We are pulling out a Jacuzzi brand whirlpool and replacing it with a
Sanijet. According to Jacuzzi, they require floor strength of about 55
lbs
per sq feet. Surprisingly, Sanijet wants 100 lbs per sq feet.

The 55 psf figure "looks low."

Water is about 64# per cubic foot. If your pool is 1' deep, the water load
is 64 psf.
