So, I'm replacing the floor in a 2007 23rs after the vinyl flooring cracked over the winter. Using Plank LVT. the main area went in without issue. The bathroom is the issue. I removed the toilet. The new flooring is 1/4 thicker. Not sure the flange unscrews, at least, I can't get it too. Is there a thicker replacement seal? Anyone else have this issue? Any insight? Any pics if it does unscrew? Trying not to create more damage. Thanks in advance.
