Description

The Over/Under 34" x 12" Height Double Basin Sink (B-SK34) is a hand-built double sink for an indoor or outdoor kitchen. It installs either over or under the counter, so it can sit on top of a thick counter or mount beneath it, and all the hardware and instructions are included.

The sink measures 34" W x 20-1/2" D x 12" H and is made from 304 stainless steel in 16, 18 and 20 gauge. The basins are an extra-deep 10-1/4", built from 16 and 20 gauge steel that is much thicker than deep-drawn sinks, so they hold up to heavy use. The zero-radius design has 90-degree angles and sharp edges.

It comes with two covers with handles, made to match other Sunstone sinks and iceboxes.

Solid sink for outside

This double sink is a workhorse in my outdoor kitchen. The 34" x 12" size works for washing bigger BBQ tools and the two covers keep junk out when we're not using it. Install was straightforward and it feels very sturdy.

Kara Y.★★★☆☆March 8, 2018
Good, but a bit pricey

Decent double sink and the stainless seems high quality. I like that the covers are included, but for $748 I expected a little more, maybe a deeper basin. Gets the job done on my patio though.

Joy P.★★★☆☆April 17, 2014
Functional, nothing special

Put this in my new outdoor kitchen build. Good size at 34" x 12" and having two basins is useful. Drainage isn't as fast as I hoped though, and the covers feel a little thin for the price.

Joey M.★★★☆☆August 11, 2012
Does the job, could be better

It's okay. Dimensions work for an outdoor space and two basins is handy for splitting up tasks. I wish the steel felt heavier, it seems to scratch if you're not careful.

Chris T.★★★★★April 19, 2017
Just what our outdoor kitchen needed

Love this double sink. The 34" x 12" size is great for grilling prep and cleanup, and the two covers keep it clean between uses. Looks great and feels well built.

Q
Will this sink work with most outdoor kitchen cabinets as far as plumbing goes?Asked by Sunstone Support Team
A
Yes, it has standard plumbing connections, so it works with most outdoor kitchen cabinet setups. The drain openings are a standard 1.5 inches, so it hooks up easily to typical outdoor plumbing for hot and cold water and a P-trap. Just make sure your cabinet has room for the plumbing lines behind and below the basins.

Q
How do I keep this sink clean and looking good all year?Asked by Sunstone Support Team
A
For daily cleaning, use warm water, mild dish soap and a soft cloth or sponge. For tougher stains or to bring back the shine, a stainless steel cleaner and polish works great. Always wipe with the grain so it doesn't streak, and rinse well so no soap residue is left.

Q
What's this sink made of? How does it hold up to weather and heavy use?Asked by Sunstone Support Team
A
It's 304 stainless steel, which is great outdoors because it resists corrosion and holds up well. It handles rain, sun and temperature swings without rusting or pitting. With care it'll look and work great through years of heavy use.

Q
How hard is this double sink to install for a DIYer?Asked by Sunstone Support Team
A
With basic DIY skills it's usually straightforward. It can go in as a drop-in or undermount in a countertop cutout of about 32.5" x 10.5". Have a second person help lift and position it, and seal the edges well with outdoor grade silicone so water can't get in.
