I have been working on remodeling my bathroom. As part of the renovations we have decided to replace our old tub with an acrylic claw foot tub. The tub is extremely light weight. I am assuming that it needs to be anchored some how so that there isn't constant strain on the plumbing for the drain. I talked to the plumber who helped me move the plumbing when I first started the remodel, but he did not have any answers for me. My floor is ceramic tile, and there is basement below the bathroom so I can get underneath the floor if needed. What is the best way to anchor this tub?
I believe you just set it on the floor and let the weight of the tub and connected drain pipes keep it from moving.
If you are really worried about it moving you could mount some sort of small block to the floor behind where each leg will sit. It would not be attached to the blocks but with for of them the tub would not be able to move. But that may not work well with your tile floor.
