Average Cost of Hot Tub

A hot tub costs $3,000 to $10,000 on average, not including delivery or installation. Hot tub prices depend on the material, quality, features, add-ons, number of jets, brand, dealer's overhead, and warranty.

Hot Tub Electrical Installation Cost

Hot tub electrical installation costs $800 to $1,600 for a dedicated circuit to the electrical panel, underground conduit and wiring up to 100', and to install a 220V GFCI outlet or subpanel near the spa. Homes with existing wiring or outlet for a replacement spa costs $150 to $500 to hook up.

Older homes with 100 or 150-amp services or installing large hot tubs may require a total service capacity and panel upgrade to a 200 or 300-amp to handle the added capacity. The average cost to upgrade electrical panel for a hot tub is $1,200 to $3,000, depending on the size required.

Hot Tub Electrical Installation Cost - Chart

Hot Tub Electrical Installation Cost
Method Average Cost
Connect To Existing Wiring $150 – $500
Install Circuit, Wiring, Outlet/Subpanel $800 – $1,600
Upgrade Electrical Panel Service Capacity $1,200 – $3,000

*Most spa panels require a 50 or 60-amp, 220V or 240V with a dedicated GFCI power supply or a 15-amp, 120-volt plug-and-play with GFCI.

The spa should be placed in the desired location before the electrical installation. The spa panel requires installing no less than 5 feet away from the hot tub and 10 feet away from non-GFCI protected outlets to prevent electrocution risks.

Trenching and installing conduit underground is cheapest when performed by a landscaper instead of an electrician before the concrete pad is installed or the hot tub is placed.

Find electricians near you to hook up your hot tub.

Hot Tub Concrete Pad Cost

A concrete slab costs $5 to $10 per square foot or between $500 and $2,500 for a hot tub. Other options for a hot tub foundation pad are an existing patio, gravel base, pavers, reinforced deck, or plastic spa pad.

Hot Tub Base Pad Cost - Gravel, Concrete, Deck - Chart

Type Cost Per Square Foot
Gravel Base Cost $1 – $3
Plastic Foundation Pad $4 – $7
Concrete Slab Cost $5 – $10

Hot Tub Delivery Requirements

  • Shipping & Drop-Off – Most hot tub dealers deliver the hot tub to the backyard or installation location. Some retailers only deliver curbside on a pallet and require hiring movers.
  • Moving Crew – Moving a hot tub requires two to six people depending on the size, equipment used, and distance moved from the curb.

The cost to add a hot tub to an existing pool is $12,000 to $25,000, depending on the size and if it's level with the pool beam or raised. When building a hot tub, the existing pool needs resurfacing to seal the structure. Pool resurfacing costs $6 to $10 per square foot.

Adding a hot tub to a new inground pool costs $6,000 to $15,000 if built at the same time.

Below Ground Hot Tub Cost Factors

  • Location – The area needs enough space for excavation equipment, the pad, cover lifter, and walkway. Budget for repairing damage to existing landscaping from using heavy equipment. Costs increase if the ground is rocky or on a hill. The minimum excavation depth is 46” from the surface.
  • Electric & Plumbing – A 50-amp dedicated electrical panel with a GFCI circuit breaker is installed within 100 feet of the hot tub. A spa panel with emergency shutoff is installed within five feet of the tub. Plumbing includes fittings for the jets and lines for water flow. The pump is either housed with the hot tub or separately.
  • Material – Below ground hot tubs are either poured concrete, gunite, or a pre-fabricated acrylic or fiberglass shell.
    • Concrete is sprayed over rebar at high pressure around jet holes. A plaster or a natural stone blend is used as the finish.
    • Some shells require a poured and leveled concrete pad. Other shells have a support frame that requires a 10” gravel bed for drainage and a backfill mix of dirt, gravel, sand, or road base filled around the shell.
  • Size – The size of the hot tub is one of the main factors that affect the cost. Standard in-ground hot tub sizes are:
    • Small: 5’x5’ for 2 to 4 people
    • Medium: 6’x7’ for 5 to 6 people
    • Large: 9’x8’ for 7+ people
  • Waterline Tile, Coping, and Surround – Waterline tile costs $600 to $800. The coping between the hot tub and deck costs $10 to $50 per linear foot for tile or natural stone. Add a concrete, natural stone, or brick surround for $5 to $40 per square foot.
  • Features – Adding custom upgrades like waterfalls, entertainment systems, lighting, JetPaks, and covers add $500 to $10,000 to the total cost.

