What Is a Swim Spa or All-Season Pool?

A swim spa, also called an all-season pool, is a combination of a swimming pool and a hot tub. It uses a current-controlled swim lane so you can swim, exercise, or play, and it pairs that with heated seating and hydrotherapy jets for relaxation and recovery.

Swim spas are built to be used year-round. Built-in heaters, strong insulation, and quality covers keep the water warm even in cold weather, so you get a usable pool in months when a traditional pool would be closed. They’re also smaller and easier to maintain than a traditional inground or above-ground pool, which makes them a practical option for homeowners who want more flexibility in a compact footprint.

How Do You Choose the Right Swim Spa?

Choosing a swim spa comes down to a few key decisions.

- How do you plan to use it? Fitness, recreation, or a mix of swimming and hydrotherapy?

- How much space do you have, and will it go indoors or outdoors?

- How many people will use it regularly?

- How hands-on do you want to be with maintenance?

- What’s your budget for both the purchase and ongoing operation?

Start with purpose (fitness, recreation, or dual-temp), then narrow down size, jet system, brand, and features that fit your backyard and budget.

Why Choose a Swim Spa Over a Pool or Hot Tub?

Swim spas solve a few problems that traditional pools and hot tubs don’t.

For exercise, they give you a current-controlled swim lane that provides an effective workout in a much smaller footprint than a full pool. For entertaining, they double as a social hub with seating and jets. For year-round use, built-in heating means you’re not closing down in winter. For maintenance, the smaller water volume means less chemical use and easier upkeep than a traditional pool.

They also fit tight or narrow spaces where a full pool wouldn’t work, and they can be moved if you relocate, unlike an inground pool. For fitness enthusiasts, families, seniors doing rehabilitation or low-impact exercise, and busy professionals who want a quick daily reset, swim spas cover a lot of ground in one unit.

What Sizes Are Available for Swim Spas?

Swim spas typically range from 12 to 19 feet long. The size you pick should line up with how you plan to use it.

For entertaining, look at 16 feet and larger for more seating capacity. For serious swimming, 14 feet and larger gives you enough space to move. For a blend of recreation and exercise, 13 feet is a solid middle ground and it’s also the most popular size among buyers.

Tank height typically ranges from 48 to 60 inches. Most users do well with 48 to 54 inches, which balances comfort for seating and keeps the water line below the shoulders for exercise. Taller users (over 6’4″) or those focused on entertaining may prefer 54 to 60 inches, though higher water lines can limit exercise effectiveness.

Swim spas have a higher water depth than traditional hot tubs, so you get a deeper soaking experience along with room to swim.

What Are the Different Types of Swim Spas?

Swim spas come in three main configurations to match how you plan to use them.

Fitness models are built for serious training, with stronger current systems, longer swim lanes, and features designed for swimmers, triathletes, and anyone using the spa as a home gym. Seating is usually minimal to maximize swim space.

Recreation models focus on family use and play, with lighter current systems and more open space for swimming, water aerobics, and hanging out. These typically include four corner seats and a small swim lane.

Dual-temp models split the spa into two zones so you can swim in cooler water on one side (as low as 85 degrees) and soak in a warmer hot tub zone on the other (up to 104 degrees). Dual-temp is typically only available in 17-foot and larger models, with a 7-foot hot tub area and a 12-foot swim area. These require two separate electrical hookups totaling around 100 amps.

What Seating Options Should You Consider?

Seating varies significantly by model and length, and it affects both how the spa feels and how usable it is for your main purpose.

Shorter swim spa models typically include bench seating, which works well for entertaining but takes up space that serious swimmers would rather have open. If swimming and exercise are your priority, look at open pool tank models that maximize maneuverability in the water.

Longer swim spas (16 feet and up) often give you the best of both worlds: ample swim space plus multiple seating areas for relaxation. Dual-temp models take this further by dedicating separate zones to each activity.

Before buying, sit in the spa at the showroom with everyone who’ll use it. Check that there’s elbow room, the neck aligns with the water line, and legs can stretch out comfortably in lay-down seats. If you’re unsure, ask about a wet test. If you’re not comfortable dry, you won’t be comfortable wet.

What Are the Best Swim Spa Brands?

Galaxy carries the top brands in the industry, including Jacuzzi, CalSpas, and Hydropool.

Jacuzzi swim spas are engineered to be among the most energy-efficient in the world and use PowerPro AX jets that combine power and buoyancy for a smooth swim current. Plus, Jacuzzi’s heritage in hydrotherapy make it the most therapeutic brand.

