4 Foundation Types for Hot Tubs

You’ve made your purchase, and you’re excited to start enjoying your hot tub. Before delivery, don’t forget one very important step: Make sure you have the proper foundation on which to install it. Here are four hot tub foundation ideas that will ensure your hot tub is positioned correctly and looks great.


A concrete surface is an excellent base for your hot tub as this material is extremely sturdy and long-lasting. If you have an existing patio made of concrete bricks, make sure it’s in good condition and is level (not angled for drainage). A customized poured concrete pad is an even better choice. Having a single slab rather than multiple blocks will increase the durability, and you can customize the size and shape to fit your spa’s specific dimensions. 


Decks can be an easy choice, as they are already level and solid. Most well-built decks can handle a hot tub, but make sure you have proper supports, as a fully loaded hot tub can weigh more than 4,000 pounds. You should always have an existing deck inspected before your hot tub is installed. 

Gravel or Crushed Rock

Gravel is a simple and inexpensive spa base, provided it’s used properly. You’ll need to do some digging to accomplish this foundation. Grass and topsoil should be removed and the ground should be level. You can then add the gravel; pack it down as much as possible and level it. For a more polished look, add patio pavers.

Spa Pad

You can purchase a prefabricated hot tub foundation pad that will rest over a spot in your backyard and keep your spa level. You will still need to clear the area of grass and topsoil, but laying a spa pad is an easy way to get a luxurious-looking base.

Everything You Need to Know About Spa Pumps

Are you in the market for a hot tub or spa pump? Pumps are an essential part of your spa, and there is more to them than you might think. Most Jacuzzi® Hot Tubs have two separate pumps, for circulation and jet power, and select models even have up to three jet pumps! These power the jets by pulling water through a filter and then pushing it out the jets in our signature 50/50 air-to-water ratio. Circulation pumps pull water through a separate filtration system, treat it with UV light, heat it up, and push perfectly warmed, crystal-clear water back into the hot tub. Here are some elements you’ll want to consider when shopping for the perfect spa pump. 

Jet Power

The horsepower controls the pressure of the water coming out of the jets. The more jets you have, the more horsepower you will need. Keep in mind that higher horsepower doesn’t always mean a better spa; jet placement and design are important to consider. In hot tubs with more than one jet pump, there is a diverter knob that allows you to redirect the jet power to particular seats. Jacuzzi® Hot Tubs use top-of-the-line engineering to create cost-effective systems with flow control and the right amount of jet power for each hot tub model.


Traditional spa pumps are one-speed or two-speed, depending on how many levels of jet power the spa has. If your spa uses the same pump for circulation and jet power, you’ll want a two-speed pump that you can set at a very low level to circulate the water when the tub is not in use. However, many modern tubs have separate circulation pumps to keep the water sparkling. For the newest technology in spa pumps, consider a variable-speed pump, which uses a type of motor similar to that used in hybrid cars. These are typically quieter and produce less heat and vibration, resulting in reduced wear and tear and a longer lifespan.

Energy Use

With growing concern about energy use in all facets of life, Jacuzzi® Brand has been producing a variety of new hot tub features. First-class insulation, LED lights, and expertly engineered jets are just some of our latest design innovations. Programmable circulation pumps filter the water efficiently, and some even reduce energy usage by transferring motor heat to the water. For jet power, variable-speed pumps are a great option for energy savings—because they can be set to any speed, they are more efficient than set one- or two-speed pumps. Check our website for more about energy-saving features on Jacuzzi® Brand spas and hot tubs.

By learning a little about spa pump parts, you’ll be able to buy the best one for your hot tub. Purchase Jacuzzi® Genuine Parts to ensure your pump continues to operate at peak performance and that you don’t void your warranty. Your local dealership can put you in touch with an authorized service technician.


What Is Water Alkalinity and Why Does It Matter?

Water alkalinity is a measure of your water’s ability to neutralize acids. It’s an important part of balancing pH levels and is often called a “buffer” because it helps the water resist drastic changes in pH. Unbalanced alkaline levels can have an adverse effect on your hot tub’s appearance and even affect your skin. Read on to learn more about this important part of hot tub water care.

