Okay this question is for my son in Pensacola! He has a one piece fiberglass shower that he wants to take out and do an acrylic shower base and then tile the walls. The measurements are 46 1/2"(W)X 45 1/2"(L). I'm in Texas so that's all I know. He is having a hard time findinding a shower floor close to those dimensions. He doesn't want a tile floor in the shower. Any suggestions??
