Flushing at a rate of 1.6 gallons per flush and using a 4-inch piston action accelerator flush valve and a 2-3/8 inch trapway, the Titan toilet employs a powerful flush that can help keep your toilet from clogging. The Titan is a taller toilet, with a 16-1/2 inch rim height and an elongated bowl for added comfort and accessibility. The Titan also includes our revolutionary EverClean® surface that has antimicrobial properties to inhibit the growth of bacteria, mildew, and mold that cause odors and stains.
