Bathroom Floor Tile: Prep Work that's Crucial for a Gorgeous Look

Who doesn't like a great looking bathroom floor? They're resilient and add flavor to one of the most important spaces in any house. We added porcelain tile to a bathroom that originally had blue carpet (that's right, BLUE carpet !!) Prep work is crucial to prevent cracked tile and extend the life of your transformation. Here's a summary of some notes (on prep work) I took from an installation we did a few weeks ago.
+Check the wood subfloor for water damage around the vanity, toilet and bathtub
+Replace wood subfloor panels that are warped and rotted
+Ensure the floor is level
+Secure any loose and squeaky wood subfloor panels using 2 inch deck screws
+Fix peaks less than 1/8 of an inch by sanding them down
+Fill in valleys using self leveling compound

If you have any tips you'd like to add please do so :)
The right prep for tile floors is simple and straight forward. Use a level, hammer, drill, deck screws, leveling compound to help with the process
And buy some knee pads, you'll be on the floor a lot :)

    This article has been very helpful. I am getting ready to start a bathroom remodel. For the new floor tile, I am going to make sure to check the subfloor that it isn't damage. If it is I will then replace that first before adding the new floor tile.
