Grout has disappeared between shower tiles!

Here's a photo of part of what I noticed in the shower today. There are a few other similar areas in the same corner, but this is the largest.

The grout seems to have crumbled away.

I know that grout isn't what actually prevents moisture from getting behind our shower, but I would still like this to be closed up again.

Would clear silicone caulk/sealer be an effective thing to use for right now, until we can get it grouted again? I ask because a.) we have some, b.) it's easy to use, and c.) it was even effective outdoors keeping rain from getting into a crack between our exterior wall and window frame.

Remove the loose grout and re grout the bad areas.

Hi, John! Yes, that is the best thing to do, but I can't bring in a professional tile person right now. It re-grouting easy to do?

It is very easy to do. Just follow the directions on the grout. The hardest part is matching grout color.

I still have the grout! I will do it!

Simple. Remove broken grout, pack in new grout, sponge with a moist sponge, buff when dry.

There is an inexpensive hand tool called a grout saw which is really useful for removing the old grout. Also, read the label on the grout to verify that it is rated for shower use. Some are not.
