Hi BPS446,
Thanks for reaching out to us.
I'm sorry to hear about your experience and would be happy to assist.
As mentioned on our website and the specification sheet, our KWU110-30 offers the dimensions below:
Overall Dimensions: 30" x 19"
Bowl Dimensions: 28" x 16"
Sink Depth: 10
We've had many customers install this sink with no issues and the product dimensions have remained entirely the same. From what you described, it sounds like there may have been some confusion during the time of installation and we would be happy to review it with you directly.
I've taken the liberty of creating a case for you with our Customer Service Team: case: 292282. Please contact our customer service department at 1-800-775-0703 or by email at CustomerService@KrausUSA.com and refer to your case number so we can review your concerns directly.
Thank you for sharing your experience with us and giving us the opportunity to remedy the situation.
Best regards,
Mike
