Shower Base Installation

[nelsonba]

I'm installing a shower in a new bathroom. The subfloor is tongue and groove wood and is not level. Could someone recommend a type of mortar to set and level the shower base in? Can it be applied directly over the wood subfloor?

It's fine over the wood.

Or you can use Fixall too.

Try WHITE thinset mortar.You can find it at H.D. in the tile section.No need for the expensive stuff .