Why It Matters

Low alkalinity is the more serious of the two extremes. It can cause rapid fluctuations in pH, because the water can’t as easily counteract the effects of acids, like acid rain or naturally occurring minerals. Such an environment has a cascade of effects on your hot tub’s appearance: it can damage and erode its surfaces, while also corroding metal parts, a perfect storm can result in unsightly stains. Low-alkaline water also won’t be able to balance the amount of phosphates, which feed algae, resulting in water that is green.

Too-high alkalinity can also result in green water, for a different reason: It can reduce the effects of the chlorine you use to keep algae under control. And while low alkalinity causes erratic pH, high alkalinity typically causes stubbornly high pH levels that are very difficult to lower. A high-pH environment can result in high calcium levels, making the water cloudy or causing “scale,” a hard, crusty mineral build-up.

Both high and low alkalinity at their most extreme can cause burning eyes and itchy skin. At less acute levels, water alkalinity can irritate the top layer of skin, causing it to feel dry and making it more susceptible to damage.

What You Can Do

Total alkalinity should be kept at 80–120 ppm. To raise low alkalinity and stabilize your pH, use sodium bicarbonate over a period of time. To lower high alkalinity, you can use a pH reducer or muriatic acid. Better yet, prevent mineral build-up and cloudy water from the start with ProtectPlus, which inactivates damaging minerals. For green water, use a shock treatment and work on restoring your hot tub’s overall pH balance. Once balanced, use a non-chlorine stabilizer like brominating tablets to control algae and bacteria.

As a general rule, always rinse off after your dip using warm water, not hot, and patting your skin dry instead of rubbing. See “How to Keep Your Skin Healthy After Soaks” for more tips on skin care.

Monitoring alkalinity in the water is an important part of hot tub maintenance. Unbalanced alkaline levels and pH can decrease the life expectancy of your hot tub and lead to costly issues down the road. Don’t skip this significant water maintenance step.

Hot Tub Maintenance 103: Keeping Water Clean

There’s nothing better at the end of the day than sinking into your hot tub and letting everything else melt away. While the buoyancy, heat, and circulation do a lot to soothe aching muscles and ease stress, relaxation actually starts with this first basic step: crystal clear water.

For the latest blog in our  hot tub maintenance series, we’ll provide you with helpful tips on water care to ensure your soaks always begin at their best:


Balance is key when maintaining the harmony of your home spa. Test your water with a kit or strips at least once a week to gauge total alkalinity and pH. The results will determine whether you need to use our Spa pH Up or Spa Alkalinity Down products to balance the levels in your tub.


Keeping your water pure begins with keeping it sanitized. Chlorine and bromide, used properly, will leave your tub smelling and looking fresh. Our CLEARRAY® UV-C uses ultraviolet technology to help reduce the need for these hot tub chemicals and maximize the efficiency of your water treatments.


Proper upkeep can extend the life of your equipment and the cleanliness of your hot tub. Make sure to clean your filters once a month. Our Filter Flosser filter cleaner and filter debris bags simplify the process and are easy to use.


Replacing failed or struggling spa equipment helps to keep your unit in good working order. Maintenance is easy and affordable, which saves you money in the long run in addition to ensuring a safe, hygienic environment for your family.


Draining and refilling your hot tub every few months will make it easier to balance PH, keep your filters clear, and minimize the use of sanitizers. Refreshing your water has the added benefit of allowing you to wash your home spa shell, so the whole tub is shining and spotless.


A spa cover will guard your investment against weathering by the sun or rain. It also helps to keep your water clean, bright, and sanitary. Maintaining your cover is as important as maintaining your hot tub, so be sure to scrub and rinse it to keep it in top condition.

Hot Tub Maintenance: 101

Hot Tub Maintenance Is Not Nearly as Hard as You May Think

hot tub maintenance

If you have never owned a hot tub, the thought of maintaining one may seem overwhelming. But in reality, maintenance is rather simple!

A few minutes a week are all you need to maintain your hot tub so you and your family can enjoy using it for years to come. Hot tub maintenance doesn’t require a lot of skill, but you do have to know what to do and when to do it. From the exterior shell to the water chemistry, here are some tips for proper hot tub maintenance:


Spring Cleaning Your Hot Tub

Your Jacuzzi® Hot Tub helps you take great care of your body, so it goes without saying that it should be well maintained, too. As the spring-cleaning season approaches, don’t forget to include your hot tub on your To Do list. Here’s a checklist of what we recommend tidying up in the next few months in regards to your spa and its accoutrements:

Clean the Cover

Your hot tub cover is exposed to the elements year-round, and as such needs occasional care. A cleaning every month (not just every spring!) will keep your cover looking good and help it last longer. First use a nonabrasive cleaner like Jacuzzi® Cover Conditioner, then wipe the cover down with a damp cloth or sponge before rinsing with warm water. Got extra grime? Allow the cleaner to work its magic for a few extra minutes before wiping it down.

