Most Long Beach homeowners we sit down with think an in-ground hot tub costs about the same as a portable one. It doesn’t. The tub itself may be close in price. But excavation, concrete work, and electrical wiring add up fast. That’s the part people miss when they start planning.
Based on current industry estimates, a full in ground hot tub project typically runs between $6,000 and $25,000. The final number depends on whether you choose a prefab shell or a custom build, what features you add, and how much prep your yard needs.
This guide covers six things to know before you start:
- What an in-ground hot tub actually is
- How it compares to above-ground models
- What it costs (with a full breakdown)
- What the build process looks like step by step
- California permit and safety rules
- How long these spas last and whether they add home value

What Is an In-Ground Hot Tub?
An in-ground hot tub is a spa set into the ground or a deck. The rim sits level with the surface around it. It looks like part of your yard, not something placed on top of it.
There are two main types:
- Prefab (acrylic or fiberglass): A factory-made shell lowered into a hole. Faster to install. Comes with built-in seats and jets.
- Custom (concrete or gunite): Built on-site, like a small pool. You pick the shape, size, tile, and layout. Takes longer but gives you more control.
Here’s a quick look at what these spas include:
| Feature | Typical Range |
|---|---|
| Seat capacity | 2 to 8 people |
| Water temperature | Up to 104°F max |
| Common materials | Acrylic, concrete, stone, tile |
| Electrical | Dedicated 220V/240V circuit required |
| Estimated installed cost | $6,000 to $25,000+ |
These spas can stand alone or connect to a pool with a spillover edge. They work with decking, stone, and plantings for a clean, built-in look that a freestanding tub can’t match.
What we see most often: About half the spa projects we do in Long Beach connect to an existing pool. The other half are standalone tubs tucked into a patio or deck. Both look great when the materials match your outdoor space. We’ve had customers in Naples and Belmont Shore go back and forth for weeks, then pick the spillover combo every time once they see the finished product on a neighbor’s property.
What Makes an In-Ground Hot Tub Different from Above Ground?
The short answer: one is permanent, the other is portable. But the differences go deeper than that.
| Feature | In-Ground Hot Tub | Above-Ground Hot Tub |
|---|---|---|
| Installation | Built into the ground or deck | Sits on a pad or platform |
| Look | Blends into the yard | Visible above the surface |
| Custom options | Shape, tile, jets, waterfalls | Fixed shape and finish |
| Can you move it? | No, it’s permanent | Yes, it goes with you |
| Cost range | $6,000 to $25,000+ | $3,000 to $15,000 |
| Typical lifespan | 15 to 20 years | 5 to 15 years |
Here’s how the key differences break down:
- Design. In-ground spas blend right in. You can add LED lighting, a waterfall, or custom stonework that ties into your patio. Above-ground models sit on top of the surface and are harder to work into a finished outdoor space.
- Durability. A quality in-ground spa can last 15 to 20 years or more with proper care. Portable tubs generally last 5 to 15 years.
- Seating. In-ground tubs let you pick bench seats, lounge seats, or a custom layout. Portable models have fixed seating you can’t change.
- Resale. A built-in spa adds to your outdoor living space. A portable tub on a slab doesn’t carry the same weight with buyers.
Our honest take: We install both types. If you’re renting or plan to move in a few years, portable makes sense. But if you’re staying put in your Long Beach home and want something that feels like part of the property, in-ground is worth the extra cost. Southern California weather means you’ll use it 10 to 12 months a year. That kind of use makes the investment practical.
One thing we’ve learned after 15 years of spa work in this area: the benefits of in-ground hot tubs really show when you’re soaking every week, not just a handful of times each summer. Long Beach homeowners who invest in a built-in spa tend to use it far more than they expected.
How Much Does an In Ground Hot Tub Cost?
The cost of a hot tub depends on the type, your yard, the size you pick, and the finishes you want.
| Cost Category | Low Estimate | High Estimate |
|---|---|---|
| Hot tub unit (prefab, 4 to 6 seats) | $3,500 | $15,000 |
| Hot tub unit (concrete/gunite) | $8,000 | $20,000+ |
| Excavation and site prep | $400 | $2,500 |
| Concrete pad or base | $500 | $2,000 |
| Electrical wiring and hookup | $600 | $2,200 |
| Plumbing (often bundled with labor) | Varies | Varies |
| Building permit | $100 | $250 |
| Labor | $3,000 | $5,000 |
Estimated total: $6,000 to $25,000+ depending on scope and site. All figures are estimates. Permit fees are set by the city and may change. Check with Long Beach Development Services for current rates.
