   yes you tape it. Use fiberglass tape & be prepared to do a fair amount of feathering to make a smooth transition.

   Rob,
   Which joint compound do I use? I am using setting type compound for the 1st and 2nd layer, then a topping compound for the final. Thank you much for your help.

   T,

   You are doing it right. Just be sure & prime the exposed surfaces.

   *T,I like to bed all the cement board tape joints in whatever I am using for tile adhesive i.e. thinset or mastic. The transition between the drywall and cemant board is always tricky. If the drywall is also getting tile I use the same technique except at the corners and caps. If the drywall is not being tiled then I like to tile just over the taped joint. I've found if you do use drywall mud for the joint then you have to feather it out significantly or the tile won't lay flat. If you use the tile or bullnose to bridge the seam you won't have that problem.I don't know if using inflexible tile to bridge a seam even if it is fully bedded in adhesive is the 'correct' application, but I've had no trouble with it and it sure makes the finished tile job look better with less work to boot.

   I am putting a 36x36 inch fiberglass shower base in the corner of the bathroom. I built the side wall- 38inches. Now I am not sure how to make the transition from the cement board that I am putting behind the tiles in the shower to the water resistant drywall on the long side wall and above the tile in the shower stall. Do I tape this joint? Do I extend the tile over the joint? TIA!!
