Installing Hardibacker Over Drywall
Hi Dennis, CBU means 'cement backer unit' or something like that. Cement board, Backerboard all fall into that list. The CBU needs to go over the tub lip, use a paint on membrane over the CBU and then tile it. Either that or put a membrane like poly or felt paper over the sheetrock and then nail up the CBU without a membrane on the surface. With the sheetrock behind the CBU, it will be thicker than the rest of your walls.
You will need a plan for that. That's what CX was talking about.

Question: Can I use the tar paper I have left over from siding as the felt paper over the drywall. Integration By Parts Ti 84 Program. I'm going to the big city tomorrow( Redding, Ca) that's 50 miles away and can stop at HD and get a paint on variety membrane instead if that's better. I'd rather just use the tar paper since I have tons of it. Do you know what you are going to use to hang the backer board over the drywall? When I installed backer board around my tub, I shimmed the walls to account for the tub lip.
However, some of my studs were warpped and required extra shimming. As a result, the backer board was almost 1' away from the stud in some places. When I went to buy the backer board screws, even the long ones were not long enough. Now somewhere I had learned that you can't use just any screw in these backer boards. They have to be able to resist the corrosion of the cement and be listed as HD (heavy duty).
At first, I was not able to find a suitable screw that was long enough, and I wonder if you will not run into the same problem mounting backer board through a layer of drywall. However, the solution I finally did find was SPAX screws at Home Depot. They come in various lengths, and as best as I can tell they appear to be suitable to the application. I took Tile Joe's advice and went to a plumbing supply house today. I was sold on a Maax Tenderness acrylic tub with tile flange.

Also she referred me to a local glass shop and was I sold on an excellent looking shower door much better made and nicer than the Kohler I was looking at for only little more money.
After reading more here, I decided to do away with the drywall completely and use just the Hardiboard/membrane or maybe Kerdi but it's pricey. I went to a cool tile store also. So, should I order this Maax tub. Anybody have experience with them.
Contrary to common perceptions, tile and grout are not to be considered waterproof, and you should always put a vapor barrier behind them, and if you are using cbu, then it should go on the walls first. 1/2' on the walls, use the specified screws or hot dipped galvanized roofing nails (not electroplated), and use the special alkali resistant tape on the seams to tie the sheets together.
