Spa Vs. Hot Tub: What’s the Difference?

When it comes to relaxation and hydrotherapy at home, the terms spa and hot tub are often used interchangeably. But while they share similarities, there are key differences, especially when you consider the quality, materials, and customisation available in today’s premium spa designs. 

Defining the Basics:

A hot tub typically refers to a portable, self-contained unit made from acrylic or rotomolded plastic. It includes built-in plumbing, electrical, and heating systems and is often used in domestic environments for social soaking and relaxation.

Pros of hot tubs:

• Affordable: Typically lower in upfront cost than spas. 

• Portable: Many models are freestanding and can be moved or relocated

• Quick to Install: Minimal construction work required. 

Cons of hot tubs:

• Limited Lifespan: Materials like plastic or acrylic can wear down over time, especially when exposed to the elements. 

• Aesthetic Limitations: Often bulkier and less visually refined. 

• Fewer Customisation options: Most models offer limited control over design and layout. 

• Unsuitable for Commercial Use: In many cases, hot tubs must be drained and refilled between each bather, resulting in high water usage, increased labour and additional cost for heating and chemicals.

A spa can refer to both portable units and custom-built installations, but in this context, we’re talking about bespoke, high-end spas – permanent features designed with both form and function in mind. 

High-end spas distinguish themselves through craftsmanship, aesthetics, and versatility. Rather than plastic shells, these spas are often constructed using GRP (glass reinforced plastic) and finished with hand-laid mosaic tiles, providing a sleek, modern look that also offers durability and longevity. 

Advantages of Premium Spas:

• Superior Durability: GRP is incredibly strong and long-lasting, especially compared to plastic hot tubs. 

• Elegant Design: Mosaic tiles allow for stunning, customisable finishes that can blend into any outdoor or indoor space. 

• Tailored Comfort: Options for jet placement, seating arrangements, and temperature control mean you get a hydrotherapy experience made just for you. 

• Permanent Installations: Unlike hot tubs, a tiled spa becomes a lasting feature of your home, garden or business place. 

• Commercial Ready: With the ability to integrate commercial grade filtration systems, these spas are perfectly suited for hotels, holiday parks, health clubs and spa days etc. 

Considerations:

• Higher initial investment: But the long-term value, lower maintenance needs, and increased home appeal often outweigh the cost. 

• Professional installation required: But this also means it’s custom-fit to your exact specifications. 

These spas are built with both in-ground and above-ground options, making them suitable for a variety of landscapes, whether you’re integrating one into an existing pool area or making it the centrepiece of a new garden oasis. 

Jets, Heat, and Hydrotherapy

Premium spas come equipped with powerful hydrotherapy jets that can be adjusted to target different muscle groups. Whether you’re seeking relief after a workout or simply a moment of calm, the combination of custom jet positioning and ergonomic seating delivers a therapeutic soak every time. 

Temperature control is another key feature. Unlike basic hot tubs that may take longer to heat or struggle to maintain warmth in colder weather, these spas are designed for efficient heating and consistent temperature maintenance. You can enjoy a comfortably warm soak year-round, even in colder climates. 

Designed for Lifestyle and Longevity

High-end spas are more than just a product – they’re a permanent fixture in your lifestyle. With bespoke design options, including lighting, seating layouts, and control systems, each spa can be tailored to suit your taste and needs. The use of premium materials and finishes ensures that your spa remains a focal point of relaxation for years to come. 

So, Which One’s Right for You?

If you’re after a plug-and-play solution that’s easy to move and install, a standard hot tub may suit your needs. But if you’re looking for a long-lasting, visually stunning spa that offers a superior hydrotherapy experience and flexible installation options, a tiled GRP spa is the clear choice.
