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.

Receiving Your Shipment

  • Take clear photos of any box that shows damage.
  • On the delivery receipt, write down exactly how many boxes have visible damage. If it is electronic, have the driver show you where to notate the damage. Before handing it back, take a photo of the document showing your notation.

After the driver leaves, please immediately open and inspect the items themselves. If you find any damage, contact us with the following:

  • A photo of the item unboxed with the damage visible

Great sink for our outdoor kitchen

Exactly what we needed for our outdoor kitchen. 20 inches is a good size and the cover keeps debris out when we're not using it. Install was straightforward and the hot/cold faucet works perfectly.

Will I.★★★★☆February 11, 2025
Solid build, works well

Pretty impressed with how this sink is built. Feels solid, and ADA compliance was a big reason we bought it. The faucet is decent, but I might upgrade it later to something that feels a bit nicer.

Amir F.★★★★★March 15, 2021
Finally an ADA outdoor sink

Finally an outdoor sink that's ADA compliant and looks good. Fits right into my island. The cover is great for keeping it clean, and having hot and cold water outside makes cooking and cleanup so much easier.

Erin W.★★★★★July 29, 2019
Great quality

Great addition to our backyard entertaining area. 20 inches is just right for washing hands or rinsing grill tools. Really well designed, and it's ADA friendly.

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

The sink is solid and I like the ADA features. For the price though I expected the faucet to feel sturdier. Does the job, just not as premium as I was hoping for at this price.

Q
I have a standard counter cutout already. Will this sink fit without major changes?Asked by Sunstone Support Team
A
It's designed around common outdoor kitchen sizes. The cutout dimensions aren't listed here, though, and ADA compliant sinks usually have specific sizing. Check the spec sheet (on the product page, or contact us) against your countertop opening to make sure it fits without a lot of modification.

Q
What's the sink and cover made of? I'm worried about rust outside.Asked by Sunstone Support Team
A
The sink is high-grade stainless steel, which resists corrosion really well and holds up outdoors. The cover is typically made from a matching durable material, and it protects the sink when you're not using it, which helps it last.

Q
We have hard water. How do I keep this sink looking new?Asked by Sunstone Support Team
A
It's simple. For everyday cleaning, use mild dish soap and warm water with a soft cloth, then rinse and dry it well. That's especially important with hard water so you don't get spots. For tougher stains or to bring the shine back, use a stainless steel cleaner made for outdoor use and always wipe with the grain.

Q
I want to put this ADA sink in my new outdoor kitchen. How complicated is it with the hot and cold faucet?Asked by Sunstone Support Team
A
A capable DIYer or a pro can install it without much trouble. It comes with all the mounting hardware and pre-drilled holes for the hot and cold faucet, so the plumbing hookups are the main job. Have your hot and cold water lines and drain ready at the island for the easiest setup.
