As always, you've gotta take into consideration the installation skills involved when pricing out countertops. With wood being a less popular choice, you'll be faced with specialized labor skills which drive up costs in relation to fabrication and installation professionals. Is it worth it? If your budget allows for it, yes! Just take a look at how unique and sophisticated this exotic wood countertop looks in a modern kitchen, especially with a super chunky profile. Most exotic hardwood countertop companies, on average, create custom wood counters to up to 18 feet in length, 3 feet in width, and 1 1/2" or 1 3/8" in thickness. Going larger is definitely an option; however, that usually means a lot more time, and again, extra cost.
