How long does it take to heat up?

The heater raises water roughly 1 to 2°F per hour, so from cold tap water to 104°F can take a day or more. Starting with warmer water and keeping the cover on speeds it up.

Can it stay outside in winter?

Intex builds it from 3-ply laminated PVC for all-season use, but the heater loses ground in cold air and the vinyl stiffens. Most owners drain and store it when temperatures drop near freezing.

How many people fit comfortably?

It seats four, but the round 57-inch interior is snug with four adults. Two or three people have room to stretch out.

What comes in the box?

Two filter cartridges, a thermal ground cloth, an inflation hose, a carry bag, a floating chlorine dispenser and a test strip. The LED lights need 3 AAA batteries, sold separately.

Does it need special wiring?

It runs on a standard 110-volt household outlet. The heater and jets draw significant current, so use a dedicated GFCI outlet and avoid extension cords.

How often do I change the water and filters?

Intex recommends fresh water every few weeks with regular chemical checks. Rinse the cartridges weekly and replace them when they stop clearing the water.
