We just used Porcelain for all our countertops and island and I truly do NOT recommend it! It cost just as much as granite or marble, and while beautiful is SO delicate and was a nightmare to install. Apparently it is very hard to cut and we had to pay an additional deposit just to get an installer to accept the job. Once accepted, he cracked a slab twice. After installation, small fissures are now forming in random spots and while they aren't actual cracks yet, I'm nervous this slab won't last long. Just a heads up!
