    Exclamation Securing Bathtub to wall

    Hello,

    I'm going to be installing an American Standard bathtub. I have placed a 2x4 as a stringer on the wall the length of the tub. Here is my question:

    How do i secure the tub to the wall?

    Few possiblities people are telling me.

    1. Leave it
    2. Drill a hole through the flange and countersink drywall screws to the stud
    3. Screw in a secrew just above the flange in the stud to prevent it from going up.

    Any suggestion on the best way to do this or the correct way to do this would be appreciated.

    Thanks!!

    1) Cast Iron- level it and it's done.


    2) Steel- I use screws with fender washers and screw into each stud just above the flange, so half the washer actually secures the flange/tub.

    3) Fiberglass- I screw right thru the flange into the studs.

    I have a steel tub. Maybe i'm thinking too much about this... but are there special flange washers?? Or are you just talking about a regular drywall screw with a small washer on the head. or somethign like that.

    Also if you do this...where do you stop the cement backerboard?

    At the top of the flange or do you actually go over the screw and washer and end up 1/4 above the base of the tub.?

    thanks again

    I use 1 1/4" drywalls with I think they are 3/4" fender washers. I screw them until they are pretty flush and the cement board goes right over them.

    So you extend the cement board down over the flange?

    thanks for your help

    Yes, I used to rest it right on the tub and caulk that seam before tile was installed. Some like too keep it up off the tub a little bit.
