I apologize ahead of time for the detail but it comes from a lack of experience and how to better express the problem.
Countertop guys come on Friday to install and have told me that is the time to tell them which of the 2 sinks I have at home I want. The templates that came with these 2 sinks are slightly different.
The first sink I bought has 2 X 8 inch deep basins which I had been told by the store (which is also who I contracted the cabinet installation thru and who did the measure) that should work. At the measure I was told that I should get 8 inch deep or less. I bought a compact version of a garbage disposal to hedge my bets.
Upon cabinet install it was determined that I should have been told 7 inches deep for the sink and that I may have to forgo the garbage disposal but to not return it until they came back to topmount after countertop install. The store also told me to bring home a 7 inch right basin and 9 inch left basin sink in case they would be able to cut a countertop hole that would accomodate both and leave the sink installers options.
Also, the piping is now slightly offset to the left hand side of the sink base.
Any input at all would be helpful. I can go without a garbage disposal much more easily than having plumbing problems.....
I am thinking that either sink might work without the garbage disposal but which one is more likely to work with a garbage disposal. The old sink was probably closer to 7 inches deep and the garbage disposal drained fine but the other side of the sink was very slow.
