partition wall over floorboard that needs replacing

[tnotty]

Having taken up laminate floor in the bathroom I want to replace the knackered floorboards with exposed reclaimed floor boards.

But... I've got a bit of an issue with a partition wall that sits over half a board.

Any advice on how to get around the fact that I cant remove this board but want to fit new boards throughout as the ones in place are beyond sanding and varnishing.

Is it just a case of cut it close to the wall and fit new board around it then skirting to cover join?

Diagram will make more sense:

Could you re do the floor map showing the joist positions?

Not taken up original boards yet but they run roughly as marked out here:

Cut the boards flush with the partion and fit a decent lump of wood to the side of the existing joist so the new reclaim boards are supported.

I'd question having open boards in a bathroom, how do you intend for bath / shower and pee pee water not to run between the gaps between boards causing damo, mould and rot issues?

Thanks chri5.

Has just occurred to me that i am actually taking the plaster board off the partition wall on the bathroom side to fit aquapanel so i may be able to unscrew the base timber from the board in question and then ease out the board and slide in new one.

The reclaimed boards I'm fitting will be squared up on the edges to should fit together with minimal gaps and also a coat or 2 of varnish will help to seal things up. Along with a couple of mats I dont forsee any damp/rot issues. (but time will tell no doubt )

Now considering an insulation layer while the boards are up. Kingspan??

Thanks again.
