Picked up some Vinyl planks to redo the flooring in my bathroom.

Lay down some self leveling compound first if you're worried about it. Unless you seriously fucked up the subfloor I don't see it mattering but other than that a roll of underlayment first may be another option as well.

You could do a sheet of quarter inch ply, they make a kind specifically for underlayment that's smooth on both side. Or use acetone to take up the glue. Low points aren't an issue(assuming they're not large enough to affect multiple planks), high points are. Get a cheap wood chisel and a small hammer and knock them off. Plywood will only compensate for bumps so much, and it doesn't matter how good a sub floor looks as long as it's flat.

One option we have talked about was to put some 1/4 inch plywood down on top of the subfloor.

Since we took out carpet and carpet padding we lost a little bit of depth and that would raise it back up to be a less noticeable drop.

The issue is is that today (Saturday) is shot. Sunday we are going to my parents house after church to help them with some trim work so Sunday is shot.

Which leaves me with Monday morning to afternoon to get this done so i want my battle plan ready to crank this crap out.

There is one spot where they owners before me installed a laundry shout to drop clothes down to the washer and dryer but it was tucked away in a corner behind the toilet bowl and was very awkward to use so i decided to patch it but trying to patch someone elses work that cant cut straight is hard to do. there is one spot that i was debating on putting some drywall compound on to smooth it out. with where its at a foot never even gets set on it but its still a big drop for vinyl floor.

Hense why it is getting redone.

If your putting in lvp a 16th of an inch dip into going to matter it ain't sheet vinyl. Get rid of the bumps though. As for the laundry shoot cut a plug about the right size square. Then cut the hole to fit it much easier than making a custom plug. I can do 3 lvp bathrooms in a good work day so long as the prep isn't to crazy. You should be okay.

Do the planks you purchased have attached underlayment? Most new click-together flooring that I've dealt with does. If not, you can buy sheets of underlayment at home improvement stores. That may not be the most /diy/ answer, but this is a specific product made for your exact need.
