Plunge Pool and Cold Plunge Guide: Costs, Types, and Smart Picks

A plunge pool is a small, deep pool designed for quick dips or relaxation, while a cold plunge is kept at a much lower temperature for recovery and therapy.

Cold plunges are small tubs designed to stay between 50°F and 59°F. Athletes use them to reduce inflammation, ease soreness, and boost mood after workouts. A 2024 study from the National Library of Medicine found that just two minutes of cold immersion can lower muscle fatigue by up to 25%.

This guide helps you compare costs, sizes, and features, so you can choose the right one for your space, wellness goals, and budget without wasting time or money.

What Is a Plunge Pool Anyway?

A deep pool designed more for cooling off and relaxation than swimming laps. They’re usually compact (often 6 to 12 feet long and 4 to 7 feet deep), which makes them a popular pick for backyards that don’t have room for a full-size pool. You can soak, stretch, or chill without needing much space or water.

Some folks use them for cold plunging after workouts. Others treat them like a mini backyard escape, maybe with a waterfall, some mood lighting, and a glass of something chilled in hand. You can heat them, cool them, or just enjoy them at ambient temperature, depending on your setup.

Now, if you’re seeing the term used in travel or nature contexts, it might refer to something else entirely. A plunge pool in geography means a natural pool found at the base of a waterfall. It forms when fast-moving water erodes the rock below, creating a basin that can be surprisingly deep, even if the waterfall isn’t that tall.

Here’s how the two compare:

Type of Plunge Pool	Description	Common Use
Backyard/Home	Small, man-made, often heated or cooled	Relaxation, hydrotherapy
Geographic/Natural	Deep basin formed at base of a waterfall	Natural swimming, sightseeing

Quick Facts at a Glance:

• Depth: Typically 4 to 7 feet
• Length: Often 6 to 12 feet
• Purpose: Cooling off, soaking, cold therapy, visual appeal
• Ideal For: Small yards, spa-like setups, wellness routines

People often pair plunge pools with modern landscaping or tuck them into patios. They’re also showing up more in boutique hotels, spas, and vacation rentals.

Cold Plunge vs Cocktail vs Regular Pools: What’s the Difference?

Cold plunge tubs are best for recovery and wellness. Plunge pools work for compact relaxation, and cocktail pools are ideal for social soaking with friends.

🧊 Cold Plunge Pool (or Cold Plunge Tub)

Cold plunges are exactly what they sound like: tubs or small pools designed to hold water around 50°F to 59°F. They’re built for short, intentional dips that help reduce inflammation, speed up recovery, and even improve mood. You’ll often see them in gyms, spas, or high-performance training facilities.

• Size: Usually built for one person, though some seat two
• Features: Cooling systems, durable materials, sometimes portable
• Best for: Athletes, wellness routines, post-sauna use

🌡️ Standard Plunge Pool

A plunge pool is a bit of a middle ground. It’s a compact, deep pool designed more for soaking or cooling off than full-on swimming. Unlike cold plunge tubs, they can be either heated or unheated, depending on how you want to use them. They’re a favorite for smaller backyards or patios with limited space.

• Size: Often 6 to 12 feet long, 4 to 7 feet deep
• Features: Optional heaters, basic filtration, sometimes jets
• Best for: Relaxation, space-conscious homeowners, spa vibes

🍸 Cocktail Pool

Cocktail pools are like the social butterfly version of a plunge pool. They’re slightly larger, typically come heated, and often include jets, seating, and lighting. Think of them as a mini-pool-slash-hot-tub made for entertaining.

• Size: Small to medium, often wider than plunge pools
• Features: Jets, built-in benches, heaters, LED lights
• Best for: Hosting, lounging, evening dips with drinks

📋 Side-by-Side Comparison

Feature	Cold Plunge	Plunge Pool	Cocktail Pool
Temp	Cold only	Warm or cold	Warm
Size	Small	Small	Small to medium
Jets	Rare	Optional	Usually included
Purpose	Therapy (recovery)	Cooling, soaking	Relaxation, entertaining

No one-size-fits-all here. If recovery and routine are your thing, a cold plunge might be perfect. Want something chill and compact that can be hot or cold? Go for a plunge pool. If your dream setup includes soaking with friends and drinks, cocktail pool’s the move.

