I had to remove this bathtub subfloor because
of some faulty Plumbing but the first thing I did was add this port to my circular saw,
you'll see why in a second. Then I marked off the floor joist and just shy of both bottom
plates then I set the depth of the blade to be a bit more than three quarters of an inch and
I cut first with a circular saw and completed the cut with a reciprocating saw.
The cool
thing about that port is I connected the circular saw to my shop vac and that helped
reduce a lot of the dust. Then I pried off the subfloor panels and as you can see I have
some potential leaks. This full tutorial is available to our Platinum members in the New and
