Deep Tube. The price was right with this tub.....BUT...there was a big problem. When I went to go clean the tube the first time with a basic natural tub cleaner spray....as soon as I started spraying the tub...it started turning BLUE! I have not been able to get the blue tint out of it. This was a natural cleaner with no chemicals in it. So I was shocked this happened. But once it's been installed there isn't a lot you can do. If you use natural cleaners...you might want to stay away from this one!
