Hey everyone! I just discovered some wood showing near the drain of my tiled shower. I'm not entirely sure if it's due to KERDI or something else. I bought some silicone to fill the gap, but when I took a closer look, I found several spots like this. Do I need to rip out the entire tiled floor, or is regrouting an option? My house is six years old, and we've been diligent about using a squeegee after showers. A few times a year, I clean the tiles with a vinegar and water solution, following the tile guy's advice, but I'm not sure if my cleaning routine is contributing to the problem. Any insights would be super helpful! Thanks!

It could just be debris stuck in the grout or tiles, but if you've got around 20 spots, that seems less likely. You might want to investigate further to see what's really causing those issues!
It sounds like you might be dealing with air bubbles in the grout, especially if they were mixed too quickly. Fortunately, cement grout isn’t waterproof, so those holes aren't a total disaster. However, if there’s KERDI underneath, any punctures could compromise that waterproofing. You’ll probably need to regrout to make it look nice, but matching the color can be really tricky. You could also use silicone caulk, but again, it won't match perfectly. Just a heads up—using vinegar does gradually eat away at grout, but it takes a bit of time, so it might be exposing the weaker spots more quickly than others.
Ugh, I wish it was just debris too! But with multiple holes like that, it seems like it might be something more serious. Definitely look into regrouting or sealing those areas!
I heard from my builder that it could be the sand bed underneath. Does that sound plausible? If that’s the case, can I just silicone those spots?
