Walnut Wood Plank for Bathroom Ceiling

1046 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.

It's an interesting idea, and some great looking walnut.

From a design perspective it isn't something I would do, will be dark, unless this is a bathroom in a man cave that isn't what you will want.

Beyond design and aesthetics it is not a good idea from a material perspective. It can be done, and it might be OK, but why waste that great wood, the time, and the effort.

Might post a pic of the bathroom so we could see what you are dealing with.

I appreciate everyone’s input and advice, which is what I was looking for in joining this forum. This gives me a lot to think about.
After reading through all the comments I am leaning towards using a pine tongue and groove “car siding” instead of the walnut and staining to match the woodwork of in the rest of the house. I can use the walnut for other projects.
I still want to do the wood ceiling as this was the original design back when we started the project. With a 100 year old house we want to capture that time era design with a modern flair.
Here is a picture of the bathroom with white subway and white hexagon tile floor. The top part of the walls will be white shiplap that I am planning to make after finishing the ceiling. There will be a wood ledge on top of the neil walls that will match the color of the ceiling.
I will definitely be sure to seal whichever wood I go with to help stretch out time before having to fix any of the wood ceiling issues that will eventually come around.
Again I appreciate everyone’s input.
Looks great!
