How much caulking do we need to buy to caulk the rim of a standard 30" x 60" bathtub?

    If you need more than one then your tile guy sucked. – Mazura Oct 14 '19 at 20:34

One standard caulk tube will do a tub plus another.




The caulk link above - my go to. The gun is just an example (that brand gun is actually crap and pushes out too much even when no pressure).

The way I caulk a tub is to run a first pass that goes as deep in as possible, hit it with a wet paper towel or sponge (push the caulk in), wait about a half hour, and then do the second coat and smooth the finish.

  • A squeeze type of tube or one that goes in a gun? – Ed Beal Oct 14 '19 at 17:37

    Squeeze? Gun of course. – DMoore Oct 14 '19 at 17:55
  • The tubes they have that you squeeze like tooth paste but larger, have not bought one of those but I see people pick them up all the time. – Ed Beal Oct 14 '19 at 18:14

    @EdBeal - Those are fine for touch up but for a new line I just can't see it. They don't have any uniformity of the pressure and the caulk would be everywhere. Also don't think one of the toothpaste tubes would do a tub. – DMoore Oct 14 '19 at 18:37

    @Mazura - if you wait it hardens a little and there is less movement under. Also if you wait you can clean up better from the first pass. I also try to grout the tub/tile line unless it is the supercheap plastic thin ones. Even if the grout cracks you can easily apply more. Applying a little grout every 2-3 years is a 10 min job, a recaulk is probably a couple hours. I don't think doing both passes on the caulk is bad - I just find it easier to wait. – DMoore Oct 16 '19 at 2:52
