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 simpl...

I wouldn't use any type of pressure treated wood product either. You have to use nails and screws that are compatible with it. And if it's sitting on top of steel or aluminum joists or frame parts, you're likely to get corrosion.
I would go with a better grade plywood. Marine might be good but I don't think necessary and there's other choices. Go to a plywood specialty store if you have one nearby. Why did you have a subfloor problem to start with?
If the joists are spaced too far apart, you could try either thicker plywood or add some bracing under it like angle iron or 2x lumber on the flat. Not sure how you plan to put it back in, but I would use construction adhesive for overlapping joints or wood bracing. If you have access from below, you could double-layer the plywood and use adhesive.
If you don't have access and if there's no obstructions below, you could cut a couple of pieces of plywood about 1-2" oversized all around then cut it in half. Then feed each piece in and glue it and screw from the top. Then add the final patch piece. If too many obstructions below, cut strips of plywood say 2-4" wide and put them under the floor to support the final patch piece and screw & glue.
