shower /tub unit wall board wet, to caulk or not?

I have an upstairs bath with a 2 piece shower/tub fiberglass unit. The tub appears to have a 1+ inch lip over which the wall unit sets. Should the gap between the wall and the tub be caulked? I have had problems with the wall next to the shower getting wet and having to be cut out and replaced. I have tried caulking the gap and no caulk, but can't tell if it has made a difference. Could it be anything else? The wall is at "the front" of the shower. The nozzle is directed away from the wall and the shower curtain is completely shut.

The area had been redone before I bought it and did not have any problems with the water until after a year.

Thanks for any advice/help.

Dave the not so handy man.

The joint between the wall and tub should be caulked. One problem many people run into is that they caulk with a dry tub. When filled with water/people, the tub actually "sinks" a bit - causing the caulking to separate from the tub/wall. Caulking will compress well, but doesn't stretch worth a darn.

Fill your tub with water before applying the caulking. Let it dry thoroughly before emptying the tub. This may help your problem.

Good luck.
