A plunge pool — compact, deep, and built for soaking and cooling off rather than swimming laps — typically costs $20,000 to $95,000+ installed. That’s an unusually wide range for a single pool category, and it exists for a real reason: “plunge pool” covers two genuinely different products. One is a smaller, simpler compact pool. The other is a full architectural inground build — concrete or premium fibreglass, full hardscape integration — just with a smaller footprint. Knowing which one you’re actually pricing matters more than almost anything else on this page.
How Much Does a Plunge Pool Cost? (Two Tiers)
| Tier | Typical Size | Typical Installed Cost | What You Get |
| Budget / Compact | 8’–12′ long | $20,000 – $45,000 | Simpler fibreglass or vinyl build, basic finish, minimal surrounding hardscape |
| Premium / Architectural | 10’–15′ long | $45,000 – $95,000+ | Full inground construction quality (often concrete), premium finish, integrated coping and decking, often heated |
Both are accurately described as “plunge pools” by different builders — which is exactly why getting an apples-to-apples quote means asking which tier a price actually reflects, not just comparing dollar figures.
Typical Plunge Pool Sizes
| Size Category | Approx. Dimensions | Typical Depth |
| Compact | 8′ x 10′ | 4–5 ft |
| Standard | 10′ x 14′ | 5–6 ft |
| Large | 12′ x 16’+ | 5–7 ft |
Plunge pools are built deeper relative to their footprint than a standard swimming pool, since the experience is about standing or soaking rather than swimming — which means excavation and structural cost don’t shrink as much as the small footprint might suggest. If you want a pool with at least a little room to swim a few strokes, Cost to Install a Small Pool covers that slightly larger category.
What Drives the Price Within Each Tier
- Material: fibreglass and vinyl builds tend to land in the budget tier; concrete (and premium fibreglass with custom finishes) drives the premium tier. See Cost to Install a Fibreglass Pool and Cost to Install a Concrete Pool for material-specific detail.
- Depth: a deeper soak-style plunge needs proportionally more excavation and structural reinforcement relative to its small surface area — the same fixed-cost logic that makes small pools cost more per square foot applies here too.
- Finish and hardscape integration: premium builds often integrate extensive stone coping, surrounding decking, and lighting directly into the design, which is where much of the cost above the budget tier actually goes.
- Heating: plunge pools are inexpensive to heat compared to a full-size pool, given how little water they hold — a real advantage if year-round or shoulder-season use matters to you.
- Site access: the small footprint is often an advantage on tight Toronto lots where a standard pool wouldn’t fit, sometimes avoiding the access surcharges larger pools face.
Adding Cold Plunge / Contrast Therapy Capability
A growing number of homeowners are pairing a heated plunge pool with a chiller, allowing the same pool to run hot for relaxation and cold for recovery and contrast therapy. This is a genuinely separate cost from the pool itself:
| Chiller Tier | Typical Unit Cost | Installation |
| Basic (smaller pools) | $2,000 – $4,000 | $500 – $2,500 |
| Mid-range (standard residential) | $4,000 – $7,000 | $500 – $2,500 |
| Premium, high-capacity inverter | $7,000 – $10,000+ | $500 – $2,500 |
It’s worth distinguishing this from a standalone portable cold plunge tub — the freestanding, self-contained units increasingly popular for cold therapy on their own, separate from a built backyard pool. Those typically run $1,000–$5,000+ for the unit alone and don’t require excavation or permits the way a plunge pool does. If cold therapy is your actual goal rather than a backyard feature, it’s worth comparing both routes before committing to a full plunge pool build.
What’s Typically Included in a Base Quote
A standard plunge pool quote covers excavation, the pool shell, plumbing, a pump and filter system sized for the smaller water volume, electrical connection, and basic coping. It generally excludes a heater, a chiller, premium finishes, decking, and fencing — priced as add-ons in both tiers.
Budget Factors Specific to Plunge Pools
- Permits and fencing still apply. Despite the small footprint, plunge pools deep enough to cross the bylaw threshold require the same pool enclosure compliance as any other pool. See Pool Permits Toronto and Toronto Pool Fence Bylaws.
- Small footprint, not small project. Permits, mobilization, and equipment minimums apply regardless of size — the same dynamic covered in our small pool cost guide.
- Crane or equipment access still matters for fibreglass plunge shells on tight lots, the same way it does for larger fibreglass pools.
Smart Budgeting Tips
- Clarify which tier you’re being quoted before comparing prices. A $25,000 quote and a $70,000 quote might both be accurately called “plunge pools” — ask what’s actually included in each.
- Decide if you want swim space or just soak space. If you’d like room for a few strokes, a small inground pool may serve you better than stretching a plunge pool’s dimensions.
- Compare a chiller-equipped plunge pool against a standalone cold plunge tub if contrast therapy is your main motivation — the tub route can be a fraction of the cost if you don’t need a built backyard feature.
- Ask whether heating is included. Given how cheap plunge pools are to heat relative to their size, it’s often worth adding even if it’s quoted separately.
Frequently Asked Questions
How much does a plunge pool cost?
Typically $20,000–$95,000+ installed, depending heavily on whether you’re looking at a simpler compact build or a full architectural-quality installation — the single biggest factor in the price.
What’s the difference between a plunge pool and a small pool?
A plunge pool is built specifically for soaking and cooling off — compact and deep, with little to no lap-swimming space. A small pool, by contrast, is a scaled-down version of a swimmable pool, generally with at least a little more room to move.
Can I add a chiller to my plunge pool for cold therapy?
Yes. Residential pool chillers typically cost $2,000–$10,000 for the unit plus $500–$2,500 installation, allowing the same pool to run warm for relaxation and cold for recovery.
Why is there such a big price range for plunge pools?
Because “plunge pool” describes two different products — a simpler, smaller compact build and a full architectural-quality inground installation — at very different price points. Always confirm which one a quote represents.
What size is a typical plunge pool?
Most fall between 8’x10′ (compact) and 12’x16’+ (large), with depths of 4–7 feet — deeper relative to their footprint than a standard swimming pool, since the experience is built around standing or soaking.
