You won't find this door as a regularly stocked item at your local home store.  Converting the bathtub and shower combo into just a shower was a little scary.  It became financially scary when I saw how much frameless shower doors cost.  I decided to see if Wayfair carried shower doors.  I was pleasantly surprised to see their large selection.  I feel like I purchased a special order shower door or the price of an economy shower door.   Before you purchase anything check Wayfair first.
