Question: Did anyone put this over existing tile??
Document: For this great price, I am happy. I didn't have a lot of money to put into it, and it works great! No, it's not high quality, but I was realistic with the pricing where it is! I had the exact same style working in a different bathroom for almost 20 years and it does the job just fine!
What were they thinking?
This is a great product for the price, but you might want some help if you've never attempted something like this before. Follow the instructions carefully.
Okay so the product is thin which has been said many times. But that flaw could be used to advantage to conform to slight wall imperfections like corners that are not perfectly square or not so level walls, which as we all know is extremely common. Now for the bad part. The corners, being preformed, do no conform at the shelf locations. So now everywhere there is a shelf there is a gap between the wall and shelf.
Nice way to update a dated bathroom with an inexpensive, easy to mount tub surround in a neutral white color and texture.
Answer: no
