Sterling Dual-Flush Toilets

Description

The Rockton and Karsten are dual-flush, flapperless, gravity-fed toilets from Sterling (a Kohler brand), offering users the choice of a 1.6 or 0.8 gallon flush. The two-button flush actuator is integrated into the tank lid. According to third-party MaP testing, the Karsten Dual Force EL evacuated 400 grams and the Rockton evacuated 350 grams. Both models come with either an elongated bowl or a round front bowl, are made of vitreous china, and are on the Los Angeles Department of Water and Power's SPS-Certified Ultra-Low-Flush Toilet list.
