shower/tub combo

Do I need tar paper behind the 1/2" wonder board and is it necessary to use red guard?
Thanks, andy50

Welcome back, Steve.

From your title I'm guessing you plan to install ceramic tile to a tub/shower surround. If so, you need a moisture barrier behind your CBU wallboard and lapping over the drain side of the tub's tiling flange, or you need to use a direct bonded waterproofing membrane in the inside of the wallboard. But not both.

Thanks CX, the tub has no flange to lap the paper over so I guess the membrane is the only way.

If your tub has no tiling flange, your real options are to install an add-on flange or a different tub.

My opinion; worth price charged.

A different tub is not an option would sealing the wall board at the tub surface with silicone and use red guard on the surface of the wall board work?
The tub can be install like free standing tub or against the wall the directions say to use a tub flange I can't locate one a Lowes or Home Depot

Leveling subfloor

How can I level the sub floor of a bath room that is 6' wide and drops a 1/2" I planning on using wonder board.
Thank Andy50

There are lots of ways this can be accomplished, but one of the fastest is to use a mortar patching compound. An slc can be used, but you would probably need to make the whole room thicker to accomplish this, but takes less skill.

If you take the subfloor off, you can sister the joists so that they are level, and attach a new subfloor to it - this would be the one with the least buildup.

But, before you deal with any of this, have you checked your structure to determine if it is suitable for tile? If this is a slab, verses a wooden subfloor, you have a few other options.

Steve, it'll help is you'll keep all your project questions on one thread so folks can see what you're working on and what's been previously asked and answered. We can give it a more generic title any time you'd like to suggest one.

While I appreciate a minimalist approach to some things, it'll also help if you'll give us just a little more information with your questions. I'm gonna guess this is over a wood framed floor since you plan to use a CBU. And I'll assume further that you plan to install ceramic tile to the floor. Good so far?

If so, the tiles care not a whit about level, they care only about flat. If you also want the floor level, that's your choice, of course.

Tell us more about your floor structure. Likely help if you'll first run your joist information through our Deflectometer in the dark blue bar above to see first if the structure qualifies for a ceramic tile installation without any additional work. Then we'll need to know what you have for subflooring.
