poor epoxy grout in shower floor
I am attaching pictures of what I see as problems with the grout in our shower floor. The contractor sees no problem with these gaps in grout. I suspect that the dirt will get into these gaps and I will have a very hard time keeping this floor clean, not mentioning that these edges are simply sharp and unpleasant to walk on.
Any professional advise whether I am too picky or this is really not a good job?
thanks in advance.
