Sheetrock meets bathtub

Tore bathroom down to studs. Put in new tub and now ready to put up water resistant sheetrock. There is a lip 3/4 of the way around the tub. I am ultimately going to put in tile on the walls. How is the sheetrock suppose to meet the tub lips. Is it suppose to be flush, hang over some or come over the lip all the way to the top of the tub itself or does it matter?

dkturnage,

When installing the backerboard or drywall, leave an 1/8" space along the area where the wall meets the top of a tub (nailing flange) or shower base (nailing flange). This area will be caulked later with silicon caulk. Caulk is flexible enough to allow movementósettling or expansion and contractionówithout cracking.

You do not want the backerboard or drywall going over the tub/shower base lip - this causes a "bow out" at the tub or shower base lip.

Hope this helps!

Not an expert, but to avoid confusion, you leave 1/8th between backerboard and tub, which is caulked Before you start to tile:

From:
http://www.doityourself.com/info/tileceramicprep.htm

"9. Position a 1/4" spacer along the rim of the tub to hold the backer board up slightly. Once all the backer board is up, but before you lay the tile, fill the gap with silicone caulk to form a water tight seal."

(see photo)

Then after tiling, you caulk all seams and accessories, soap dish, faucit escutions or plates, including the seam that meets the tub. The photos are from an old doityourself video, but the descriptions may have been updated for changes in technique? Not sure.

Most Common Mistakes

1. Not using the proper backing or underlayment as a base for the tile or not sealing the joints of the backing well.

6. Not applying silicone caulk around the lip of the tub or shower.

Vapor retarder over studs is recommended. Concrete underlayment board is preferred on shower walls.
