Shell type
Prefab acrylic shells run $6,000 to $17,000 installed. Custom gunite or shotcrete shells run $8,000 to $25,000 plus and unlock any shape, depth, or spillway design.
4 Factors That Affect In-Ground Spa Cost and How to Budget
In-ground spa cost in Long Beach runs $15,000 to $25,000 for a standard gunite build, with prefab inset shells starting near $10,000 and luxury custom spas reaching $40,000 or more. The gap is real. Shell type, heater, jet count, automation, finish, and yard access all move the number. This guide walks Long Beach homeowners through where every dollar goes so the quote on your kitchen table is no surprise.
An in-ground spa is sometimes called a built-in hot tub. Adams uses "spa" throughout this guide because that is the trade term and the build category we work in. We do not service portable or above-ground hot tubs.
How much does an in-ground spa cost in Long Beach?
A typical Long Beach in-ground spa costs $15,000 to $25,000 installed for a standard gunite shell with mid-range equipment, plaster finish, and basic automation. Prefab inset shells start near $10,000. Luxury custom spas with raised spillways, premium finishes, and full Pentair or Jandy automation reach $40,000 or more.
Pricing is fair and transparent for the quality of service you should expect on a build this size. The wide range is not marketing smoke. It tracks shell type, heater fuel, jet count, finish, automation, and how complicated the yard access is.
What drives the price of an in-ground spa
Six cost drivers shape every quote. Read this section before any builder visit so you know what they are pricing.
Heater fuel
Gas heaters cost $1,500 to $3,500 plus the gas line. Heat pumps cost $4,000 to $7,000 and run cheaper monthly. Electric resistance is the cheapest install but the most expensive run.
Jet count and pump
Six jets share one pump. Twelve to twenty therapy jets need a second pump rated for the spa. Each pump line adds $700 to $1,400 to the build.
Automation
Pentair IntelliCenter or Jandy AquaLink phone control adds $1,500 to $4,000. Worth it on combos and spas with multiple zones. Skip on a stand-alone budget build.
Finish and tile
Standard plaster is the budget pick. NPT pebble or quartz finish adds $2,500 to $6,000. Glass or premium ceramic waterline tile adds another $1,500 to $4,000.
Yard access and plumbing run
A clear side yard with thirty feet of plumbing run is the cheap case. Tight access, mature landscaping, or a long pad-to-spa run can add $1,500 to $5,000 in trenching and crane time.
A pool plus spa combo build saves $2,000 to $10,000 on shared excavation, plumbing, and electrical. We see this work best on new pool projects in Belmont Shore and Naples Island. See the pool spa combo design page for combo design notes.
Cost ranges by tier, budget mid-range and premium
Budget tier, $10,000 to $15,000
Prefab acrylic inset shell. Gas heater or electric resistance. Six jets on one pump. Standard plaster pad and basic concrete coping. No automation. Best for renters-turned-buyers and homeowners who want hot water this season without a full custom build.
Pricing
Quoted on inspection
Mid-range tier, $15,000 to $25,000
Custom gunite shell. Pentair or Jandy heater rated for the spa size. Eight to twelve jets, two pump lines. NPT plaster or quartz finish, waterline tile band, integrated coping. Optional Jandy AquaLink automation. This is the most common Long Beach build and the band where Adams sits about 20 percent under the local market for the same scope.
Pricing
Quoted on inspection
Premium tier, $25,000 to $40,000 and up
Raised spa with one or two spillways feeding a pool or deck channel. Twelve to twenty therapy jets across two or three pumps. Pentair IntelliCenter or Jandy iAquaLink full automation. NPT pebble finish, glass tile, LED lighting, optional cold plunge attachment. Six to eight week build window once permits clear.
We publish these bands on the in-ground spa installation page too, sized to standalone, pool combo, and luxury scope.

What's included in in-ground spa installation
A turn-key Long Beach in-ground spa install covers six steps end to end. Anything outside this list is a separate line item, not a hidden surprise.
Design and permit
We map the spa to your yard, draw the plan, and file with Long Beach Planning. Plan check runs two to four weeks.
Excavation and steel
Crew digs the footprint, hauls spoil, and ties the rebar cage. Plumbing stubs go in before steel inspection.
Plumbing and electrical rough-in
A separate 240V GFCI circuit lands at the pad. Gas or heat pump line runs to the heater bay.
Gunite shell pour
Pneumatic gunite forms walls and floor. Two-week cure before finish work begins.
Tile, coping, plaster
Waterline tile sets, coping lays, and the NPT plaster or pebble interior goes in last.
Fill, start-up, and Pool School
We fill the spa, balance chemistry, light the heater, and walk you through the pad and the app on the day of start-up.
Hidden costs Long Beach homeowners miss
These line items show up on real Long Beach builds and rarely on a national cost blog:
Gas line upgrade. A standard 1/2-inch gas line will not feed a 400,000 BTU spa heater. A new 3/4-inch run from the meter adds $800 to $1,800.
Electrical sub-panel. No 240V capacity at the main panel means a sub-panel install at $400 to $1,800.
Plan check and permit. Building permit alone runs $100 to $250. Plan check, Title 24 review, and final inspection together can push total fees to $500 to $1,200.
Decking restoration. Excavation cracks adjacent decking. Patch and refinish runs $600 to $2,500 depending on material.
Initial fill and chemistry. A 400-gallon to 800-gallon fill plus startup chemistry runs $75 to $200 on the water bill and chemicals.
Crane delivery. Tight side yards in Bixby Knolls and Belmont Heights need a crane drop on prefab shells, $800 to $2,500 day rate.
Monthly cost to run an in-ground spa
Plan for $120 to $210 per month to keep a Long Beach spa swim-ready year-round. Five line items shape the monthly bill:
Electricity. $25 to $60 per month for a well-insulated spa run three to five days a week. Variable speed pumps cut this 30 to 40 percent versus single-speed gear.
Chemicals. $15 to $30 per month for chlorine or bromine, pH balancers, and sanitizer.
Filter cleanings. $50 to $150 per year for cartridge swaps or rinses every two to three months.
Quarterly water changes. Three to four full drain-and-fill cycles a year, $20 to $60 per cycle on the water bill.
Minor repairs. $200 to $500 per year is a fair planning number for jet, ozonator, or seal work that surfaces after year three.

