DO NOT BUY
This sink is said to be very easy to clean - it is impossible to clean and stains so easily. It constantly looks dirty because of how badly it’s stained. We bought it in 2021 and it was stained within a couple months. I wish you could add photos. BUYER BEWARE

Poor material feels and looks like a utility sink
We really love the "work" portion of this sink. Its great to be able to put pots or clean dishes on the rubber drying matt. Also love the cutting board. my biggest complaint is that the material of the sink feels like plastic and cheapy. It feels like a sink that should be in a basement. Not shiny and pretty for a nice newly renovated kitchen. It also absorbs stains very easily as well. Super disappointed in this purchase.

Stains Very Easily
I bought the white sink and unfortunately it stains and shows scuffs extremely easily. If I rinse out a pot that had pasta sauce in it, the sink stains pink. Regular soap and water won't take it out. It is such a pain to keep clean constantly. As I was researching sinks, I read that this material is supposed to look high end but honestly it looks like a plastic sink to me. I really wish I would have bought a porcelain sink. They look nicer and are much easier to clean.

Stains
We bought the white, and we have had it a year and a half and it looks brown. It started staining within 2 months of getting it. Im so frustrated by it that I want to buy a completely different sink. I have tried all the products, and it will never be white again.

We are replacing a drop-in sink which is 33" x 22". Our cabinet, from wall to wall under the sink, is 33 3/8" not 36". Is there a reason why your 33" sink requires a 36" cabinet? Will we not be able to replace with a new 33" sink?

How do you mount a garbage disposal on the everest 33?
Hi Robert,
That is an excellent question! and I can answer that for you.
You will want to install the disposal unit the same way you would into any other kitchen sink, the reason is that our sink has the standard size drain opening for the industry. The only exception to this would be if your disposal unit manufacturer makes a shallow flange, in that case you would have to request a deeper flange from said manufacturer.
If you have anymore questions please be sure to contact us directly by phone at 1-800-345-3358 or email at sinksupport@deltafaucet.com

Which kind of garbage disposal can be used with this sink?
Good morning- I am in the process of install a Delta Everest Black granite sink ith a garbage disposal. Should I use plumbers putty or the rubber gasket that came with the sink? Please let me know, I just want to make sure I use the correct seal. Thanks
Thanks for reaching out to us. Garbage disposals are 100% compatible with our sinks.

My installer told me there had to be a 1/2" to 1/4" reveal because of the accessories. Is that correct? I wanted a true flush undermount.
Hi,
Thank you for reaching out, I can answer your question!
This model sink does not require a positive reveal, however, some installers will opt out of doing a zero/flush reveal as it is the most difficult reveal cutout to achieve because it must match the sink rim perfectly.
As long as you do not cover the accessory ledge in the basin of the sink, you can have a perfectly functioning and beautiful sink installation.
Please feel free to contact us directly by phone at 1-800-345-3358 or email at sinksupport@deltafaucet.com with any additional questions.