Plunge Pool Sizes, Shapes & Layouts

Plunge pools aren’t one-size-fits-all, but they are designed with space-saving in mind. Whether you’re working with a tiny backyard or an open patio, the right setup can feel like a luxury spa without eating up your entire outdoor space.

Typical Plunge Pool Dimensions

Most plunge pools fall into the following size range:

Dimension	Typical Range
Length	6 to 12 feet
Width	5 to 8 feet
Depth	4 to 7 feet

They’re deep enough for a full-body soak but short enough to fit into tight spaces. Some are square, others rectangular, and a few even come with curved edges or corner-friendly shapes.

Inground vs Above Ground

Inground Plunge Pools

• Blends in with landscaping
• Offers a sleek, high-end look
• Often more durable long term
• Requires excavation and permits
• Higher installation cost

Above Ground Plunge Pools

• Easier and faster to install
• Works well on decks, patios, or tight slopes
• Can be wrapped in wood, tile, or composite panels for aesthetics
• Typically more budget-friendly
• May require extra reinforcement or framing

Pro Tip: If your yard has elevation changes or limited access for heavy equipment, above ground can save you a headache.

Prefab vs Custom vs DIY

Option	What It Means	Pros	Considerations
Prefab	Pre-built shell delivered ready to install	Fast, predictable costs	Limited size/style options
Custom	Built on-site to your specs	Fully tailored to your space	More expensive, longer timeline
DIY Kits	You install it yourself from a kit	Saves money if you’re handy	Requires tools, permits, know-how

Prefab plunge pools are booming in popularity thanks to their simplicity and modern look. Many even come with built-in steps or seating.

🏡 Smart Layout Ideas for Small Yards

• Corner installs: Great for L-shaped patios or underused yard edges
• Deck integration: Drop it into a deck for a flush, built-in look
• Partial in-ground: Split the difference for style and access
• Side-yard setups: Use the long, narrow side of the house for privacy

You can get creative with surrounding features too, like a small waterfall wall, privacy fencing, or integrated planters.

Cost Breakdown & Buying Guide

If you’re sizing up whether a plunge pool is worth the investment, it helps to look at real numbers and long-term costs. Prices can swing quite a bit depending on whether you’re going for a prefab shell, a custom build, or a cold plunge tub.

Average Price Ranges

Here’s a snapshot of what you might spend on different types of plunge pools:

Type	Base Cost Range	Installed Cost (Approx.)
Cold Plunge Tub	$600 to $2,500	Usually DIY or plug-in
Prefab Plunge Pool	$3,000 to $10,000	$5,000 to $15,000 installed
Custom Inground Pool	$15,000 and up	$20,000 to $35,000+

These numbers cover the basics, like the shell, delivery, and standard plumbing. Custom finishes, heating systems, and decking can push costs higher.

🛠️ Installation vs DIY

Prefab and Cold Plunge Tubs

• Easier to handle without a pro crew
• Many models plug into a standard outlet
• Site prep still adds cost (like leveling, electrical wiring, or a concrete pad)

Inground Custom Plunge Pools

• Requires excavation, plumbing, and permits
• Almost always needs a licensed contractor
• Timeline is longer (6 to 12 weeks in many areas)

If you’re handy and have time, prefab plunge pools or cold tubs can be installed with basic tools. But for anything inground, expect professional help.

Maintenance Costs Over Time

Even small pools come with upkeep. Here’s what you’ll need to budget for each year:

• Chemicals: $200–$500
• Electricity (pumps, heaters): $300–$1,000
• Cleaning supplies or services: $150–$500
• Miscellaneous repairs: Varies

Cold plunge tubs cost less to maintain since they hold less water and typically don’t need as many chemicals.

Use Cases and Value

People usually buy plunge pools for different reasons, and each has its own payoff.

• Wellness and Recovery: Cold plunging helps reduce inflammation and improve circulation.
• Summer Cooling: Even unheated plunge pools are a relief on hot days.
• Luxury Feel: A sleek, modern plunge pool boosts backyard appeal.
• Space-Saving: Ideal for small yards or side-yard installs.

Pros, Cons & Who It’s Not For

Plunge pools check a lot of boxes, especially for people working with smaller outdoor spaces or looking to add a bit of luxury without the cost of a full-size pool. That said, they’re not perfect for every situation.

