Mike, as mentioned, I would use spanish cedar for the flooring also. Anything else will make it that much harder to maintain consistant humidity. Also I would recommend a vapor barrier under the cedar (as mentioned). While the cedar absorbs most of the humidity (to a point), any moisture getting into materials beneath that could grow mold.....black mold......which is really bad stuff.
As to the door, line the inside of it with spanish cedar also. If you put in a window, I would NOT use silicone or any type of sealer on it. You want the window to "float" a bit in the frame to allow for wood materials to expand and contract with humidity and temp. If you just overlap the edges of the glass with spanish cedar, even if it's just a cosmetic strip of cedar, that will seal it sufficiently and still allow the window to float. An eighth inch gap around the glass is all you need for expansion. If you are really worried about humidity leakage you can just use some peel and stick weather stripping on the glass edge and then cover it with the cedar strips. No one will ever see it.
I just used the same peel and stick weather stripping on the inside edge of this cabinet. I have had it for quite a while now and always had trouble maintaining rh without constantly running out of water in the humidifier. I got the thinest my local hardware store carried (3/8th" wide x 1/4" thick x 17' long - Poly Foam Weatherseal). It said on the package that it fills in very narrow gaps and has maximum compression ability. I went ahead and did all the way around the doors. Closing it slowly, I just compressed the foam and locked the cabinet for a while. Now everything is fine, my humidifier runs about half or less of what it was and it's maintaining at around 60%.
You could also drop Charlie a line. He converted a closet years ago and lives in/around Cinncy. Find out any problems he ran into.