Check Filters

Spraying off your hot tub’s filters each week is a great habit to get into, but a faucet or hose can’t completely rid your filter of dirt and debris. This April, replace your filter if you haven’t done so. If you’re recently replaced your filter, now’s a good time to give your filter a dip in a Filter Cleaner to really clear it out. In general, we recommend that filters receive this overnight treatment monthly, but be sure to check your filter instruction manual before soaking your filters; some varieties should not be soaked due to risk of disintegration.

Clean Pillows

The cleaner that you use to sanitize the shell of your Jacuzzi® Hot Tub can also be used to clean any pillows you might have. When cleaning your pillows with a water-filled hot tub, spray the cleaner onto a cloth rather than directly onto the pillow. Wipe the pillow gently with the rag, then wipe again with a fresh wet rag.

Clean Steps

If you have single- or double-steps leading up to your hot tub—whether they’re plastic, mahogany, teak or synthetic wood—it’s important to keep them clean. Wipe the steps down with a damp cloth after every few hot tub sessions and give them a good scrub this spring.

Drain and refill your water

Get into the habit of draining and refilling your hot tub water every three to four months, or more depending upon usage. In other words, this task should definitely make it on your spring-cleaning list! First completely drain the water, then wipe the tub’s surface with a damp cloth or all-purpose cleaner. Carefully inspect your spa for wear and tear before using a hose with an attached filter to refill the tub. Be sure to take your time balancing chemicals based on directions on the bottle.

This spring, set aside some time to make sure your spa is spic and span. You’ll keep your Jacuzzi® Hot Tub running smoothly for years to come by regularly maintaining its exterior and accessories. You can find Jacuzzi® Brand hot tub cleaning products at your local dealership. Just remember to explicitly follow all instructions included with any cleansers you use!

Hot Tub Pre-Installation Checklist

Jacuzzi® Hot Tubs are easily installed, but there are a number of things that you should expect prior to the arrival of your new relaxation station. Here are some things a reputable hot tub dealer will help you figure out before your spa arrives:

Does your city or county have any requirements, like a gate, fence, or steps that you need when you have a hot tub on your property?

Some cities have municipal codes in place to protect children, such as obligating owners to install gates, fencing, or other such barriers to deny access to unsupervised children. Your local Jacuzzi® Hot Tub dealer will have that information ready for you and help guide you through the installation process.

How much room do installers need to get your hot tub into your yard?

Installation of your new hot tub requires a completely unobstructed route to ensure that the unit does not incur any damage along the way. Double check all gates and entranceways to ensure sufficient clearance. Determine ahead of time the route that the installer should take when your Jacuzzi® Hot Tub arrives. Keep an eye out for objects that might hinder the delivery team in any way, and remove those obstacles in advance of the installer’s arrival. Also inspect your yard for any overhanging branches, rain gutters, or protruding electrical meters that might impede the installation process. Are there more than 6 consecutive stairs without a landing in your delivery route? If so, you must consult your Jacuzzi dealer prior to delivery to make adequate preparations.

Indoor or outdoor? On a deck or on the ground?  Grass or gravel underneath? Does the location you’ve chosen make sense?

Due to the heft of the hot tub, water, and happy bathers inside, it’s of the utmost import that the foundation upon which your unit sits is completely level and capable of equally distributing the weight that rests upon it. Your hot tub dealer will help you decide which type of foundation is best for you.

What are the electrical requirements?

Jacuzzi® Hot Tubs that are installed in the United States must meet the wiring specifications established by the National Electric Code (NEC) as well as any other state or local codes. Any circuitry must be installed by a professional electrician and receive approval an appropriate inspection official.

Owning a Jacuzzi® Hot Tub can instantly increase your quality of life by providing a relaxing hydromassage and a variety of other health benefits. Before your hot tub arrives, check out this video to see how you’re the installation may go.

