American Standard Studio S Concealed Trapway 1.28 gpf/4.8 Lpf Right-Hand Trip Lever Chair Height Elongated Toilet With Slow Close Seat - AMS-226AA105

It is built at Chair Height, American Standard's term for the taller bowl that puts the seat close to a standard chair, and the bowl is elongated. That is the configuration property managers and MRO buyers specify for accessible and senior-friendly restrooms because a taller seat makes sitting and standing easier than a standard-height bowl. American Standard catalogs it as a residential product.

Right hand, and the lever ships in Polished Chrome with the toilet. Handing matters if the tank sits in a tight alcove or beside a vanity where a left lever would be blocked, so check which side is clear before you order. American Standard builds the same Studio S tank in a left hand version, part 4162A104, and the right hand tank alone is 4162A105.

A slow-close seat is included and packed in the same carton as the bowl, and it lifts off without tools for cleaning. You do not order a seat separately. What is not in the box is the wax ring or gasket, closet bolts, and the supply line, so add those to the order if you are not pulling them off the old fixture.

Yes, the Studio S breaks into components. The bowl with seat is 3712A100, the right hand tank is 4162A105, and the left hand tank is 4162A104. That matters when you crack a tank lid or a bowl on a property and only need the broken half replaced, rather than pulling the whole fixture and re-setting it.

An elongated bowl projects roughly two inches further into the room than a round front on the same rough-in. Measure from the finished wall out to whatever is in front of the toilet, the door swing, the vanity, the tub apron. Codes generally want 21 inches of clear floor in front of the bowl and 15 inches from the centerline to any side wall or fixture. In a tight powder room those clearances are what rules an elongated bowl out, not the rough-in.

The outside of the bowl is smooth where a conventional toilet has the trap bulge molded into the side. There is no ribbed channel collecting dust and mop grit, so a housekeeping crew wipes the bowl exterior in one pass. On a fleet of units or a hotel, that is the cleaning labor difference between a concealed trapway and a standard two piece.

White only, manufacturer part 226AA105.020. The 020 suffix is American Standard's white china code, so if you are matching other fixtures in a building already running American Standard white, this is the same color family.

Two things are built in. The PowerWash rim directs water around the bowl to scrub it on every flush, and the EverClean surface inhibits the growth of bacteria, mold and mildew on the glazed china. It reduces how often the bowl needs attention, but it is not a substitute for cleaning, and EverClean acts on the surface, not on the water in the trap.
