American Standard Madera 1.1 – 1.6 gpf (4.2 – 6.0 Lpf) Chair Height Top Spud Elongated Bowl - AMS-3043001

No tank. The Madera 3043001 is a floor-mount flushometer bowl with a 1-1/2 inch top spud inlet, so it needs a separate flush valve mounted above the bowl. It also ships less seat, so budget a seat on the order. This is the standard setup in commercial restrooms, schools, and healthcare, where a flushometer handles back-to-back use better than a gravity tank.

Both. The Madera chair height bowl is built for a 10 inch (254 mm) or 12 inch (305 mm) rough-in, so it drops onto the common commercial waste locations without moving the closet flange. Measure from the finished wall to the center of the flange bolts to confirm which one you have.

Anything in the 1.1 to 1.6 gpf (4.2 to 6.0 Lpf) band works. The bowl is a High Efficiency Toilet rated across that whole range and holds a MaP score of 1,000 grams at 1.1 to 1.6 gpf, which is the top of the MaP scale. That means you can spec a 1.28 gpf valve for a water conservation project, or a 1.6 gpf valve to match the rest of a building, using the same bowl.

Match the spud to where your supply comes from. The 3043001 is a top spud bowl, so the flush valve connects on top of the bowl and the supply drops from the wall above, the usual exposed flushometer arrangement. If your supply enters behind the bowl for a concealed valve or a wall carrier setup, a top spud bowl will not connect and you need a back spud model instead. This is a floor-mount bowl either way, not a wall-hung one.

If the existing bowl is a floor-mount top spud flushometer bowl on a 10 or 12 inch rough-in, the 3043001 lands on the same flange and the same 1-1/2 inch spud connection, so the drain and supply stay put. What changes is height: 16-1/2 inches instead of the lower standard bowl, so the flush valve handle sits higher and the seat height on that stall no longer matches the neighboring ones. Worth planning if you are converting a run of stalls one at a time.

White only, part number 3043001.02. That is the number to give a distributor or match against an existing fixture. The bowl is elongated, not round front, so an existing round-front seat will not fit it.

Three things beyond the bowl: a flushometer valve sized for a 1-1/2 inch top spud connection, an open-front elongated commercial seat (the bowl ships less seat), and a wax ring plus closet bolts for the flange. Check whether your flush valve comes with the spud coupling or whether that is separate. Standardizing the seat and valve across a floor keeps the maintenance stock down.

The bowl has a condensation channel built in, which catches and routes the condensate that forms on a flushometer bowl when cold supply water meets warm humid air. It is not a substitute for a tempering valve on a chronically wet job, but it keeps drip off the floor around the base in the ordinary case.
