Default Strengthening a floor

I have verified that the joists under the whirlpool tub are 2x10" 16 inches
apart. Too bad.... I was hoping to find double joists.

I should have provided some additional info with my post:

The house is 10 years old and built by Toll Brothers. Generally speaking
it is sloppily built but the floors were at least well spec'd out. For
example, under the kitchen there are all double joists even though the
span is not particularly long. According to the blueprint the double
joists are "to support the cabinets". Thru out the house the joists are
10 inches wide, 16 inches apart.

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. I am
looking for ideas on strengthening the floor. I have access from
underneath. I plan on adding an additional piece of sheet rock on top
and screwing it to the joists. Sistering the joists would probably be
difficult because a portion of the floor is cantilevered but I could put
in a bunch of blocking between joists underneath the whirlpool if that
would help. Any suggestions would be appreciated.
