Hot Tub Cost (2026): By Type, Seating & Running Cost
Updated October 2026
A hot tub costs $4,000–$8,500 installed, averaging about $6,900 (Fixr), with a low end near $1,000 (small inflatable) and a high end of $20,000 (large custom). The two levers are type — inflatable $500–$3,000, rotomolded $2,500–$6,000, acrylic $4,500–$9,000, swim spa $15,000–$40,000 — and seating, from 2–3 person ($1,800–$10,500) to 8+ ($6,800–$20,000). Then come the recurring costs: $20–$50/month electricity and $50–$300/month maintenance service.
Cost by tub type
| Type (per tub, installed) | Fixr installed cost | What it is |
|---|---|---|
| Inflatable | $500–$3,000 | Budget, portable, 110V plug-and-play; shortest lifespan. |
| Rotomolded (polyurethane) | $2,500–$6,000 | Durable budget shell; MasterSpas puts budget tubs at $4,000–$8,000. |
| Acrylic | $4,500–$9,000 | The mainstream dealer spa — best insulation and hydrotherapy. |
| Swim spa combo | $15,000–$40,000 | Exercise + spa in one; the premium end of the category. |

The add-ons and line items
- Delivery & transport: $250–$400 — +$200 if a crane is needed — Fixr, single source (flagged).
- 220V electrical hookup: $120–$700 (typical $435) — Fixr; inflatables on a standard 110V outlet skip this.
- Building permit: $50–$300 — Fixr, single source (flagged).
- Cover: $75–$400 — Fixr add-on table (single source, flagged).
- Cover lifter: $150–$400 — Fixr add-on table (single source, flagged).
The running costs people forget
The purchase is the one-time number; the ownership cost is monthly. Electricity runs $20–$50/month in a temperate climate (Fixr; MasterSpas similar — colder climates run more), and professional maintenance service runs $50–$300/month (labor + chemicals). The commonly quoted “$600–$3,600/year in chemicals” figure is that service band annualized — no cited source publishes a chemicals-only annual figure, so we keep the basis stated rather than inventing one. Site prep and a level pad or foundation are convention-level requirements (verify with your dealer); no cited per-job figure exists.
Outdoor living, priced like everything else
A hot tub is an outdoor-living upgrade, not a spa-day expense — same logic as our pool cost guides and pool deck resurfacing cost breakdown: know the installed band, then the recurring line items. If the project list is getting long, the landscaping cost guides cover the yard work that usually comes with it.
FAQs
How much does a hot tub cost installed?
Fixr puts a prefab hot tub installation at $4,000–$8,500 with an average around $6,900, in a full range of $1,000–$20,000. MasterSpas frames the shopper range at $4,000–$25,000+, with most buyers at $10,000–$17,000 — the spread is seating, shell quality, and how much of the site prep you pay for.
What is the cheapest hot tub that actually lasts?
Inflatable tubs run $500–$3,000 but have the shortest lifespan. Rotomolded polyurethane tubs ($2,500–$6,000 per Fixr) are the durable budget tier; acrylic ($4,500–$9,000) is the mainstream long-life choice.
What does a hot tub cost per month to run?
Electricity runs $20–$50/month in a temperate climate (Fixr; MasterSpas similar), and professional maintenance service runs $50–$300/month — that service band, annualized to $600–$3,600, includes labor plus chemicals, not chemicals alone.
