I want to know is it Ok to put 3/4in tongue&groove in a bathroom. I don't find that there is a lot of moisture and there is a window that we use only in the summer. If not any suggustion. (no tile please)
Answer:
You sound too much like your mind is made up so I can't really suggest anything but the T&G and a suggestion that you be prepared to tear it all out in a year or two and go to something as simple as sheet vinyl flooring (floor and/or walls). If you don't have excessive moisture in there, you couldn't be taking showers and only cold baths on an occasional (weekly or monthly)basis.
