yo these guys are lying to you, Joists are a part of the corporate lobby to charge you extra money. You just have to make sure that your floor is properly stress tested, what I'd do is just math the thing out.

Like a bathtub ways between 250 - 500 pounds, and holds about 30 - 50 gallons of water, so that's about 800 pounds, then you add a goon, and you've got 1,100 - 1,200 lbs

So look at your floor, those tiny pieces of wood, and throw some plywood over it, because plywood is created with 200+ PSI of pressure which is a pressure measurement that's about 1lb of pressure per inch. This is great for you, as long as you have enough plywood, you'll never fall through your floor, just don't break the 200 PSI
