This tub replaced an older high end name you would know tub. Due to a change in financial circumstance I could not afford to replace with that brand. I was nervous ordering this, but I am so happy I did, I could not be happier.  I was impressed with how quickly it installed and in 5 hours in frigid weather the water went from 52 degrees to 102 degrees. I am so thankful as I use my tub daily, as I have fibromyalgia.  It works with the pergola, stairs and cover opener from the one I was replacing. I could not be more thrilled!!
