Sustainable, insulation-focused design is at the heart of the Osaka hot tub’s appeal. Besides the family-size appeal of the Swift, comfortably accommodating up to 6 people, the real selling point of this jacuzzi is its eco-friendly stance. The foam core design of the Osaka tub is 50% more efficient than its inflatable counterparts - insulated to retain heat and reduce your electrical costs in turn. Not only does the core contribute to reducing electricity consumption, but the Osaka hot tub is our only spa that comes equipped with an inflatable heat-retaining cover and dressed in distressed leather. Equipped with a 120 massaging air bubble system for ultimate rejuvenation, our automated heating systems, the luxury spa experience has never been so convenient, nor so affordable.

How long is the warranty on the Osaka tub?
The Osaka hot tub has a 6 month warranty on liners (the body of the spa) and a 1 year warranty for the heating unit that controls the temperature and water flow.
What extras do I need to buy for my Osaka?
The grey milan tub arrives with a heater unit, cover, filter, filter housing, inflation hose and ground sheet, which is everything you need to set up and inflate your hot tub. However, we advise purchasing our Pool and Spa starter kit containing all the chemicals you need to keep your hot tub water clean and safe. For added protection and insulation, we recommend using a bubble mat liner and inflatable cover. The Osaka needs a 6 person cover.
How much will it cost to run my Osaka hot tub?
The average cost of powering all of our heater units for 1 hour is $0.27

Our Rigid Foam tubs take approximately 27 hours to get to maximum temperature of 104 F - meaning that the total cost to reach maximum temperature is $7.29

The average cost of bubble function is $0.39 per hour. However, the bubble function cannot be run simultaneously with the heater function, therefore we recommend sporadic use in order to retain optimal water temperature.

The cost of maintaining heat is approximately the same as the cost to heat up ($0.27 per hour), but this does differ depending on the ambient temperature. Where you are located will impact water temperature, if you frequently experience low temperatures, we would recommend insulating your tub sufficiently with our Inflatable Hot Tub Covers and Bubble Mat Liners. However, our Rigid Foam hot tubs are supplied with greater insulation conducive to heat retention, meaning less heat-up time, and lower costs in turn.

*Please note, these calculation are based around the average US cost of cents per kWh. These prices will vary depending on your electricity provider. Please check for an updated price with your electrical supply company if you need to calculate more detailed usage costs.
Can I use my Osaka tub all year round?
Yes! As Wave inflatable hot tubs are portable, you can definitely use your spa all year round. Our soft hot tubs can sit comfotably outdoors in most weather conditions. However, to ensure your liner has a longer life span, we recommend moving your hot tub indoors when temperatures drop lower than 40°F. Our portable hot tubs are incredibly easy to set up, inflating in just 5 minutes.
When will my payment be taken?
As we are a UK based company, your payment will be taken at the point of purchase instead of the point of shipment. This is the customary procedure in British business sales, helping us get your products to you even faster!
Which filters will I need to buy with the Osaka tub?
As you are purchasing the Wave Tub post-2020, the filters you need will be listed as the '2020 onwards filters'. Please note that these are not just an advanced version that we recommend, but a different size entirely. The pre 2020 filters, though cheaper, will not be compatible with your tub.
