## Customer Reviews

### ⭐⭐⭐⭐⭐ Great sink...recommended!
*by J***R on August 5, 2018*

Love this sink. It looks professional quality, is easy to clean, and the granite makes it stand out from all the stainless steel options that are out there. I like the sink depth, can wash a bunch of dishes at a tim. One word of caution — the granite is not forgiving to plates and glasses like stainless steel can be so be a little more cautious when washing

### ⭐⭐⭐⭐⭐ Very good quality
*by R***H on May 12, 2023*