Here’s what works and what doesn’t.

Pros of a Plunge Pool

• Space-Saving: Most plunge pools are small enough to fit in tight backyards, patios, or side yards where a traditional pool wouldn’t make sense.
• Easier to Clean: Less water means quicker clean-ups, fewer chemicals, and lower maintenance overall.
• Wellness Benefits: Cold plunge options are great for recovery, circulation, and inflammation. Heated versions offer a spa-like soaking experience.
• Energy Efficient: Smaller volume = less heating or cooling time and lower utility bills.
• Modern Appeal: Compact pools with clean lines and water features can seriously upgrade your outdoor design.

Cons of a Plunge Pool

• Not Made for Swimming: If you’re imagining doing laps, a plunge pool isn’t it. These are made for soaking, not strokes.
• Still Can Be Pricey: High-end finishes, custom installs, or combining with hot tubs can push the budget up fast.
• Limited Capacity: Most plunge pools seat 2 to 4 people comfortably. They’re not built for big social gatherings or pool parties.
• Cold Water Shock Risk: For cold plunges, the water temp can be a shock to the system—something to consider if you have circulation or heart concerns.

Who Should Think Twice Before Getting One

Type of User	Why It Might Not Be a Good Fit
People with heart conditions	Cold immersion can stress the cardiovascular system
Lap swimmers	Not enough space for proper swimming
Party hosts	Too small to entertain large groups comfortably
Those on a tight budget	Even the basics can cost several thousand dollars

If you’re after a space to host summer pool parties or want a workout zone for serious swimming, a plunge pool may leave you underwhelmed.

💡 Still thinking it might work for your space and goals? Here’s what it takes to clean and maintain one without the hassle, so you know what you’re signing up for.

Which Option Fits Your Lifestyle?

Not sure which plunge-style setup fits your life (and your wallet)? Here’s a simple way to decide.

Your Goal	Best Option
Muscle recovery	Cold plunge tub
Backyard lounging	Inground plunge pool
Budget-friendly	Above ground or prefab plunge pool
Entertaining guests	Cocktail pool
Luxury spa vibe	Heated plunge with a waterfall

According to the Pool & Hot Tub Alliance, there are about 10.7 million residential swimming pools in the U.S., and smaller, wellness-focused installs like plunge pools are becoming one of the fastest-growing segments as homeowners look for compact spa-style options.

A University of South Australia study reviewed dozens of cold-water immersion sessions and found that short plunges (20–90 seconds at 50–59°F) improved stress levels and overall well-being. The researchers noted the effects last a few months but show clear short-term benefits for recovery and mood.

How to Install a Plunge Pool (Step-by-Step)

Thinking about adding one yourself? Here’s a simple breakdown of what the process looks like, whether you’re going prefab or custom.

Step 1: Pick Your Spot

Choose a level area with easy access to water and electricity. Aim for at least 3 feet of clearance around the pool for maintenance and decking.

Step 2: Choose Your Pool Type

Decide between prefab, custom, or cold plunge tub. Prefab is fastest (2–3 days to install), while custom builds can take 6–10 weeks.

Step 3: Prep the Site

Clear the area, level the ground, and add a compacted gravel base or a small concrete pad for stability.

Step 4: Plumbing and Electrical Setup

Run plumbing lines for filling and draining. If you’re adding a heater or chiller, use a licensed electrician to handle wiring safely.

Step 5: Install the Pool

Lower the shell into place (with help or machinery, depending on size). Connect plumbing, add insulation if needed, and fill it up.

Step 6: Finishing Touches

Add decking, landscaping, or seating. Test water balance and filtration before your first dip.

Pro Tip:
If you’re using a prefab plunge pool, most brands include a setup video or online guide. Always double-check warranty conditions before DIY installs.

Real Example: Homeowner Case Study

Sarah from Austin, TX added a prefab plunge pool to her side yard for just under $8,000, including delivery and setup.

“It’s honestly the best part of summer evenings,” she says. “I use it after my runs three or four times a week, and the cold plunge makes recovery so much faster.”

Her setup takes up less than 100 square feet and blends into a small deck area with privacy panels and string lights. Maintenance is simple, she spends about 10 minutes a week checking the filter and adjusting the water balance.
