When remodeling a bathroom, it’s important to tackle plumbing updates while the space is accessible. Here’s how you can replace a toilet flange, adjust your rough-in, and handle a shower drain replacement.
Q: How can I replace my old toilet flange while remodeling?
A: Replacing the toilet flange is a good idea during your bathroom remodel. Here’s how you can do it.
-
Cutting and Installing the New Toilet Flange:
-
The first step is to cut the 3” ABS pipe. Once you’ve done that, install a coupling to connect the new section of pipe.
-
Next, install a new 3″ riser through the subfloor. Once you install the tile, you can adjust the riser to the correct height.
-
Finally, glue the new toilet flange into place, making sure it’s secure and level.
-
This method works well, but make sure the flange is properly centered and aligned with the toilet.
Q: Should I adjust the rough-in measurement for my toilet?
A: The rough-in measurement of 13 3/8″ is a bit unusual but may not require moving the toilet.
Since you’re planning to use a Toto Drake or Toto Aquia IV, check if the toilet model will fit comfortably with your current rough-in measurement. If the toilet fits, there’s no need to move the plumbing. However, if the new toilet is incompatible, adjusting the rough-in may be necessary. Be careful, as moving the toilet could involve a lot of extra work.
Q: What’s the best way to replace the shower drain?
A: For your Tile Redi shower pan, it’s important to handle the drain properly during your remodel.
Since your pan has a compression drain with no access from underneath, you’ll need to cut off the old drain and run a new 2” ABS pipe through the subfloor. When replacing the drain, you’ll need to install another coupling above the existing one, but it might be a good idea to cut the horizontal section and install a new trap and vertical riser for a better long-term solution.
By replacing the trap and riser, you’ll ensure the drainage is more secure and can handle future wear and tear.
