Reply to comment by Reelplayer in What shower caulk to fill a wide (1/2") gap by climbtigerfrog

A gap at the bottom won't stop water from working its way up since capillary action will "pull" the water up. And the gaps will get super gross unless it's constantly cleaned.

That's not true. The gap allows a pressure break so the water can just spill right back into the pan.

That's not how capillary action works. There is no "pressure" with capillary action.

Yes that's true. Technically it's surface tension. I figured it would just be simpler for others to understand if I said pressure break. And it doesn't change the point of having a gap.
