American Standard Colony3 Chair-Height Elongated Bowl - AMS-3437A101

Bowl only. The Colony3 chair-height elongated bowl ships without a tank and without a seat, so both have to be ordered separately to make a complete two-piece toilet. Color-matched bowl caps are included, so you don't need to source those. When you pair a tank to it, match the Colony3 two-piece tank in the same white finish so the china color lines up.

The rim sits at 16-1/2 inches, which is what American Standard calls chair height and what most people mean by comfort height: a seated position closer to a dining chair than a standard bowl. Add a seat on top and the finished sitting surface lands a little higher again. For senior housing, accessible units, or any property manager standardizing on taller fixtures, that 16-1/2 inch rim is the number that matters.

The bowl measures 27.938 inches long, 15.125 inches wide, and 17.563 inches high. In a tight powder room or a compartment stall, the length is the number to check first, since an elongated bowl projects further into the room than a round front. Measure from the finished wall behind the bowl out to the door swing or the opposite fixture before you commit to elongated.

Elongated bowls like the Colony3 3437A101 give more seating surface and are what most tenants expect in a renovated unit, but they run longer front to back, 27.938 inches here. Round front is the choice when the room is short and you'd otherwise block the door swing or crowd a vanity. If you have the floor depth, elongated plus the 16-1/2 inch chair height is the combination that reads as an upgraded bathroom without changing the rough-in.

The trapway is 2 inches and fully glazed, which is the detail that matters for turnover properties: the glaze gives waste a smooth path instead of a rough china surface to catch on. Combined with the elongated bowl, it's a builder-grade fixture aimed at volume residential and multi-family work rather than a light-duty replacement.

Yes, if the china cracked but the tank is sound. The 3437A101 is sold as a bowl on its own and belongs to the Colony family, so it's the part to order when you're replacing a broken bowl rather than the whole fixture. Confirm your existing tank is a Colony three-bolt two-piece tank before ordering, since a bowl swap only works when the tank mounting pattern and the sanitary bar match.

White only, ordered as MPN 3437A101.020, and the .020 suffix is American Standard's white color code. The bowl caps that come with it are color matched to the same white, so a replacement in an existing white Colony bathroom group will blend with the tank and any matching lavatory.

It's a raised shelf on the back of the bowl where the tank sits, and it closes off the gap that normally collects dust and grime under a two-piece tank. For janitorial and MRO crews cleaning dozens of fixtures, it removes one of the spots that otherwise needs a rag worked in behind the tank.
