Buying a hot tub comes down to three categories: inflatable (€500–800), frame spa (€1,500–2,500), or hardshell outdoor (€3,000–10,000). The right choice depends on your budget, how many people will use it, and whether you want it year-round or just in summer.

Inflatable hot tub (€500–€800)
An inflatable hot tub is the fastest way to have a home spa. Set it up in 30 minutes, and when you’re done with it, drain it and pack it away in a cupboard. The three major brands are Lay-Z-Spa (by Bestway), Intex PureSpa, and MSpa.
All models under €800 use AirJets only: air bubbles rising from the floor. They’re relaxing but not the same as the targeted water jets of a hardshell. The exception: the Lay-Z-Spa Hawaii HydroJet Pro has real water jets at around €800.
Lay-Z-Spa vs Intex: the key differences
| Feature | Lay-Z-Spa Paris | Intex PureSpa Olive Green |
|---|---|---|
| Price | ~€549 | ~€702 |
| People | 4–6 | 4 |

| Jets | 140 AirJets | 120 AirJets |
| LED lights | Yes | No |
| Freeze Shield | Yes | No |
| Warranty | 1 year | 1 year |
The Lay-Z-Spa Paris is cheaper, has more jets, and includes LED lighting. The Intex PureSpa stands out for its olive green design and Fiber-Tech walls, which are slightly more rigid than standard vinyl.

When to choose the HydroJet Pro
If you want real massage action — comparable to a hardshell — the Lay-Z-Spa Hawaii HydroJet Pro is the only inflatable option. Actual water jets that push directed pressure onto your back and shoulders. It costs more and requires slightly more maintenance (rinsing the extra jet filters), but the difference in feel is substantial.

- App control with scheduling
- Freeze Shield for frost use
- Noticeably stronger massage than bubble-only models
- Most expensive inflatable model
- Extra maintenance for jet filters
Frame spa and MSpa (€1,500–€2,500)
A frame spa is technically inflatable but has a rigid metal or plastic frame around it. That makes it more stable, better insulated, and more compact than a fully inflatable model. MSpa and Bestway sell models in this segment for €1,500–€2,500.
The advantage over fully inflatable: better insulation (lower energy bills), a sturdier feel, and often more jets. The downside: harder to store away and significantly more expensive.
Hardshell outdoor hot tub (€3,000–€10,000)
A hardshell outdoor hot tub is made from acrylic or rotomoulded polyethylene with rigid insulation panels on all sides. Water capacity 800–1,800 litres. The big win is the real hydrotherapy jets: 10 to 60 adjustable nozzles targeting the back, shoulders, feet, and legs.
Brands like W’eau, Villeroy & Boch, Hydropool, and Aquavia deliver hardshell models from €3,000 to €20,000. Most models above €5,000 can be paired with a heat pump that halves energy costs compared to an electric heating element.
Hardshell: what does it actually cost per month?
At €0.30 per kWh and a well-insulated hardshell:
| Situation | Daily consumption | Monthly cost |
|---|---|---|
| Summer, cover on | 1.0–1.5 kWh | €9–€14 |
| Winter, cover on | 1.5–3.0 kWh | €14–€27 |
| Summer, no cover | 3.0–5.0 kWh | €27–€45 |
A thermal insulating cover saves €200–€400 per year. Hardshell models include one as standard. For inflatable models, buying a separate thermal cover is strongly recommended — the standard air lid barely insulates.
Energy costs: all types compared
| Type | Daily consumption (standby) | Monthly cost summer | Monthly cost winter |
|---|---|---|---|
| Inflatable without thermal cover | 3–5 kWh | €27–€45 | €54–€90 |
| Inflatable with thermal cover | 1.5–3 kWh | €14–€27 | €27–€54 |
| Frame spa with good insulation | 1.2–2.5 kWh | €11–€23 | €22–€45 |
| Hardshell (full-foam) | 1.0–2.0 kWh | €9–€18 | €18–€36 |
| Hardshell + heat pump | 0.3–0.8 kWh | €3–€7 | €7–€14 |
A pool or hot tub heat pump is the best investment for hardshell owners who use it year-round: the payback period is 2–4 years.
Placement: what you need to arrange
For an inflatable hot tub you only need a flat, solid surface that can hold the weight. A filled 4–6 person inflatable spa weighs 900–1,200 kg. Patio tiles, concrete, and firm ground are fine. Soft lawn will sink.
For a hardshell:
- Base: poured concrete (10 cm) or concrete paving on compacted sand
- Load capacity: minimum 500 kg/m²; a 2×2 m spa filled weighs 2,000–3,000 kg
- Power supply: 230V for models up to 2.5 kW; 400V (3-phase) for larger units — always use a certified electrician
- Drainage: you need a drain connection for emptying
Water chemistry in a hot tub
A hot tub demands more attention to water quality than a swimming pool. At 38–40°C, chlorine degrades faster and bacteria multiply more quickly. Target values: pH 7.2–7.6, free chlorine 3–5 mg/l.
Test after each session. Fully replace the water every 3–4 months.
Which hot tub is right for you?
Choose inflatable if your budget is under €800, you use it seasonally, or you want to try a hot tub before committing. The Lay-Z-Spa Paris (€549) is the best-selling entry model — reliable, energy-efficient with a cover, and spare parts are easy to find.
Choose a frame spa if you’re willing to spend €1,500–€2,500 for better insulation and more stability without the installation requirements of a hardshell.
Choose a hardshell if you want to use it year-round, want real hydrotherapy jets, and expect a lifespan of 15–20 years. The higher purchase price pays back through lower energy bills and more enjoyment.
