you can try acrylic

Hi Prathi, It looks like the designer has not considered the depth of the dishwasher, and hence it's protruding out. Due to this technical error, the shutter placed over it will protrude out further creating an offset which will look ugly and also will spoil your edges under the counter. The only possible solution is to extend the platform (just the dishwasher area) and cover the dishwasher from top and then encapsulation of dishwasher with a shutter. See the sketch as follows in plan form.

Thanks for the reply..... The countertop used is corian ....how can the extension be made. Is there any other way we can cover it
