Floor Rot Removal

I had rotted wood under a toilet. Enough ceramic tile is out to reveal all the rot.
My question is--what is the best way to remove the rot section, being it is in the middle of the floor span?

Part of the rot comes within an inch of the wall. Thanks!

ps I'm getting a message that my attempt to upload a pic is too big, despite reducing the size 4 times? Any suggestions?

It's best to remove the sub floor to the next joist, when that isn't feasible you need to add blocking to support the patch piece.

I cut the flooring flush against the wall and to the center of the joists on either side of the damaged area.

Being that the floor is in an enclosed toilet area 3 ft across--the rot is close to both walls. What is the best tool to do the removing that close to the wall?

Actually at one wall side there's a baseboard heater to boot.

Just to rain on your parade... the rot likely does not stop at the walls. When you open things up you may find that the flooring is rotten underneath the walls.

I use a reciprocating saw (Sawzall), usually with a 9 or 12" long blade. With a longer blade you can flex the blade while cutting to make your cut right at the base of the wall. If using a shorter blade then get the top of the cut as close as possible to the wall and let the cut angle back. You can also use oscillating saws if you have one. They can easily cut flush though they cut slower than a Sawzall.

If possible cut out the central area with a skill saw set to the flooring thickness.
Then you can see what you are dealing with re: floor joists wiring etc.
Then use a oscillating saw/tool or reciprocating saw to cut further to the wall.
