Grothouse Introduces New Laser Engraving Feature. The new option allows customers to have even the most intricate text or images etched into custom wood countertops. Clients can submit photography, digital drawings and custom text to be digitally engraved on any of the more than 60 wood species offered by Grothouse. The size and depth of the engraving can be altered to client specifications and applied to either the side profile or top of the piece. The engraving can be protected with the food grade oil finish, stained, or sealed with our waterproof Durata® wood countertop finish.
