Wainscoting in Bathroom Prone to Rotting?

[Tony Thompson]

Say I install wainscoting in a bathroom where it gets steamy during a hot shower. Is wainscoting prone to water damage over time?

I would also suggest not resting it on the floor when you install, and leave a small gap (that would then be filled with the silicone/caulk).

That way, if the caulk fails, it shouldn't wick up any water spilled on the floor.

Also, I personally wouldn't use MDF wainscoting, as if there is any penetration, it will swell and be quite noticable, where pine (or other real wood) wouldn't be as noticable if there was damage.
