Sanded grout or silicone tub & tile caulking?

I'm looking to Dremel out the old grout between tiles in my shower pan. The gaps between tiles is only 1/8". Should I use premixed sanded grout or silicone tub & tile caulking from a tube? For starters I can't even find premixed grout in the almond color that I need. That's what led me to consider using caulking instead.

DO NOT use pre mixed grout.

DO NOT use caulk on the floor, just the corners

DO NOT use 100% silicon caulk, use the bathroom siliconized latex caulk

Premixed grouts are not rated for wet locations and therefore should never be used in a shower application. You want to use a grout from a powder and mix it up yourself in small batches. It is a lot of work to scrape out all the grout, but it can be done. I use a oscillating multi tool with a grout attachment. They use a strong utility knife to further evacuate the grout lines. Important to know what kind of pan you have so you don't breech the waterproof membrane. If on a cement mudbed, then you have little worry. If a kerdi membrane, you need to be cautious and not dig too deep or drag too deep with the utility knife.
