A saltwater hot tub averages $20,250, but it ranges from $16,500 to $24,000 depending on the size and whether you choose an aboveground or in-ground model.
For most homeowners, a saltwater hot tub costs between $5,500 and $24,000. You could spend up to $35,000 if you build a custom, in-ground hot tub with high-end features and materials. The good news is that budgeting is possible. The average saltwater tub costs about $20,250, and small plug-and-play models can cost even less.
Saltwater hot tubs cost more than your average chlorinated hot tub because they use a saltwater generator and have corrosion-resistant equipment. Nonetheless, the price is all about the model you choose and the work you’ll need to accomplish. This guide can help you plan a budget.
Homeowners love saltwater hot tubs because they’re easier to maintain and a bit gentler on the skin compared to traditional hot tubs. Like all types of pools, there are a bunch of different factors that impact the total cost.
Prefab hot tubs can cost less than custom hot tubs, depending on the model. There isn’t a wide range of saltwater hot tubs on the market. For example, you can’t purchase a saltwater Jacuzzi, but brands like Hot Spring and Caldera offer ready-to-use prefab options. Most prefab saltwater tubs cost between $9,000 and $20,000.
If you install a custom saltwater hot tub, you can expect to spend $5,000 to $20,000 on the tub (including labor) and an extra $500 to $2,500 for the saltwater generator. The total cost can reach $35,000 if you choose luxury materials and high-end features. There’s far more room for the price to grow.
Larger hot tubs cost more, especially if they’re custom. That said, it depends on the brand and the model. In general, you can expect saltwater tubs—whether you go prefab or custom—to fall into the following range based on size.
| Hot Tub Size | Price Range (Tub Only) |
|---|---|
| Small (2–3 people) | $5,500–$15,500 |
| Medium (4–5 people) | $9,500–$22,500 |
| Large (6–7 people) | $10,500–$24,500 |
| Extra Large (8+ people) | $18,000–$35,000 |
Since there aren’t a lot of prefabricated saltwater hot tubs on the market, you don’t have a large range of materials to choose from. The material makes more of a difference when you build a custom saltwater hot tub or heated saltwater plunge pool.
Generally, the most affordable are vinyl liners (standard for in-ground tubs) or rotomolded plastic (common for aboveground tubs). Vinyl-lined tubs and acrylic or fiberglass tubs tend to cost more.
Typically, in-ground hot tubs cost more than an aboveground hot tub. This is because of the labor involved. The most budget-friendly type of hot tub is an aboveground, plug-and-play model. These models are 120 instead of 240 volts and generally don’t require additional plumbing or electrical work. You can just plug them into a regular GFCI outlet, but finding one compatible with a saltwater system may be a struggle.
| Aboveground Hot Tub | In-Ground Hot Tub |
|---|---|
| Very few saltwater models | Any design, size, and shape |
| Lasts 5–20 years | Lasts 10–50 years |
| 6–8 hour installation | 2–6 week installation |
| More affordable | Can be cost-prohibitive |
| Easier to maintain | Can be difficult to repair |
A high-end saltwater hot tub with luxury features can cost twice as much as a basic model of the same size. Though all saltwater hot tubs are considered luxury products, even name brands tend to have different product lines at different price points. Choose from the line that best suits your budget.
When you install a hot tub, there’s often some site prep involved. Aboveground models need a concrete slab or pavers for support. Your contractor may need to level the ground or excavate. If you install your hot tub indoors, you may need to reinforce the flooring. Here are some typical costs.
| Site Prep Job | Cost |
|---|---|
| Excavation | $400–$1,500 |
| Land leveling | $1–$2 per sq. ft. |
| Patio paver installation | $8–$15 per sq. ft. |
| Concrete slab installation | $4–$8 per sq. ft. |
| Floor reinforcement (indoors only) | $40–$60 per sq. ft. |
For most homeowners, hot tub wiring costs $1,900 to $4,200. If you have a 240-volt hot tub or your plug-and-play model keeps tripping the breaker, you’ll need some electrical work to get it up and running. This could include upgrading your subpanel or installing a new GFCI outlet, GFCI breaker, or subpanel.
Generally, new plumbing pipes cost $350 to $2,000. Most prefab hot tubs don’t need additional plumbing, but you may need plumbing work if you’re building a custom hot tub or an in-ground model. Even if you already have a pool, your hot tub needs its own heating system.
Most people spend $650 to $6,100 on labor to install a hot tub. In-ground hot tubs come with the highest labor costs, but even aboveground hot tubs usually require electrical work and land prep. Some hot tub installers may charge a flat fee. Here are some typical rates for hot tub contractors:
Hot tub installer: $50–$100 per hour
Pool electrician: $50–$200 per hour
Plumber: $45–$200 per hour
Landscaper: $50 to $100 per hour
If you’re installing an in-ground hot tub or your hot tub requires electrical work, you’ll probably need a permit. This adds $100 to $250 to your total bill.
Delivery is sometimes included in the total cost of a hot tub. If not, expect to spend $200 to $500. If the installation area is inaccessible and your hot tub must be delivered by crane, delivery can cost $800 or more.
To convert a regular hot tub into a saltwater hot tub, you’ll need to install a salt hot tub system. A saltwater generator typically costs $200 to $700, though it could cost as much as $2,500. Most—but not all—hot tubs can support a saltwater system, so make sure you check with the manufacturer.
The average hot tub costs considerably less than a saltwater tub, so adding a saltwater system can save you money vs. purchasing a saltwater tub outright. Basic aboveground hot tubs start at $2,000, whereas saltwater hot tubs start at around $6,500.
