American Standard Cadet PRO Two-Piece 1.28 gpf/4.8 Lpf Chair Height Round Front 10-Inch Rough Toilet Less Seat - AMS-215BB104

That's exactly what the Cadet PRO 215BB104 is built for. It's a 10-inch rough-in bowl, meaning the closet flange centerline sits 10 inches off the finished wall rather than the usual 12. Measure from the finished wall (not the baseboard) to the center of the flange bolts before you order. If that measurement comes back at 12 inches, this is the wrong bowl and you want the 12-inch rough version of the Cadet PRO instead.

No seat is included. The 215BB104 ships less seat, so you need to order a round front seat separately. It does come with the color-matched bowl caps and a metal trip lever, so the only thing missing to finish the install is the seat and your supply line and wax ring.

The Cadet PRO 215BB104 is stated ADA compliant and chair height, measuring 17 inches tall including the seat. Since the seat is sold separately, your finished height shifts slightly with whichever seat you install. One caution for spec work: American Standard lists this model as a residential product, so if you are writing it into a commercial or institutional job, confirm it satisfies the fixture schedule for that occupancy.

It's WaterSense certified at 1.28 gallons per flush (4.8 liters), which is 20 percent below the 1.6 gpf federal maximum. That's the threshold most utility rebate programs and green building credits key on, so the flush rate is the number to put on the submittal.

Round front, which is what the Cadet PRO 215BB104 is, saves roughly two inches of projection into the room compared to an elongated bowl. In a tight half bath, a narrow powder room, or anywhere the door swing clips the fixture, that's the difference between a comfortable install and a knee-to-door situation. Elongated is the more comfortable seat where you have the floor space. Pair the round front decision with the 10-inch rough-in and you're covering the two most common tight-space problems at once.

The 215BB104 uses what American Standard calls a trade exclusive tank, sold through wholesale channels rather than retail. Practically, that means the fill valve and flush valve are the trade line rather than the big-box version, so match parts by the 215BB104 model number rather than by a generic Cadet part. The fill valve has a metal shank and the trip lever is metal, not plastic, which is the durability difference property managers usually care about on a fleet of units.

It's vitreous china with metal internals where the cheap units use plastic, specifically a metal trip lever and a metal shank fill valve, which are the two parts that fail first in high-turnover units. The PowerWash rim scrubs the bowl on each flush, which cuts the cleaning burden between tenants. Being a two-piece, the tank and bowl ship and carry separately, which matters on stair walk-ups.
