23 x 18 Inch Outdoor Stainless Steel Undermount Sink With Strainer-BRES23
A 23 x 18 inch undermount sink in 18 gauge 304 stainless steel, sized for outdoor kitchen islands.
This single bowl sink mounts under a stone or concrete countertop, so the counter runs right to the edge of the bowl and cleanup is a quick wipe into the sink. The bowl measures 21 1/8 by 15 3/4 inches inside and is 9 inches deep, big enough for washing produce, platters and grill tools.
The body is 18 gauge 304 stainless steel with a brushed finish. A stone guard coating and rubber sound pads on the underside quiet the sound of running water. The center drain comes with a stainless basket strainer.
The sink comes without a faucet, so you can choose the one that suits your island. Plan for a deck mounted faucet behind the bowl and water lines under the counter.

A Stainless Sink Made For Outdoor Kitchens
Our outdoor sinks are made from 18 gauge 304 stainless steel, the grade most often used outside because it holds up to sun, rain and changing temperatures. A deep single bowl gives you room to rinse produce, fill a pitcher or wash grill tools, and the brushed finish keeps water spots from standing out between cleanings.
With a sink in the island, the trips back to the house for water and cleanup go away.
What's Included
- 23 x 18 inch stainless steel undermount sink
- Basket strainer
Plan Your Sink With The Rest Of Your Island
Before you build, check the cutout size and base cabinet width in the specifications, and plan for water supply lines and a drain line under the counter. A sink works best next to your prep space, with the grill a few steps away.

You need a countertop cutout sized to the sink, a water supply under the counter and a drain line. The cutout and cabinet sizes are listed under Additional Information.
A drop in sink sets into the cutout and rests on its rim. An undermount sink mounts under a solid countertop such as granite or concrete. Many owners have a plumber connect the water and drain lines.
Yes. The stainless steel sink can stay in your island all year. In places that freeze, shut off the water supply and drain the lines and faucet before the first hard freeze so water does not freeze inside them.
Wipe the sink with mild soap and warm water and dry it after use. Skip steel wool and chlorine cleaners, which can scratch or stain the finish. A stainless steel cleaner wiped on in the direction of the grain keeps it looking new.