The Different Stages of Filtration

Filtration is an essential component in keeping any hot tub clean. And the purification process in Jacuzzi® Hot Tubs makes maintenance simple so you can spend more time enjoying your hot tub.

Here’s a look at the five different stages of the purification process in Jacuzzi® Hot Tubs:

The Five Stages of the Jacuzzi® Water Treatment Process

CLEARRAY illustration

  1. The whole process starts with the ProClarity™ filtration system (exclusively on J-400™ Collection models). This filter traps tiny particles that slip past the other filters, ensuring only the cleanest, clearest water in your Jacuzzi® Hot Tub.
  2. Next, to prevent harmful bacteria from accumulating, the ProClear™ Filter (J-300™, J-LX®, and J-400™ Collections) clarifies water even when the jets aren’t powered on, giving you peace of mind when the pumps are off.
  3. The Surface Skimmer (present in the J-200™, J-300™, J-LX® and J-400™ Collections) works in conjunction with the ProCatch™ Filter Bag (J-300™, J-LX® and J-400™ Collections only) to gather oil, grease, and sizable bits of debris before they create a less-than-optimal environment.
  4. Then a pleated cartridge filter works with your hot tub’s hydromassage pump to rid your water of any remaining impurities.
  5.  And the last line of defense when keeping your water safe is the CLEARRAY® Purification System, included standard in every Jacuzzi® Hot Tub model. This system employs pathogen-eliminating ultraviolet light to ensure a constant flow of clean, clear water. CLEARRAY® also reduces the amount of sanitizer required by your Jacuzzi® Hot Tub, making maintenance that much more effortless.

To further maintain an ideal experience in your Jacuzzi® Hot Tub, use testing strips to ensure that chlorine levels are within an acceptable range. If the chemicals drop to a dangerously low level, bacteria and other germs will have the opportunity to not only survive, but thrive. Remember to keep your Jacuzzi® Hot Tub functioning at peak performance with Jacuzzi® Genuine Parts and Accessories, available online or at your local Jacuzzi® dealership.

You’ll Never Think Hot Tubs are Gross Again


While your Jacuzzi® Hot Tub will remain clean and sterile with proper cleaning, it can be difficult to shake some of the stories you hear about hot tubs and sanitation. Some of these stories may leave you concerned about the cleanliness of your spa. Rest assured that your Jacuzzi® Hot Tub is engineered with easy maintenance and complete safety and sanitation in mind. In short, you’ll never think hot tubs are gross again.

Why Clean Your Hot Tub?

Your hot tub doesn’t just collect the occasional detritus like leaves and insects. Sitting in a cauldron of hot water means things like lotion and oils can collect in the hot tub over time. Without proper sanitation, these items can build up and cause sanitation or health problems.

How to Clean Your Jacuzzi® Hot Tub

Maintain clear, clean water and a properly functioning hot tub by using Jacuzzi® Genuine Parts and Accessories. Jacuzzi® Hot Tubs also feature up to five stages of water treatment processes. It all starts with the ProClarity™ filtration system, which catches tiny particles to ensure clear, clean water. The ProClear™ filter, available on the J-300™, J-LX®, and J-400™, then clarifies the water even when your jets aren’t on. Next, the ProCatch™ bag cleans the surface. Finally, a pleated cartridge works in conjunction with the hydromassage pump to provide the cleanest water possible. You can also monitor the chlorine levels in your hot tub with testing strips to ensure they remain at proper levels. If the chemicals drop below a certain amount, it becomes easier for bacteria to multiply.

How to Purify Your Water

All new Jacuzzi® Hot Tub models utilize the CLEARRAY® Water Purification System. This top-of-the-line maintenance system uses an exclusive ultraviolet technology in conjunction with the ProClear™ Sanitizer to neutralize waterborne pathogens and reduce the amount of sanitizer you use. This means maintaining fresh, clear water has never been easier. Together, our five-stage filtration system kills off bad bacteria, maintains a consistent pH balance, and gives you soft, clean water.

All hot tubs will develop some grime and bacteria if they are not properly cleaned. Your Jacuzzi® Hot Tub comes with built-in maintenance routines to ensure your water and your hot tub are clean and safe to use.

How to Prep Your Hot Tub for Winter

Your hot tub is an outstanding addition to your home and family, and proper maintenance will ensure you get to enjoy it for years to come. This maintenance includes making the necessary adjustments to keep your spa operating through the cold winter months or, alternatively, shutting it down during the cold months. We’ll discuss both possibilities below.