CalSpas offers a full Swim-Pro lineup that works for beginners, health enthusiasts, and professional athletes, giving you a complete aquatic gym in your backyard.

Other widely recognized top brands include Endless Pools, Artisan Spas Tidal Fit, and Michael Phelps Signature Swim Spas by Master Spas. The top brands have been in business for decades, have proven warranties, and deliver better performance, lower energy costs, and longer lifespans than generic or imported brands.

Why Does the Dealer Matter as Much as the Brand for a Swim Spa?

A swim spa is a long-term investment that can last up to 20 years. Over that time you’ll need service, chemicals, filters, maintenance help, and accessories, and the dealer is who you’ll rely on.

A few questions worth asking before you buy:

1. How long has the dealer carried their brands?

1. Do they have an in-house service and install team, or do they subcontract?

1. Do they carry multiple brands so you have real options to compare?

1. Do they stock chemicals, filters, and parts locally?

1. Are they open year-round, not just seasonally?

Be cautious about buying from traveling sales events at Home & Garden shows, state fairs, or expo road shows. You may save some money on a generic brand with no local presence, but you’ll pay for it at the first service issue. Top brands also choose their dealers carefully. You’ll see the top names in almost every metro city because the manufacturers want strong local partners keeping their customers happy.

How Do Swim Spa Jets Work?

Jets are what create the swim current, and the type of jet system significantly affects the swim experience.

- Round jets are the basic option and are cheaper, but they tend to push your body left or right rather than giving you a smooth current to swim against.

- Oval or river stream jets align better with your body and reduce that side-to-side push, though there’s still some turbulence.

- Accuflo jets flatten the current for stronger, steadier resistance and are a meaningful upgrade from traditional oval jets.

- PowerPro AX jets, used by Jacuzzi, combine power and buoyancy to create an ideal current for walking, jogging, or swimming. They’re designed to improve swim technique and feel smoother than basic jets.

Propulsion jet systems, popularized by Michael Phelps Signature Swim Spas, use powerful circular jets that provide strong propulsion, though the current can feel inconsistent because of how the propulsion system cycles.

How Do Pumps Affect Swim Spa Performance?

Pumps drive water circulation and jet power, and the number and distribution matter.

A 13-foot swim spa usually has 2 to 3 pumps. Larger 14-foot and up models often have 3 to 5 pumps. More pumps generally mean more power, which improves both the swim current and the hydrotherapy experience.

Some pumps are dedicated to the swim side and others to the hydrotherapy side. Larger models with more swim jets use additional pumps to keep water flow strong enough for serious swimming.

Look for swim spas with programmable pump levels so you can tailor the current to your activity, whether that’s a light jog or a hard swim interval. Also pay attention to hydraulics and engineering. Well-designed hydraulics let smaller pumps deliver more volume, which means better efficiency, longer pump life, and lower energy costs.

What Sanitization Options Are Available for Swim Spas?

Swim spas need significantly less chemical than a traditional pool because of their smaller volume and insulated covers, but they still need a sanitization system to keep the water clean.

Ozone is one of the oldest options, using ozone gas to oxidize contaminants. Ozonators typically cost $150 to $500 and last about 3 years. They’re not rated as primary sanitizers, so you’ll still need some chemical upkeep, but they reduce it significantly. Nearly every major brand offers an ozone option.

Saltwater chlorination uses salt to generate chlorine automatically. It’s popular and easy to use, but the small volume of a swim spa means salt can corrode metal components over time, and the generated chlorine can still cause skin dryness and eye irritation for some users.

UV sanitization uses ultraviolet light to neutralize bacteria and viruses by disrupting their DNA. UV is EPA-recognized as a sanitizer and requires only 1 ppm of chlorine, making the water feel almost chlorine-free. It also reduces chemical use and eliminates the odors associated with ozone or salt.

The latest systems combine UV and ozone for maximum sanitation. This premium option is offered by CalSpas, Jacuzzi and some others at an additional upgrade cost.

How Does Filtration Work in a Swim Spa?

Filtration keeps the water clean by continuously removing contaminants. Combined with your sanitization system, it’s what makes the water safe and inviting.

Most swim spas use either standard cartridge filters or commercialized pressure filters. The number and size of filters matter. Larger total filter square footage means more water cleaned per cycle and better water clarity. The total filter square footage is usually the best single indicator of cleaning capacity.

How Are Swim Spas Constructed?

Swim spa construction varies by brand and affects durability, weight, and long-term reliability.

