How long does it take to heat up?

Expect roughly a day or more from cold tap water, depending on starting temperature and outdoor conditions. The insulated cover helps, but heating is slow compared with rigid tubs.

Can it be used in winter?

It can run in cool weather, but heat loss is significant and the heater may not keep up in freezing conditions. Many owners insulate the base or use it mainly in milder months.

Does it need a special electrical outlet?

No. It runs on a standard 110-120V household outlet, though it should be on a dedicated circuit to avoid tripping breakers.

How many people fit comfortably?

It is rated for four, but adults fit more comfortably as a two- or three-person tub. The round 77-inch diameter leaves limited legroom when full.

What comes in the box?

The tub, insulated cover, inflation hose, filter cartridges, ground cloth, wireless control panel and a carry bag are typically included.

How often do I need to change the water?

Most owners change the water every few weeks to a month, depending on use and chemical upkeep. The filter cartridge needs rinsing regularly and replacing periodically.
