How do I install a claw foot tub with a small doorway?

We are in the process of remodeling our bathroom and I am wondering if it is possible to put in an old style claw foot tub?? Are there any alternatives available that would fit better through a doorway?? Also we were looking into jet/spa tubs and a friend said something about a remodeling tub that comes in pieces and is better for installing in existing homes. I can’t seem to find these and am wondering if anyone knows anything about it. Thank you so much!! Hope someone can help with a first time diy!!
