Buying guide for portable and inflatable spas

Types & styles of portable spas

Explore round and square portable spa pools in NZ with sizes large enough to fit up to eight people:

Round spas are social by design. Everyone faces inward, making them great for chatting and sharing drinks. They also tend to fit more comfortably into smaller decks and patios.

Square spas maximise usable internal space, giving each person a bit more personal room. They suit more modern outdoor setups and are a good choice if you prefer stretching out over sitting shoulder-to-shoulder.

These spas offer various relaxing features for comfort and convenience: some focus on gentle air bubbles, while others add HydroJets, adjustable massage settings, app control, or integrated water care systems. Select from rigid portable spas or soft inflatable spas, depending on your budget and aesthetic preferences.

Key features & comfort of inflatable spas

Most inflatable spas use AirJets to deliver a gentle, all-over massage designed for relaxation. Higher-spec, rigid models add HydroJets, which can deliver a stronger flow for a firmer feel.

Digital panels let you adjust the temperature, switch jets on or off, and set timers without leaving the spa. Common extras like insulated covers, built-in filtration, padded bases, and cup holders are designed to make day-to-day use comfortable and low-effort.

How to install and care for your inflatable spa

Portable spas are designed for easy setup without specialist tools:

Inflatable spas: Connect the pump to a power outlet and attach it to the pool to inflate it.

Rigid spas: Assemble the spa’s walls. If the spa has a liner, zip it on for added protection. Attach the pump, which should be connected to a power outlet.

Once your spa is ready, you can fill it with water using a garden hose. Heat the spa with the buttons on the pump or the WiFi control app, depending on the model.

Regularly cleaning the filter and maintaining balanced chlorine levels helps keep the water clear and comfortable. Using the insulated cover when the spa isn’t in use helps retain heat and keeps debris out. Placing the spa on a flat, supportive surface helps reduce wear. If it won’t be used for a while, drain, deflate, and store the spa to keep it in the best condition.

Frequently asked questions

How long does it take to pump up an inflatable spa?

Most portable spas fully inflate in 5-10 minutes.

How many people can an inflatable spa fit?

Depending on the model, portable spas typically seat 2 to 6 people, with larger models seating up to 8.

Do inflatable spas require electricity?

Yes. Inflatable spas use electricity to power the heater, pump, filtration system, and massage jets.

How often should the water in an inflatable spa be changed?

Without correct chemical treatment, the water should be changed every three days. With proper chemical treatment and filtration, the water can be used much longer, depending on how frequently you use the spa. Using a pool cover and showering before entering the spa helps keep the water cleaner for longer.

Can inflatable spas be used outdoors year-round?

Many inflatable hot tubs are designed for year-round use and include automatic heating to prevent internal components from freezing during winter.

Are inflatable spas energy-efficient?

Modern blow-up spa pools feature insulated walls, covers, and timer-controlled heating systems to help reduce heat loss and running costs.