Pressure-treated lumber framing is the traditional method and can last up to 50 years. It’s similar to how homes are built and provides a sturdy, time-tested foundation.

Galvanized steel framing is newer and offers precise cutting and easier cabinet adherence. Steel-framed models tend to weigh more but are becoming more common in modern swim spas.

Plastic-framed spas exist but generally lack the strength and thermal resilience of lumber or steel. They don’t hold up as well to hot and cold cycling or to the weight of a fully loaded spa.

When comparing construction, ask how many spas the manufacturer makes annually, where they’re made, whether they hold any patents, whether parts are proprietary or generic, and whether the bottom of the spa is protected from the elements. These answers tell you a lot about long-term quality.

How Does Insulation Affect Energy Use?

Insulation is one of the biggest factors in monthly operating costs. A well-insulated swim spa should cost less than $100 a month to run, depending on climate and usage.

Full foam insulation is the original and most effective method. It fills the cabinet with foam around all the plumbing, giving you the best energy efficiency and sound insulation. It takes slightly more effort to access plumbing for repairs, but trained technicians handle this routinely.

Partial foam insulates the plumbing lines but not the full cabinet. These are often paired with eco-wrap or insulation boards to improve efficiency. They’re slightly less energy-efficient than full foam but give service techs easier access during repairs.

No-foam swim spas are rare and generally the least efficient. They’re cheaper upfront but have higher monthly costs, more noise, and a higher likelihood of leaks.

Shell thickness and cover quality also add insulation value on top of the cabinet insulation.

How Much Does a Swim Spa Cost?

Swim spa pricing typically ranges from $15,000 to $50,000 or more, depending on size, jet system, brand, and features.

Recreation models at the smaller end are the most affordable. Fitness and dual-temp models with advanced current systems sit at the higher end. Premium features like touchscreen controls, UV-ozone combo sanitization, and smart app integration add to the price.

Beyond the purchase, plan for electrical work, a concrete pad, delivery (and potentially crane service), water to fill, chemicals, and accessories like cover lifters or steps.

Your Galaxy design consultant can walk you through a full quote that includes everything, so there are no surprises later.

Where Should You Place Your Swim Spa?

Swim spas can go indoors or outdoors, depending on your space and preferences.

Put the spa somewhere easy to access. If it’s a hassle to get to, you’ll use it less. Leave enough space for steps (typically around 4 feet), cover lifters (standard cover lifters need about 18 inches on each side), and any seating or bar consoles you want nearby.

The foundation needs to be firm and level. For swim spas, a 6-inch concrete slab reinforced with rebar is the standard requirement, with a slight slope for drainage. Gravel and other loose materials typically void the manufacturer’s warranty.

If you’re installing outdoors, consider sun exposure, wind protection, and proximity to the house for easier access in cold weather. If you’re building a deck around the spa, choose materials like composite decking, wood, or pavers that hold up in wet conditions.

What Are the Electrical Requirements for a Swim Spa?

Most swim spas require a 220-volt, 50-amp hardwired electrical line installed by a licensed electrician. Dual-temp models require two separate electrical hookups, typically totaling around 100 amps, to run both temperature zones.

Have the electrician run the line before installation day so the spa can be hooked up when it arrives. Check the whip cord location and length requirements with your dealer. The cord typically enters the spa on either front corner of the control panel side, and you need enough length to reach from the GFCI box to the spa pack inside the cabinet (measure from the GFCI to the corner, then add 6 feet).

Improper wiring can void the manufacturer’s warranty, so confirm your electrician has the correct 3-wire or 4-wire diagram for your specific model. Your salesperson can provide these.

A spa disconnect may also be required, which typically adds $1,500 to $2,000 to the electrical cost.

What Happens on Delivery and Installation Day?

Swim spas are sizable investments, and delivery takes planning.

Swim spas can’t be delivered on their sides like a hot tub, so you need 10 feet of clearance along the entire delivery path. Most swim spas arrive on a 10-foot trailer that tilts to slide the spa off using PVC rollers.

If the spa is going to an elevated location, or if fences, HVAC systems, or other obstacles block the path, a crane may be required. Crane service typically costs $500 to $2,000. Crane service may seem daunting, but it’s very easy and quick to install a swim-spa that way. Galaxy will walk you thru every step of that process.

Check HOA and local ordinances before delivery day. Remote locations may incur mileage charges. Keep a safe distance of at least 10 feet from overhead power lines.

