The Cimmaron toilet from Kohler is a comfortable 17” high, the same as most chairs. The standard model is economical as well, using either 1.4 or 1.6 gallons per flush (GPF). An EcoSmart model is also available that requires only 1.28 GPF, 20% less than most toilets. Kohler’s exclusive Drylock system makes installation easy. The Cimarron toilet is available at The Home Depot stores.
