An epoxy grout is always better in a wet area, but it is more of a challenge to install because it dries out so fast, still in the bucket! Aside from that, looking at your picture I don't see a big problem. I believe grout can be removed, one grout line at a time. It's time consuming and a big mess. What are your insurance company/contractors offering?

There's nothing wrong with that job. Looks fine.

That looks like a fine grout job to me, too.

Honestly I don't see the issue either. If you were that particular about the grout color it should have been chosen by yourself. Epoxy is used in a very small percentage of tile jobs so its certainly not the obvious option to have chosen. Again, if epoxy was what you wanted, you should have specified that also.

I will second everything Stait Tile said and also suggest that you try to color the grout before you try to remove it. If it helps, I think it looks fine from the photo.

I also don't see an issue with the grout, but that is a personal choice. Once you get beyond a standard white most of the options start to lean towards creams, yellows, grays or beiges in color. Personally, as a builder I would never select a grout for a customer. As a customer I would never allow someone else to select it for me. As far as type of grout, we don't use epoxy grout. We use the TEC Power Grout or Laticrete grout.

Given where you are, the best option that you have is to use a grout stain on the grout. It can be purchased at a tile store (not HD or Lowe's). It comes in small bottles and it would take several bottles to do a whole bathroom. You MUST remove any sealer that has been put on the grout before you attempt to stain it. It is painted on the grout lines and it is also a sealer so you don't have to reseal after you stain.

Good luck.

As many are saying, the installation looks good - just a color issue. As for using "Cement", almost all grouts are Portland Cement based, so that is normal. We use Epoxy in areas where we anticipate a lot of staining potential (commercial kitchen backsplash behind a range...), or when we need the grout to "stick" like to the sides of very thin glass tiles.

Also as many have said, sealers are not like a protective coating, they just slow down whatever is spilled on the tiles to minimize the staining, and have to be replaced every so often. One word of caution with removing the grout. If not done properly, you can damage the edges of the tiles while removing the grout. Need to decide if the color issue is enough to warrant the risk of doing more damage and/or replacing the entire floor. And confirm who is paying for all that with the people doing the work before starting. Staining the grout is much safer than replacing.

Also keep in mind you see it because you know it is there. Most visitors to your home will never see it. Look at grout in another part of your home or your friends. Grout color varies based on foot traffic and rarely stays one color. But if it bugs you terribly now, resolve it before the clock runs out with the insurance and contractor. Hope that helps? Robert

Everyone seems to claim there is no problem.. and that would be ok.. if the color of the grout was not supposed to match the tile. At the very bottom of the image the grout appears to be correct. I don't understand how all the "professionals" just let that pass by when clearly the result is as if you've picked a different grout shading from the pallet - yes, that's clearly another color, it's not seamless, YOU will notice it, which is the most important part, and whoever is going to do the job should be able to see and acknowledge that since aesthetics and grout color go together and you are paying for that specific grout color and result. It should be a controlled and default outcome for a "professional" - professionals should be called only those who can reproduce the same good satisfying high quality result - not everyone who gets paid to do it. Grout once dried should resume its original color and may actually go brighter as time goes by unless used for walking or in humid environment that keeps it wet etc - otherwise something went wrong - period. The job does look good - smooth textured - if you ignore the color. You are not crazy just demanding and you have every right to be as the price goes up but you can't make others as competent as they are paid to be so don't go crazy for them not being up to par. But if you are going to redo, find someone who understands and is not intimated by the above. My 2 cents.
