Walnut Wood Plank for Bathroom Ceiling

1053 Views 22 Replies 12 Participants Last post by  Rebelwork
I am towards the end of a bathroom remodel project and am planning on installing a walnut plant ceiling. I have some old rough-cut walnut about an inch thick that I am thinking of resawing down to 5/16th and putting an 1/8 in chamfer edge on the sides and not doing tongue and groove. Do I need to worry about board movement with moisture in the bathroom? I did install a large CFM exhaust fan knowing I was planning a wood ceiling to help cut down on the moisture in the bathroom.

Also, was looking for thoughts on the best way to finish the walnut boards. I have been looking into Rubio Monocoat but also want something that will be fairly low maintenance that I won't have to redo every couple of years. Should I just use linseed oil then use poly?

Thank you ahead of time for any input you might have.

IMHO, any wood cieling in a bathroom is just asking for problems. You will have movement issues and you will likely have problems keeping any finish looking good. You may even have problems with mold. In addition, I'm not sure why you would want a dark ceiling in a small room.

As DrRobert said. Also, be sure to apply finish on both sides. It won't eliminate potential problems, but it may slow them down.
