   In most cases it is necessary to support fully the bottom of the tub.  What you use under there is your choice-sand mix over concrete-you don't need stone aggregate.

   meadows,

   That depends on the tub manufactures instructions for installations.
   some require it , some advise it be done, some don't want it .

   You ought to be able to find the installation destructions online to let you look up what is recommended.

   Some tubs definitely benefit from some drystack; others will be better off with an expanding foam (the space to fill will commend either low 0r regular expansion foam).

   Using the foam can (just can) help the tub seem more temperate (less too-cold in winter; less too-warm in summer.  Your conditions will vary depending on the floor type, construction, etc.

   Personally, I've never liked any "feel" of springiness in a tub; but that may be from remodeling a few out of rentals . . .

   meadows-

   Placing a second floor tub I put a 3/4" cut to fit the bottom of the tub perimeter, placed a touch of plaster of paris on the ply and wedged it under the tub with wood stock. 

   Quick and easy.

   is your tub on a first floor slab?
