The Keurig K1500 is one of Keurig's commercial brewers with a UL Commercial listing and a massive 96 oz water reservoir capable of brewing 8-16 coffees ranging from 6-12 oz before needing to be refilled. And it's compatible with direct water line plumbing for even more low-maintenance operation.
Huge capacity is the K1500's calling card, making it great for workplaces or low-throughput commercial settings.
It also comes with most of the feature conveniences you'd want in a high-end Keurig coffee maker:
Despite the massive water reservoir, the K1500 is surprisingly compact with a countertop footprint of just 10.25"W x 12.1"D and it weighs just 10.2 lbs when empty.
