No. The only time epoxy grout is absolutely required is when using
certain natural stone tile. Some tile, notably Chinese green marble,
absorbs water from the thinset and/or grout, and will curl.
Use standard latex/polymer modified grout.
*It was more expensive and more work to install than other grouts when I
redid my master bath. However, epoxy grout never needs sealing and is very
durable. I would do it again. I know one tile guy that refuses to use it
because it is more work.
I did it on tiled kitchen counter tops and also, went up the wall to
the upper cabinets. It was really hard to do, but doable. I
divided each of the 2 parts into 4, by weight and did 1/4 at a time.
It did do well for wear. I don't think I removed enough material
when cleaning up the curing grout. Those higher spots, scuffed from
things like tin cans, etc. and would never come clean. This
happened in the 1st area that was done. I learned how much to
remove as I went on. I should have started in an inconspicuous
place. BTW, the new owners of the house said they were going to
remove the tile and put down plastic laminate .... yuck!
Over 15 years ago, I used pure white silicone with a tile that
matched. Incredibly easy, and still in very excellent condition,
no concerns about mold, mildew, or staining. With the tiles
snugged up against each other.
Grout is the weak link in a shower wall tile job. Not for me.
I gave details a few years ago.
