Should I buy a Round Spa? (Features, Pros and Cons)

Pros and Cons of Round Spas

Round spas offer a unique blend of style, comfort, and practicality, but they may not be the perfect fit for everyone. Below, we break down the key advantages and drawbacks to help you decide if a round spa is right for you.

Pros:

• Space-Saving Design – A smaller footprint makes round spas a great fit for compact areas.
• Social Seating Arrangement – The circular shape allows for face-to-face interaction, making it great for gatherings.
• Aesthetic Appeal – offers a timeless, elegant look that blends well with any outdoor or indoor setting.
• Easier to Clean – The open seating and lack of bucket seating or seats with deviders found in many square or rectangular spasmaked cleaning easier. However, cleanliness still depends on the building material, filtration, water chemistry, and maintenance habits rather than just shape.
• Affordable Options – Typically less expensive than large, feature-packed square or spas.

Cons:

• Limited Seating Variety – Mostly bench-style seating, with fewer ergonomic options than square or rectangular spas.
• Fewer Customisation Options – They often lack built-in recliners, varied seat heights, or advanced hydrotherapy features like a Neck and Shoulder Seat
• May Not Fit All Spaces – While compact, their shape may not suit narrow or irregular layouts and building near a round shape can add complexity and costs
• Fewer Jet Placement Options – The curved shape may limit targeted jet placement compared to square or rectangular designs
• Less back Support – Round spas lack corner seating, which some users find more supportive.

Round Spa vs. Other Spa Shapes: Which Is Best for You?

When choosing between a round spa and other shapes, consider the following factors:

What’s the running cost of round spas?

Like other spa shapes, the running cost of round spas depends on several factors, including:

• Energy Efficiency – Well-insulated round spas with high-quality covers retain heat better, reducing energy consumption.
• Heating System – The type of heater (electric, gas, or heat pump) impacts overall running costs.
• Pump & Filtration System – Energy-efficient pumps and circulation systems help lower electricity usage.
• Water Volume – Larger round spas require more water and energy to heat, increasing costs.
• Usage Frequency – More frequent use leads to higher electricity and water treatment expenses.
• Local Electricity Rates – Costs vary depending on your region’s energy prices.
• Maintenance & Chemicals – Regular water treatment, filter changes, and general upkeep contribute to ongoing expenses.

In warmer months, a well-insulated spa costs around $30–$50 per month to run. In winter, this can rise to $60–$80, or over $100 if the spa lacks insulation—especially in colder regions.

Electricity rates also impact costs, so it’s worth checking local prices when budgeting.

Using a heat pump can reduce energy use by up to 75%, making your spa much more efficient.

Should I buy a round spa?

Choosing the right spa depends on your priorities. If you want a space-efficient, social-friendly design with a timeless aesthetic, a round spa is a great option. Its open seating layout encourages conversation and relaxation.

However, if you prefer lounge seating, targeted jet placement, or a spa that fits neatly into a corner, a square or rectangular model may be a better fit.

These shapes often offer more structured seating and customisation options. When it comes to features and running costs, round spas are similar to other shapes—the key differences lie in seating style and aesthetics.

Bottom line? If you love the classic, open-concept feel of a round spa or are drawn to a cedar hot tub but want more comfort and durability, it’s a great choice.

But if ergonomic seating and jet variety are your priorities, exploring other shapes might be worthwhile.

Where Can You Put a Round Spa?

A round spa can be placed in various locations, depending on your space, style, and installation preferences. Here are some popular options to consider:

• Outdoor Decking – Easy to access and enhances your outdoor space.
• Patio or Garden Areas – Blends beautifully with natural surroundings.
• In-Ground Installation – Provides a seamless, high-end look.
• Indoor Spaces – Works well in ventilated areas with proper moisture control.
