I just completed a full bathroom remodel. When I installed the tub (American Standard whirpool acrylic) there were no installation instructions, so I did what I knew, I supported the tub with stringers. After a visit to the American standart site today to look for a heater, I stumbled across the installation sheet. It states it bold letters: THIS BATH MUST BE SUPPORTED ALONG ITS ENTIRE BOTTOM. What can happen if I don't correct this?? Can I pump cement under the tub now through the access panel?
Thank you!

Here's what I do. I fill the tub with water so it has weight. Then I reach under the tub with expanding foam, through the access pannel. Concrete is good, but as it dries it will shrink away. The foam is a compromise. I typically like to set them in mortar, as I'm setting the tub. But I have successfully used foam, as long as it is the no shrink type.
