I built the cabinet for the sink wider than necessary thinking I would need some adjustability in the placement of the sink. This ended up making a lot more work than it had to be. I started by following the instructions that came with the sink and built two supports for the sink. Then I heavily modified these supports to make them work with my cabinet. In the end, it all worked out. The sink sits flat and level, the countertop fits with the sink, and the plumbing works.
