This is a long single trough with two user stations. It may have one shared drain, two drains, or a hidden linear drain. The basin is continuous, but the faucet layout makes it function like a double vanity.
Where it works best: Luxury primary bathrooms, Jack-and-Jill bathrooms, hotels, offices, gyms, and commercial restrooms.
Customer dimensions needed: Overall vanity width, user station spacing, faucet center-to-center spacing, basin length, drain location or locations, backsplash height, drawer/cabinet layout, and whether the sink needs ADA-style clearance.
