Do I need to regrout?

[kingskid]

I recently cleaned my 17 year old shower tiles and after I was done a I noticed some dark spots in the grout. Upon closer examination the dark spots were actually missing grout. These spots of missing grout a quite small in size, (about 1/16" diameter and range in length 1/16"- 3/16" in diameter) and there are not many of them. I'd estimate about 6-8 spots on all three walls of my bath/shower. The rest of the grout looks to be solid and in very good condition and there are no loose tiles. Does this sound like the it should be all completely re-grouted or can I have just the few spots of missing grout repaired? Thank you king

I would shoot a little caulking in those holes & that's it.

If it is in the walls, what he said, just keep an eye on things in case it gets worse. If it is in the floor, I would dig out old and regrout.

A dab of caulk will work as a quick fix if the grout is white. It may stand out since the new caulk will be whiter than the old grout.

You can use grout to fill holes, it'll give you a texture that matches better. If you use grout and the appearance looks its age, you can apply a grout colorant that will re-color, or even change the color and permanently seal the grout too.
