The top of the sink needs to be even with the cabinets so the counter will sit correctly. Measure the thickness of the sink and transfer that to the cabinet walls.
Farmhouse sinks are typically installed undermount and hence, are not compatible with laminate countertops. Look for an over-mount farmhouse sink that could be retrofitted with the cabinets and one that sits on top of the laminate countertop to eliminate the risk of water damage and warping.

This requires a full re-design of the cabinet and countertop where your farmhouse sink is installed.
The primary benefit of a grid for new farmhouse sinks is to protect the brand new finish. Fresh copper and even hardened fireclay scratch more easily than you might realize. The metal bottom of pots, the metal tines of forks, and even the scrape of ceramic plate edges might cause a small flaw in the finish.

Unlike regular “drop-in” sinks, which are lowered into a countertop cavity, farmhouse sinks are installed beneath the counter and rest on top of a base cabinet. They, therefore, require a special cabinet configuration, but it's entirely possible to convert an existing drop-in setup to accommodate a farmhouse sink.
By its nature, a farmhouse sink involves more than a traditional unit, and the price difference is justified. These larger, deeper, more statement fixtures are often made with more expensive materials, such as fireclay or copper.
