Currently breaking up the floor in the room that will become a bathroom, which was previously a bedroom. The house was built in 1920-21, and the floor joists measure 80 x 150 mm and are spaced with a center-to-center distance between 55-60 cm. I have read in numerous threads that you should have 45x220 as floor joists... But the thickness must also play a role here, right? There is no possibility to replace the old ones or insert 45 x 220 in between due to a heated basement below with already low ceiling height and numerous pipes and other things in the basement ceiling. And building upwards would be too much... At the outer edges, the joists rest on the wall, which is about 1 meter wide, and this is where the bathtub will be located. The span is about 3 meters since there is a wide basement wall underneath in that direction as well.
How to reinforce it more? Screw-glue plywood along the beams? Add more joists?
What do those of you who know about this suggest?

It certainly holds, but since it's a bathroom and you want as stiff a floor as possible, you can (at least for a good night's sleep) reinforce them. The thickness of the wood improves the strength of the beam, but doesn't have the same effect in terms of sway. A narrow tall stud gives less sway than a wide low one.
Screw-glue 45x145 on the sides, that's probably what I would have done.

Thank you. By using screw adhesives, I can also adjust the slight misalignment...
There is so much around bathrooms that soon it won't be possible to build bathrooms due to all the regulations...
