Unique Features and Benefits

Here’s a list of the top 8 features and benefits of the American Standard Champion 4 toilet.

4-Inch Flush Valve

Its wide 4-inch diameter flush valve is one of its best features because it provides plenty of space to flush away all waste. With this feature, you’ll never worry about needing multiple flushes for one bathroom trip.


While this toilet has a 1.6 gallons-per-flush rate, it doesn’t meet EPA WaterSense standards, it still consumes far less water per flush than standard toilets. For example, older model toilets can consume up to 5 gallons per single flush.

EverClean Surface

Its smooth glazed EverClean surface prevents contaminants and bacteria from sticking to the toilet. Thanks to this glaze, your toilet will keep itself cleaner on its own. However, be careful which cleaner you use to avoid damaging the EverClean surface.

Vitreous China Construction

This toile is made from vitreous china – a strong and durable material that is proven to last at least 10 years, making it an excellent long-lasting investment for your bathroom.

Oval Bowl Design

It’s elongated oval toilet bowl design offers a large sitting area that provides superior comfort for people of all sizes. As long as you don’t have a compact bathroom, the elongated toilet bowl is a great option for you.

ADA Compliance

As an ADA compliant toilet, this toilet is easily used by people of all ages as well as people with disabilities. In particular, this comfort height is beneficial for those who have knee trouble when sitting and standing.

2-⅜-inch Trapway

The Champion 4’s large 2-3/8″ (60 mm) inch trapway can move waste that is up to 75% larger than the capacity of standard toilets with 2-inch trapways. Especially when paired with it’s powerful flush, the expanded trapway helps with removing all waste in one flush.




Whereas most toilets today come with a 1-year warranty, the American Standard Champion 4 toilet comes with a 10-year warranty that covers the replacement of damaged or broken parts. This extended warranty offers extended confidence in this model, especially in comparison to other competitor warranties.

Negative Comments

To start, just like the American Standard Cadet 3, this toilet requires a standard 12-inch rough-in for installation. Since the Champion 4 is a one-piece toilet that is heavier than two-piece toilets, you will want an extra pair of hands for its installation. However, the Speed Connect tank/bowl coupling system makes positioning of the tank very convenient, streamlining the installation process.

Here are the main steps to install the Champion 4:

  1. To start, install the bolts in the flange.
  2. Then, install the wax ring and add a sealant around the base.
  3. Next, place the toilet in the correct position and make sure that the bolts enter the right holes.
  4. After placing the toilet, use nuts and washers to secure it in place, ensuring that the toilet is not too tight.
  5. Finally, press down on the flange and connect the water supply.

Overall Rating 4.3/5

This one-piece ADA-compliant toilet offers superior comfort, self-cleaning operation, and a powerful flushing system with siphon action for improved performance. Its glazed EverClean surface prevents the growth of microorganisms, such as mold, mildew, and odor-causing bacteria.

Even though the American Standard Champion 4 is not EPA WaterSense certified, it still saves on water compared to older models. We hope this review was helpful to you.
