Here’s a photo of a Best Hot Tubs client who clearly has made using his Bullfrog Spa a priority — no matter the amount of snow. Note the deep path he has shoveled (right side of hot tub). He’s a man who truly wants access to his hot tub…polar vortex or not. After Snow Storms: After it snows, clear a path to your hot tub — not just so you can use your spa — but so you can maintain it during freezing or snowy weather; 3. Protect Spa Pipes: To keep pipes from freezing, once a week check that the hot tub is running and make sure the water temp is at least above 90 degrees. (Note: In extreme cold temperatures, it is cheaper to maintain the temperature than letting it cool down and reheating it again.) Spa Water Level: While checking its temperature and that it is running, also watch your spa’s water level. If the water gets too low, the pumps and heaters are affected by insufficient water, and this can contribute to freezing in spa’s plumbing lines;
