Ian, I have 2 of those inexpensive fiberglass tubs. I use one in my laundry area and one in my shop. I bolted the legs of both tub to the floor, and the are really quite stable. If your concern is that these will move around, I think you will find anchoring them to the floor will solve that problem. Now, if you are after something to match a nice decor, these will not do that. They are functional period.
