The Champion 4 One-Piece Elongated Toilet from American Standard is engineered for clog-free performance. This one-piece toilet features a 4-in. flush valve, the largest in the industry, to produce a fast, powerful flush that effectively clears the bowl. Designed for comfortable use and ease of accessibility, the chair-height bowl is 16 ½-in. high with an elongated shape that offers a more spacious interior bowl surface. The slow-close toilet seat eliminates the noise and annoyance of slamming.