What pushes the price higher:
- More jets or swim jet capability
- Spillover into a pool
- Premium tile or stone finishes
- Longer electrical runs from your panel to the spa
- Difficult yard access (common in older Bixby Knolls and Los Altos homes with narrow side gates)
What we always tell people: Get two or three quotes. Make sure each one breaks out excavation, electrical, plumbing, and permits as separate line items. Some companies lump everything into one number, and you can’t tell what you’re paying for. We itemize every project so our customers can compare fairly. That’s just how we think it should be done.
Monthly operating costs:
| Expense | Estimated Monthly Range |
|---|---|
| Electricity (heating, pumps, jets) | $30 to $100 |
| Chemicals and filter supplies | $10 to $30 |
A tight-fitting cover and good insulation make the biggest difference in your monthly bill. We’ve watched customers cut their heating costs noticeably just by replacing a worn-out, waterlogged cover. It’s one of the cheapest upgrades you can make and it pays for itself fast.
What the Process Looks Like Step by Step
Here’s what a typical in-ground hot tub project looks like from start to finish. Every yard is a little different, but these are the main steps.
Step 1: Site evaluation
Your contractor walks the yard. They check access, look at soil, and measure the distance to your electrical panel. In many California cities, spas are typically required to be at least 5 feet from property lines. Local codes vary, so your contractor should check before drawing plans.
What we check first: Can we get equipment into the backyard? Older Long Beach homes in Bixby Knolls and Los Altos sometimes have narrow side yards or tight gate openings. We had one job near El Dorado Park where we had to bring materials through the neighbor’s yard because the side access was only 28 inches wide. We measure all of this before anything else because it affects the build plan and the cost.
Step 2: Permits and planning
A building permit is required for most in-ground projects in Long Beach. You submit plans showing the spa location, electrical layout, and drainage. An electrical permit is also needed for the dedicated 220V/240V circuit.
Step 3: Excavation and base prep
The crew digs the hole to the right depth and grade. Then they pour a concrete pad or reinforced base. This base needs to be strong. According to manufacturer specifications, a filled hot tub with water and people in it can weigh roughly 3,000 to 6,000 pounds.
Step 4: Setting the unit or building the shell
- Prefab: The factory-made shell is lowered into the hole and leveled.
- Custom: The spa is formed on-site with concrete or gunite. Plumbing, jets, and seating are placed during this step.
Step 5: Electrical hookup
A licensed electrician runs the dedicated circuit with GFCI protection. This is required by the California Electrical Code (based on NEC Article 680). This is not a DIY step.
Step 6: Finishing
The crew backfills around the spa, adds the deck or coping, and finishes landscape work. Lighting and water features go in now too. A city inspector does a final review before you fill and heat the water.
How long does it take?
| Project Type | Typical Timeline |
|---|---|
| Prefab install | About 1 to 3 weeks |
| Custom build | About 4 to 8 weeks or more |
These timelines don’t include permit processing, which can add extra time.
Why we do it all in-house: Our team handles electrical, plumbing, and gas lines ourselves. You don’t have to call three different contractors and hope their schedules line up. That’s one of the biggest headaches we hear about from homeowners who tried to manage it on their own. One customer in Lakewood told us he waited six weeks just to get an electrician scheduled after his builder finished. With us, that step is already built into the project.
Permits and Safety Rules for In-Ground Hot Tubs in California
California has rules for in-ground spa projects. Here’s what to plan for before you break ground.
| Requirement | What It Means |
|---|---|
| Building permit | Required in most California cities, including Long Beach |
| Electrical permit | Separate from building permit; needed for the 220V/240V circuit |
| GFCI protection | Required on all spa circuits per NEC Article 680 |
| Safety cover or barrier | Locking cover or approved fence required around in-ground spas |
| Anti-entrapment drains | Required on all residential spas per CA safety requirements |
| Setbacks | Typically at least 5 feet from property lines (varies by city) |
| Water temperature | Max 104°F per CDC guidelines |
| Water chemistry | Chlorine 3 to 5 ppm, pH 7.0 to 7.8 per CDC guidelines |
A few things Long Beach homeowners should know:
- HOA approval. If you live in a community like Rossmoor or Naples, your HOA may have its own review process. Check with them before you submit permit applications to the city.
