Are sinks a fixture?

Yes, sinks are fixtures, and they are among the clearest and most commonly cited examples. A sink qualifies as a fixture because it meets all the standard tests. Physically, a sink is permanently annexed to the property: the basin is mounted to the wall or set into a countertop or vanity, the drain is plumbed into the building's drainage system through a trap, the faucet is connected to the potable water supply lines, and the unit is sealed and bolted in place. Removing a sink requires tools, shutting off water, and disconnecting plumbing, which demonstrates the degree of attachment the law uses to distinguish fixtures from movable property. Functionally, the sink is adapted to the property's use as a permanent hygiene and utility station, and it was installed with the intention of remaining indefinitely. In plumbing terminology, sinks and lavatories are standard plumbing fixtures, listed in building and plumbing codes alongside toilets, bathtubs, and showers; codes assign sinks fixture-unit values for pipe sizing and require minimum sink fixtures in dwellings and commercial buildings. In real estate transactions, sinks transfer automatically to the buyer as part of the real property, whether they are kitchen sinks, bathroom basins, or utility sinks; a seller cannot remove a plumbed-in sink without contractual permission. Hardware and plumbing retailers stock sinks in the fixtures department. Therefore, in plumbing trade usage, building code language, real estate law, and everyday speech alike, sinks are unambiguously classified as fixtures.
