Large gap between tub and tile, 1/2", how to Caulk?

How would I go about filling this large gap around one of my unit's tub and then go about caulking the tub?

Gap is roughly 1/2". Do I use backer rod, grout, and then caulk? Not really sure here. I've never grouted before, and I'm pretty sure you can't use caulk to fill in a 1/2" gap. Thanks

That is a pretty big gap, hae you determined that the tub has hot settled do to structural issues with the floor underneath it?

Backer rod and caulking - masking tape off the wall and tub to pull a straight line.

I don't believe it's a settling issue, the gap around the entire tub is the same height. If I recall correctly, there use to be grout in that gap.

I'm not sure you can spread caulk across a half inch gap even with a back rod...I'd have to take multiple passes with the caulk. Never worked with a gap this large.

I'd suggest ceramic quarter round as the best solution or PVC quarter round molding as the easiest.

Interesting, then just caulk the top to the tile and the bottom to the tub? Never knew this came in pvc and ceramic. Very cool.

Do I need to adhere it with anything special? Or should the caulk on the top and bottom be enough?

Can you pull back on your picture and show me a full shot that includes the tub transition from horizontal to vertical. I'm not seeing how to appropriately dress out the tub to make pencil liner or quarter round look decent.

The vanity is in the way, but it gives you a good idea...

I'd still go with my original suggestion of backer and caulk.

I'd go with caulk also. That's what the backer rod is for, to fill large gaps.

I usually tool caulk with a finger, but you might want to use a caulk tool for this one.