- Permit timeline. Long Beach Development Services handles permits. Build extra time into your schedule for plan review and approvals.
- Separate inspections. Electrical work is inspected separately from the structure. Plan for at least two inspection visits.
A common mistake we see: Homeowners start shopping for the spa before checking their electrical panel. If your panel is full or undersized, upgrading it adds cost and time. We had a customer in Seal Beach who picked out her dream spa, got the permits rolling, then found out her panel needed a $2,000 upgrade before a single wire could be run. We always check panel capacity on the first site visit so there are no surprises like that later.
Maintenance and How Long In-Ground Hot Tubs Last
Spa upkeep is simple once you learn the routine. The time you spend on maintenance is small compared to the years of use you get. Good care protects your investment and keeps the water safe for your family.
Your maintenance schedule at a glance:
| Task | How Often |
|---|---|
| Test water chemistry (chlorine, pH) | 2 to 3 times per week |
| Rinse or clean filter cartridge | Every few weeks |
| Drain, scrub, and refill the tub | Every 3 to 4 months |
| Replace filter cartridge | Every 12 to 24 months |
| Replace cover | Every 3 to 7 years |
Key details on each task:
- Water chemistry. Keep chlorine between 3 and 5 ppm and pH between 7.0 and 7.8. Test 2 to 3 times per week. Unbalanced water damages walls and irritates skin.
- Draining. Manufacturers recommend draining every 3 to 4 months. Scrub the shell, check the jets, and refill with fresh water.
- Filters. A dirty filter makes the pump work harder and the water look cloudy. Clean it often and replace every 12 to 24 months.
- Covers. A snug cover cuts heat loss and keeps debris out. Most covers last 3 to 7 years before the foam gets heavy and waterlogged.
Monthly cost estimates:
| Expense | Estimated Range |
|---|---|
| Electricity | $30 to $100/month |
| Chemicals and supplies | $10 to $30/month |
How long do in-ground hot tubs last?
A well-maintained in-ground spa can last 15 to 20 years or more. Balanced water chemistry and regular service are what keep the structure and plumbing in good shape over time.
Coastal Long Beach tip: Salt air along Belmont Shore, Alamitos Bay, and the Peninsula speeds up corrosion on metal parts like heaters and fittings. We see it every week on service calls. Stainless steel that would last a decade inland can start showing rust in three or four years near the water. We recommend corrosion-resistant hardware for any home within a mile or two of the coast, and more frequent equipment checks.
Why we teach “Pool School” for spas too: We spend time with every new spa customer showing them how water chemistry works, what the filter does, and what to watch for between visits. It takes about 30 to 40 minutes. Most people tell us it’s the first time anyone actually explained how their spa works. That knowledge saves real money. A $5 test kit used twice a week catches problems early. That’s a lot cheaper than a $500 repair call six months down the road.
Does an In-Ground Hot Tub Add Home Value?
An in-ground hot tub can make your home more appealing to buyers. But it’s not a guaranteed return like a new kitchen. There’s no widely published ROI figure specific to hot tub additions. The value depends on your local market, how well the spa fits the yard, and the quality of the build.
What matters most for resale:
- Integration. A spa that matches the deck, hardscape, and landscaping looks planned. A portable tub on a concrete slab does not.
- Condition. A clean, well-maintained spa with working equipment is an asset. A neglected one is a red flag for buyers.
- Neighborhood expectations. Buyers in Long Beach neighborhoods like Belmont Shore, Naples, and Seal Beach often expect a pool and spa combo. In those areas, a built-in spa adds to the property. In other neighborhoods, it may matter less.
What we’ve seen over 15 years: The homeowners who get the most value from a built-in spa are the ones who use it often and keep it up. We had a customer in Belmont Heights who used her spa almost every evening for twelve years before selling. She told us the buyers specifically mentioned the spa as one of the reasons they made their offer. That’s not unusual down by the water, where outdoor living space is part of what people pay for.
