Bathroom walls deforming

Originally posted by GlueGuy Originally posted by Dirt Road Warrior Good news. If you get away from the insane heat the waviness goes away. So the issue is expansion of the panels in the heat?

yes, the heat seems to cause the walls to change shape but when it cools off they become flat again.

I have never visited Michigan. When is a great time of year to visit?

Just finished Cherry Festival week in Traverse City, ended with a finale of the Thunderbirds flying team.  Summers are always a hit, lots of water and beaches.  Where we reside (25 miles north of Traverse City) the very end of September thru mid October you find the forests ablaze with spectacular color.  Reds, yellows, oranges, and violets will make your eyes dance with amazement.  If you like picking sweet cherries there are many orchards you can go to and pick to your hearts, and appetites content right now! 

I confirmed that I have the same issue.  Checked the shower late afternoon yesterday with 95 degree heat.  Wavy walls plus the piece directly to the left had an edge bowing out that I could see under.  I checked it this morning with 70 degrees and the walls were almost flat again.  I could still feel a little waviness.  What concerns me is the long term impacts to where the one caulked corner is and to what is under the paneling attempting to hold it in place.  Will the caulk separate/crack due to uneven expansion of the 2 panels?  Will the adhesive give out under the panels?  I don't guess anyone has contacted FR yet.  Seems like the ultimate solution would be to replace the whole shower with something that doesn't expand.  If you start "nailing" it down in the middle, something has to give and will move the expansion to another location.

Seems like this post ought to be moved the warranty section of the forum.....,

Prior to FR changing to this new shower wall, they offered a sink delete kit which essentially patched the hole after you remove the sink. I called FR to ask for the kit and they said they didn't (couldn't?) offer a kit for the newer material. Others here have removed the sink and said it made a huge difference!
