Best way to strengthen this joist notch?

Hi all,

This is in my own house. I'm not panicking because it has been there years (don't know exactly how many).

It's in the middle of a roughly 3m span across the room (I know...) and it's probably 40% joist depth. Just one joist is notched like this. There is already a piece of ply screwed to the side like a 'sister' which is better than nothing but it only extends perhaps 150mm each side.

The bit that really concerns me is that two of the feet of a freestanding bath sit midway between this joist the the next (which isn't notched).

I'm considering fitting a steep strap. Possibly a right angled one along the bottom.

Any thoughts on the best approach? Sistering the whole length would be alot of work. There is currently floorboards & 8mm ply & vinyl & skirting on top of all this, this access easiest from below via kitchen ceiling. In hindsight it wouldn't have been better to resolve this when the photo was taken, alas.


Really grateful for any thoughts.


Maybe fit one of these from underneath? :

Thanks for responding.


Wouldn't the sister also needs a notch of the same depth to accommodate the pipe?
