American Standard Wall-Hung Toilets

In this post, I will share the difference between the three American Standard wall-hung toilet models. The three models are called the Glenco, the Afwall, and the Instanto. You can see examples of all three on my ILoveVintageToilets videos on youtube.

The Afwall is by far the most common. It has a square back and the flush swirls in a counterclockwise direction. The Afwall has been made since the 1950s and is still made today in a 1.6 gallon per flush model.

The Glenco is a toilet of long ago. It was introduced as American Standard's first wall hung toilet in the 1930s. American Standard retired this toilet in 1978 long before it could be made into a 1.6 gpf model. The Glenco has a bullet shape to it, instead of the square back that the Afwall has. The flush of the Glenco sucks down the water and does not swirl. These toilets were most common in the 1950s and 1960s.

The Instanto is a stadium style toilet with a blowout flush. The flush is similar to the Glenco, however it does not have the bullet shape. The trapway is bigger and it is generally a more industrial toilet. It is still made today but is very rare and reserved for Stadiums and other select buildings.

So there you go, the three American Standard wall hung models. Hopefully you will be able to tell the difference!
