I thought floor underlayment was MDF?
If you plan on having lots of foot traffic and there is a chance the underlayment could get wet I'd go with plywood. |

My house has OSB subfloor, for what it's worth.

The reason we have to replace the floor is because there is a small section (one board) coming up, and she had several dogs in there that left a very foul odor. I don't know of any other way to get rid of the dog smell other than to replace the floor. Thankfully the walls are cinderblock so we're going to bleach them and frame them in with drywall.

There is a 3/4 OSB product that is waterproof. It is intended for use on floors. I do not recall the brand, but I have sen it at Lowes or HD in the past, it isn't difficult to find, and not much if any more expensive than the swell-up-when-wet stuff.

I wouldn't use it if you gave it to me. Every few years the breathless cries of "But it's been improved--this stuff isn't crappy like the old stuff!" comes up. Same shit, different iteration. Still shitty.
That said, if you are renting, use it. If you own the building, or otherwise don't want to put up with the problems inherent in it, use plywood, preferably 3/4" tongue-and-groove fir. |

3/4" T&G OSB is pretty standard for floors around here. Generally, a decent company will glue it to the joists to prevent squeaking.
It's fine. Hell, i used it on for floating floor when I expanded my retail shop. Part of it I carpeted, and the rest I put sticky tile right on top of. 3 year later and someone else is leasing the building and using it now  I only see the better custom builders using real plywood for floors.

Who has two thumbs and had AdvanTech replace a $25k wood floor on a house they built?
This guy!!! Long story short, we installed 3,000 s.f. of AdvanTech for the first time after using 3/4" T&G plywood for 30 years at the request of our Supplier and AdvanTech Rep. It was dried in well under the advertised exposure time, but still showed swelling on all edges. The Flooring installer sanded it down before floor installation, and the joints telegraphed into the hardwood a few months after completion. AdvanTech paid to remove the floor, skim the AdvanTech with 1/2" plywood and trim all doors and install a new floor to the tune of close to $40k. Needless to say, we've gone back to using 3/4" T&G plywood. OSB = Old Shitty Board |

OSB is also called "chip board" as it is shredded wood chips. Some chips are quite large, and all are much larger than saw dust.

You'll want something smooth under your cheap vinyl peel and sticks. They telegraph everything underneath them and they don't adhere well to rough surfaces.
At my big-box store, 3/4" BCX is $3 more per sheet than OSB. You need 4 sheets. Your budget can't handle $12? |

Use plywood and save in the long run. My mother had a house built with OSB flooring and we got in a huge argument about upgrading to plywood. She refused to pony up and 3 years after the house was finished the floors were creaking and nails were pulling up and into the underlay of the carpet. Cheap crap. |
