Hot Tub Cost: By Type, Size & Tier (3 References)

A hot tub costs $3,000 to $10,000 for an above-ground model, with national averages of $6,000 to $6,900 installed.¹²³ Inflatable spas start at $400; in-ground builds run $8,000 to $25,000 (Angi, HomeGuide).¹² Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on size, shell material, features, delivery, site prep, wiring, and permits ($200 to $2,200 of site extras, Angi).¹

Quick math: the two averages land $900 apart ($6,000 Angi, $6,900 Fixr) and both describe a mid-tier 4-to-6-person install, our reading.¹³ Note that Angi and HomeGuide publish identical material and in-ground tables — shared data, so those rows count as one source, our note.¹²

Cost by type

Type	Cost	Source
Inflatable	$400 – $1,500	Angi / HomeGuide
Rotomolded plastic	$2,000 – $6,000	Angi / HomeGuide
Wooden	$3,000 – $10,000	Angi / HomeGuide
Vinyl-lined	$4,000 – $12,000	Angi / HomeGuide
Acrylic / fiberglass	$4,000 – $18,000	Angi / HomeGuide
Salt water	$6,500 – $18,000	HomeGuide
In-ground	$8,000 – $25,000	Angi / HomeGuide

Acrylic is the most common above-ground shell and the priciest, lasting 5 to 20 years (HomeGuide).² Adding an in-ground spa during a pool build costs less, $6,000 to $15,000, because excavation and equipment are shared (Angi, HomeGuide).¹²

Cost by quality tier (HomeGuide)

Tier	Price	What you get
Entry-level	$2,000 – $6,000	Basic jets, plug-and-play 120V, lighter build
Value	$4,000 – $8,000	Acrylic shell, more jets, better insulation — the common choice
Premium	$8,000 – $11,000	Stronger pump and jets, energy efficiency, longer warranty
Luxury	$11,000 – $18,000	Top jet count, salt-water option, 20+ year lifespan

The value tier is where most buyers land, our reading of HomeGuide’s “most common” label.²

Cost by size (Angi)

Capacity	Price
2–3 people	$2,000 – $7,000
4–5 people	$2,000 – $12,000
6–7 people	$3,000 – $15,000
10 people	$5,000 – $20,000+

Installation and extras

Item	Cost	Source
Installation labor	$650 – $6,100	Angi
Site prep, wiring, permits, delivery	$200 – $2,200	Angi
Prefab install (total)	$4,000 – $8,500	Fixr
Custom build (total)	$5,000 – $20,000	Fixr
Indoor install premium	$5,000 – $25,000 (vs $4,000 – $20,000 outdoor)	Fixr

Indoor installs cost more because of ventilation and drainage requirements (Fixr).³ Most above-ground tubs need a 240V circuit — see our electrician cost guide for wiring rates, our pointer.

Worked examples

Example 1 — inflatable for two. $400 to $1,500 for the tub; Fixr’s $1,000 low-end job includes setup.¹³

Example 2 — value acrylic, 4–5 people, outdoor pad. $4,000 to $8,000 tub (HomeGuide) + $650 to $2,000 light labor and wiring, our arithmetic; matches Fixr’s $6,900 average mid-band.¹²³

Example 3 — in-ground spa with new pool. $6,000 to $15,000 bundled (Angi, HomeGuide) versus $8,000 to $25,000 standalone, a $2,000 to $10,000 saving, our arithmetic.¹²

FAQ

Cheapest real hot tub? Rotomolded plastic at $2,000 to $6,000 — durable, plug-and-play, a step up from inflatable (Angi, HomeGuide).¹²

Is a salt-water tub worth it? $6,500 to $18,000 (HomeGuide): gentler water and less chemical handling, but a higher entry price, our judgment.²

What does installation add? $650 to $6,100 (Angi) — a simple pad-and-wire job sits at the bottom; excavation for in-ground pushes the top.¹

Indoor or outdoor? Outdoor is cheaper ($4,000 to $20,000 vs $5,000 to $25,000, Fixr) because ventilation and drainage come free outside.³

Prefab or custom? Prefab ($4,000 to $8,500) for most buyers; custom ($5,000 to $20,000) for built-in looks and unusual spaces (Fixr).³
