weld PVC joints are also what most 2 inch residential and commercial shower waste lines are already run in, so the materials match.
