Description

The ADASK20 is a 20" ADA compliant single sink with a cover and a hot and cold faucet, for outdoor kitchens, patios and bars where ADA compliance is required. The basin is about 4" deep and the sink is 5" high overall, so seated users and wheelchair users can reach it without strain.

The sink measures 20-1/2" W x 22-1/2" D x 5" H and drops into a 16-3/4" W x 19" D x 3-3/4" H cut-out, which works even over thick counters. Interior and exterior are food-safe 304 stainless steel that resists rust and corrosion, with a No. 4 light brushed horizontal finish. The zero-radius rectangle shape has angled top edges.

Included are a 2" cover that keeps weather, debris and pests out when the sink isn't in use, a chrome-plated hot and cold faucet, a matching soap dispenser, a large 3-3/4" kitchen-sized drain well that works with most garbage disposals, and all the installation hardware. Clean it with a mild detergent, skip harsh abrasives, and keep the cover on between uses. See our warranty page for coverage.

Great Sink for Outdoor Kitchen

This ADA compliant sink is exactly what we needed for our outdoor kitchen setup. The 20-inch size is perfect, and the cover is a nice touch to keep debris out when not in use. Installation was straightforward, and the hot/cold faucet works flawlessly.

Will I.★★★★☆February 11, 2025
Solid Build, Good Functionality

I'm pretty impressed with the build quality of this Sunstone sink. It feels robust and the ADA compliance was a key factor for us. The included faucet is decent, though I might upgrade it down the line for something a bit more premium feeling.

Amir F.★★★★★March 15, 2021
Perfect ADA Outdoor Sink Solution!

Finally, an outdoor sink that's actually ADA compliant and looks good! The ADASK20 fits seamlessly into my outdoor kitchen island. The cover is fantastic for keeping it clean, and the hot/cold faucet is a game-changer for outdoor cooking and cleanup.

Erin W.★★★★★July 29, 2019
Excellent Quality and Design

This sink is a fantastic addition to our backyard entertaining area. The 20-inch size is just right for washing hands or rinsing off grilling tools. Sunstone really nailed the design and functionality with this ADA-friendly model.

Hank W.★★★☆☆July 14, 2024
Decent, but a bit pricey

The sink itself is solid and the ADA features are appreciated. However, for the price, I expected a slightly more robust feel to the faucet. It does the job, but it's not quite the premium feel I was hoping for at this price point.