Cover Lock $15 – $130
Non-Slip Stairs $60 – $400
Privacy Screen $150 – $600
Drink Holders $25 – $200
Thermometer $10 – $50

Hot Tub Salt Water System Cost

A hot tub saltwater chlorine generator system costs $500 to $1,700 on average, depending on the manufacturer and type of hot tub. Saltwater systems convert dissolved salt into chlorine automatically, which lowers maintenance. Salt costs less than chlorine or bromine and removes the need to use chemicals.

Hot Tub Salt Water System Cost
Hot Tub Type Average Cost
Above-Ground $500
Built-In $1,700
  • Saltwater is softer and kinder to clothes and skin.
  • Using salt extends the time between drainings to up to 12 months, but the initial costs are high.
  • Some hot tub manufacturers decline warranty coverage when installing an aftermarket salt system.
  • Salt causes corrosion of internal metal components, resulting in repairs, poor performance, and a shorter lifespan.
  • Salt water can stain decks and damage surrounding plants and shrubs if it's not washed down after use.

Other Cost Considerations

Additional cost factors when installing a backyard hot tub include:

  • Steps – Installing weatherproof stairs cost $60 to $400 to allow easy access into and out of the hot tub.
  • Deck – The average cost to build a deck for a hot tub is $4,000 to $10,000 or between $15 and $30 per square foot.
  • Gazebo – Installing a gazebo costs $3,500 to $10,000 to add privacy.
  • Screen – Installing a basic privacy screen costs $150 to $600. A screened-in porch costs $600 to $3,500 to install.
  • LandscapeLandscaping around a hot tub costs $50 to $100 per hour Repair your landscape and complement your new outdoor hot tub for $500 to $750.
  • Fencing – Some cities' building codes require a set distance between the hot tub and the property line and a fence or safety barrier. Fence installation costs $13 to $25 per linear foot, depending on the type.
  • Independent Heater – An independent heater for a hot tub costs $150 to $1,500, depending on the size and wattage. These heaters help heat the water quicker and raise temperatures about 5 degrees per hour.
  • Tax Rebate – Those with a medical condition qualify for a tax deduction, reducing the cost of ownership by 25% to 40%.

DIY vs. Hiring A Hot Tub Installer

A DIY spa installation is complicated and may void the warranty. Installing a hot tub, spa, or jacuzzi requires electrical wiring and needs to follow local building codes to ensure safety. A professional installation eliminates any chance of electrocution, potential fire hazards, or plumbing leaks.

Before hiring a contractor, be sure to:

  • Get at least three estimates to compare.
  • Read reviews and check out their previous work on HomeGuide, Google, and the Better Business Bureau (BBB).
  • Select companies that are insured, bonded, and have been in business for longer than five years.
  • Avoid selecting the lowest quote as quality may suffer.
  • Ask for an itemized contract and warranty in writing.
  • Avoid making large payments upfront. Come up with a payment schedule for the work completed.

Questions To Ask Installers

  1. Can I see a portfolio of your past installation jobs?
  2. Are you licensed, insured, and bonded?
  3. How do you handle damages that happen on the job?
  4. Who's the project manager, and will you use subcontractors?
  5. What hours do you and your crew work?
  6. What permits do I need, and will you obtain them?
  7. What does your warranty policy include?
  8. What’s your payment schedule?
  9. Will you remove or dispose of my old hot tub?
