Made in Denmark, uridan water-free urinals require no replaceable waste cartridges. Instead, they rely on a biodegradable, odor-blocking urilock fluid that is poured into the waste trap and floats on the surface of the urine to create a perfect seal. Urine flows through urilock and out of the waste pipe. This fluid remains effective for approximately 5,000 to 7,000 uses. Standard colors for ceramic units is white; for fiberglass units, it’s white, granite, and stone nero, beige and gray. Canadian distributor can be reached at 514-940-9944.
