Harness the power of the ultimate flushing machine with an Ultra Flusha® 1.6 gpf Pressure Assist Toilet. Boasting top of the line professional performance, its unique rim provides complete rinsing coverage with every flush. The tank uses a Sloan Flushmate pressure vessel which releases compressed air in a downward path and forces water into the bowl, pushing waste out through our extra-large 3" trapway. An exclusive six-point tank to bowl mounting system creates precise contact for superior stability and is designed to be tightened without tools.
