I've heard of Corian. What other products (brand names?) are there out
there that imitate marble or granite?

I would like to buy large sheets of marble-like material and don't know what
they are called and therefore where to find them. The home clubs (Home
Depot, Lowe's) have nothing other than el-cheepo tileboard and pre-made tub
surrounds. The pre-made stuff seems too plastic like and flimsy.

Product selections greatly appreciated.

Thanks,

Ivan Vegvary
