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.

The description says heat resistant but I have a white circle on my gray composite sink after placing a pan in the sink. Will anything repair this? There were no warnings I saw when purchasing this product.
Hi Leah,
Thank you for reaching out, we can certainly look into that with you to figure out what caused the issue.
Please feel free to contact us directly by phone at 1-800-345-3358 or email at sinksupport@deltafaucet.com so we can review your issue together and assist.

What are the dimensions of the under sink mounting clamps… how far do they extend beyond the sink mounting lip?
Your install videos say cabinet base needs to be 3" larger than the sink, however, this 32" Everest sink says a 36" base is needed. Which is correct? Does this sink really require a 36" base cabinet? MODEL#: 75B933-33S-DG.
Hi Tropical Daze,
Thank you for your question. We are happy to assist you in this matter.
The general rule of thumb is you want to have at least 3 extra inches of interior cabinet space greater than the size of our sink. We require the extra space to ensure there's enough room for the mounting hardware required for installation.
For a 32" sink, a 35" cabinet should be enough.
Please contacting us directly at 1-800-345-DELTA (3358) or via email at sinksupport@deltafaucet.com for any additional questions or concerns.

best way to clean: daily and other maintenance
Hi Cabirdy,
That is a great question and I can answer that for you!
This model sink 75B933-33S can be cared for and cleaned using the methods and products listed below.
GENERAL CLEANING
To prevent water spots, clouding, and discoloration, rinse and wipe the inside of the sink with a microfiber cleaning cloth after every use. For a more thorough cleaning, use
water and a mild liquid soap detergent (ammonia-free). Apply the cleaner with a soft sponge or nylon brush and scrub in circular motions. Remember to thoroughly wash
away any extra soap left behind after cleaning.
HARD WATER SOLUTIONS & DEEP CLEANING
To prevent mineral deposits from forming on the sink in areas with hard water, rinse the inside of the sink and wipe it with a microfiber cleaning cloth after every
use. To deep-clean tough stains, products to consider include: Mr. Clean Magic Eraser, Supreme Surface Scum
& Mineral Deposit Remover. Make sure to follow the cleaning instructions provided by the product’s manufacturer.
THINGS TO AVOID
• DO NOT place pots, pans, or utensils straight from the
stove directly on the sink surface
• DO NOT use cleaners containing any abrasive powders, bleach, ammonia, alcohol, or chlorine. These products may damage the sink surface
• DO NOT use any abrasive pads, steel wool, or wire brushes when cleaning the sink. Using these will damage and/or wear down the sink surface
• DO NOT leave pots, utensils, or standing water in the sink, as this may cause rust stains on the surface of the sink
• Although Delta granite and quartz composite sinks are highly heat resistant, placing hot items right from the stove or oven directly into the sink may cause surface discoloration. Consider using a trivet or rolling mat for extremely hot items to avoid potential heat damage
• DO NOT place hot items from the stove or oven directly into the sink. Consider using a trivet or rolling mat for extremely hot items to avoid potential heat damage

Is the material safe to clean with vinegar? I know regular granite cannot be cleaned with vinegar.
Hi Mallory,
Thank you for reaching out, I can answer your inquiry.
