10 Best Hot Tubs 2025 in the United States

The FROG @Ease Mineral Cartridge + SmartChlor Cartridges is tailored for specific hot tub models, including those from Artesian, Marquis, Caldera, and Hot Springs. Its main strength lies in its dual-action sanitization approach. It combines a low chlorine level with FROG Sanitizing Minerals, which not only helps eliminate organic contaminants but also conditions the water for a softer feel. This product notably reduces chlorine usage by up to 75%, which can be a significant plus for those concerned about skin irritation and harsh chemical exposure.

Another appealing aspect is the maintenance convenience. The cartridge includes a mineral component that lasts up to 4 months, along with three SmartChlor cartridges that last 3-4 weeks. This means less frequent replacement and upkeep, which is ideal for users who prefer a low-maintenance approach.

Its use is limited to certain hot tub models, which could be a barrier for those with different brands or models. Additionally, while it does maintain a consistently low chlorine level, some users may still require additional chlorine or shock treatments depending on their hot tub usage and environmental factors. Energy efficiency is not explicitly mentioned in the product details, so potential buyers might want to inquire further on how this product fits into their overall energy consumption plans. Finally, other users might find that the upfront cost of the cartridges could add up over time, particularly for those with larger tubs or frequent usage.

The Coleman 4-6 Person Inflatable Outdoor Hot Tub is a solid option for those looking to enjoy a relaxing spa experience without the hefty price tag of traditional hot tubs. It comfortably fits up to six people, making it a great choice for small gatherings or family time. One of its standout features is the 114 jets, which provide a soothing massage experience, and the ability to heat water up to 104 degrees Fahrenheit enhances relaxation. The construction is noteworthy, with a three-layer material designed to resist punctures and stretching, ensuring durability over time.

The Freeze Shield automatic heating function is also a significant advantage, especially in cooler climates, as it prevents inner components from freezing during winter. Maintenance is manageable with a water filtration system that helps keep the water clean, and the kit includes a cover, pump, chemical floater, and filter cartridges, making it user-friendly right out of the box.

There are a few drawbacks to consider. Being an inflatable hot tub, it may not provide the same level of robustness and longevity as a hard-sided model. Additionally, the hot tub has shipping restrictions in certain states, which could limit your purchasing options. While it does well for relaxation, the heating time can be slower than expected, which may not suit everyone’s schedule. In terms of energy efficiency, while it's equipped with a thermal cover, users may still see an increase in energy costs, especially if used frequently. The assembly is straightforward, but the reliance on inflatable components can lead to concerns about long-term maintenance and potential leaks.

If you're looking for an accessible and enjoyable way to relax outdoors, the Coleman Inflatable Hot Tub is a suitable choice for families or small groups, offering a balance of comfort and features while considering the limitations associated with inflatable hot tubs.

This spa is not usable in temperatures below 39 degrees Fahrenheit, limiting its use in colder climates. Additionally, the product cannot be shipped to several states due to local regulations, which could be a drawback for some buyers.

It includes a Freeze Shield automatic heating function to protect the tub in colder conditions. The package comes with a durable liner, heater, ChemConnect dispenser, two filter cartridges, a repair patch, and a cover, making it a comprehensive kit.
