I recently noticed some cracks in the grout in my shower, specifically at the top where the tiles meet the ceiling and at the bottom where the tiles meet the tub. I've never tackled a project like this before and want to do it right without messing anything up. I've heard a few options like using duct tape (which seems temporary and unattractive), silicone caulk (which isn't permanent, but might not look great), re-grouting with regular grout, or using epoxy grout. What's the best way to approach this situation?

You really shouldn’t use grout where the tile changes planes or materials, like at the tile-tub junction. Instead, you should be using caulk. Look for color-matched, sanded caulk that blends in with your grout; it’s specifically designed to handle these kinds of joints without crumbling. You can find it at a tile-specialty store, and if you need to match your grout, try getting a grout sample kit from the store. It can help you find the right color!
So should I just cover the entire joint with caulk then? And for the crack at the top, should I use caulk for the horizontal crack at the ceiling and grout for the vertical crack or just caulk everything?
