Step 5: Grab a piece of board from the home improvement store. I choose to go with particle board as the bottom layer that attaches to the subfloor. This should never see water because the top layer I will choose a more water-proof board. Measure many times and start cutting the board to fit around any vents, as well as cutting out water pipe slots.


Step 6: Fit, screw, and seal the piece in. I used acrylic caulking in any gaps. For the larger gaps next to the water pipes, I used water-resistant wood filler. I'm not sure if I should slap a sealer on this or not. What do you guys think?

More to come as I further progress!
