We do offer a few of the "triangle" shaped shower pans. We have the # LC325246 which is 27" long and 27" wide and 10-7/8" tall. We also have the # LC209795 which is 34" long and 34" wide and has a 5" rise. Both of these have a drain located in the center.
I have included diagrams of both shower pans below for your reference. view full answer...
