Black grout would be better.

And yeah, it's as bad as you think. If you aren't looking to sell in the near future you might get used to it and just let it be....

Another vote for black grout.

That looks like it was costly and would be so disappointing. I think he did a poor job of layout on the rest of the tile as well, especially in the niches. You might be able to color the grout you have so you don't risk harming the waterproofing on the floor (and someone is going to come along any minute and ask how he built the guts of the shower and waterproofed it). It that's as bad as the tiling, you may have no choice about a redo. Look for grout colorant for the type of grout you have.

Aloha to the 3 awesome people who responded to me.

Just wanted to update you that I followed your suggestion and half the first coat down of black on my grout. Second goes on tomorrow and you were correct...it looks so much better. 

I also wanted to show that the wall tiles look odd in the cubby from the angle I took the pic but they are actually symmetrical.
