replace kitchen sink?

There is a difference in sink sizes between residencial and RVs. DW was unhappy with our RV sink white fiberglass and wanted a granite composit like she had in the S&B's. I was able to replace with what she desired because our countertop was oversized allowing installation though plumbing needed to be changed, old sink ws 7 in depth new was 9 in depth needed remodeling as sink was in slide and would not drain without replumbing.

Sorry didn't really answer the OP question completly just google RV kitchen sinks there are several suppliers of RV sinks, Stainless and fiberglass. Measure your sink, they are probally 17X32 should be a drop in if you stay with the same size.
