When deciding between a plunge pool and a hot tub for your home, it’s important to understand the key differences between these two popular options.
Plunge pools are generally larger than hot tubs and use more water due to their size and higher evaporation rates. They’re typically kept at cooler temperatures and are designed for quick, refreshing dips rather than extended soaking sessions.
Hot tubs are smaller, more energy-efficient options that provide warm water and therapeutic jets, while plunge pools offer more space for light swimming and cooling off.
The choice between them often comes down to your available space, intended use, and personal preferences. Hot tubs are great for relaxation and therapy, while plunge pools offer flexibility in temperature and more room to move around.
We’ve found that installation requirements differ as well. Plunge pools offer more flexibility with pump placement, which can be either above or below the waterline.
Meanwhile, hot tubs typically come as pre-fabricated units that require less construction work but offer fewer customization options. Both can fit in smaller spaces, though plunge pools generally need a bit more room than a standard hot tub.

What’s the Difference Between a Plunge Pool and a Hot Tub?
Plunge pools and hot tubs serve different purposes despite both being water features for your home. The main differences lie in their size, depth, temperature, and intended use.
Key Features and Functions of a Plunge Pool
A plunge pool is typically larger and deeper than a hot tub, with a consistent depth throughout. These pools are usually between 4-7 feet deep and can range from 10-15 feet in length.
Plunge pools are primarily designed for cooling off and light exercise. Unlike traditional swimming pools, they don’t have shallow and deep ends.
Many people use plunge pools for resistance swimming or simply to relax in cool water after exercise or on hot days. They’re often kept at cooler temperatures, though some can be heated.
The design of plunge pools is typically more minimalist compared to hot tubs. They don’t usually come with jets or bubbling features, focusing instead on providing a small but functional swimming space.
What Defines a Hot Tub (or Jacuzzi)?
Hot tubs are smaller, shallower water features designed primarily for relaxation and hydrotherapy. They typically hold 2-8 people and maintain higher temperatures between 100-104°F.
The signature feature of hot tubs is their jets. These powerful water streams provide massage-like sensations that can help relieve muscle tension and stress.
Most hot tubs include built-in seating with various jet configurations targeting different body areas. They’re meant for sitting rather than swimming or standing.
Jacuzzi is actually a brand name that has become synonymous with hot tubs, similar to how Kleenex refers to tissues. All Jacuzzis are hot tubs, but not all hot tubs are made by the Jacuzzi company.
Dip Pool vs Jacuzzi: Are They the Same as Plunge Pools and Hot Tubs?
Dip pools and plunge pools are essentially the same thing. Both terms refer to small, typically cool pools designed for quick immersion rather than extended swimming.
The main difference between terminology comes from regional preferences. “Dip pool” might be more commonly used in some areas, while “plunge pool” is the standard term in others.
Unlike hot tubs or Jacuzzis, dip pools don’t usually feature jets or bubbling systems. They’re focused on providing a refreshing cool-water experience rather than heated therapy.
In resorts, a plunge pool typically refers to a small private pool that isn’t heated like a hot tub. As one search result notes, “a plunge pool will never be a bubbling jacuzzi/hot tub” in resort settings.
The choice between a dip pool and a hot tub ultimately depends on your preferences for temperature, activity level, and intended use.
Pros and Cons of Plunge Pools
Plunge pools offer unique benefits and challenges compared to hot tubs. They provide refreshing immersion in cooler water and typically require less complex maintenance due to simpler systems.
Cooling Effect and Recovery Benefits
Plunge pools are specifically designed for cooling the body, which offers significant recovery benefits for athletes and active individuals. The cold water immersion helps reduce inflammation and muscle soreness after intense workouts.
Many users report improved circulation and decreased recovery time when regularly using a plunge pool. The cold water triggers vasoconstriction followed by vasodilation, which can help flush metabolic waste from muscles.
Unlike hot tubs that relax muscles through heat, plunge pools invigorate the body through cold therapy. This cold exposure can also boost immunity and mental alertness.
Some plunge pools can be temperature-controlled, allowing for year-round use and customized cold therapy sessions.
Size, Cost, and Maintenance Overview
Plunge pools are typically smaller than standard swimming pools, measuring around 6-10 feet long and 4-6 feet wide. This compact size makes them ideal for smaller yards or spaces where a full pool won’t fit.
Installation costs for plunge pools range from $10,000 to $25,000, generally less expensive than full-sized pools but often comparable to quality hot tubs.
Plunge pools require less maintenance than hot tubs due to their simpler features and fewer mechanical components that might break down. They typically use standard pool chemicals for water treatment.
