Need Drywall Help on 60's Bathroom remodel

I am doing a remodel on a bathroom built in 1960. The walls were made of a layer of blue board with another layer of plaster. Due to the plaster smoothing out all the imperfections of the framing, the wall thickness varies from 3/4 inch to almost 1 inch.

I have gutted the bathroom down to the studs. Now I am looking at uneven studs that with a gap between the studs and the bathtub.

Somehow I need to get the cement-board to clear the lip of the tub. How do I do this when some of the studs hit the tub lip and some don't?

A few ideas I have thought of is:
1. Just hang 2 sheets of wallboard--the second will for sure clear the lip.
2. Somehow shim the studs to all line up right--I have no clue how to do this so that it will actually turn out right.
3. Nail new studs next to some of the old ones.

I am sure drywallers doing remodel jobs run into this all the time--any help would be greatly appreciated!

btw the room is 5'x8'

 

Welcome to the forums!

You would either shim out the studs to make them fit or install new 2xs along side of them. If 2 layers of drywall will work, consider using 1/2" plywood strips. Don't forget the cement board needs a vapor barrier behind it.

 

Thanks for the quick reply marksr. And thanks for the welcome =)

Looks like I have a lot of work cut out. I will try and get some pictures up after it's done.
