Trying to get a wood frame mirror or a resin frame mirror for the bathroom and to make it a decorative wall mirrors. Would a wood frame mirror meant for the wall survive the humidity of the bathroom??. Also do resin frames look just as good? I mean are they good quality.

Some of the resin type frames (that look like wood) would be a good survivor in a bathroom environment. As for wood frames, if they are finished, with a good film finish, such as polyurethane, WB poly, or lacquer, would offer protection to the humid/moist conditions.

If you are fabricating one for your own use, and starting with a mirror, and it's a silvered back, there is a step you should take. Some providers of mirrors cut to size, use a plain, silvered back (dull grey) mirror. Others use a mirror with a coated back (more expensive).

The reason mirror turns black or the edges start turning black is that the silvering on the back oxidizes from the edges in. It's imperative that once cut, the edges get sealed. The easiest way to do this is to lay down newspaper on a flat surface, and lay the mirror face down with the paper extending past the edges. Using a spray can of clear acrylic (not lacquer) coat the edges and about 1" of the flat. This will help seal the edges. This should also be done to mirrors with a coated back.

That's a great little tip. I always was curious to why they do that.

There are also many sealcoatings for wood that protect against humidity and water damage, often used for boating docks.
