Wow ladies! Thank you so much for the responses~!
I do not typically have a moisture problem down there, but then again, one never knows. I do run a dehumidifier, though, just to keep it smelling nice and not stale or musty.
I can see where the no-carpet decision would be good just for the clean-up factor, but can appreciate the carpet for the warmth and quietness.
I did go and look at the acid etched and they are indeed beautiful. I looked online and I can probably do my entire room for less than a few hundred dollars. Amazing idea, thanks!
