Looking to invest in a hot tub or swim spa? Our buyers guide for hot tubs and swim spas covers everything you need to know - from choosing the right model to installation, maintenance, and more.
Understanding the Differences: Hot Tubs vs Swim Spas
Hot tubs are primarily designed for relaxation, offering warm water, hydrotherapy jets, and comfortable seating. They're great for unwinding at the end of the day or socialising with friends.
Swim spas, on the other hand, combine the benefits of a hot tub with the functionality of a swimming pool. They include powerful jets that allow you to swim in place, making them ideal for fitness and exercise as well as leisure.
Choosing the Right Size for Your Space
Size matters for both comfort and practical installation. Measure your available space and consider access points for delivery. Hot tubs typically range from 2-person models to larger 8-seaters. Swim spas are much longer, often 4 to 6 metres, and need more room.
Think about how many people will regularly use it, and whether you’ll want space to stretch out or exercise.
Key Features to Look For
Modern hot tubs and swim spas come packed with features. Look out for:
- Adjustable massage jets
- Bluetooth speakers
- Wi-Fi connectivity for remote control
- Multi-colour LED lighting
- Built-in waterfalls
Prioritise features that suit your lifestyle, whether that’s mood lighting for ambience or powerful jets for hydrotherapy.
Energy Efficiency and Running Costs
Running costs can vary significantly depending on insulation, heater quality, and how often you use your tub or spa. Models with high-density foam insulation, efficient covers, and programmable settings can help reduce energy usage.
Always check the estimated monthly running cost provided by the manufacturer, and opt for energy-efficient pumps and heating systems when possible.
Indoor vs Outdoor Installation
Outdoor installations are most common, offering natural ventilation and fewer concerns around drainage or humidity. However, indoor installations are possible and can be ideal for year-round use.
If going indoors, consider proper ventilation, moisture-resistant materials in the room, and access for servicing. Outdoors, you'll need a level base, often concrete or decking, and easy access to power and water.
Water Filtration and Maintenance Needs
Clean water is crucial for a safe and enjoyable experience. Look for systems with multi-stage filtration and ozone or UV sanitising systems. These reduce chemical use and make maintenance easier.
Regular maintenance tasks include checking pH levels, cleaning filters, and replacing water every few months. Choose a model that makes these jobs as simple as possible.
Safety Features to Consider
Especially important if children or elderly users are involved, safety features may include:
- Non-slip surfaces
- Lockable insulated covers
- Accessible steps or handrails
- Emergency shut-off buttons
These additions can help prevent accidents and offer peace of mind.
Delivery and Installation Options
Many suppliers offer delivery and installation as part of the package. Check what’s included: will they position the spa, connect it to electrics, and fill it?
Some installations may require a crane or groundwork, so always confirm what's needed in advance. Professional installation ensures safety and avoids costly mistakes.
Warranty and Aftercare Support
A good warranty is a sign of confidence in the product. Look for at least 5 years on the shell and 1–3 years on parts and labour.
Also, check for aftercare services such as maintenance plans, repair support, and customer helplines. This ongoing support can be invaluable down the line.
Materials and Build Quality
High-quality hot tubs and swim spas are built to last. Look for:
- Durable acrylic shells
- Corrosion-resistant frames (steel or composite)
- UV-resistant cabinet panels
- Well-insulated covers
Investing in quality materials means fewer repairs and a longer lifespan.
Setting a Budget and Comparing Prices
Prices vary widely. Entry-level hot tubs can start around £3,000, while high-end models or swim spas can exceed £20,000. Keep in mind delivery, installation, electrical work, and running costs when budgeting.
Compare like-for-like features across brands, and watch for seasonal sales or showroom discounts.
Where to Buy: Online vs Showroom
Buying online can offer convenience and lower prices, but it comes with risks. You can’t see the product in person or test the jets.
Showrooms allow you to try before you buy and speak with experts. Some even offer “wet tests” so you can experience how the jets feel. For peace of mind, many buyers opt for a showroom with strong reviews and in-person support.
