I'm redoing my guest bathroom. I plan to put in a larger vanity and sink. The tub/ shower is the problem. This is a fiberglass mobile home tub with a surround. I can't spend a lot of money but would love to get rid of the tub/surround. To make matters worse, it has a glass track sliding door. Can I remove the ugly door and go from there or do I remove the tub and install a new tub, which would mean tile to make it all come together. This bathroom is maybe 5 by 6.
