We live in central NC and I'm very familiar with hot, humid summers. Â We have a gazebo over our tub and in the warm months we put up a hose in the corner with a misting attachment. Â It really helps, especially if you are under the mist, but it also lowers the air temp all around the tub. Â We keep the water as cool as possible, and the shade from the gazebo helps some. Â I also keep 2-liter pop bottles filled with water and in the freezer and sometimes if we want to soak for a long time on a Friday/Sat evening, I toss the frozen bottles in the tub, about 5 of them. Â They lower the temp a bit and it cools you when you touch them. Â
