"Our bathtub is an old and heavy-duty, but when we drew a bath, especially in the winter months, the water would be too cold by the time it'd filled up enough to get into the water. One day while I was in the crawl space under the house, I looked up and noticed the floor was missing under the tub, and I could see the entire bottom! I bought a small spray-foam kit and applied it all over, directly on the bottom of the tub and we could tell a difference immediately! We drew a tubful of hot water only, and placed a thermometer in the water. As it filled, the water was about 103 degrees at first reading; we let it sit for over two hours checking the temp every 20 minutes or so and the water never dropped below 95. Before we applied the foam, the temperature would've dropped below 85 before the hot water had run out.

Because of our one application, the main benefit we love is the fact that when we take a shower, we can stand directly on the floor of the tub without freezing the bottom of our feet in the early morning! We love the way the tub sounds more solid too. We really want to use the foam under more of our floor in our crawl space because the house (built in '46) has no tar paper between the sub-floor and the hardwood flooring. The wintertime is very drafty around our feet!"
