Shower Grout Swelling

The grout was going bad in our old shower/tub surround so I scraped it all out and re-grouted. I used un-sanded grout since it was 4" tile tightly spaced. I sealed it after about 36-48 hours and began using the shower again. After a couple days of showers the grout has absorbed the water, expanded and working it's way out of the joints. Any idea of what I did wrong or what is going on? I had replaced a tile once before and I think I used a adhesive & grout type product, could this be the culprit?

Thanks,
Neuner

I'm betting this tile is adhered to drywall? If it is, the shower is pretty doomed and needs a rebuild most likely.

Always use a portland base thinset for shower applications. If you used anything that came in a bucket, that's not a good thing.

Let us know what you got!

As stated below, something with the substrate. Push on the walls especially toward the bottom and see if there is movment. If the wall feels "spongy" then you have water absorbtion into the substrate which is more than likely just sheetrock or green board which are not for use in a wet area.
