Anything better than plywood for floor?

Tackling a "soft spot" in the bathroom project...

I've got the bathroom floor all out. The sub floor was 1/2" plywood.

Is there a better/best type of sub floor material to use, other than simply replacing with the same plywood that was there before? As in, more moisture resistant and or stronger?

Figure as long as I'm doing it, and I only need one sheet of material, if there is something better to use, I may as well use it.

BTW... Pretty sure I've got the source of the leaks - from above and a plumbing leak hidden under the tub - fixed already.

Thank!

    Advantek is very strong and what I use on any single layer repair. Its available at lowes around here. It is however 3/4" thick. Good luck, will

    I like that idea, and had even thought about it, but wasn't sure if there was any such thing as pressure treat plywood.

    Definitely sounds like an upgrade over regular plywood.

    Thanks!

    Why not replace it with treated lumber plywood, then it will be resilient to any moisture, you know, the same type of treated lumber they use for making decks, only get the plywood, often used on the floor for small utility sheds.
