Awhile back I put in a shower surround and the place I bought it from went out of business.

The shower surround was a one piece with molded in shelves and grab bar. It was a bit thicker than the standard multi-piece units and came in an approx. 5’x5’x1′ box. The corners were flexible and ended in a gentle 90 degree curve instead of a sharp 90, thus the ends could be folded on the side to fit the box.

I’ve searched the net to no avail and was hoping someone might know a trade name for this style of enclosure to better define the search. Thanks
