American Standard Madera 1.1 – 1.6 gpf (4.2 – 6.0 Lpf) 15" Height Top Spud Elongated Bowl - AMS-2234001

No tank. The Madera 2234001 is a floor-mounted flushometer bowl, so it needs a flush valve (flushometer) supplied separately, piped to the 1-1/2 inch top inlet spud. It also ships less seat, so budget for a seat as well.

It fits a 10 inch (254 mm) or 12 inch (305 mm) rough-in, which covers the two standard waste centerline dimensions on commercial floor-mount installs. Measure from the finished wall to the center of the closet flange before ordering.

Yes. The bowl is rated to operate anywhere from 1.1 to 1.6 gpf (4.2 to 6.0 Lpf), so a 1.28 gpf valve is inside its range. That band lets a facility standardize on one bowl and change flush volume by swapping the flushometer.

On the Madera 2234001 the flush valve connects at the top of the bowl, so the flushometer runs down the wall and into the spud from above. A back spud bowl takes the supply through the wall into the rear of the bowl and is used where the flush valve is concealed behind the wall. Pick the one that matches the existing piping, since the two are not interchangeable.

The Madera bowl carries a MaP score of 1,000 grams at 1.1 to 1.6 gpf, which is the top of the MaP test scale, and uses a 2-1/8 inch (54 mm) fully glazed trapway with direct-fed siphon jet action. That combination is what high-traffic commercial restrooms are specified on.

An elongated seat. The bowl is elongated and ships less seat, so the seat is a separate line item; open-front commercial seats are the usual choice for public restrooms on a flushometer bowl.

It includes a condensation channel, which collects and redirects moisture forming on the china so it does not drip onto the floor. That matters in unconditioned or high-humidity restrooms where puddling under the fixture is a slip and maintenance issue.

It is sold in white, ordered as American Standard part number 2234001.02.
