I recently had my bathroom renovated, including floor and shower tiles. I love the tile color, but the grout I chose dried a few shades lighter than I expected. I did some research and found that grout can be stained a different color (I.e. grout refresh by Lowe’s). I was planning to add a sealer anyways, so it didn’t seem like a big deal. However, it’s not just grout in all areas. They added caulk in the corners of the shower (the caulk is the same color as the grout).
If I do choose to stain it, or even add a sealer, will that work in the areas that caulk was applied? Do I need to re-caulk, or will the sealer/stainer work on caulk too? Thanks for any advice!!
EDIT: Here's what I used:
Grout: Polyblend "polymer-fortified" non-sanded grout
Caulk: Polyblend "siliconized" non-sanded ceramic tile caulk

Your concern that the grout and caulk might take the stain differently is well-founded. Since the materials are so cheap relative to the effort of re-caulking (or, heaven forbid, re-grouting), you should pick up new grout, caulk and stain, and do a test on a piece of plywood. Make sure the grout and caulk have completely dried, or the results won't be comparable to doing it in your actual bathroom.
If this test works, and you get the same color on the grout and caulk, then you're still left with the uncertainty of how to apply the stain without it discoloring the adjacent tile and fixtures. So, think carefully about how you'd apply it, and do another small test in an inconspicuous part of your bathroom.
