Not knowing if the walls are either "water-proof" (doubt it) or even "moisture resistant", I've been extremely careful when showering, making sure that the curtain completely surrounds the tub & that the ends near the shower head cradled above stay overlapped. It is tedious in such a confined space, but we haven't had problems with wet walls, per se. However, I do check and towel off any stray drops that may have found their way outside the curtain or tub afterwards. I like Bill's idea of using a "chip clip" to keep the curtain closed while using the shower!