The lifestyle side is real too. Warm water therapy after a long day. A quiet soak on a cool January evening near the coast. A place to sit and unwind before bed. Those things don’t show up on a spreadsheet, but they’re what our customers bring up most when we ask if the spa was worth it.
With a potential lifespan of 15 to 20 years based on manufacturer estimates, the yearly cost of an inground spa becomes very reasonable. And if you’re already planning a pool build or backyard remodel, adding a spa during construction is typically cheaper than doing it as a separate project later.

FAQs About In-Ground Hot Tubs
Q: What are the main benefits of in-ground hot tubs and how do they compare to a portable hot tub?
A: In-ground spas offer a built-in, luxurious look that can integrate seamlessly with your backyard design and surround, creating a backyard oasis. They often provide better ergonomic seating, custom-built contour options, and can be finished with durable materials like acrylic or tile. Portable hot tubs are more flexible, easier to move, and typically lower initial cost, but in-ground units can offer superior hydrotherapy, massage jet placement, and long-term value. Talk to a dealer about what spas hot tubs and swim spas best fit your needs and budget.
Q: How does installation of an inground spa differ from an above-ground hot tub or a built-in spa package?
A: Installation for an inground spa or built-in spa is typically more involved than an above-ground hot tub or a portable hot tub. In-ground requires excavation, proper base preparation, often custom-built structural support, plumbing and electrical hookup, and sometimes a spillover or swim integration. Above-ground tubs have simpler setup and lower setup costs. A dealer can provide a package quote including delivery, installation, and any site work to help you decide if an in-ground hot is right for you.
Q: What factors will help me decide if I want a hot tub or a swim spa for my backyard?
A: Consider space, intended use (relaxation and massage versus exercise and swim), budget, and backyard design. Swim spas allow for continuous swim current and are great for fitness; smaller spas focus on massage jets and hydrotherapy. Think about how a unit will compliment landscape, whether you want a built-in, spillover feature, or a portable option. Dealers can show configurations and packages so you can compare best prices and benefits of owning each type.
Q: How much does a luxury in-ground spa typically cost and what affects the price?
A: Prices vary from modest ground hot models to custom luxury installations. Key cost factors include size, acrylic or other finish, number and quality of jets, plumbing and electrical complexity, excavation, and whether you choose a dealer-installed package or custom-built design. Accessories, decking, and landscaping to integrate the spa into your backyard oasis will also affect the final total. Tubs can also have options for advanced hydrotherapy systems that raise the price.
Q: Are there long-term maintenance and durability differences between inground and above-ground hot tubs?
A: In-ground spas, when properly installed, can be very durable and integrate well with surrounding hardscape, but repairs to shell or plumbing may be more complex. Acrylic shells are common and long-lasting if cared for. Above-ground and portable hot tubs are easier to access for repairs and replacement. Regular maintenance like water chemistry, filter care, and winterizing are common to all spas hot tubs to preserve luxury finish and therapeutic benefits.
Q: Can a dealer help customize my spa design and recommend the best jet and massage configuration?
A: Yes, a reputable dealer or designer will review your backyard, lifestyle goals, and therapeutic needs to recommend jet placement, ergonomic seating, and massage packages that provide the best hydrotherapy. They can suggest upgrades like additional jets, spillover features, or swim spa options to create a luxurious, therapeutic bath experience and help you decide between prebuilt packages or a custom-built solution.
Q: What permits or site preparations are required for in-ground spa installation?
A: Site prep typically includes excavation, a stable base (concrete or compacted gravel), proper drainage, and compliant electrical and plumbing work by licensed professionals. Local building permits may be required depending on size and modifications to utilities. A dealer or installer can advise on permit needs, access for delivery, and how to best integrate the spa with your backyard design to meet safety and code requirements.
Q: How do I choose between a round spa, swim spa, or a custom contour in-ground design for therapeutic use?
A: Decide based on intended use: round spa shapes are social and compact; swim spas offer exercise and therapeutic resistance; custom contour designs can target specific ergonomic and massage needs. Consider factors like available space, desired massage and hydrotherapy features, and whether you want a built-in or portable option. Discuss options with a dealer to find a configuration that balances relaxation, therapeutic benefits of owning a spa, and the best prices for your package.
