How to economically fix grout cracks in bathroom?




I discovered some grout cracks in between my tiles in the bathroom. It's next to the bathtub. I don't want to take all the grout out and redo it, so I was wondering if there was an economical way to do it that is just as durable.

You can use tub caulk. Just run a bead along the crack and use you finger to smooth it out.
If you're losing the grout in edges like your tub, that should never have been grouted. Caulk is what you need for corner edges.
How true. Grout is to seal gaps between tiles. Bathroom caulk should have been used between tile and tub. Just as Kelli and Shore suggest.
To make nice clean lines use painters tape and then caulk.
This will also allow you to force the caulk deeper into the crack.
yes - use a caulk made especially for bathrooms.
Should I remove all the grout first before caulking?
