With the rising cost of new spas and hot tubs, buying a used model may be an economical way to live the hot tub dream. In this used hot tub buying guide, we’ll cover some basics to look out for to help you make an informed decision on what to buy.
Today’s spas come in a variety of styles, colors and features, but can require different electrical service. Smaller and entry-level hot tubs tend to run on 110/115 volts and would plug into an outlet, while other models are the 220 volts, and are hard wired. Knowing what you have available from your home’s electric service is important, as well as the costs associated with running an electric line to your spas location.
Many spas need a hardwired 220-volt circuit, 50 or 60 amps. These models usually have multiple pumps and better heating capabilities than lower volt hot tubs. A spa running at 220 volts is the best choice because you will get consistent heat regardless of how many pumps are running. The only true way to enjoy the spa life.
Other models, considered Plug and Play, can be plugged into your 3-prong outlet and typically draw 15-20 amps. These models are a cost-effective way to hot tub, but there is an important limitation: anytime you run the high-speed pump and/or a blower, your heater turns off. There is not enough power to run the heat, the high pumps, and blower(meaning you can’t run the heat while the jets are on high). These models also heat at a lower rating and take longer to build and maintain heat.
Owning a spa is not just soaking and enjoying. This large item in your yard will increase your electric bill some. Depending on how you have your spa set, it can cost $25-$50 per month in cooler times, and in our hot Florida summers, likely under $20.00 per month. Another consideration are chemicals for sanitizing and balancing your spa. We would estimate $350-$500 per year. Lastly, filters should be replaced every year for optimal filtration. They can range from $15.00 – $125.00+ per filter.
Make sure you consider the size of your hot tub and its placement. Hot tubs need a level surface to rest on. The surface should also be strong and durable to support its weight. With today’s spas averaging 300-500 gallons and a weight of 8.34 pounds per gallon, you can get a feel for the kind of weight you will need to support. Decks should be reinforced, and concrete pads must be 4-6” thick. Never put your spa on the grass or dirt.
Since many models can weigh up to 900 lbs dry, you will need to think about transportation. Having your new to you hot tub delivered safely to your home is very important. Sure you could get a flat bed trailer, some pvc pipes, and friends, but the chances of damage are great. Professional hot tub movers use a spa sled or spa dolly moving system to get your hot tub to your home in one piece. Hiring a professional can cost $250-$400 depending on delivery difficulty and the distance between the pick up and drop off point.
You’ve decided to pull the trigger and start your search for a new spa. Here are some do’s and dont’s to help you make the right choice when buying a used hot tub.
Models that are older than 15 years tend to have parts that are obsolete, or have outdated features. If possible, try to get a model 5 years old or newer. Most tubs will need work when they hit 8-10 years old, but this does depend on the previous owners care and maintenance
Hot tubs with real wood paneling tend to be older models that you should stay away from unless they were stored inside. These wood paneled spas tend to have a wood base that rots. When you go to lift the spa it is separated from the frame. This is a nightmare – time for some carpentry. Strive for a model that has a plastic pan style base, pressure treated or steel frame, and maintenance free composite paneling. These models tend to last longer and do not need yearly maintenance to their finish.
Spas made in China tend to have inferior parts and are a nightmare to deal with for parts and warranty. The parts they use are reversed engineered and therefore do not have the same reliability as North American spa parts. These tubs tend to fail quickly and need to be retrofitted with new controls systems within the first few years.
Blow Up Spas are low budget spas that have an attractive price tag, but are not a great option used. These plug in spas are usually sold at big box stores or online and do not have serviceable parts. Once they break it’s time for a new one.
•Always look at a hot tub filled and running. This way, you can verify that all components are functioning correctly, and that the jets have good power. Tubs that “were working great the last time we had it on” should not be purchased without seeing it running.
•Check the condition of the spa cover. If the cover is very heavy, falling apart, or missing altogether you will need to buy a new one right away. Click here to read more about why you need a cover for your hot tub.
•Check under the hood: Although a hot tub can seem to be running well from the outside, it’s always important to know what’s going on behind the paneling. If possible, remove the skirting panels and check the plumbing, pumps and wires to give yourself an idea of any issues or problems. Things that are not good to see are leaking and rusted pumps, broken wires, and leaking jets. These indicate repairs that will be needed, and you would want to factor this into your price negotiations.
•Are all the jets intact? Make sure the spa has most of its jets intact. Missing jets means it is time for replacements. Depending on the brand, this can get costly.
•Working buttons and a legible screen on the topside control panel is important. That panel is the main communication port between you and the spa.
•Check for cracks or blisters: Spa shells can get cracks if they are not properly supported. These cracks may not always leak but can spread and get worse. Blisters are spots where the acrylic shell and the fiberglass or resin backing has de-laminated, causing an air pocket. Try to avoid models with shell damage as this is the main vessel of the hot tub model and most important.
Options are nice but simple is better. We find the more options a hot tub has the more issues and sooner.
Options like ozonators, LED lighting and salt chlorinators are great additions to your spa experience. They make sanitation easier, and provide a bit of ambience in your personal oasis.
Options to stay away from are stereos, subwoofers and televisions. These novelty items were popular at a time but have become obsolete with today’s technological advances. A simple blue-tooth speaker and your smartphone will give you better music selection than a spa stereo.
