How Much Does a Hot Tub Cost in the UK? (2026 Guide)
Adding a hot tub to your garden is something more and more people in the UK are starting to think about, especially when they want a quiet space to relax and unwind at home. Whether it’s after a long day at work, spending time with family, or simply improving the look and feel of an outdoor space, a hot tub can completely change how you enjoy your garden. But before making a decision, the first question almost everyone asks is the same: how much does a hot tub actually cost in the UK?
The answer isn’t always straightforward, because prices vary depending on the type of hot tub, its size, the materials used, and the heating system. Some people go for modern electric spas, while others prefer a more traditional option like a wood fired hot tub, which uses firewood to heat the water naturally.
In this 2026 guide, we’ll break down the real cost of buying and running a hot tub in the UK, what affects the price, and what you can expect depending on the type you choose.
Average Cost of a Hot Tub in the UK
Hot tubs in the UK come in a wide range of prices, from budget-friendly inflatable models to high-end luxury spas. On average, you can expect to spend anywhere between £300 and £15,000+.
Here’s a simple breakdown:
- Inflatable hot tubs: £300 – £800
- Entry-level hard shell hot tubs: £2,500 – £5,000
- Mid-range spa hot tubs: £5,000 – £9,000
- Premium luxury hot tubs: £9,000 – £15,000+
- Wood fired hot tubs: £3,000 – £8,000
While electric spas are more common in urban homes, many people are now moving towards wood fired hot tubs because they offer a more natural experience and often cost less to run in the long term.
Why Hot Tub Prices Vary So Much
If you’ve started researching hot tubs, you’ll quickly notice that prices can differ a lot. This is because several factors influence the final cost.
1. Size of the Hot Tub
The size is one of the biggest price factors. A small model will always be cheaper than a large family-sized spa.
For example:
- A wood fired hot tub 2-person model is compact, simple, and usually more affordable.
- A wood fired hot tub 4-person option is larger and designed for families or small groups.
- Bigger models for 6–8 people naturally cost more due to extra materials and water capacity.
2. Type of Heating System
The heating system plays a huge role in both cost and running expenses.
Electric hot tubs use built-in heaters and pumps, which require constant electricity. On the other hand, a wood fire heated hot tub uses a simple but effective system that burns firewood to heat the water.
A wood fired hot tub heater is usually made from stainless steel and designed to transfer heat quickly and efficiently. This traditional method is one of the reasons many homeowners prefer hot tub wood fired systems, especially in rural or off-grid areas.
3. Materials and Build Quality
The materials used in a hot tub also affect its price and durability.
A wooden wood fired hot tub is a popular choice because it blends naturally into outdoor spaces and offers better insulation. High-quality timber or thermally treated wood increases durability and improves heat retention.
Cheaper models may use lower-grade materials, while premium options focus on long-term performance and weather resistance.
4. Features and Add-ons
Modern hot tubs often come with extra features that increase the overall price, such as:
- LED lighting
- Hydro massage jets
- Insulated covers
- Built-in filtration systems
- Steps and seating upgrades
A basic wood fire hot tub usually focuses on heating and soaking, while luxury models add more comfort features.
How Much Do Wood Fired Hot Tubs Cost in the UK?
A wood fired hot tub UK typically costs between £3,000 and £8,000, depending on size, design, and heater quality.
These tubs have become very popular because they offer a more natural outdoor experience. Instead of relying on electricity, they use firewood to heat the water, making them both simple and cost-effective.
Wood Fired Hot Tub 2 Person
A wood fired hot tub 2-person model is ideal for couples or small spaces. It heats faster, uses less water, and is usually the cheapest option.
Price range: £2,800 – £4,500
Wood Fired Hot Tub 4 Person
A wood fired hot tub 4-person model is better for families or small gatherings. It offers more space while still being efficient to heat.
Price range: £3,500 – £6,500
Larger Wood Fired Hot Tubs
Larger models designed for 6–8 people are perfect for social use or holiday rentals.
Price range: £5,000 – £8,000+
Running Costs of a Hot Tub in the UK
Buying a hot tub is one thing, but running costs are just as important.
Electric hot tubs can cost around £30 to £80 per month in electricity, depending on usage and weather conditions.
In comparison, a wood fired hot tub runs on firewood, which is often more affordable. On average, each use may cost around £10 to £25, depending on how much wood is used and how quickly you want to heat the water.
This is one of the main reasons many people choose wood fired hot tubs over electric ones.
Installation Costs
Installation costs vary depending on the setup and location.
For electric hot tubs, you may need:
- Electrical wiring
- Professional installation
- Ground preparation
For a hot tub wood fired system, installation is usually simpler. Most models only need:
- A flat, stable surface (patio or deck)
- Water supply for filling
- Proper ventilation space for the heater
This simplicity often reduces installation costs significantly.
Why People Are Choosing Wood Fired Hot Tubs
