American Standard Afwall ADA Retrofit 1.28 – 1.6 gpf (4.8 – 6.0 Lpf) Top Spud Elongated Wall-Hung EverClean Bowl - AMS-2294011EC

That is exactly what the American Standard Afwall ADA Retrofit bowl is built to do. It roughs in at a 16-1/8 inch (410 mm) rim height to meet ADA, and it replaces a standard wall-hung 3.5 or 1.6 gpf model with no modification to the existing carrier or the through-wall supply. The one condition: the centerline of the current waste outlet has to be 5-1/4 inch (133 mm) above the finished floor. If your existing outlet sits at that height, the swap is bowl-only.

Neither. It ships as a bowl only, less seat, and without a flushometer. What is in the box is the flush valve rough-in adapter kit, which is what lets it pick up the existing valve location on a retrofit. Budget for an elongated open-front seat and, if you are not reusing the old flushometer, a top spud valve to suit.

A 1-1/2 inch (38 mm) top spud. Top spud means the valve connects down into the top of the bowl rather than behind it, so the flushometer is exposed above the fixture. Any 1-1/2 inch top spud flushometer in the 1.28 to 1.6 gpf range will mate to it.

Either works. The Afwall ADA Retrofit bowl is a High Efficiency Toilet rated across the full 1.28 to 1.6 gpf (4.8 to 6.0 Lpf) band, so you can reuse an existing 1.6 valve today and drop to a 1.28 valve later without changing the bowl. That flexibility matters on a phased fixture upgrade where the valves and bowls are replaced on different schedules.

The Afwall uses a direct-fed siphon jet flush with a 2-1/8 inch (54 mm) fully glazed trapway. Direct-fed means the jet is supplied straight off the valve rather than through a tank, which is why the bowl holds its performance at the low end of the 1.28 gpf range. The glazing through the trapway is what keeps waste from catching on a rough ceramic surface, which is the usual cause of repeat flushing in schools, stadiums and other heavy-use commercial restrooms.

Wall-hung. The Afwall ADA Retrofit bowl carries no load on the floor, so it needs a carrier in the wall chase to support the fixture and take the waste connection. That is why it is a retrofit part: the intended job is replacing a bowl on a carrier that is already in place. If you are building new or there is no carrier in the wall, you need a carrier as well, or a floor-mounted flushometer bowl instead.

It will mount on the same carrier, but it projects further into the room. The bowl measures 26.875 x 17.813 x 15.125 inches, so in a tight toilet compartment check the clear floor space in front of the fixture before you commit, particularly on an ADA stall where the projection eats into the required clearance. The carrier and supply connection are unaffected.

EverClean is an antimicrobial surface fired into the china that inhibits the growth of the bacteria, mold and mildew that cause stains and odors on the fixture surface. It works on the toilet itself, not the room, and it does not substitute for a cleaning schedule. Where it pays off is in facilities fighting recurring odor complaints, since the surface keeps the odor-causing growth down between cleanings for the life of the bowl.

There is one configuration: white, model 2294011EC.020. Standardizing a facility on it is straightforward since there is no finish or trim decision to get wrong on a reorder.

The Afwall has a condensation channel built into the china, which catches and routes the condensate that forms on a cold bowl in a humid room rather than letting it drip onto the floor. It is not a tank toilet, so the usual tank sweating problem does not apply, but the channel is the reason this bowl holds up in humid, poorly conditioned restrooms where dripping fixtures get mistaken for leaks.
