This was the easiest option I felt for the do it your selfer. The mats are good quality, wide enough, warm fast and work great. We put on 1/4" cement board over wood subfloor. We also added this product to the shower. I had to rework the mat a little to fit the drain for the Arc shower pan we used in the shower, but it worked with NO issues. I did purchase the shower mat and just moved the wired over to accommodate our drain location. I would highly recommend this product and I researched A LOT of them. I'm so happy we added this to our tiled bathroom, it will be wonderful in winter no regrets...

I don’t know, it looks good in the package
