Softub Spas offer a unique alternative to traditional hard-shell hot tubs, focusing on portability, energy efficiency, and comfort. Unlike standard spas that require dedicated electrical wiring and heavy equipment for installation, these units are designed to be moved and installed by a single person. They use high-density foam and specialized heating technology to provide a relaxing experience without the high costs often associated with home spas.
Whether you are looking to soothe sore muscles or create a relaxing space in your backyard, understanding how these portable tubs work is essential. This guide will walk you through the different models available, how to set them up, and the best practices for keeping your water clean and safe for year-round use.
What Makes Softub Spas Unique?
The primary difference between a Softub and a traditional hot tub is the construction material. Instead of acrylic or fiberglass, the walls are made from Polybond, a high-density, open-cell foam that provides structural support and excellent insulation. This material is lightweight enough to allow the tub to be rolled into place through a standard doorway or gate.
Another defining feature is the HydroMate system. This unit combines the pump, motor, and heating system into one compact exterior component. Because the system is separate from the tub itself, it is easy to access for maintenance or storage during the off-season.
Finally, Softub Spas are known for their “plug and play” capability. They are designed to run on a standard 110V household outlet, which eliminates the need for expensive electrical upgrades or professional electricians during the setup process.
Energy Efficiency and the Heat Recovery System
One of the biggest concerns for hot tub owners is the ongoing cost of electricity. Softub addresses this through a patented heat recovery system that captures the heat naturally generated by the motor. This recycled heat is used to warm the water, significantly reducing the amount of energy required to maintain a consistent temperature.
The Polybond foam walls also play a major role in energy conservation. The dense foam acts as a powerful insulator, trapping heat inside the water even in colder climates. When the insulated lid is securely fastened, the tub loses very little heat to the surrounding air.
Because of these features, Softub Spas are often cited as some of the most eco-friendly options on the market. Most owners find that their monthly electricity bill increases by only a small amount compared to the significant costs of running a traditional 220V heater.
Comparing Softub Models
Softub currently offers three primary models designed to accommodate different space requirements and seating needs. Choosing the right one depends on your available space and how many people you plan to host at once.
- Softub Sportster 140: This is the smallest model, designed for one to two people. It is ideal for small patios, balconies, or individuals looking for a personal therapeutic soak.
- Softub Legend 220: The most popular choice for couples or small families, this model comfortably seats up to four people. It offers a balance between a compact footprint and enough room to move around.
- Softub Resort 300: The largest model in the lineup, the Resort can accommodate up to six people. It features a larger diameter and often includes a built-in therapy seat for focused massage.
Each model comes with a variety of exterior colors and interior liner options. The outer material is typically made of LeatherTex, a marine-grade vinyl that is resistant to UV rays and harsh weather conditions.
How to Install Your Softub Spa
Setting up a Softub is a straightforward process that does not require professional assistance. However, proper site preparation is necessary to ensure the longevity of the foam structure and the safety of the users.
1. Choosing a Location
Select a flat, level surface that can support the weight of the tub when filled with water. A filled Softub can weigh between 1,500 and 3,000 pounds, so a sturdy deck, concrete pad, or compacted gravel base is recommended. Avoid placing the tub on bare dirt or uneven grass.
2. Positioning the Tub
Roll the empty tub to your chosen location and place it on the ground. Ensure there is enough clearance around the tub to attach the HydroMate unit and to allow for easy entry and exit. Make sure the tub is within reach of a grounded 110V outlet without using an extension cord.
3. Connecting the HydroMate
Align the hoses from the HydroMate unit with the intake and return ports on the side of the tub. Tighten the connectors by hand to ensure a snug fit. Do not use tools, as over-tightening can damage the plastic threads or seals.
4. Filling and Powering Up
Place a garden hose inside the tub and fill it until the water level reaches about two inches above the highest jet. Once filled, plug the unit into the outlet and set your desired temperature on the digital control panel. It may take 24 to 48 hours for the water to reach the maximum temperature of 104 degrees Fahrenheit.
Maintenance and Water Care
Maintaining clean water is the most important part of owning any spa. Because Softubs hold a smaller volume of water than large permanent pools, chemical imbalances can happen quickly if the water is not monitored.
Testing the Water: Use test strips at least twice a week to check pH levels and sanitizer levels. The ideal pH range is between 7.2 and 7.8. If the pH is too high or too low, it can irritate the skin and damage the spa components.
Sanitization: Most owners use chlorine or bromine to keep the water free of bacteria. Always follow the manufacturer’s guidelines for dosage, as the foam material can be sensitive to over-chlorination. Many users also opt for mineral purifiers to reduce the amount of harsh chemicals needed.
Filter Care: The filter should be removed and rinsed with a garden hose every two to four weeks. Every few months, soak the filter in a specialized cleaning solution to remove oils and minerals that a simple rinse cannot reach. Replace the filter entirely every 12 to 18 months.
Seasonal Care Tips
Softub Spas are designed for year-round use, even in freezing temperatures. However, if you live in an area with heavy snowfall, ensure that you clear snow off the lid to prevent the weight from damaging the foam core. The heat recovery system will keep the water warm as long as the unit remains plugged in.
If you choose to close your spa for the winter, it is vital to drain it completely. Use a wet/dry vacuum to remove any standing water from the internal plumbing and the HydroMate unit. Storing the tub in a garage or shed will help protect the vinyl exterior from the elements.
To keep the exterior looking new, clean the LeatherTex vinyl with a mild soap and water solution. Applying a vinyl protectant once a season can help prevent the material from fading or cracking due to sun exposure.
Conclusion
Softub Spas provide a practical and efficient way to enjoy the benefits of hydrotherapy without the permanence or expense of a traditional hot tub. Their lightweight design and simple electrical requirements make them an accessible option for many different types of homes. By following a regular maintenance schedule and properly preparing your site, you can enjoy a reliable and relaxing spa experience for many years.
