I quoted the 1" thinking to go with overkill to avoid issues down the road. However once I had the tops in my possession I measured available thickness and determined 3/4" was the way to go. I'm armed with stone sealers for both the marble tops and the travertine sinks. We're definitely not going to be leaving soap bars on the marble...
The fabricator will come out to help with the install. It's going to be tight and difficult (I think) cause the tops have a wall on both sides. Wife wants to test fit the one now to get the "visual" but I'm holding off till we're ready to install. Once installed the fabricator will drill the appropriate holes for the drain and faucets.
This week it's time for the wife and I to start coming up with backspash ideas. I'll post again this weekend with the updated progress reports.
