Champion is American Standard’s line built around a large 4-inch flush valve and a 2-3/8-inch trapway. The choice within the line comes down to one-piece or two-piece, elongated or round bowl, standard or Right Height (American Standard’s name for chair height), and 1.6 or 1.28 gallons per flush.
Champion 4 2034.314: one-piece, Right Height
Choose the Champion 4 2034.314 for a one-piece, chair-height elongated toilet with a seat in the box. American Standard’s spec sheet (lixil.cdn.celum.cloud) lists vitreous china, an EverClean surface that it says inhibits the growth of stain- and odor-causing bacteria, mold and mildew on the surface, 1.6 gpf, the Champion 4 flushing system, a 4-inch piston-action Accelerator flush valve, a 16-1/2-inch rim height for accessible applications, an elongated siphon-action jetted bowl, a 2-3/8-inch fully glazed trapway, a chrome trip lever, bolt caps, a slow-close seat and a 10-year warranty.
It measures 29-3/4 × 17-3/4 × 29-1/2 inches and is designed for a 12-inch minimum rough-in. The supply is not included. The sheet says it meets ADA guidelines when installed accordingly, with the seat top 17 to 19 inches from the floor.

Champion 4 2004.314: one-piece, standard height
Choose the Champion 4 2004.314 for the same one-piece toilet at standard height. American Standard’s spec sheet (lixil.cdn.celum.cloud) lists the same vitreous china, EverClean surface, 1.6 gpf Champion 4 flushing system, 4-inch Accelerator flush valve, elongated jetted bowl, 2-3/8-inch trapway, chrome trip lever, slow-close seat and 10-year warranty as the 2034.314, with a 15-inch rim height. It measures 29-3/4 × 17-3/4 × 28-1/8 inches and roughs in at 12 inches minimum.
One small difference between the two Champion 4 sheets: the 2034.314 sheet calls the flush valve non-adjustable, while the 2004.314 sheet calls it self-closing. Both are listed as 4-inch piston-action Accelerator valves.

American Standard’s spec sheet (lixil.cdn.celum.cloud) lists a two-piece vitreous china toilet with the Champion flushing system, 1.28 gpf (it says 20% less water), WaterSense certification, a PowerWash rim, a metal trip lever and metal-shank fill valve, EZ-Install tools with color-matched bowl caps, an EverClean surface, a 4-inch Accelerator flush valve, a 2-3/8-inch trapway, a 16-1/2-inch rim height, a 12-inch rough-in, a 9 × 8-inch water surface and a 10-year warranty.

Product page: Champion PRO round front toilet (americanstandard-us.com).
One-piece or two-piece, round or elongated
A one-piece toilet has no tank-to-bowl joint to clean or reseal; a two-piece is two parts bolted together. A round-front bowl is shorter front to back. The Champion PRO round is 28-1/4 inches deep; the elongated Champion 4 models are 29-3/4 inches. Our round vs elongated guide and one-piece vs two-piece guide explain the trade-offs.
Height matters for comfort and accessibility. American Standard lists 16-1/2-inch rims on the Right Height models and 15 inches on the standard 2004.314; our comfort height vs standard guide covers who benefits from each.
Colors, trip levers and tank options
The Champion 4 sheets list white, bone and linen, with the chrome trip lever supplied and optional white, polished brass or satin levers (part 738772). The Champion PRO sheet lists white, bone, linen and black, and a 211BA.105 version with the trip lever on the right-hand side.
The Champion PRO tank is also sold in versions for specific needs: 4225A.154 with an Aquaguard liner, 4225A.164 with a tank cover locking device, 4225A.174 with both, and 4225A.105 with a right-hand lever. The bowl alone is part 3195B.101, which helps if only one piece is damaged. The Amazon offers linked here are the white models with the standard left-hand chrome lever.
Which Champion should you buy?
If you want no tank-to-bowl seam and a seat in the box, choose a Champion 4 one-piece: the 2034.314 for chair height or the 2004.314 if you prefer a lower seat. If the bathroom is tight or you want to save water, the Champion PRO round front is shorter front to back and uses 1.28 gallons instead of 1.6. Of the three, only the Champion PRO sheet lists WaterSense certification; check local requirements if your area limits flush volume.
Rough-in, supply and parts
All three are designed for a 12-inch minimum rough-in, measured from the finished wall to the center of the floor outlet. Check yours with our rough-in guide before ordering. The supply line is not included with any of them.
The Champion line uses a 4-inch flush valve, so buy flush-valve repair parts made for Champion toilets rather than generic 2- or 3-inch parts. Our American Standard toilet guide covers the Champion PRO elongated and other American Standard models.
