Comparison: American Standard Champion 4 VS Champion 4 Max Toilet

Last Updated on November 11, 2026

Are you in the market for an American Standard toilet? The one-piece Champion 4 and two-piece Champion 4 Max both use an elongated bowl, a large piston flush valve and a 12-inch rough-in. Their differences matter when you are deciding how high you want to sit, how much water to use and what you need in the box.

This American Standard Champion 4 vs. Champion 4 Max comparison uses the White 2004.314.020 one-piece toilet and the 231AA.104 two-piece Max. The American Standard Champion 4 family includes another one-piece Right Height configuration. Compare the exact model when looking at the rim height or checking which seat comes with the fixture.

The basic water difference is that one uses 1.28 GPF and another 1.6 GPF. In the two configurations compared here, one toilet is a one-piece unit and another is a two-piece unit. If you are deciding which toilet best suits you, compare the rough-in, bowl projection and finished seat height before comparing prices.

More details of the American Standard Champion 4 and Champion 4 Max toilets

American Standard Champion 4 Standard Height Toilet

The 2004.314.020 has a 15-inch ceramic rim and an included slow-close elongated seat. The lower rim can suit users who prefer a shorter sitting height. The integrated tank and bowl give you one less exterior joint to wipe. The trade-off comes during installation, when the whole fixture has to be carried and placed at once.

The gravity flush uses 1.6 gallons. The 4-inch piston-action valve and 2⅜-inch glazed trapway are designed to move water and waste through the bowl. A partial obstruction or a low tank level can still interfere with any flush.

American Standard’s EverClean surface is intended to inhibit the growth of stain- and odor-causing microorganisms on the treated surface. Clean the bowl with products suited to glazed china. The American Standard Titan VS Champion 4 Comparison covers a different pairing from the same brand.

Pros

• One-piece body with no external tank-to-bowl seam.
• Slow-close elongated seat included in the 2004.314.020 package.
• Lower 15-inch rim for users who prefer standard height.
• 4-inch piston valve and 2⅜-inch glazed trapway.

Cons

• The complete fixture is heavier to position than a separate tank and bowl.
• Uses 0.32 gallon more per flush than the 1.28 GPF Max.
• The lower rim can be harder to rise from for some adults.

American Standard Champion 4 Max Right Height Toilet

The 231AA.104 Max has a separate tank and elongated bowl. Its 16½-inch rim puts the ceramic 1½ inches higher than the standard-height Champion 4. The seat adds to both measurements. Before buying for a family bathroom, check who uses the toilet most and whether a higher seat leaves their feet supported.

The Max uses 1.28 gallons through the Champion flush system. Its PowerWash rim directs water around the bowl during the flush. The fixture-only package calls for a separate elongated seat and supply connector. Complete packages in the wider Max range can have different contents, so read the exact model and package description.

The 231AA.104 is a WaterSense configuration and has an EverClean surface. Check the finish suffix if the room already has White, Bone or Linen fixtures. Chrome describes the trip lever finish. The vitreous china color is a separate choice.

Pros

• WaterSense-rated 1.28 GPF flush.
• Right Height elongated bowl with a 16½-inch ceramic rim.
• Tank and bowl can be moved into the room separately.
• PowerWash rim and EverClean surface.

Cons

• Seat is a separate purchase for the 231AA.104 fixture package.
• The tank-to-bowl seam adds a place to clean and a gasket to service.
• Some households will find the lower Champion 4 rim more comfortable.

Installation and Maintenance

Both models use a standard 12-inch rough-in. Measure from the finished wall to the floor-bolt centerline and leave room for the door and shutoff. With the one-piece 2004.314.020, plan the lift and check clearances before setting the toilet on the seal. With the two-piece Max, check the gasket between the tank and bowl and tighten the tank hardware evenly according to the model instructions.

Before removing the old toilet, check where the supply connector bends and where the new bowl meets the floor. A replacement can use the same rough-in and still have a wider tank. With the Max, check that the shutoff can turn freely with the tank installed. With the one-piece model, measure the doorway and check any turns or stairs on the route into the room. Carry the fixture from its base rather than the lever or seat.

If either model refills when no one has flushed it, check the tank waterline and piston seal. A seal and a complete flush-valve assembly are different parts. Record the model from the tank or purchase paperwork before ordering. If the bowl rocks, inspect the mounting and flange seal before adding force to the bolts.

Overall Value

A Max flush uses 20% less water than a 1.6-gallon Champion 4 flush. At 15 flushes a day, the difference is about 1,752 gallons per year. Put your actual flush count into the household toilet water calculator to see how much the difference matters to you. Include a seat and any flange or supply parts in your price comparison.

The water estimate assumes one flush per use and no tank leak. If the old fixture refills on its own, repair the leak before comparing utility bills. A change in the household’s flush count can also affect the result. Count a typical day first, then compare both models at the same number of flushes.

Which is better? American Standard Champion 4 or Champion 4 Max toilet?

Choose the Champion 4 2004.314.020 if you prefer the lower rim, the included seat or the one-piece exterior. Choose the Champion 4 Max 231AA.104 if you want the taller bowl and lower water use. In this American Standard Champion 4 vs. Champion 4 Max comparison, both use a large valve. Fit, rim height and flush volume are the practical reasons to choose.

FAQs

Are both toilets suitable for small bathrooms?

Both examples are elongated and need space for the bowl and the door swing. Check the measurement from the finished wall to the front of the bowl and the width of the tank. Sharing a 12-inch rough-in does not give two toilets the same footprint.

Do these toilets come with a warranty?

American Standard lists a 10-year limited warranty for the two fixture models compared here. Terms can differ on other Champion packages and separately purchased seats. Keep your receipt and the model number for a warranty claim.

Which toilet is more powerful in terms of flushing performance?

Both use a 4-inch flush valve and a 2⅜-inch trapway. Flush volume alone does not tell you which bowl clears more waste. If you compare test scores, match the exact model and look for scores reported under the same conditions.

Are the Champion 4 and Champion 4 Max easy to install?

The one-piece fixture needs to be moved in one lift. The Max can be carried in pieces and requires assembling the tank to the bowl. If the existing flange is damaged or the shutoff needs to move, allow for that repair before installing the new toilet.
