Hello.

Is it absolutely necessary to lay self-leveling concrete on the entire bathroom floor, including under where the new bathtub is going to be placed, or can I install the new bathtub first and just lay the self-leveling concrete everywhere else?

Yes, the new tub would then be slightly recessed below the level of the new concrete I lay down.

What is the tub made from?

Fiberglass, steel, other.

A fiberglass one needs all the support that you can build into it.

Those dumb Styrofoam blocks stuck on it for support will decay in a few years and there will be no support left, and with even a light (200 lb) person in it cracks will develop and it will be junk, and need replacement.

As I asked what material is it made of?

Actually I haven't purchased the tub yet, but either enameled steel or cast iron. Cast iron tubs are pretty pricy though.

I should mention the bathroom floor is a solid concrete slab about a foot thick.

I've seen videos online of professionals self-leveling the floor without removing the tub. They just put weather stripping in front of the tub (and around everything else) and pour.

Is this okay to do with a steel tub on a concrete floor?

Thanks
