Pool Spas & Hot Tubs in Jacksonville
Pool Spas & Hot Tubs in Jacksonville: Your Options
When adding a spa or hot tub to your Jacksonville backyard, you have three main options:
a freestanding spa (a self-contained hot tub that sits separately on your patio),
an attached spa (built into the pool's edge, usually raised so it spills into the pool), or
a fully integrated spa (custom-built into a luxury pool design with shared automation and water features).
They range widely in cost — a quality freestanding spa can start around $3,000–$8,000, while an attached or integrated spa built into the pool typically adds $15,000–$30,000+ to the project.
If budget and practicality matter, a freestanding spa is often the smartest choice — it costs a fraction of an integrated one and, as we found with our own, can actually be more private and comfortable to use.
The three types of pool spas
1. Freestanding spa (standalone hot tub) A self-contained unit that sits on your patio or deck, separate from the pool. It plugs in, holds its own water and heater, and can be placed wherever's convenient. This is the most economical option by far, and it doesn't require building anything into the pool.
2. Attached spa (spa that spills into the pool) Built right into the pool's structure, usually raised a step above the water so it "spills" or sheeters into the pool. It shares the pool's equipment and water, and it's a big step up in look and cohesion — this is the classic "pool and spa combo." It's a Custom-tier feature.
3. Fully integrated spa (luxury) A spa designed as part of a high-end custom pool — integrated into the geometry, with shared automation, custom stone or tile, and often multiple water and fire features. This is the premium, resort-style option and a Luxury-tier feature.

What spas cost
| Spa type | Typical cost | What you get |
|---|---|---|
| Freestanding spa Most economical |
~$3,000–$8,000+ | Standalone hot tub, no pool construction needed |
| Attached spa (spills into pool) | ~$15,000–$25,000+ added to the build | Raised spa built into the pool, shared water/equipment |
| Fully integrated (luxury) | ~$25,000–$30,000+ added | Custom-designed spa with automation and features |
A freestanding spa costs a fraction of a built-in one and can be placed for more privacy and flexibility. Built-in spas cost more but give the cohesive pool-and-spa look many custom builds want. Costs are estimates — confirm with your builder.
The gap is significant: an attached or integrated spa can cost several times more than a quality freestanding unit, because it involves custom construction, plumbing, and finishing as part of the pool build.
The money-saving move: a freestanding spa (our experience)
Here's some honest advice you won't hear from a builder trying to sell you a bigger project: if cost is a real consideration, a freestanding spa is hard to beat — and it can actually be the more practical choice.
We went this route with our own pool, and it worked out great. We picked up a brand-new quality freestanding spa for around $3,500 (Costco and similar retailers carry surprisingly good units at these prices). Compared to spending $15,000–$30,000 to build a spa into the pool, the savings are enormous — and the experience is arguably better in a few ways:
More privacy. We placed ours in a sheltered spot rather than out in the open middle of the backyard. You can tuck a freestanding spa next to the house, on a covered patio, or in a screened area — closer to the kitchen and indoors, where you can pop inside easily and even close blinds for privacy. An attached spa is fixed out in the open by the pool.
More comfortable, year-round. Freestanding spas hold heat efficiently with insulated covers and are built for comfort — molded seats, jets, easy year-round use — without heating the whole pool.
Flexible placement. You choose where it goes, and you can even move it later. An integrated spa is permanent and fixed.
Far cheaper to run and maintain as its own small, well-insulated unit.
None of this means an attached or integrated spa is a bad choice — a spa that spills into the pool looks beautiful and is exactly right for many custom builds. But if you're weighing economical and practical, don't assume you need to build the spa into the pool.
A freestanding unit can deliver most of the enjoyment for a fraction of the cost, with more privacy and flexibility.
Hot tub vs. spa: is there a difference?
People use the terms interchangeably, and for backyard purposes they basically mean the same thing — a heated tub with jets for relaxation. Technically, "hot tub" once referred to standalone units and "spa" to built-in ones, but today both words are used for both. What matters isn't the label; it's the three options above (freestanding, attached, integrated) and which fits your space and budget.
Which spa is right for you?
Choose a freestanding spa if budget and practicality are priorities — it's dramatically cheaper, more private and flexible, and quick to add. Great for most homeowners who want the hot-tub experience without a big custom build.
Choose an attached spa if you want the cohesive "pool and spa combo" look, with the spa spilling into the pool, and it fits your budget (a Custom-tier feature).
Choose a fully integrated spa if you're building a luxury, resort-style pool and want the spa designed seamlessly into it with premium features (a Luxury-tier feature).
Spas and Hot Tubs FAQ
How much does it cost to add a spa to a pool?
It depends on the type. A freestanding spa (standalone hot tub) can start around $3,000–$8,000. An attached spa built into the pool that spills into it typically adds $15,000–$25,000+ to the project, and a fully integrated luxury spa can add $25,000–$30,000 or more. A freestanding spa is by far the most economical option.
Is a freestanding spa or a built-in spa better?
Both are good, but for budget and practicality a freestanding spa is often the smarter choice — it costs a fraction of a built-in spa, can be placed in a more private or sheltered spot, and is flexible to move or upgrade. A built-in (attached or integrated) spa costs much more but gives the cohesive pool-and-spa look many custom builds want.
What's the difference between a hot tub and a spa?
For backyard purposes, they mean essentially the same thing — a heated tub with jets. "Hot tub" once referred to standalone units and "spa" to built-in ones, but today the terms are used interchangeably. What matters is whether it's freestanding, attached to the pool, or fully integrated.
Can you add a spa to a pool later?
A freestanding spa can be added anytime — it's a standalone purchase you just place on your patio. An attached or integrated spa is much harder and more expensive to add after the pool is built, since it's part of the pool's structure, so it's best decided during the original build.
What's the cheapest way to get a hot tub with a pool?
A quality freestanding spa is the cheapest route — units start in the low thousands (often $3,000–$8,000 new), versus $15,000–$30,000+ to build a spa into the pool. It also gives you flexibility in placement and privacy.