Once the spa is placed, Galaxy will install any cover lifters, steps, or accessories you purchased, provided the required clearance is available. Galaxy does not level swim spas, so your concrete pad needs to be level before delivery.

How Do You Fill and Start Up Your Swim Spa?

Filling is done through the filter compartment, not directly into the spa, to prevent air locks in the jets and pumps. Use a prefilter if possible to reduce sediment going into the water.

Once filled, turn on the power at the breaker. Insert a mineral stick into the skimmer or filter area if you’re using one. Test and balance the water (pH 7.2 to 7.6, total alkalinity 80 to 120 ppm, calcium hardness 100 to 400 ppm). You can also bring a water sample to any Galaxy location for free testing.

Add your startup chemicals, typically a granular chlorine or bromine sanitizer plus an oxidizing shock. Keep the cover open and jets running for 30 minutes before getting in or closing the cover.

Before using the spa for the first time, rinse (don’t wash) your bathing suits and remove any lotions or makeup to keep the water clean and prevent foaming.

What Weekly Maintenance Does a Swim Spa Need?

Swim spa maintenance is much simpler than traditional pool maintenance thanks to smaller water volume and better covers.

Test your water weekly with test strips, or bring a sample to any Galaxy location for a free digital test. Keep pH between 7.2 and 7.6, total alkalinity 80 to 120 ppm, and calcium hardness 100 to 400 ppm. Always adjust alkalinity first, then pH.

Add a weekly dose of stain and scale inhibitor. Add sanitizer based on your system (chlorine, bromine, salt, ozone, or UV). With a mineral stick, free chlorine can stay as low as 1 ppm.

After each use, add an oxidizing shock with the cover off and jets on, and wait 15 minutes before closing the cover. Shock the spa weekly even if it hasn’t been heavily used.

Rinse your filters monthly and deep-clean them every 3 to 4 months with filter cleaner.

Galaxy offers free Hot Tub School monthly or you can walk into any showroom, 7 days a week.

What Longer-Term Maintenance Does a Swim Spa Need?

Always turn the pump off before changing the valve position, and only turn the multi-port valve clockwise. There’s a gasket inside that will tear if turned the other direction.

Beyond weekly care, swim spas need occasional deeper maintenance. Drain and refill every 3 to 4 months. This coincides with replacing your mineral stick and gives you a chance to purge the plumbing lines with a cleaner like Hot Tub Serum Total Cleanse, which removes biofilm from pipes and jets. Before draining, add the purge product and run the jets so it can work through the full system.
Clean the shell, cabinet, and underside of the cover with a surface cleaner. A microfiber cloth or magic eraser handles most buildup. Condition vinyl covers with cover conditioner every 3 to 6 weeks. In direct sun 8+ hours a day, do it monthly.

Annually, replace UV bulbs (every year on Jacuzzi and Sundance, every 2 to 3 years on Nordic and CalSpas) and clean the quartz tube. Inspect filters and replace if needed. Remove diverter valves and jets occasionally and soak them in a cleaner for extended life.

Swim spas don’t need to be winterized. Keep them running year-round at a consistent temperature. The insulation is designed for continuous operation, and shutting down actually causes more wear than running consistently.mai
Backwash position churns the sand and runs water backward through the filter to flush trapped debris. Use this when the pressure gauge reads 7 to 10 psi above your normal running pressure. Backwash for about 1 to 2 minutes, then switch to Rinse for half that time. Rinsing compacts the sand so it doesn’t blow back into the pool through the return jet.
Waste/Drain position is for lowering the water level or vacuuming algae and heavy debris. Keep a garden hose running in the pool when vacuuming on waste, and never let the water drop below the skimmer.
Recirculate/Whirlpool position circulates water without passing through the sand. This is rarely used and only recommended if we specifically advise it.
Closed/Test position is used when checking the pump basket, cleaning the filter, or replacing components.
Winterize position is used when closing the pool for the season.

The first time you start the system, begin on backwash for 1 to 2 minutes, switch to rinse for 30 seconds, then move to filter. This clears sand from the lines and prevents it from entering the pool.

What Sanitization Systems Are Available Through Galaxy?

A few system options we carry and recommend for swim spa and hot tub owners.

Mineral sticks use silver and copper to sanitize the water and prevent algae, letting you cut chlorine or bromine use to about 1 ppm. Replace every 4 months when you drain and refill.

FROG @ease is a sanitizing system designed for Jacuzzi and Sundance models that uses SmartChlor technology paired with mineral cartridges. It self-regulates chlorine on demand and maintains 0.5 to 1.0 ppm automatically. Replace the mineral cartridge every 4 months and the SmartChlor cartridge when the test strip shows it’s depleted.

