Before your hot tub purchase, confirm the installation process for an easy and stress-free addition to your home. Hot tub costs can differ based on climate, model, and usage, but typical monthly electrical costs are in the $10 to $20 range. Plus, when you buy a hot tub that uses quality materials and the latest technology, you’ll save on maintenance, energy costs, and the expense of replacing costly salt water hot tub systems in the long run.
