I realize a lot has to do with saving space as much as possible, but why are so many bathrooms designed with a tub? Personally, I find them to be almost useless and find myself using the bathhouse simply to avoid having to negotiate the cramped tub, and I am not a big guy. I also worry when stepping in and out that I, or someone else, might fall or trip. Whatever my next unit is, it will not have a tub!
