Concrete – What thickness is most suitable for concrete countertops

concretecountertopskitchen-counterskitchens

If you had to choose between 2" and 2.5" thick concrete countertops, which would you opt for and why? Side note: I've heard that if you go bigger than 2" you need to start adding rebar, etc

I'm going to call this an aesthetic choice. But a bit of remesh/rebar wouldn't hurt, especially in a 60" long chunk or around a sink opening.

Personally, I'd find 2-1/2" overly heavy.