Closing Down for Winter

Hot tub owners often report that they most enjoy using their spas during the winter. However, if your area is bracing for severe inclement weather or you’re leaving town for an extended period of time, you may wish to shut down your spa entirely.

  1. Power Down

You’ll be emptying your spa of water and performing additional maintenance

on it, so shut off the heater and turn off the spa.

  1. Empty the Spa

Drain your hot tub of all water. Empty the air blowers, if your spa is

equipped with these.

  1. Clean Filters

Remove your filters and place them in a cleaning solution. You’ll want to keep them in a dry place for as long as they’re out of the hot tub. Take this opportunity to clean the filter basket, as well.

  1. Loosen Fittings

If your pump housing has drain plugs, open them. You may wish to rent or purchase a shop vac to remove additional water left inside these fittings.

  1. Blow Jets

Water can get trapped in your jet plumbing and damage your hot tub if it freezes. Make sure this is drained, whether manually or by a shop vac.

  1. Clean the Shell

Your hot tub is empty, so give the entire basin a good scrubbing with a spa cleanser.

  1. Cover Your Tub

Place your cover over your hot tub and lock it down. It will protect your spa during the winter.

When spring arrives, you can refill your hot tub and begin enjoying it again.

Operating Your Spa in Winter

If you are concerned about the cost of operating your spa and its heater in the winter, you can relax; if properly maintained, keeping your hot tub operating is surprisingly cost-efficient. Here are a few simple steps you can follow to prepare your hot tub for winter.

  1. Drain/Clean Tub

You’ll still want to give your spa a cleaning session. Drain your hot tub and give it a thorough scrubbing, including the vents and filters.

  1. Refill Your Spa

Fill your hot tub with water.

  1. Activate Freeze Protection

If you live in a very cold climate, run your hot tub in F3 “Standard” mode. A sensor will monitor the climate and periodically run the pump when the temperature drops below a certain level, preventing anything from freezing.

    1. Keep Your Spa Covered

If you aren’t using your hot tub, keep the cover firmly on it. This will keep the heat in, preventing you from running the heater continuously and saving you money in the long run.

There’s nothing quite like watching snow drift down from the comfort of your spa. Why not keep it operating in the winter and enjoy it?

Now that you know how to maintain your spa through the winter or how to properly shut it down, you’ll be able to properly manage its care. As long as you look after it, your hot tub will function optimally.

Dispelling 3 Common Myths about Hot Tubs

Debunking some of the common myths associated with hot tubs can help you choose the right spa and keep it well-maintained for a long time. Here are three common misconceptions all prospective and current hot tub owners should know about.

Purchasing myths
A higher number of jets and horsepower equates to a higher quality spa.

 Whether it pertains to jets or horsepower, more doesn’t always equal better. Jacuzzi® Hot Tubs come in a variety of shapes and sizes, with varying numbers of jets. The real quality and ultimate hydromassage benefit is gained by the placement, type, and size of the jets. More jets don’t always equate to more comfort, but it almost always means higher operating costs. Furthermore, if the pump size remains the same and is forced to push air/water at lower volumes through the jets, this could lead to inferior performance.  Horsepower quantity is based mostly on powering the number of jets the spa has and can also contribute to higher energy bills.

Maintenance myths
If you have an ozone system, you don’t need to add chemicals to your spa to keep it clean.

Ozone reduces, but does not completely eliminate, the need for spa chemicals. The ozone system in your spa can help oxidize some contaminants, but it’s not a one-step solution for cleaning the water. You still need chlorine or shock to fully sanitize your hot tub. Make sure to properly test the water and use the appropriate chemicals to keep it clear, clean, and safe. Learn more about common hot tub maintenance myths .

Cleaning myths
Cleaning your spa with bleach is the best way to disinfect it.

Truth: Many people use household bleach as a spa or pool sanitizer, even though it can cause damage to the finish of the hot tub’s interior and filter, and can permanently damage the cover. Excessive ozone, chlorine, or bromine levels can also bleach the underside of your spa cover. In addition to draining your water, cleaning your filter, and flushing your spa’s internal plumbing system, try using an all-purpose cleaner  for your hot tub’s surface and cover.
