American Standard Champion 4: Review


american standard champion 4 reviewThe Champion 4 is a one-piece toilet and cistern combined. It is made of vitreous china with an Ever Clean Surface. The Ever Clean finish is specially designed to reduce staining and inhibit the growth of mold, bacteria, and mildew. Therefore, the toilet’s finish leads to reducing the cleaning requirements.

A combination of the levered flush mechanism, the shape of the bowl, and the height of the seat all make the Champion 4 ADA compliant.

Flushing System

One of the best flushing toilets has a single flush that uses American Standard’s Champion 4 flushing system. There is a 4” non-adjustable piston that, with the Accelerator flush valve, delivers a high pressure 1.6 gallons flush. The 2 3/8” trap way has full glaze to allow a smooth passage of waste to the drainage system. The flush system has been tested as capable of removing 2.2 lbs. of waste in a single flush.


The high-pressure flushing system, with a combination of the Ever Clean surface of the bowl, helps ensure that this toilet flushes completely the first time. The Ever Clean surface, in addition, prevents the buildup of stains and discoloration due to mildew, microbial, and bacterial action.


The 1.6 gallons per flush ensures that this toilet is within Federal toilet flush specifications. However, the 1.6 gpf means that it is outside the Water Sense guidelines and does not qualify for rebates.

Ease of Installation

The toilet is designed to fit a minimum of a 12” rough in. As the Champion 4 is a one-piece toilet, it is heavier than the individual parts of a two-piece. Therefore, this weight makes it a little more difficult to position it over the rough out. So, it is better done as a two-person job, rather than on your own. Apart from that one small thing, the toilet is a simple straightforward, and very quick installation. Secure to the floor and attach the water supply, then fit the seat, and finally, the toilet installation is complete.
