Caulk vs Grout

I'm sure this has been discussed before - Where the tub meets the tile floor I've read normally caulk is preferred because you have two different materials meeting & the weight in the tub will cause the grout to crack over time. However if the outside wall of the "tub" is tiled (Basically tub is essentially "sunk" into a tile enclosure) would you still recommend caulk where the tile tub wall meets the tile floor since in this case they are the same tile material?
If I should go with caulk - Can I use sanded or unsanded caulk for that area - sanded caulk resembles regular grout better but does it work as well as the unsanded caulk in this area?

I would only caulk it if and when it cracks, and yes, if a sanded caulk matches, use that.

Anytime the tile changes direction like that caulk should be used.

Calk is used where there is movement as grout will crack.
It does not matter what the material is.

Un-sanded grout is used for gaps less that 1/8".
Sanded is used for wider gaps and it is stranger than un-sanded.

When tile meets tub or any other surface, they will expand and contract at different rates. Therefore, caulk, which is flexible is the correct choice to use at these junctions. Grout will only crack each and every time you try it.
