I've got this annoying 1-inch gap on the side of my bathtub that tends to collect water. I'm looking for suggestions on how to keep that area dry and maybe make it look better. Any advice would be appreciated!

You might want to use backer rod to fill in the gap first, then caulk it well. Make sure the backer rod is slightly larger than the gap so it's snug. A good caulking technique is to cut the tube no larger than 1/4 to 3/8 inch and at an angle for smooth application. Apply two beads, smooth them out, and then do a final bead to top it off. Let it cure properly for a waterproof layer!
You could even turn that gap into a small planter for succulents! It's definitely an odd design choice they made here, and it seems like it wouldn't pass inspection. I think it was intended for symmetry, but it just looks off, especially with the misaligned drain.
If you're looking for a straightforward solution, consider adding another layer of tiles over that gap. It helps with both drainage and aesthetics!
One quick fix you could try is to install a PVC board that fits snugly in that gap. Just caulk it down afterward. It's a bit of a temporary solution, but if you do it neatly, it can actually blend in quite well.
I've been dealing with similar gaps around my tub! For now, I just cleaned the grout, then applied silicone along the edges and put a light layer on the surface. I also got a chamois cloth and a small squeegee to help manage the water. It’s not a perfect solution, but it helps a lot!

Haha, right? Those fins in front are bizarre! Plus, I can't believe how the drain doesn’t match up with the spout.
