I have a shower and the grout on the floor has hair line cracks in
it. The shower wall is fine, no problems. Upon looking closely at
the grout I found that there are holes through out it. The holes
don't seem too deep, the don't seem to be all the way through it more
like bubbles in the grout at the time of the application.

Can I simply just cut out the grout from the hair line cracks or
should I try to cut all of the grout from the shower base?
Can I spread grout across all of the tiles even ones that I didn't cut
the grout from? Will it bond?

Any advice would be greatly appreciated.

Since no one else has responded...

Since you are posting this Q you already know it needs to be taken care
of ASAP. No matter how much it involves it's nothing compared to water
getting through and doing structural damage.

Can I simply just cut out the grout from the hair line cracks or
should I try to cut all of the grout from the shower base?

Yes and yes. How much faith do you have where it's not cracked...yet?

Info that might help to an approach:
How big is the floor area?
What size are the tiles?
About how wide are the grout lines.

If this is a quality shower, it may have a waterproof membrane under the
tiles. This could be damaged if you dig the grout out too deep or too
vigorously and cause leaks. If it is a builders special, there could be
anything under the tiles, probably water saturated concrete over a vinyl
waterproof sheet.

I can't help but picture a shower with poor support and a "spongy"
floor. It will just crack again and again. Hopefully I'm wrong.

Thanks for the input. From your responces I am going to try to remove
all the grout with a dremel multimax tool and re grout it. I think it
will take some work but hopefully the grout won't crack again?
