Description
The Bull 18-inch Premium dual-mount sink (model 12515) is a 304 stainless steel outdoor kitchen sink with a 7-13/16" deep basin, sold as a kit with a solid stainless steel hot and cold faucet, a stainless steel drain and strainer, braided hot and cold supply hoses and the hardware for either top-mount (drop-in) or under-mount installation. Bull designs it to stand up to the weather in an outdoor kitchen.
It measures 18-3/8" x 18-3/16" overall, needs a 17-1/2" x 17-5/16" cut-out for top mount or 16" x 14" for under mount, and weighs 19 lb. Bull supplies a cut-out template marking both cut lines and the 1-3/8" (35 mm) faucet hole. Need a different size? See the 15-inch dual-mount sink (12516) or browse all outdoor kitchen sinks.
Plan before ordering: bring hot and cold water lines with shut-off valves (not supplied) and a drain to the sink location, choose top mount or under mount before the countertop is cut, and plan to winterize the faucet if you live where it freezes. Bull highly recommends professional installation for under mount.

Installation planning
- Cut-out: top mount 17-1/2" x 17-5/16" with 1/8" corner radii; under mount 16" x 14" with 3/8" corner radii. Bull's template marks both cut lines; the under-mount cut line is flush with the inside of the sink. Check that no cabinet or plumbing is in the way before cutting.
- Top mount: drill four 6 mm starter holes and cut with the saw your countertop maker recommends; test-fit so the rim sits evenly, install the strainer and faucet first, seal the underside of the lip with silicone, then tighten the clips with wood blocks evenly until the sink is flush.
- Under mount (professional install highly recommended): drill a 20 mm (25/32") starter hole and a 35 mm (1-3/8") faucet hole, drill 3/8" x 9/16" deep blind holes for threaded plugs following the countertop supplier's method, seal the top of the lip with silicone and clamp the sink up with the clips.
- Plumbing: connect the braided hoses to supply valves (not supplied): red stripe to hot, blue stripe to cold. Connect the drain first, then open the supplies and check every joint and the drain for leaks. Do not overtighten.
- Freezing climates: the faucet must be winterized or the cartridge will crack. Turn off the water, remove the handle, cartridge cap, lock nut and cartridge, store them indoors, and drain or blow out the lines.
Care: Clean daily with dish detergent, water and a soft sponge; use a nylon pad with a mild, non-abrasive cleaner and dry with a soft cloth to avoid water spots. Remove lime deposits with warm vinegar. Do not use steel wool, metal pads or harsh abrasives, leave rubber mats, sponges or salty food in the basin, leave chlorine bleach in it for more than an hour, or let drain cleaner touch the surface.
