Il wondering if they’ve possibly misquoted in the first place? That is a huge jump, but if you can’t change anything about your design, it is what it is.

They are ripping you off. You don't get 6K for 6 inches more. Get your money back please.

You are buying 2 more slabs than they originally thought, just by the pure square footage given to them. The layout with the waterfalls, and miters, eats up slabs, in order to maintain good seams.

"among other things they claim were unexpected." You have outlined what you have but what information did you send them initially. How wide is the island?

I would give them a second chance and they are trying to make it right for you. If you find someone on your own you won't have that back up.

These people tried to rip you off. No second chances please.

I am a fabricator and I have done literally thousands of bids from drawings. Occasionally a dramatic increase happens due to thinks like access restrictions that substantially add to install cost or additional parts like a buffet top not included in the drawings The $6000 increase for relatively minor dimension differences is bullshirt, they are playing rope a dope. Get your deposit back and find an honest fabricator. Note: there is one instance where a dramatic increase can occur and that is when the selected color is not a stock color for the fabricator and the small change in dimensions necessitates the purchase of an additional slab by the fabricator. This would not be the fault of the fabricator.

Joseph - sorry I meant giving Ceasarstone a chance to choose another fabricator.

Thank you all for your input. This has been so stressful—truly the most stressful part of our home reno.
