Upgrade your bathroom with the Champion 4 Tall Height Elongated Toilet from American Standard. This high performance toilet has a 2-3/8 in. trapway and 4 in. flush valve (the largest available), so it almost never clogs. It also moves larger masses than most toilets available and has a bulk removal rating of 1000 g in a single flush, making it a leader in the industry. Each flush uses only 4.8L of water so you not only get superior performance but you save water and money. The PowerWash rim scrubs the bowl with every flush so cleaning is easier too.