Compared to other home upgrades, pools and hot tubs are high maintenance. Saltwater tubs are easier to care for, but you should still budget for the ongoing costs. Things like repairs and supplies can significantly add to your annual household budget.
| On-going Expense | Cost |
|---|---|
| Electricity | $240–$600 per year |
| Chemicals and Testing | $50–$100 per year |
| Salt and Cartridges | $200–$450 per year |
| Maintenance | $240–$900 per year |
| Repairs | $175–$1,000+ per repair |
| Water | $1–$50 per fill |
Hot tubs add around $20 to $50 per month to your electric bill, so plan to add $240 to $600 per year to your household budget. High-efficiency models and a high-quality pool cover can reduce these costs. If you use your hot tub frequently, running the heater continuously at a temperature of 80 to 95 degrees Fahrenheit is also a good idea. This can help conserve energy.
Certain chemicals help you sanitize your tub and raise or lower the pH of the water. Salt does the heavy lifting, so you won’t need to add chlorine. You’ll still need to purchase pH and alkalinity treatments and non-chlorine shock. You also need to buy test strips and regularly test your water.
Instead of chlorine, your pool will need salt. Saltwater hot tubs use saltwater cartridges, which cost $50 to $130 each. The salt itself costs $10 to $40 for a 10-pound bag. You’ll generally need to change the cartridge every four months, but it depends on the hot tub saltwater system.
Hot tub maintenance costs $240 to $900 per year for most homeowners. You’ll need to clean and replace filters regularly and clean certain saltwater components. A professional cleaning costs around $100 to $300, but many hot tub owners do the job independently for significantly less. Cleaning solutions only cost about $15, and filters cost $20 to $60.
Most hot tub repairs cost $175 to $550, but certain repairs can cost more than $1,000. Repairs are bound to pop up if you’ve had your hot tub a long time. These aren’t an everyday (or even seasonal) occurrence, but you should still save money for emergency repairs.
The cost of water depends on the source and the volume of your tub. Most people spend between $1 and $50 to fill their hot tub. Using municipal water straight from the garden hose is usually the most affordable.
Installing a saltwater hot tub is a challenging DIY. Even the simplest models typically require electrical installation. This can be extremely hazardous, especially since some components come into direct contact with water. You likely wouldn’t even be able to get a permit unless you’re working with a licensed contractor.
The best route is to hire a hot tub installer near you. Saltwater hot tubs are a niche luxury product. There aren’t many prefab models on the market, and custom work can be difficult and time-consuming. A pro will know your options—and how to install them right.
You may also want to purchase some accessories or do additional work when you install your hot tub. Common add-ons include everything from pool deck installation to lighting and landscaping.
If you plan to install new pool lights, expect to spend $450 to $900 per light. Some high-end LED or fiber optic lights could cost more than $1,500. Lighting is essential if you want to use your hot tub after dark.
If you want to install a pool deck around your aboveground hot tub, budget between $4,100 and $11,300. The cost of a deck is highly dependent on the material, but this is a major project that can transform the look of your hot tub area.
Landscaping costs between $1,300 and $6,050, but you could spend less on a smaller landscaping project, like throwing some grass seed over the area where your hot tub wiring was buried. Some typical costs include:
Sod: $0.35 to $0.85 per sq. ft.
Gravel: $40–$100 per cubic yard
Patio: $1–$35 per sq. ft.
Fencing: $11–$90 per lin. ft.
Hot tub accessories include covers, thermal blankets, Bluetooth speakers, and floating serving trays. A well-insulated cover is essential if you want to reduce energy costs. Common accessories include:
Hot tub cover: $50–$650
Thermal blanket: $55–$550
Thermometer: $10–$15
Floating cup holders: $5–$25
Bluetooth speakers: $40–$125
A ventilation fan typically costs $200 to $600. This add-on is essential for indoor hot tubs since it protects your interior from excess humidity. You’ll need ventilation to fight moisture and mold.
Want to reap the benefits of a hot tub on a budget? Here are some tips to help you save on installation:
Convert an existing hot tub to saltwater: You can save thousands of dollars by converting a regular hot tub into a saltwater model. Only some models are compatible, but there are certainly plenty of options.
Build a hot tub with your in-ground pool: If you’re planning to build a pool and think you may want a hot tub, do the work all at once. You can save $2,000 to $10,000 if you do the job simultaneously.
Negotiate the price: Don’t be afraid to negotiate with your hot tub dealer. Often, dealers markup the cost by up to 50%, so there’s some wiggle room.
Choose a smaller model: Larger hot tubs cost more to buy and install, so choose a model that fits two to three people unless you absolutely need something bigger.
Choose a basic model: Forgo luxury features and get a basic hot tub. Avoid luxury lines, if possible. Basic is usually the most affordable.
Try to get a used or refurbished hot tub: Saltwater hot tubs are a niche product, so you may be unable to find many used ones on the market. That said, you can save money by purchasing a used model to convert into a saltwater tub. This may take some serious searching, though.
Skip extra features: Pass on added LED lighting, speakers, and any unnecessary extras.
Look for tax deductions: If you need a hot tub for medical reasons, you may qualify for a tax deduction.
Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.
Saltwater hot tubs can cost twice as much as traditional hot tubs. The average hot tub costs $6,000, while the average saltwater hot tub costs $12,750. If you want to convert an existing hot tub into a saltwater hot tub, expect to spend an additional $200 to $2,500 on a saltwater system plus your contractor’s rate for labor.
