      Check it on Amazon

      What we think

      The Intex PureSpa Plus 4 Person Inflatable Hot Tub is especially enjoyed by families wanting an easily maintainable spa at a great price.

      This inflatable hot tub comes out of the box with some great features like the ambient LED light, a heat retaining lockable cover, a built-in hard water treatment system and to top it off of course the amazing 140 bubble jets. The installation procedure is very easy, the Intex PureSpa Plus can be setup in about twenty minutes!

      The only drawback of this tub that we found is probably that it can take up to one day to reach its maximum temperature, and in order to do this the outdoor temperature must be a minimum of 50 degrees Fahrenheit.

      However, the heat is well retained once the water has reached the desired temperature.

      In conclusion, we honestly can’t do anything but recommend this sturdy inflatable hot tub, it’s absolutely worth the money.

    5. Common Questions

      • Where can I find the manual?

      • You can download a PDF version of the Intex Purespa Plus 4 Person user manual here.

      • Where can I order replacement parts?

      • You can order replacement parts (filters and pumps) for your 4 person Intex PureSpa Plus hot tub through Amazon.

      • Can I place the hot tub directly on the grass?

      • Yes, but you must make sure that the surface is flat and leveled.

      • Can the hot tub be placed on a wooden deck?

      • Yes that is possible, but you should have a proper support or padding underneath.

        The PureSpa 4 person hot tub has a filled weight of about 2,000 pounds, so check whether your wooden deck can support that weight plus the combined weight of four adults inside the tub.

      • Is the power source on this tub 110V or 220V?

      • It is 110V, a standard 3 prong plug is used (a built-in GFCI plug).

      • Can I use the PureSpa Plus inside?

      • Setting up the hot tub inside is not recommended due to the overall weight of a filled hot tub, the high humidity that comes off and the risk of mold.

        Should you however still decide to setup the hot tub indoors, keep the room well vented and install it on a sturdy, levelled foundation that is able to support the weight.

        Some people even use a dehumidifier to lower the humidity when they use their tub inside.

      • Can you leave the cover on the hot tub with the heater on?

      • Yes you can do that, just take the lid off to clean it or go in.

      • How does it take for the PureSpa Plus to heat up?

      • The spa heats up at about 4 degrees per hour at 70°F to 80°F ambient air temperature, up to a maximum temperature of 104°F.

      • Can I use this tub as a cold pool as well?

      • You can use it as a cold pool, the heater does not need to run for the jets to work.

      • Can the speed of the bubble jets be adjusted?

      • No, that can not be changed, the massage bubble jets have one fixed speed.

      • The type of filters used in the PureSpa Plus 4 Person tub are the Intex PureSpa Type S1 Pool Filter Cartridges, which are widely available.

        Most people need to replace the filter every 2 to 4 weeks, depending on usage. Two filter cartridges are already included with the initial purchase.

      • How do I clean this hot tub?

      • You clean it in the same way you would clean a pool – you use a net to scoop out the big debris and add the proper chemicals to keep the tub in a sanitary condition. You could also use a hot tub vacuum or a hand brush to scrub the sides.

      • Can the spa be used during the winter?

      • No, the heater won’t keep up and you could damage the hot tub. The ambient temperature needs to be at least 40°F to properly run the hot tub.
