About the Manufacturer

For more than 40 years, Swanstone has been creating innovative and affordable solid surface products and materials for customers all over the world. It started in 1964, when they introduced the Swan Shell Shower, a doorless, shell-shaped shower that captured the spirit of its time.

The Shell Shower was the first in a long line of original kitchen and bath products from Swan, including the Circle Shower as well as the industry's first compression-molded bathtub wall system.

In 1987, they introduced Swanstone to the world, first with a line of vanity tops and bowls. Swanstone quickly became known for its superior impact strength, heat resistance, and ability to resist scratches and stains. Consumers now had an elegant and durable solid surface material that was also affordable.

Since then, the Swanstone line has expanded to include a wide variety of kitchen sinks, countertops, tub and shower walls, and more. In 1994 they introduced the Swanstone 1/4" sheet program, offering even more flexibility to Swanstone customers. In 1997 they introduced a complete line of Swanstone products for the restaurant industry, including tabletops, countertops, vanity tops, mop service sinks and windowsills.

At Swanstone, they're committed to a policy of continuous improvement, to providing their customers with the highest quality products and most responsive customer service in the kitchen & bath industry. And they stand behind this commitment with some of the best warranties in the business. © 2006 The Swan Corporation

I absolutely love it!

Jo from Seattle, WA– Verified Buyer

This sink is pretty amazing. I was all ready to purchase yet another double-basin stainless sink for my new kitchen reface and stumbled across this one. I read the reviews from several sites but decided to purchase from Wayfair, just in case this wasn't the sink for me, they have awesome customer service. I've only had it installed for about two weeks but it's gotten a bit of use having to move back into my kitchen and wash everything before putting it all away. It's way heavier than a stainless sink and feels so durable. It seems like it holds a ton. I'm able to wash my fridge trays and stove top grates with ease. And the water stays warm for hours, literally. I left my fridge trays in to soak, went to the store returned home two hours later, the water was still warm.

The sink looks great too. I have stainless and black appliances, maple cabinets with oil rubbed bronzed pulls and oil rubbed bronze faucet. It looks great with my ivory gold granite countertops. I just love it.

See it to beleive it....

Nike9090 from Seattle, WA

Brief history: We were looking for a sink which is not the boring standard sink. While searching the internet, found this sink which looks different and is not expensive. After few weeks for research and trying to locate the sink from a local distributors who gave up trying to find the sink, I finally took the courage to order [...]. The sink doesn't look fragile, but based on reviews, I was extra careful while handling the sink. The fabricators did mention that granite sinks can break during shipping or rough handling. The sink looks great and appears huge compared to our existing sink which is of the same dimensions. The sink was made in India. [...]. Fabrication/Installation: When the sink is glued to the countertop, there is a small gap which was filled with black paste (no idea what was used, but it's glossy) Due to the counter top thickness of 1.5" and the sink of .25", majority of airgaps and faucets won't work. We we lucky with the faucet, but had to customize the airgap. The sink was so deep that the disposer outlet was about 1" higher than the drain and if it was deeper, I might have to change the plumbing. Overall impression : It looks great and hides the dirty dishes as it's so deep. So far no stains from water. The Swanstone's website has CAD files of the sink and you should see them to be impressed. Will I order again from Wayfairs? Certainly and won't think twice. Will I order a Swanstone sink? Yes, without hesitation.

Swanstone ascend undermount sink

Cari from Kennewick, WA– Verified Buyer

I absolutely LOVE my new sink! We recently had granite countertops installed and I wanted something attractive with some style that would wear well and look sharp with the black granite. This fit the bill! We have hard water so I read up on how to care for it ahead of time and I'm not worried at all. My mother in law has had a granite composite sink for 9 years now and lives close by and she loves hers as well. I had planned to go with stainless steel to match my appliances and I'm so happy I chose this instead! I would recommend this sink to anyone looking for a durable, stylish sink that holds up well to everyday use.

Love the sink, but arrived much later than promised...

kara from goodyear, AZ– Verified Buyer

LOVE, LOVE, LOVE the sink! It is the perfect size and color. It arrived in one piece, however it was four days later than promised. I called instead of ordering online because I needed to know when it would arrive. The late arrival messed up our granite countertop installation time and we ended up having to wait even longer in order to get back on the schedule once it did come. That was a huge problem because my father was in town and I needed him to plumb the sink in after installation. We ended up working it out, but was much more of a hassle than it should have been.

Functional and stylish

AF from White Plains, MD– Verified Buyer

Purchased this for my Mom's new kitchen knowing that I liked the granite composite sinks (we have a double one). I like hers better than ours! It functions as a double sink, because of the raised tier, only it's better. Installing was simpler with less plumbing (only one drain hole) and it is sooo big since there is no divider in the middle so large pans and cookie sheets fit in it. Easy to clean (I use baking soda) and to shine it up I use WD40 a couple times a month - looks like new!

swanstone sink in blanco

Marleen from Menifee, CA– Verified Buyer

OMG!!! This sink is beautiful! Its hard to order somethings on line but this sink was exactly what i was looking for, i was not disappointed. I do a lot of canning and this sink is deep enough for my big pots. I also love the fact is one big sink. I love the raised side, i don't have to have a rack sitting on my sink, i set my pots and pans to dry on the higher side and the water drains into the drain and not on my counter. I REALLY LOVE THIS SINK.

granite sink

Grace from Charlotte, NC– Verified Buyer

I love my sink. It's nice and large and the raised section is perfect for holding vegetables as I wash them or plates to be rinsed. It is long and deep enough to hold muffin tins or cookie sheets as I wash them. The espresso color looks great with the bronze faucet we bought.

Future sink here today

Suzanne from Boca Raton, FL– Verified Buyer

One of the best sinks ...it's waterfall design is practical and is great for everything, washing vegetables and fruit or just for sitting dishes on.. The large area for pots is perfect. This is a way a sink should look going forward to the next millennium.

Finishing touch.

Nancy from Anderson, SC– Verified Buyer

Perfect sink. It is beautiful, functional and a perfect finish for my granite counter tops. It should have come with someone to do the dishes for me though. All that beauty and still have dishes piled up!!!

Karen from Queensbury, NY– Verified Buyer

This sink is really big! I haven't had a single bowl sink in over 20 years and feel I still don't! The ability to wash in the 10 side and dry on the 6 side is wonderful. I love the fact I can wash my LARGE pots AND baking pans without getting soaked!
