Just got back from our soak tonight. It was a whopping 25F tonight! I have considered turning the tub's temp down. We have more than a foot of snow on the ground now, for the first time in a long time. The first time since I put the under the tub mount cover lifter. I've done a lot of shoveling, but not behind the tub, so the cover won't go all the way back. 40's next week!
