American Standard Edgemere Two-Piece 1.28 gpf/4.8 Lpf Chair-Height Elongated Toilet Less Seat - AMS-204AA104

The Edgemere two-piece elongated toilet sets on a standard 12-inch rough-in, meaning 12 inches from the finished wall to the center of the closet flange bolts. If you're replacing an existing fixture in a building stock with 10-inch or 14-inch rough-ins, measure before you order, because this bowl won't sit right on either one.

Yes. The Edgemere is ADA compliant and meets Americans with Disabilities Act requirements for use and accessibility, with a chair-height bowl that measures 17 inches tall including the seat. One thing to plan for on an ADA job: the toilet ships less seat, and since seat thickness varies, the finished height can shift slightly depending on which seat you pair with it. Note also that American Standard classifies the Edgemere as a residential fixture, so for high-traffic commercial restrooms you may want a commercial-rated bowl instead.

No seat is included. The Edgemere 204AA104 is a less-seat model, so you order an elongated seat separately. Budget for that on every unit if you're buying for a multi-unit turnover, and pick the seat deliberately: the 17-inch chair height quoted for this bowl includes a seat, so a thicker seat raises the finished height slightly.

The Edgemere is a chair-height bowl at 17 inches to the top of the seat, versus roughly 15 inches on a standard-height fixture. Chair height puts the rim closer to a dining chair, so users sit and stand with less drop, which is why it's the height ADA work calls for and why it's the common spec in senior housing and accessible units. Standard height still reads better for children's bathrooms and for matching existing fixtures in a building where everything else is 15 inches.

1.28 gallons per flush, 4.8 liters, and it's WaterSense certified, which means it uses 20 percent less water than a standard 1.6 gpf fixture while performing as well or better. WaterSense certification is the qualifying criterion most municipal and utility toilet-rebate programs run on, so a 1.28 gpf swap across a portfolio is the usual path to those credits.

The Edgemere runs a fully glazed 2-inch trapway, which helps prevent clogs, and flushes off a 3-inch flapper valve. The 3-inch valve dumps the tank faster than the older 2-inch flappers, which is what gets a 1.28 gpf bowl to clear a full load, and the glazing on the trapway keeps waste moving through the bend rather than catching on raw china. Those two specs together are the ones to look at when you're picking a low-flow toilet for a property where you don't want service calls.

American Standard part number 204AA104.020 is the one to specify. It's the Edgemere two-piece, 1.28 gpf, chair-height elongated bowl, less seat, and it's built in white only, which is the .020 suffix American Standard uses for white china. If you're standardizing fixtures across a building, that single number covers the whole order.

An elongated bowl like the Edgemere projects roughly two inches further off the wall than a round-front bowl of the same rough-in. In a full bath or an accessible stall that's usually the better bowl, and it's what ADA work generally specs. In a tight powder room or a unit where the door swing or a vanity crowds the fixture, measure your clear floor space in front of the flange first; that's where an elongated swap goes wrong. The rough-in itself is unchanged at 12 inches either way.

Beyond the toilet itself, plan on an elongated seat (not included), a wax ring or waxless gasket, closet bolts, and a supply line with a stop. Two-piece toilets ship as a separate bowl and tank, so the tank-to-bowl bolt kit and gasket typically come in the carton with the tank hardware, but the seat is the item people forget most often on a less-seat model.

Vitreous china, the glazed, fired ceramic that essentially every commercial and residential toilet body is made from. It's non-porous once glazed, so it doesn't absorb waste or odor and it cleans with ordinary bathroom chemicals. The practical failure point on a fixture like this isn't the china, it's the tank trim, so keep the flapper and fill valve on your parts shelf if you're maintaining a lot of them.
