Regrouting Shower- what should we use to fill the spaces?

The grout on a couple of tiles on our shower floor has been missing for a while. We had tried to refill it last year but the grout came up afterwards probably due to moisture that was underneath. We are going to regrout it again. We sucked out as much moisture as we can with a wet/dry vac and are now letting it dry out for a week. Is there anything we should use to fill the space other than regular grout?

    Sounds like you did a good job at cleaning. All you really need to do is apply the replacement grout (and caulk if needed). You should be good!
