A hot tub is a significant investment that provides relaxation, physical therapy, and a social space for your home. Whether you are looking for a simple inflatable model or a permanent in-ground installation, understanding the basics of hot tub ownership is essential. This guide covers the different types of hot tubs, how to prepare for installation, and the steps required to keep your water clean and safe.
Types of Hot Tubs
Before purchasing a hot tub, it is important to understand the three primary categories available on the market. Each type offers different benefits regarding cost, durability, and features.
Inflatable Hot Tubs
Inflatable hot tubs are the most affordable and portable option. They are made of heavy-duty PVC or vinyl and can be set up on any flat, sturdy surface. These are ideal for renters or those who want to test the experience of owning a hot tub without a large financial commitment.
Portable (Hard-Shell) Hot Tubs
These are the most common type of hot tub. They feature a molded acrylic shell and are housed in a decorative cabinet. While they are called “portable,” they are heavy and usually require a professional delivery team. They offer more powerful jets, better insulation, and a longer lifespan than inflatable models.
In-Ground Hot Tubs
In-ground hot tubs are often built alongside a swimming pool. They are custom-made from concrete or fiberglass and offer a seamless look for your backyard. These are the most expensive option and require significant construction work, but they add the most value to a property.
Key Considerations Before You Buy
Purchasing a hot tub requires careful planning to ensure the unit fits your lifestyle and your home’s infrastructure. Consider these factors before making a final decision.
- Size and Capacity: Determine how many people will realistically use the tub at once. A four-person tub is standard, but larger families may require a six- or seven-person model.
- Location: You need a level, solid foundation such as a concrete pad or a reinforced deck. Ensure there is enough clearance around the tub for maintenance access.
- Electrical Requirements: Most hard-shell hot tubs require a dedicated 240V electrical line installed by a licensed electrician. Some smaller models, known as “plug-and-play,” can use a standard 120V outlet.
- Budget: Beyond the purchase price, factor in the cost of delivery, electrical work, water chemicals, and the monthly increase in your electricity bill.
Essential Hot Tub Maintenance
To keep your hot tub water clear and safe for soaking, you must follow a regular maintenance schedule. Neglecting water chemistry can lead to bacteria growth and damage to the tub’s internal components.
1. Water Chemistry and Balancing
You should test your hot tub water at least two to three times per week using test strips or a liquid testing kit. The three most important levels to monitor are:
- pH Levels: The ideal range is between 7.2 and 7.8. If the pH is too high or too low, the sanitizer will not work effectively, and the water may irritate your skin.
- Alkalinity: This acts as a buffer for your pH levels. It should stay between 80 and 120 parts per million (ppm).
- Sanitizer: Chlorine or bromine are used to kill bacteria. Follow the manufacturer’s instructions to maintain the correct levels for your specific sanitizer type.
2. Cleaning the Filters
The filter is responsible for removing debris, oils, and lotions from the water. You should remove the filter and rinse it with a garden hose once a week. Every month, use a dedicated filter cleaning solution to break down deep-seated oils and minerals.
3. Draining and Refilling
Even with perfect chemical balance, the water will eventually become saturated with dissolved solids. Most experts recommend draining and refilling your hot tub every three to four months. This provides a fresh start and allows you to scrub the interior shell of the tub.
Installation Steps for New Owners
Once you have purchased your hot tub, follow these steps to ensure a smooth setup process. Proper preparation prevents long-term structural issues.
First, confirm that your chosen site is completely level. A slight slope can put uneven pressure on the hot tub shell, leading to cracks over time. If you are placing the tub on a deck, consult a structural engineer to ensure the wood can support the weight of the tub when filled with water and people.
Next, arrange for the electrical hookup. This should always be done before the hot tub is filled with water. A professional electrician will install a manual disconnect box (GFCI) within sight of the hot tub to meet safety codes.
Finally, fill the tub by placing a garden hose into the filter compartment. This helps prevent airlocks in the plumbing system. Once filled, turn on the power, add your initial chemicals, and wait for the water to reach the desired temperature, which usually takes 12 to 24 hours.
Safety Tips for Hot Tub Users
Safety is the most important aspect of hot tub ownership. Following basic guidelines ensures that everyone can enjoy the spa without risk of injury.
- Temperature Limits: The water temperature should never exceed 104°F (40°C). Most modern tubs have a digital thermostat that prevents the heater from going higher.
- Supervision: Children should never be left unattended in or near a hot tub. Ensure the cover is locked when the tub is not in use.
- Hydration: Hot water causes the body to sweat. Drink plenty of water while soaking to avoid dehydration or dizziness.
- Limit Soak Time: Beginners should start with 15-minute sessions. Prolonged exposure to high heat can lead to heat exhaustion.
Energy Efficiency and Cost Savings
Running a hot tub can increase your monthly utility costs, but there are ways to minimize the impact. Use these strategies to keep your energy bills manageable.
Keep a high-quality, insulated cover on the tub whenever it is not in use. Most heat loss occurs through evaporation at the surface of the water. A well-fitting cover traps the heat inside and reduces the workload on the heater.
Check the cabinet insulation. If you live in a cold climate, adding extra foam insulation inside the cabinet can help retain heat. Additionally, keeping the temperature consistent is often more efficient than turning the heater off and on, as the unit uses the most energy when heating water from a cold state.
Conclusion
Owning a hot tub provides a convenient way to relax and improve your overall well-being at home. By choosing the right model for your space and committing to a simple maintenance routine, you can enjoy a clean and safe spa for many years. Remember to test your water regularly and keep your filters clean to protect your investment.
