Tub, waste, and overflow unit
You have the right idea there. Unless water is getting spilled over onto the floor or assuming your tub is attached to the surrounding walls and it is spilling over to those walls, your waste and overflow gasket needs to be changed. I hope you have an access panel either on the back wall where the actual unit is or the side wall right next to it. Go to this site to see a picture.

Is it maybe the overflow valve since sometimes the water goes above it when taking a deep bath. If we caulk this, would it help? Any advice would be greatly appreciated.

Good morning Lisa,
I think you and Darrel were right on target when you zeroed in or the tub waste and overflow. I don't believe this can be tracked back to the valve or diverter. I think one of two things are happening. Either you're overfilling the tub and water's leaking past the sponge rubber gasket, (have you tried tightening the two screws on the face plate?) or you're splashing water over the sides and it's running down behind the tile. The simplest solution would be to just not over fill the tub. It sounds like you would be the perfect family to pitch a hot tub spa to. Cheers, Tom
