I agree with Oregano, but I will add that we had them come out and give an estimate about two years ago. They quoted us $4000 just for the shower in our master bathroom (which isn't very large) and they were backed up to the point where I think it was going to be 6 weeks before they could put it in. We ended up agreeing to do it (the salesman was very insistant that we sign the papers that night or we would lose a percentage off the total price) but backed out the next day (you have three days to back out of a contract in Maryland) because we just didn't feel comfortable spending that kind of money. The salesman was none to happy about us backing out and was not very nice about it. We ended up having a friend of my brother in law (he and his father own a small home improvement business) clean up the shower, redo the grout, and put in a new fixture and shower door for $955. Not quite as fancy as what Bathfitter would have provided, but it got the job done and was much more affordable.
So do your research ahead of time (there are plenty of customer reviews online) and know ahead of time how much you're willing to spend...don't let them pressure you into spending more.
