How long does it take to heat up?

Expect many hours to reach a warm soak from cold tap water; Intex rates the heater at about 1 to 2 degrees Fahrenheit per hour. A fitted insulated cover and ground cloth help hold the heat.

Can it stay outside in winter?

It can run in cool weather, but the inflatable walls and cover lose heat fast, so heating costs rise and the water may not hold temperature. Many owners drain and store it for the coldest months.

How many people fit comfortably?

Intex rates it for four adults. In practice two to three adults sit comfortably with room to stretch; four is tight.

What comes in the box?

The tub, a control panel with heater and bubble blower, an insulated cover, a thermal ground cloth, two filter cartridges, an inflation hose, a carry bag, a floating chlorine dispenser and a test strip.

Does it need special wiring?

It runs on a standard household outlet, but the heater and blower draw significant current. Use a dedicated circuit and check that your outlet is GFCI-protected.

How often do I change the water and filters?

Intex recommends changing the water every few weeks to a month with regular use, and rinsing or replacing the two filter cartridges about every two weeks.
