We had a shower pan made out of cultured granite for our bathroom remodel.
It was a dark color with flecks of red, white and grey (looks better than it
sounds). However, we noticed that it only looks like the color we asked for
when it's wet. As soon as it dries it turns really faded and almost
whitish. It looks horrible.

Apparently the contractor realized that they poured it using the wrong type
of wax. He says if he sands it down enough then it should look correct.
This shower pan isn't a flat surface only, though. It's got a front
(entrance) lip and three sides going up the wall about 4 inches. Is he
going to be able to sand the entire surface? We are afraid this thing is
going to turn out bad.

And this was the one and only time I ever tried having something custom made
for a remodel...
