American Standard Studio S Skirted Two-Piece 1.28 gpf/4.8 Lpf Chair Height Elongated Toilet With Seat - AMS-226AA104

It sets on a standard 12 inch rough-in, 305 mm from the finished wall to the center of the closet flange. If your existing waste line measures 10 or 14 inches, this bowl will not sit correctly and you need a different rough-in model.

A slow-close, easy lift-off seat ships with the toilet and is packed in the bowl carton. No separate seat purchase is needed. The lift-off feature matters on rental turns and multi-family cleaning schedules since the seat comes off without tools for a full wipe of the hinge area.

A left hand trip lever in Polished Chrome is included with the toilet. Matte Black and Brushed Nickel levers exist for the same tank and are sold separately if you are matching other trim in the room. If the layout needs the handle on the right, the right hand tank is a different part (4162A105) rather than a lever swap.

Yes, the combination breaks into components: left hand tank 4162A104, right hand tank 4162A105, and the bowl with seat 3712A100. Useful if you cracked one piece and want to keep the matching china rather than replace the whole fixture.

It is WaterSense certified and flushes at 1.28 gpf (4.8 Lpf), which is the high efficiency threshold rather than the 1.6 gpf standard. That is the figure most municipal rebate programs and green building specs ask for.

The bowl is built at American Standard's Chair Height, which puts the seat at the same general height as a standard chair rather than a low standard bowl. That is what most property managers and remodelers are after when they ask for comfort height seating in a unit turn or an accessible-friendly bath. The bowl is elongated rather than round front.

A skirted trapway means the outside of the bowl is a smooth continuous surface instead of the contoured trap bulge, so there is no channel behind the bowl collecting dust and cleaner. The tradeoff is the mounting: skirted bowls anchor differently than a conventional two-piece, so plan on following American Standard's bracket method rather than dropping it straight onto exposed closet bolts.

This one is classified as a residential fixture in the Studio S family, and it is positioned in American Standard's luxury line. It suits apartments, condos, hotel guest baths and single-family remodels. For a high-traffic public restroom, a commercial-rated flushometer bowl is the better direction.

The bowl uses a PowerWash rim that directs water around the full inner surface on every flush, which is how the 1.28 gpf volume covers the same ground a higher-volume rim would. The china also carries American Standard's EverClean surface, which inhibits growth of bacteria, mold and mildew on the glaze, so the bowl stays cleaner between services.

White is the finish offered, ordered under part number 226AA104.020. The .020 suffix is American Standard's white china code, so if you are standardizing a building on white fixtures this matches the rest of the line.
