Question about crack in shower surround and buying used.

Ditto on all of the above responses.

If you decide to buy it I would seal it right away though. You don't want water to get behind it.

JB Water Weld is an amazing product. I used it to repair a crack around the shower drain. Which by the way mine cracked from storing too much stuff "in" the shower while traveling. Heavy stuff bouncing up and down. :(
