In the final planning stages of my bathroom renovation and I have run into a minor snag. Looking for others who may have been in this jam. Tub surrounds - looking around at what's available, I see that most surrounds are now a "direct to stud" installation. However, in reading reviews, many homeowners say that they are flimsy after application. As it turns out...in talking to a person at American Standard....with these applications...it is basically necessary to add studding (I was told every ten inches) to add rigidity to the backing of the surround. I imagine one would end up with eight inch spacing since you would more than likely center additional studs between those already in place. I can't imagine a home that is anything but practically new to have stud centers other than 16" on center. So, I would imagine that my bathroom will have 16" centers. I didn't anticipate this situation, but the selection of surrounds available in the "direct to stud" installation is fairly large and enviable next to the paltry selection of the much simply "glue up" surrounds that would go up against green board. I am perfectly capable of adding studs to accommodate the direct to stud needs, and since I am gutting the bathroom down to the studs...the walls will be open. Just looking for anyone who has gone through this sort of thing with their installations. Anyone?
