Is cement board waterproof for a tub surround?

Cement board may be water durable, but that does not by itself create a complete waterproof connection at seams, penetrations, and the tub flange. Use the waterproofing approach and compatible materials specified for the chosen system.

Should tile touch the bathtub deck?

The bottom tile edge should be planned with the joint required by the selected system rather than forced tightly against the tub. That joint is typically finished with an appropriate flexible sealant, while the waterproofing connection remains behind the tile.

Can grout waterproof the joint between tile and a bathtub?

No. Grout finishes tile joints but does not replace the waterproofing layer or the specified flexible sealant at the tub to tile change of material. The membrane and flange transition must be complete before tile and grout are installed.