Floating automatic sanitizer systems house chlorine or bromine in a floating device that slowly dispenses sanitizer into the water. Low-maintenance and widely compatible.

Chemical feeders dispense and regulate chemicals automatically, offering both manual and automatic options. CalSpas, Hydropool, and Jacuzzi all offer chemical feeder options on compatible models.

How Do You Troubleshoot Cloudy or Foaming Water?

Most water issues come from water that’s out of balance, which prevents your shock and sanitizer from doing their jobs.

For cloudy water, test and adjust pH and total alkalinity first. Then add shock and run the jets with the cover off for 30 minutes. If cloudiness persists, add a water clarifier to help the filter catch fine particles.

Foaming usually isn’t a water balance issue. Common causes are bathing suits washed in detergent (rinse them instead), bathing suits used at lakes or beaches (keep a separate pair for the spa), lotions and makeup, and non-spa fragrances.

For immediate relief from foam, use a spa defoamer. It’s a temporary fix. For lasting results, rinse filters with filter cleaner, or drain, clean, and refill if the buildup is heavy. Replace the mineral stick when you refill.

Bring a water sample to any Galaxy location for free digital testing if you can’t figure out what’s going on. Most water issues are solvable in one visit.

How Do You Open Your Pool for the Season?

Open your pool when the water temperature reaches about 60 degrees.

Start by cleaning all water and debris from the cover, then remove it. Fold the cover and soak it in a garbage pail with pool cover cleaner, let it dry, and store it.

Hook up your hoses and replace any plugs on the filter, pump, and motor. Make sure all o-rings and gaskets are in place. Remove any winter plugs from the return jet and skimmer, then fill with fresh water until it reaches the middle of the skimmer.

For sand filters, start on backwash for 2 minutes, rinse for 15 to 30 seconds, then switch to filter. For cartridge filters, place a clean filter in the canister and replace the winter drain plug.

Vacuum and clean the pool, then let the pump run for 24 hours. After that, bring a water sample to any Galaxy showroom and we’ll test it and help you get the chemicals you need to balance your water for the season.

What Smart Features and Controls Are Available?

Modern swim spas include a range of convenience and control features.

Touchscreen displays let you control temperature, jets, and lighting from the spa side. They’re waterproof and durable, and give you a cleaner interface than mechanical controls.

Mobile apps let you adjust temperature, jet intensity, and lighting from your phone or tablet. Many include maintenance reminders and troubleshooting support.

SmartTub is Jacuzzi’s app platform, with automated usage schedules, voice assistant integration (Alexa, Google), wearable support, and integration with the FROG @ease water care system for simplified maintenance.

Entertainment options include LED lighting, waterfalls, cup holders, and stereo systems. Evening appearance matters too. LED lighting turns the spa into a focal point of the backyard when it’s not in use.

What Accessories Should You Consider?

The right accessories make daily use easier and protect your investment.

Covers are essential for keeping debris out, holding in heat, and protecting water quality. Match the cover size and density to your spa and climate.

Cover lifters make daily use much easier. Galaxy offers several options: the G-Lyft (basic, needs 15 to 18 inches of clearance behind), hydraulic lifts (needs 6 inches behind), cover shelves (needs 32 inches), and Cover RX (needs 18 inches behind, no side clearance).

Steps give you safe entry and exit and are worth having even if your spa is sunk into a deck. Spa trays, aftermarket headrests, and towel bars round out comfort.

For fitness, there are workout-specific accessories including boogie boards, boxing-inspired Box Fit gloves, cable resistance bands, rowing kits, and SMART goggles that track strokes, heart rate, and performance via Bluetooth.

What Are the Operating Costs of a Swim Spa?

Operating costs are lower than most people expect, especially for well-insulated models.

Monthly electricity typically runs $50 to $100, depending on climate, usage, model, and insulation quality. Energy-efficient models with full foam insulation sit at the lower end. The initial heat-up to bring the spa to temperature costs $500 to $800, but after that, maintaining temperature is the main ongoing cost.

Water costs come from the 2 to 3 drain-and-refills per year. This adds up over time but isn’t a major expense in most areas.

Chemical costs run $350 to $1,000 annually, depending on your sanitization system. Mineral-based and UV-based systems tend to be on the lower end because they reduce chlorine or bromine consumption.

Factor in filter replacements (most owners replace filters annually) and occasional mineral stick or cartridge replacements.
