Sink base cabinet floor broken
I'm not sure if I'm supposed to put all questions in one post so I apologize if this is in the wrong place.
I've got my kitchen cupboards out for repainting and I see that the cabinet floor under the sink is warped and falling apart at the edge - enough so that I cannot attach one of the supports any more. The base is one large piece of particleboard (at least 9ft long by 2.5ft wide) and I'm wondering if I can repair just the necessary spot or do I have to replace the entire thing?
Thanks!

You can cut a piece of plywood, OSB or particle board to cover the bottom of the cabinet. That will give you fresh wood to re-attach the loose cabinet face. Or, you can just attach a small piece of wood for the cabinet face needs attaching.

Thanks Pilot Dane. I had considered attaching a piece of wood from the wall so that I could nail that cabinet face in and I'm happy to read that it is a viable option.
Mark, as much as I'd love to replace that whole bottom with plywood it would be a bit much for me to do. Limited resources here in terms of tools, transport and know how. I'm sure I'll get there some day though.

Particle board cannot withstand any moisture. Install sheet vinyl flooring in the bottom of the cabinet or be vigilant that the particle board never gets wet.

Caulking every crack and seam along with a coat or two of oil base enamel will give fairly good protection from water drips from above but you still don't want to let a leak go unattended.

Thanks for the additional information! There are no leaks under the sink and the damage is from the last owners. I'll make sure that the area is waterproofed just in case a leak happens again.

Yeah I would just attach small block of wood on top of the particle board (behind the vertical mullion). Then nail into that.

I went with the block of wood, XSleeper - actually I needed 2. The angle is slightly off centre in the pic but this is how it turned out. I had to mount them further back than I expected but they're sturdy and I'm happy with the results. I'll do paint touch ups today. Thanks again all.
