American Standard Madera 1.0 - 1.6 gpf (3.8 - 6.0 Lpf) 15" Height Top Spud Elongated EverClean Bowl - AMS-3451001

The Madera top spud elongated bowl ships as a bowl only. It's built to pair with the American Standard Ultima Selectronic Exposed Toilet Flush Valve rated 1.0 gpf to 1.6 gpf (3.8 to 6.0 Lpf), which is sold separately. Budget for the valve and its supply on every fixture when you're pricing out a restroom.

Rough-in is 10 inches (254 mm) or 12 inches (305 mm). Measure from the finished wall to the center of the closet flange before you order, because that dimension is fixed by the existing waste line in a retrofit and there's no adjusting the bowl to cover a mismatch.

No. The Madera 3451001 sits at a 15 inch (381 mm) rim height, which is the standard bowl height, not the taller chair-height bowl used for accessible stalls. If the stall has to meet accessibility height, specify a right-height Madera bowl instead and keep this one for the standard stalls.

The inlet spud is 1-1/2 inches (38 mm), top spud, so the flush valve comes down to the top of the bowl rather than back to the wall behind it. That's the standard commercial 1-1/2 inch connection, so a 1-1/2 inch flush valve vacuum breaker and spud coupling will land on it.

The bowl is rated across 1.0 to 1.6 gpf (3.8 to 6.0 Lpf), so a 1.28 gpf valve is inside its range. Flush performance shifts with the valve you pick: paired at 1.1 to 1.6 gpf it hits a MaP score of 1,000 grams, and at 1.0 gpf it comes in at 800 grams. In a high traffic public restroom that spread is the argument for staying at 1.28 or 1.6 rather than going down to 1.0.

The trapway is 2-1/8 inches (54 mm) and fully glazed, with a 2 inch (51 mm) minimum ballpass, and the flush is a direct-fed siphon jet. The full glaze plus that ballpass is what carries paper through in a school, stadium, or facility restroom instead of catching it. Combined with a 1.1 to 1.6 gpf valve it scores 1,000 grams on MaP.

Top spud means the flush valve pipe drops onto the top rear of the bowl and stays exposed in the stall. That works where the valve is surface mounted on the wall, which is what the matching Ultima Selectronic Exposed valve is. If the building hides the carrier and valve behind a chase and the supply comes through the back wall, you want a back spud bowl instead, not this one.

EverClean is an antimicrobial surface fired into the china that inhibits growth of stain- and odor-causing bacteria, mold, and mildew. It slows down staining and odor between cleanings, which is why it shows up in high-turnover restrooms, but it doesn't sanitize the fixture and your janitorial schedule doesn't change.

White only, MPN 3451001.02. If you're standardizing a facility on white commercial china, this one matches straight across; there is no other color on this bowl to specify.
