Maybe the best benefit of a saltwater hot tub is that you no longer need to store bromine or chlorine tablets. You should still shock the spa, so keep a granular oxidizer on hand, but you can use chlorine-free MPS if you prefer. Spa salt systems make their own chlorine, so it’s still a chlorinated spa. However, the chlorine is created naturally, without binders or additives. It’s pure chlorine.
A water test kit makes testing your water easy. If your inflatable hot tub does not come with such a kit, you can easily find it at any store that carries pool and spa supplies. Once you have tested the water, adjust it using the necessary chemicals. A good pH range for a portable hot tub is between 7.4 and 7.6. A pH that is too low may damage your hot tub’s vinyl and thus damage the tub.
This Coleman hot tub has a bright green outer layer with a white inner lining. It’s 77 inches in diameter and can seat 4-6 people although it is probably more comfortable with only 4. It can be set up in the garden or in the garage or basement wherever you want to place it as long as it’s a flat surface. All you need is the ability to plug it into an electrical outlet and be able to fill it with water and have a drain within reach when you have to empty it.
Similar to Bestway’s Lay-Z Inflatable Hot Tub, this version also benefits from fabric coated materials and a pool cover with an aluminum foal coating to keep water extra warm at all times. Not only that but it also features a Lay-Z Massage system, a rapid heating system, and an integrated water filtration feature to keep things nice and clean. Furthermore, the tub features a mosaic print pool liner with a cushioned floor and a convenient drain valve.
This Coleman inflatable hot tub as 120 bubble jets installed at the bottom. They are designed to suck in air from the outside and blow through the water. This means turning on the bubble jets can lower the water’s temperature. We advise to heat up the water several degrees higher than your preference before taking a dip to address this shortcoming.
One of the common gripes about these spa’s is the fact that when you use the bubble massage system you can’t use the heater at the same time. The bubbles have a 30 minute auto shut off and in that time the temperature can drop a few degrees. The bubbles going through the water can make it feel a bit cooler too. To be fair this is an issue with most portable hot tubs with bubble jets. It’s easy to switch the heater back on as soon as the bubbles are finished but the temperature only rises a few degrees an hour.
They don’t usually use real water jets, but instead use fans to “blow” the air around (also because of the 120 volt outlet), which causes them to cool down much faster than a regular hot tub. This cooling effect is only made worse by the fact that the materials they are made from lose heat much faster than the materials used on a regular hot tub. All in all, you aren’t likely to get more than 15 minutes to a half an hour of good heat out of an inflatable hot tub.