What Long Beach customers say about the build
"Adam performed a pool control system upgrade for us, replacing our old wall unit with Pentair app for our phones. The app is easy to use and can turn lights, heater and water features on with a single click. Adam was very responsive when we needed a couple extra features installed."
"Adam's Pool and Spa service was communicative, competitively priced, timely, and professional at every step of my pool filter and salt water chlorinator install. Adam explained every piece of equipment and how to maintain it in a way that I could understand."
"We have used Adam' Pool and Spa since we built our pool 7 years ago. The service has been great and the pool is always clean and sparkling throughout the year. They are very good at helping us or answering any of our questions."

FAQ
Frequently asked questions about in-ground spa cost
Why is one quote $8,000 and another $40,000 for what sounds like the same project?
Quote variance comes from shell type, heater, jet count, automation, finish, and yard access. A prefab acrylic shell with electric heat and basic plaster sits at the low end. A custom gunite shell with raised spillway, twenty therapy jets, IntelliCenter, and pebble finish sits at the high end. Both are honest in-ground spa builds. Ask each builder for an itemized quote that names the shell, heater, pump count, finish, and automation. That is the only way to compare apples to apples.
Can I finance an in-ground spa instead of paying cash?
Yes. Most Long Beach buyers use one of three options: a HELOC against the home (lowest rate, longest paperwork), a contractor financing partner via the builder, or a personal loan. HELOC and contractor financing usually beat credit card rates for a $15,000 to $40,000 build. We can refer you to financing partners we have worked with, but we do not run financing in-house. Pick the option that matches your cash flow and tax situation.
Does an in-ground spa add value to a Long Beach home?
Usually yes when it is well built and well maintained. Appraisers in Long Beach typically add $5,000 to $15,000 in resale value for a permitted in-ground spa, and combos with a pool can add more. Daily-use lifestyle value is the bigger return. Spas that get used three to five times a week pay back faster than spas that sit covered for months.
Do I need a permit in Long Beach, and how much does that add?
Yes. Long Beach requires a building permit for an in-ground spa. The permit alone runs $100 to $250. Plan check, Title 24 energy review, and final inspection together push total fees to $500 to $1,200 on a typical residential build. We file the permit, meet the inspector at every required phase, and pull the final sign-off as part of the build.
How long does in-ground spa installation take?
Four to twelve weeks once the permit clears. Prefab inset shells run four to six weeks total. Standard gunite custom builds run six to eight weeks. Premium builds with raised spillways or full automation can run ten to twelve weeks. Plan check itself takes two to four weeks before any digging starts.
Is a prefab spa worth the savings, or do I regret it later?
Depends on the yard and the use case. Prefab acrylic shells are the right pick for a stand-alone spa on a clean side yard with a clear ten year horizon. Custom gunite is the right pick when you want a specific shape, integrated spillway, pool combo, or a thirty year asset. Most Long Beach buyers who plan to stay in the home pick gunite. Most buyers prepping for a sale pick prefab.
Do you service portable or above-ground hot tubs?
No. Adams works on in-ground spas only. If you have a portable or plug-and-play hot tub, we will refer you to a shop that handles those.

In-Ground Spa Cost Reference
Terms behind every in-ground spa quote
Shell, finish, pump, and heater set the four cost lines that decide every quote.
- Shotcrete
-
Concrete pneumatically projected at high velocity onto a steel rebar cage. Forms the structural shell of every gunite pool and is the construction method we use on new Long Beach builds.
- Variable-speed pump
-
A pool pump with a permanent-magnet motor that runs at adjustable speeds. Cuts pool electrical bills by 60 to 80 percent versus single-speed pumps and is required by California Title 24 on new builds.
- Heat pump
-
An electric pool heater that moves heat from the air into pool water. Lower operating cost than gas in mild Long Beach winters; longer warm-up time than gas.
- Plaster
-
The interior finish coat on a gunite pool, traditionally white marble plaster. Modern variants include color quartz and pebble aggregate. Lifespan is 8 to 15 years before replastering is needed.
