I'd like to point out a few things. Drywall is never the best choice but I have been in lots of 20 - 30 year old homes that have weathered just fine but on the other hand I have been in older homes were it did not weather good, I believe a lot has to do with installation and maintenance and just how close to water its getting.Shower curtains are famous for letting water escape out the sides so if there is regular drywall your going to have a problem at some point in time. checking the caulking is very very important, if it has a crack its going to let water in and thats a no no so if a person checks this and repairs it when it happens you have a better chance of it surviving.
I have seen lots of drywall fail with tile work on it, again its usually cracked caulking or the grout has either cracked or was never sealed.
So you see it really comes down to the installation and workmanship but if you notice there is a common denominator here " Drywall".
Green board has been used for years and the misconception is they say it's water proof ....Wrong, it is is moisture resistant but only for so long with repeated water getting on it .
Now having said this I have installed lots of green board around acrylic shower tubs without any problems but I take special care in the installation. I also point out to my customers the point I made above about shower curtains and they almost all put shower doors in. Buy the way do not use 100% silicone against a surface thats going to be painted instead us a mildew resistant acrylic caulking with silicone that way you can paint it. Paint does not stick to pure silicone. I use silicone when installing shower doors in these acrylic units.
