How Much Space Do You Need for a Swim Spa in the UK?

Swim spas are the perfect blend of fitness and relaxation, but before you dive in, one big question comes up: “Can I fit a swim spa in my garden?”

The good news is: yes, probably! Even modest gardens in the UK can often accommodate a swim spa, but it depends on the model, access, and planning. Here’s what you need to know.

📏 Typical Swim Spa Dimensions

Hydropool swim spas come in various sizes, but here are some general guidelines:

Model TypeLengthWidthHeight
Small-Size~3.8m~2.3m~1.3m
Mid-Size~4.3m–4.7m~2.3m~1.3m
Large Dual-Zone Spa~5.3m–6m~2.3m~1.3m

💡 Rule of thumb: Allow at least 1 metre of clearance on each side for servicing, installation, and access.

So, for a 5.3m-long spa, you’d ideally need a 7.3m x 4.3m area including access space.

🛠️ Other Key Space Considerations

1. Access for Delivery

Most swim spas are delivered using cranes or dollies. We’ll check whether your property allows direct access or needs specialist lifting.

2. Base/Foundation

You’ll need a flat, reinforced concrete base that can support the weight when filled (often 7,000–10,000 kg). Typically:

  • Depth: 150mm reinforced concrete
  • Size: Slightly larger than the spa’s footprint
3. Power Supply

Your swim spa requires a dedicated power supply, usually 32 or 40 amp, depending on the model. Cables are ideally installed during groundwork.

4. Drainage & Water Supply

While not essential, it’s helpful to have easy access to an outdoor tap and drain for water changes.

🧱 Can I Sink It Into the Ground?

Yes, many clients choose an in-ground or semi-recessed install for a sleeker look. This requires excavation and possibly retaining walls or drainage planning.

We can advise on whether this suits your garden and budget.

🌦️ Do I Need Shelter or Cover?

UK weather can be unpredictable. Many clients install pergolas or enclosed garden rooms for year-round use and protection from debris.

Hydropool swim spas also come with insulated hard covers to maintain water temperature and safety when not in use.
