The Kohler Calidus is a two-piece, round-front toilet featuring Kohler's Revolution 360 swirl-flushing technology, which uses a 360-degree rinsing action to keep the bowl cleaner with every flush. The toilet sits at a comfortable chair height of 16½ inches, making it easier to sit down and stand up, and has an overall height of 31¼ inches. It is designed for a standard 12-inch rough-in and measures 29 inches from wall to front.

The Calidus flushes at 1.28 gallons per flush, meeting WaterSense efficiency standards and helping reduce household water usage compared to older 1.6 GPF models. The two-piece construction simplifies shipping and installation, and the classic round-front bowl suits smaller bathrooms where space is at a premium. The white vitreous china finish resists staining and coordinates with a wide range of bathroom decors. A toilet seat is included with the purchase.
