We're having ours installed in a few weeks--we got white, 6" "tile" (extra $200over plain white), standard tub, ceiling, shower doors with frosted white glass, corner shelving and soap dish, and we had a coupon for free Moen fixtures (shower head/etc--claims to be a $400 value)--total came to $3800.
Not sure if it varies in cost by state but we are in NJ--and we had a very sweet and helpful salesman who answered all our questions and gave dh advice re: doing the rest of the bathroom "because it's so much cheaper if you do it yourself than have us do it for you"--I love honest salespeople!
Hope this helps!
