Oasis Custom Concrete Designs

Oasis Custom Concrete Designs casts concrete to order: countertops, sinks, vanities, fireplace surrounds, even tables. On its Houzz profile the business describes itself as O.A.S.I.S. (Original Art Set In Stone), a family owned and operated small business based out of Massachusetts, specializing in custom concrete countertops, handmade sinks and fireplace surrounds. The same profile lists Concrete Countertop Institute certification (CCI 2014) and Concrete Design School certification (Dustycrete 2017).
