Finding hairline crack in tub
I think I have a hairline crack in our tub or shower surround. We are getting some wet wood under the tub where it supports the tub so I suspect I have a crack. Are there any good methods to find it. ...

If you remove the tub check the height carefully of all supports. Our tub has cracked and been replaced twice before we realized, with some members help here, the rear supports in the corner were 3/4" higher than than the front!
As a result, the tubs were not sitting flat on the pedestal. The rear side was not contacting the pedestal, and in essence, not supported. The constant flexing of the tub during use led to cracks. With both tubs the cracks appeared in the exact same place.
Tks. Will keep that in mind if I have to remove it. Were your cracks visible or did you have to perform a test to find them. I can't see any with my naked eye and an LED flashlight.
Mine were visible. About 6 inches long. Maybe because we are a family of three "heavy weights" and use the trailer full time, thus lots of showers.
You also can try running your fingernail, lightly, over the suspected area in both directions. Sometimes an invisible crack will "catch" the nail.