The simpler system means lower operational costs and fewer repair needs over time. Most plunge pools use standard filtration systems that are easy to maintain.
Installation is usually quicker than traditional pools, taking days rather than weeks to complete in many cases.
Pros and Cons of Hot Tubs
Hot tubs offer distinct advantages and disadvantages compared to plunge pools. They excel at therapeutic benefits but come with specific maintenance requirements and space considerations.
Relaxation and Hydrotherapy Advantages
Hot tubs provide exceptional hydrotherapy benefits through powerful jets that massage sore muscles and joints. The warm water (typically 100-104°F) increases blood circulation and helps relieve stress and tension.
Many models feature ergonomic seating with strategically placed jets targeting different muscle groups. This makes them ideal for people with arthritis, fibromyalgia, or sports injuries.
Hot tubs can be used year-round, even in cold climates, offering a consistent relaxation experience regardless of weather. The buoyancy of water reduces body weight by approximately 90%, decreasing pressure on joints.
Most modern hot tubs include customizable jet settings, allowing users to adjust the intensity of their massage experience. Some even offer aromatherapy options to enhance relaxation further.
Energy Use, Space Requirements, and Upkeep
Hot tubs generally require less water than plunge pools, with most models holding between 300-500 gallons. They also need less space, making them suitable for smaller yards or decks.
The ongoing energy costs can be significant, especially in colder months. A well-insulated hot tub typically costs $20-50 per month in electricity, depending on usage and local rates.
Maintenance includes regular water testing, chemical balancing, and filter cleaning. The water needs changing every 3-4 months, which is more frequent than plunge pools.
Most hot tubs require a dedicated 220V electrical circuit, potentially increasing installation costs. Their covers help retain heat but need replacement every 3-5 years.
The smaller water volume means chemicals must be monitored more carefully to maintain proper balance and prevent skin irritation or equipment damage.
Plunge Pool vs Jacuzzi: How Do They Compare Side by Side?
Plunge pools and Jacuzzis serve different purposes in backyard relaxation. They differ significantly in temperature, installation requirements, health benefits, and costs that affect which option might be right for you.
Installation Requirements and Backyard Fit
Plunge pools typically require more space than hot tubs. A standard plunge pool measures between 8 to 10 feet in length and 4 to 7 feet in width, needing a larger backyard footprint. These pools are often installed in-ground, which involves excavation and more complex installation.
Hot tubs, on the other hand, are more compact. Most models range from 5 to 9 feet across and can be installed above-ground with minimal site preparation. This makes them suitable for smaller yards or even decks that can support their weight.
Both options need access to electricity, but hot tubs require more robust electrical systems to power heaters and jets. Plunge pools may need less electrical work unless heated, but often require more extensive plumbing infrastructure and possibly permits.
Health Benefits: Hot vs Cold Immersion
Hot tubs offer therapeutic benefits through warm water immersion (typically 100-104°F). The heat helps relax muscles, improve circulation, and reduce stress. The massaging jets can target specific muscle groups to relieve tension and soreness.
Plunge pools are often kept at cooler temperatures (50-70°F) and provide different health advantages. Cold water immersion can reduce inflammation, speed muscle recovery after workouts, and improve circulation through vasoconstriction followed by vasodilation.
Athletes often use both in combination: hot immersion to relax before activity and cold immersion afterward to reduce inflammation. This contrast therapy can be especially beneficial for recovery.
Neither option is inherently “better” – they simply offer different therapeutic approaches based on temperature.
Price Comparison and Long-Term Costs
Initial costs for plunge pools typically range from $15,000 to $25,000+ for in-ground installation, while hot tubs generally cost between $3,000 and $15,000.
According to HomeAdvisor, these averages reflect typical installation costs across the U.S., with luxury plunge pool builds sometimes exceeding $40,000, depending on materials and site preparation.
The significant price difference reflects the more extensive construction needed for plunge pools.
Operational Cost Comparison:
- Hot tubs: Higher energy costs ($50-150 monthly) to maintain water temperature
- Plunge pools: Lower energy costs unless heated, but may have higher water treatment expenses
Maintenance requirements also differ. Hot tubs need more frequent chemical balancing and filter cleaning due to their smaller water volume and higher temperatures. Plunge pools require less frequent maintenance but may need more chemicals per treatment.
Lifespan is another consideration. A quality hot tub typically lasts 10-15 years, while a well-built plunge pool can last 25+ years, potentially offering better long-term value despite higher upfront costs.
