Introduction
If you are shopping for a home spa, you may notice people use the terms “hot tub,” “Jacuzzi” and “spa” interchangeably. While they all involve soaking in warm water with massaging jets, they have distinct meanings. Understanding these differences will help you choose the right product for your needs and budget.
What is a hot tub?
A hot tub is a self-contained unit that heats and circulates water through powerful jets to provide hydrotherapy. Most modern hot tubs are pre‑assembled with an insulated shell, integrated heater, pump and filtration system. They are portable and can sit above ground on a sturdy base. Hot tubs come in many sizes and styles, from compact two‑person models to large family tubs. Because they are all‑in‑one systems, hot tubs are relatively easy to install and can be used outdoors or indoors.
What is a Jacuzzi?
Jacuzzi is not a generic term – it is a brand name. The Jacuzzi brothers invented a therapeutic whirlpool bath in the 1950s, and their company went on to produce jetted bathtubs and high‑end hot tubs. Over time, the name became synonymous with any spa bath, in the same way that people often call vacuum cleaners “Hoovers”. When you see the name Jacuzzi, you are looking at a branded hot tub made by the Jacuzzi group. These models generally use quality materials and powerful jets, but they function just like other premium hot tubs.
What is a spa?
The term “spa” can mean a few different things. In the pool industry, a spa is a small pool or tub designed for relaxation and hydrotherapy. Many spas are built in‑ground or connected to a swimming pool and use jetted seating similar to a hot tub. Because they are usually custom built with masonry or concrete, spas are not portable and require professional installation. In everyday language, “spa” may also refer to wellness centres or natural mineral springs; however, when comparing hot tubs and Jacuzzis, a spa typically refers to a built‑in jetted pool.
Key differences
- Brand vs product: A hot tub is a generic product category, while Jacuzzi is a trademarked brand. All Jacuzzis are hot tubs, but not all hot tubs are Jacuzzis.
- Portability: Hot tubs are self‑contained and portable; spas are usually permanent in‑ground structures that form part of a pool or patio.
- Installation: Hot tubs only need a solid base and electrical connection, whereas spas require construction work and often planning permission.
- Cost: Portable hot tubs (including branded Jacuzzis) typically cost less to install than custom‑built spas, though high‑end models can still be expensive.
- Uses: Both hot tubs and spas provide hydrotherapy and relaxation, but spas may also be used as plunge pools or attached to larger pools for exercise.
Which one should you choose?
If you want the flexibility of a stand‑alone unit that can be installed quickly, a hot tub is the best choice. Branded options like Jacuzzis offer premium features and high build quality, while many other manufacturers produce efficient models that run on a budget. A custom spa is ideal if you are undertaking major garden landscaping, want a built‑in look or need a jetted pool connected to your swimming pool.
Ultimately, the right option depends on your space, budget and how you plan to use your tub. Whichever you choose, be sure to invest in a well‑insulated model, keep up with regular maintenance and follow the manufacturer’s guidelines for safety and water care.
