If it's not any bigger than the one in the picture, 1/4" of laminate is overkill. You can get away with 1/8" if you make the high stress areas (where fasteners and seacocks mount) thicker. That assumes the tub will be well supported once it's installed.
I would core the area where the seacocks are going. That will stiffen it up and provide backing for fasteners.
