finish for bathroom wooden items

[breadstick]

I made a sign that will most likely get hung in a bathroom over the weekend.  I stained it with natural stain, but I don't know what type of finish to use.  I usually use a spray poly on my finished items, but I'm afraid shower humidity will affect it over time (as well as the glue holding the backer on).  Do I have to use marine varnish to be safe?

If it's made from hardwood I would use yacht varnish in fact what ever I would use yacht varnish. If it's good enough for a boat it's good enough for a bath room. Roly

Makes sense. It's whitewood, which surprisingly has a good grain, cuts very easily, and is very cheap. Might do these types of products with it from now on. It's supposed to be country/folk looking.

I used poly on my dining room table. It has held up through much abuse over the past 20 years. No water marks. Whatever finish you choose, be sure to get 100% coverage of front, back, inside cuts, etc.

Do you have other woodwork in your bathroom, such as trim, cabinetry, etc?  How have they held up?

 

My belief is that if you have excessive humidity and moisture problems in the bathroom, then those need addressed.  If there is enough moisture to damage a finished piece of wood, then there is enough to generate mold.  Something to think about.

Thanks everyone. It's not for me. It's to sell. Just trying to make a good product. I'm just worried about shower steam.

Spar Varnish or Tung Oil will work fine for that application.

I would use poly and not worry about it. Since there is usually plenty of drying time between humid ones I think you should be fine. 

 

As Bill Wilson said, if there is moisture to damage the wood, there is moisture to grow mold and that is a much bigger problem.

I like DW's  idea of spar varnish !

Just like rust if air can't get to it it stops growing,if water can't get to the wood no problems,my 2 cents worth.seal and finish

Ha, here's another case where I agree with MrsN. I have mahogany trim in my bathroom, it's been in there for over twenty-five years. It was coated with three coats of Varathane when installed, It looks as good today as it did when first installed. It's never been retreated, never seen the need to refinish.
