If your sink and tub have overflow drains, why can’t your toilet? Penguin Toilets asked that same question and designed a secondary drain system that is built into the bowl of its Model 524 toilet to add protection against overflows. The new feature offers two areas of protection from overflows—one from the primary inlet holes and one from the holes under the rim within the toilet bowl. The WaterSense-listed unit uses 1.28 gallons of water per flush and has a raised bowl height of 16 1/8 in. for ease of use. No added work is required to install this toilet, and it can fit onto standard closet rings. Selected as the Most Innovative product in the 2010 K+BB Product Innovator Awards.
