American Standard Champion Pro vs Champion 4 Comparison

American Standard has long been one of the most recognized and trusted brands in the plumbing fixture industry. The company offers a range of high-efficiency toilets designed to suit different needs and budgets. Two of their most popular models are the Champion Pro and Champion 4 toilets.

The Champion Pro represents American Standard’s newest innovation in toilet flushing technology. It uses a 4-inch piston action accelerator flush valve to deliver a faster, more powerful flush than a standard 2-inch flapper. The Champion 4 uses a more traditional flapper flush valve but still provides excellent waste removal in a water-efficient design.

Deciding between the Champion Pro and Champion 4 largely depends on your priorities in a toilet. Performance, design, ease of installation, and price point vary between the two models. This article will compare the key specifications and features of the Champion Pro and Champion 4 to help you determine the better choice for your bathroom.

The biggest performance distinction between the Champion Pro and Champion 4 lies in the flushing power and efficiency.

Flushing Power

The accelerated flush valve and increased water flow on the Champion Pro provide it with faster, superior flushing capability compared to the Champion 4. The Champion Pro completely evacuates the bowl in just one flush, even removing difficult waste and minimizing streaking. Some reviewers indicate the Champion 4 may occasionally require two flushes to fully clear waste from the bowl.

Waste Removal

The Champion Pro’s increased flush pressure results in 20% better waste removal on each flush according to Maximum Performance testing. This means the Champions Pro provides a cleaner bowl after every use.

Clog Resistance

The Champion Pro’s 4″ valve opening and faster flush make it much more difficult to clog compared to a standard flapper flush toilet like the Champion 4. The larger flush valve on the Champion Pro resists obstructions, allowing the full volume of water to pass through with each flush.

Noise Level

Some users note the Champion Pro has a slightly louder flush noise than the Champion 4 due to the more powerful piston action. However, neither toilet produces an excessively loud or disruptive noise during flushing.

Water Savings

Both the Champion Pro and Champion 4 offer significant water savings by using just 1.6 gallons per flush. This makes them ideal choices for eco-conscious homeowners looking to reduce their environmental impact and water usage.


The Champion Pro and Champion 4 share a few design similarities but also have some noticeable differences:

Bowl Shape

As noted above in the specifications, the Champion Pro bowl is elongated while the Champion 4 offers both elongated and round front bowl options. Elongated bowls provide more comfortable seating position for most adults.

Tank Lever

The chrome tank levers on each model have different styles. The Champion Pro has a curved, slope-front lever while the Champion 4 has a more angular, flat front tank lever design. This gives the models slightly different aesthetics.

Toilet Seat Options

The Champion Pro only comes with an elongated slow-close toilet seat in white. The Champion 4 gives you color options for the seat, like black, white, or bone, and allows you to 

choose between round or elongated.


Both models come in the American Standard colors of White, Linen, and Bone to suit any bathroom decor. The finishes help resist chips, scratches, and staining over time.

Ease of Installation

American Standard designed both the Champion Pro and Champion 4 for easy installation and replacement of old toilets.


The common 12″ rough-in for both models accommodates the majority of residential bathroom toilet installations.

Bowl to Floor Height

The Champion 4 sits about an inch taller off the floor than the Champion Pro. It has an ADA compliant bowl height of 16-1/2” from floor to bowl rim.

Wax Ring vs Gasket

The Champion Pro comes with an Easy Install gasket that seals the toilet to the floor flange with just hand tightening. The Champion 4 uses a standard wax ring for sealing.

Additional Parts

No additional parts, hardware, or specialty tools are required to install either toilet. All parts are included. The gasket and bolts allow for quick tool-free installation of the Champion Pro.


As American Standard’s newest premier toilet, the Champion Pro does come at a higher price point than the Champion 4.


  • Champion Pro: $320
  • Champion 4: $290

Average Retail Price

  • Champion Pro: $235 – $270
