Most garage sinks are stainless steel (commonly T-304), often offered in 16- or 18-gauge constructions; a smaller number of listings use aluminum.
Sizes range from compact drop-in/top-mount models (for example, a 15 x 17-inch top-mount) up to freestanding units listed at about 24", 28", 39" and 47". Basin depths shown in these listings are commonly about 9 inches or 10 inches.
Listings show multiple gauges, commonly 18-gauge and 16-gauge T-304 stainless steel. One listing specifically notes a 1.35 mm basin with a reinforced 2.0 mm rim.
Freestanding units include adjustable legs or levelers to stabilize the sink on uneven floors.
Common inclusions are a faucet and drain hardware (basket strainer/drain kit); many freestanding models also include legs or a bottom shelf. Some listings additionally list a bottom/grid rinse rack, wall-mount bracket, toolkit, and a user manual.
Warranty wording varies across listings; example durations found in the results include "1 Year Limited Warranty", "90 Day Limited Warranty", and "3 Month Limited Warranty."
