Quick Answer: A hot tub costs $300 to $800 for a basic inflatable, $2,000 to $4,000 for a plug-and-play hard-shell spa, and $5,000 to $16,000+ for a hardwired hard-shell spa — before installation. Installation adds little to nothing for 120V models but $500 to $1,500+ for a licensed 240V electrician install on a hardwired spa. Once running, expect $30-$60 a month in electricity on top, regardless of which type you buy.

Hot tub shopping guides usually quote one number and move on, but the real answer splits into three very different price tiers depending on which type of spa you’re looking at — and the sticker price is rarely the whole story once electrical work enters the picture. This guide breaks down what each tier actually costs, what installation adds, and where the ongoing bills land once you’re soaking.
Hot tub prices by the numbers
- Inflatable spas average around $500, with budget models like the Coleman SaluSpa Miami starting near $350 and better-insulated winter models like the St. Moritz running closer to $790 — a roughly 10-to-30x gap versus a hard-shell spa’s unit price.
- A licensed 240V electrician install runs $500-$1,500+, per our hot tub wiring guide, driven mainly by how far the panel sits from the tub and whether a permit is required under NEC Article 680 — this is the cost hard-shell buyers most often forget to budget for.
- Running cost lands at $30-$60 a month for nearly every type, at the 18.8¢/kWh national average residential electricity rate (EIA, April 2026) — see our running cost guide for the full monthly breakdown by insulation and climate.
Inflatable hot tubs: $300-$800
Inflatable spas are the cheapest way into hot tub ownership by far. A Coleman/Bestway SaluSpa Miami starts around $350 for a basic 4-person round tub, while a heavier-duty winter-rated model like the SaluSpa St. Moritz — with FreezeShield protection and an EnergySense cover — runs closer to $790. The Intex PureSpa Plus sits in between at roughly $500-$600 and adds app control and a built-in hard-water system.
Installation cost for an inflatable is effectively $0 in most cases: it plugs into a standard 120V GFCI-protected outlet, the same class of circuit as a kitchen countertop appliance. The only real prerequisite is a flat, stable surface — a foam mat or paver base, both well under $100 — since these tubs have no rigid shell to distribute weight on an uneven patio. See our best inflatable hot tub roundup for current top picks by size and budget.
Plug-and-play hard-shell spas: $2,000-$4,000
Plug-and-play spas like the AquaRest AR-150 Select (roto-molded shell, full-foam insulation, molded seats) sit in the middle tier, typically $2,000-$4,000. They still run on a standard 120V outlet like an inflatable, so installation cost is usually $0 to ~$150-300 if a new dedicated circuit is needed — no electrician required in most jurisdictions, just a licensed check of the outlet.
Plug-and-Play Hard-Shell Spa
- Roto-molded thermoplastic shell and full-foam insulation last longer than an inflatable's PVC liner — typically 10+ years with normal care.
- Runs on the same 120V GFCI outlet as an inflatable, so there's no electrical upgrade cost in most homes.
- Molded seating and stronger jets close most of the comfort gap with a hardwired spa at a fraction of the price.
This tier is the sweet spot for buyers who want a real hard-shell spa without a 240V electrical project — see our best plug-and-play hot tub guide for current models.
Hardwired hard-shell spas: $5,000-$16,000+ (plus installation)
A permanent 240V hardwired spa — the category most people picture when they hear “hot tub” — runs $5,000-$16,000+ for the unit alone, scaling with seat count, jet count, and features like waterfalls or ozone systems. Models like the Lifesmart LS350DX or LS500 Plus sit toward the lower-middle of that range; see our best hot tub under $5,000 guide if that’s your ceiling.
The number most shoppers miss: installation is not optional here. NEC Article 680 requires a licensed electrician to run a dedicated 2-pole GFCI breaker — commonly 50A — and 6 AWG copper wire to an outdoor disconnect. That job runs $500-$1,500+ depending on how far the tub sits from your panel, per our full wiring guide. Budget for a permit fee on top in most municipalities, and factor in a reinforced pad if your patio isn’t already flat and load-rated for a full, water-filled spa’s weight.
| Type | Unit price | Installation | All-in cost |
|---|---|---|---|
| Inflatable | $300-$800 | $0 (existing outlet) | $300-$850 |
| Plug-and-play hard-shell | $2,000-$4,000 | $0-$300 | $2,000-$4,300 |
| Hardwired hard-shell | $5,000-$16,000+ | $500-$1,500+ | $5,500-$17,500+ |
Budgeting for the electrical work up front is worth doing before you fall for a specific model — start a free Amazon Prime trial and GFCI outlet covers, conduit fittings, or a replacement breaker can be on your doorstep the next day instead of adding a second trip to the hardware store mid-install.
What it costs to actually run one
The purchase price is only the start. Every tier — inflatable, plug-and-play, or hardwired — lands in roughly the same $30-$60 a month electricity range once it’s running, since a hard-shell spa’s better insulation mostly offsets the larger volume of water it heats. Add ongoing supplies: sanitizer, test strips, and filters typically run $20-$40 a month; see our hot tub chemicals guide for the breakdown. Our running cost guide covers the full monthly math by insulation level and climate, and our maintenance guide covers the routine that keeps the pump and heater from working — and costing — more than they should.
The bottom line
Expect $300-$800 for an inflatable, $2,000-$4,000 for a plug-and-play hard-shell spa, or $5,500-$17,500+ all-in for a hardwired hard-shell spa once electrical work is included — and roughly $50-$100 a month in electricity and chemicals on top no matter which you pick.
