Do you know how the Church discovered lightning rods to protect the steeples?
First, turn off the water going to the bathroom. Old tub if porcelain, ceramic, disconnect the drain and faucets, etc Lay down cardboard and plastic on the floor. Grab safety goggles and start smashing! Use a sledgehammer and you will get it out in no time. Then, when it is cleared, check the floor for rot decay etc you will need to repair that first. Check the floor and make sure it is level and the walls are plumb. If all is ok you can install, I am assuming here a new tub + surround. If it is all in one, make sure it will fit through your doors and into place. They are usually used in new construction and put in before doors and frames. You can buy a tub and then a surround for the top made of fiberglass inexpensively. If your walls are square it is relatively easy, otherwise you will have to build out or cut back into the walls to square it up. You set the tub in connect it to the drain. Keep the drain filled with a rag so you don't get any material in there while you measure, mark, and cut holes for the faucet and shower head to slip through. Some additional plumbing my be necessary. You will use silicone or other water resistant caulk to fasten to the tub and surround. The tub will have its own fastening issues. If you use a clear caulk for the joints and corners you won't see it as much or you can use white to match other caulk in the room. It takes a weekend to do this even if you don't have to sweat pipes or re plumb the walls. Good luck!
Having worked on a wind turbine farm I think I can answer this. They are struck often during a lightning storm. Since they are metal and come up from the ground, the electrical current will just run to the ground. They act just like a lightning rod.
