: Working on replacing a tile shower stall and would like to install an insert. Current floor pan and area is roughly 34" deep by 36" wide - is there anything out there? (I haven't been able to find anything other than 36" x 36", and it's actually 37 1/4" deep.)

Ed,
With a custom size like that, you will need to either do a mud set base, or have a marlbe pan made up. Terry
