Do I need to caulk this?

[Forester Fred]

My wife is concerned that the edge of the shower walls are not caulked where they meet the floor pan. (See photo) I pushed on the walls a bit in that area and it feels like the floor pan goes up past the bottom of the walls by a couple inches.

Does this need to be caulked or is the overlap (if there is one) of the wall over the floor pan sufficient?

Thanks

There should be a luo that goes up a couple or few inches behind the wall panels. If you caulk it, you'll always be re-caulking it. Also, if moisture does get behind it, it is supposed to be able to drain sheen and away rather than be trapped. Either way is fine, but I'd leave it unless you have reason to believe moisture is going uphill.

Captain, my shower pan was replaced in Goshen. The pan comes up about 1 1/2" behind the wall covering.
When the repair was finished, the tech caulked all the way around the interior of the shower including the glass panels and bottom door sill. (That all had double sided foam tape for a seal when it was removed. Yours may be sealed that way also.) The caulk was some form of grey silicone. It was interesting to watch him liberally apply the caulk and then clean up the excess with a lot of acetone and several clean rags. It looks outstanding BTW.
