This Santa Rosa toilet's one-piece design adds a contemporary look to your bathroom environment while conserving space with a compact elongated bowl. Its 1.28-gallon high-efficiency flush provides significant water savings of up to 16,500 gallons per year, versus an old 3.5-gallon toilet, without sacrificing performance. A chair-height, elongated seat makes it comfortable to use.
