Is Cedar a Good Choice Over MDF for a Bathroom Countertop?
Asked by CraftyPineapple73
I'm considering building a small bathroom countertop using MDF or a similar material that may be waterproof. My plan is to glue some 1/2" x 6" cedar planks on top and then cover the whole thing with epoxy. However, I'm worried about potential issues like shrinking or cracking. What do you think?

MDF isn't waterproof at all! I would recommend going with marine deck plywood instead. It’s a much better base for your cedar, especially in a bathroom.

Using commercial water-resistant MDF isn’t a great idea for a cedar countertop. Cedar will definitely expand and contract as moisture levels change, and MDF won't allow room for that. It could lead to a countertop that warps like a potato chip!
