Saltwater hot tub cost factors
Several factors contribute to the overall cost of installing a saltwater hot tub, including:
Above-ground vs. inground: Inground hot tubs cost more than above-ground models due to the extra electrical work and construction costs. However, above-ground models often require pouring a concrete pad for support before installing.
Material: Hot tub prices vary by material. Acrylic is durable and attractive. Rotomolded and vinyl tubs are budget-friendly and lightweight. Fiberglass balances strength and efficiency, while wood exterior provides a rustic look. Stainless steel is the most durable and modern-looking material but the most expensive.
Brand: Different hot tub brands offer varying price points and features. For example, Lifesmart models cost less than high-end brands like Bullfrog and Hot Spring Spas.
Add-ons: High-end features like advanced jet systems, LED lighting, and smart controls can increase the overall cost. Adding a pool deck costs $25 to $50 per square foot on average for the materials and labor.
Energy costs: Hot tubs consume a significant amount of electricity to heat the water and run the pumps. The cost to run a hot tub ranges from $20 to $60 per month, depending on the water temperature and how often you use it.
Climate: In colder states, you may use more energy to maintain water temperature. In warmer areas, you might need to address issues like algae growth more often.
Maintenance
Hot tub maintenance costs $50 to $200, including professional labor fees and materials like filters. Saltwater hot tubs require similar maintenance to chorine hot tubs when it comes to cleaning and repairs, but some aspects are different.
Hot tub cleaning costs $50 to $100 and helps maintain its appearance and functionality.
Replacing the cell of a saltwater generator costs $100 to $500 every 3 to 6 years.
A hot tub repair costs $200 to $500 for most minor repairs, such as fixing a tiny crack or replacing a seal. Major repairs, like replacing the motherboard, may cost $1,500+.
Winterizing your hot tub during the colder months costs $200 to $500 and prevents damage from freezing water. This service includes draining the hot tub, blowing out the jet lines, and applying antifreeze. Reopening your hot tub in the spring costs $100 to $250.
Ask your hot tub installer if they offer a maintenance plan. You may be able to get a reduced rate by pre-paying for an annual maintenance contract.
Cost to convert hot tub to saltwater
Converting a regular chlorine hot tub into a saltwater hot tub costs $500 to $3,000. Most hot tubs can support a saltwater system, but not all can, so check with the manufacturer first.
The average hot tub costs less than a saltwater tub, so adding a saltwater system instead of purchasing a saltwater hot tub can save you money. Basic aboveground hot tubs start at $3,000, whereas saltwater hot tubs start at around $4,500.
FAQs about saltwater hot tubs
How does a saltwater hot tub work?
Saltwater hot tubs use a salt-chlorine generator to convert sodium chloride (salt) into chlorine through electrolysis. This can maintain clean water with fewer added chemicals, which means it's gentler on your skin while still sanitizing the water.
What are the negatives of a saltwater hot tub?
Saltwater may be gentler on skin than chlorine and other standard pool chemicals, but there are some downsides:
Saltwater systems are more expensive to install.
Saltwater can corrode metal components, leading to premature wear, extra cleaning of calcium residue, and repairs.
Regular cleaning of the salt cell is necessary and can be costly if you use professional services.
Adding salt affects the pH of the water, requiring adjustments to maintain optimal levels.
Some individuals experience skin dryness when using saltwater systems.
Can any hot tub use saltwater?
No, not all hot tubs can use a saltwater system. The hot tub must be equipped with special parts designed for saltwater sanitization. Saltwater may corrode internal metal components over time, so some manufacturers decline warranty coverage if you install an aftermarket salt system.
Are saltwater hot tubs worth it?
While initial costs are higher for saltwater hot tubs and the salt may corrode internal parts, many users find them worthwhile. Benefits include comfort for sensitive skin, eco-friendliness, less odor from chemicals, more buoyancy, and easier maintenance.
Getting estimates from hot tub companies
While searching for hot tub installers near you, be sure to:
Get at least three quotes from licensed and insured professionals for a thorough comparison.
Read reviews of their past work on platforms like HomeGuide and Google to gauge their reputation and quality of service.
Be cautious of selecting the company with the lowest estimate, as it may suggest subpar workmanship.
Request a written, itemized contract and warranty before any work begins.
Don't make substantial upfront payments. Instead, settle the final bill only upon completion of the service.
