If you’ve ever been tempted by the thought of a bubbly soak under the stars but balked at the price of a full-built spa, you’re not alone. Inflatable hot tubs have surged in popularity in the UK — and with good reason. They’re cheaper, easier to install, and surprisingly durable. But are they actually worth it?
As your resident value-seeker, I’ve done the research so you don’t have to. Let’s look at the pros, cons, and practicalities of inflatable hot tubs — from pricing and performance to electricity use and brand reliability.
Price: Big Bubbles, Smaller Bills
Traditional hard-shell hot tubs can cost anywhere from £3,000 to £10,000+. That’s a serious investment. Inflatable options, by contrast, start around £250–£800 — which makes them far more accessible for families, renters, or first-time spa owners.
The standout brand in this space is Lay‑Z‑Spa, with popular models like the Miami, Paris, and Helsinki regularly topping Amazon’s bestseller list. You’ll also find solid contenders from CosySpa, Wave Spa, and Intex.
My tip? Look for models that bundle in extras like covers, ground mats, and timers — it can save you £50+ in add-ons.
Features: Surprisingly Well Equipped
Don’t let the word “inflatable” fool you — many of these tubs pack some serious tech. The better models come with:
- Heated air jet massage systems
- Digital control panels with timers
- Freeze Shield™ tech for year-round use
- Integrated filters and chemical dispensers
Some even have LED lights, built-in Bluetooth speakers, and Wi-Fi app control — yes, really. While the bells and whistles are fun, the most important thing is water capacity, heater strength, and build quality.
Garden Size & Setup
Most inflatable hot tubs seat 2–6 people and range from 1.5m to 2m in diameter. For a small patio or modest-sized garden, they’re ideal — just make sure you have:
- A flat, solid base (concrete or decking is best)
- Close access to a power socket (with RCD protection)
- A hose nearby for filling and draining
You’ll also want at least 50cm of clearance around the tub for ease of use and maintenance. If you’re renting or have a small outdoor space, the compact models like the Lay-Z-Spa Bali or Miami are especially practical.
Electricity Usage: What Will It Cost to Run?
Electricity is the big question for many first-time buyers. Inflatable hot tubs typically draw 2kW to 2.5kW while heating. To heat from cold to 40°C takes about 10–12 hours, depending on ambient temperature.
Once warm, maintaining heat will use much less power — especially if you use an insulated cover and run it during off-peak hours. On average, expect around £7–£15 per week in electricity costs if used moderately.
Value tip: Use a smart plug or the built-in timer to preheat during cheaper tariff hours. Some models also feature energy-saving modes.
Best Brands to Trust
Here are the top-rated and most reliable brands on the market right now:
- Lay‑Z‑Spa – UK’s bestselling brand; huge range, great support
- CosySpa – Affordable, no-frills models with quick delivery
- Intex – Known for high build quality and sturdy construction
- Wave Spa – Stylish designs with premium features
Lay-Z-Spa dominates for a reason — they’ve nailed durability, ease of use, and customer service. Their Helsinki and Paris models are particular standouts for quality and value.
Maintenance & Practicality
Inflatable hot tubs are easy to set up and pack away. Most inflate in 5 minutes and fill in 1–2 hours. You’ll need to treat the water with chlorine tablets (most kits include a ChemConnect dispenser), and change filters weekly.
Insulated covers and mats are essential to protect against debris and heat loss. If you look after your tub, it can easily last 2–3 years — and maybe longer.
Verdict: Worth It?
Yes — if you manage your expectations. Inflatable hot tubs aren’t built for wild parties or freezing winters, but they’re brilliant for casual use, muscle recovery, and weekend relaxation.
For under £500, you’re getting a portable spa experience that adds real comfort and enjoyment to your outdoor space — and that’s excellent value in my book.
