Since it makes use outside air, the temperature may affect that of the water. The colder it is outside, the more noticeable the decrease in the water’s temperature. In worse cases, it is not a sudden drop but more of a gradual process as the bubble jets continue to run. We have yet to see an inflatable spa with heated bubble jets. Once that becomes available, you’ll definitely find it here first.
A built-in hot tub is really heavy – and it is built-in. You cannot carry it around. It is more or less a permanent fixture in your home. If you want to move it, you will have to spend several days just disassembling it. You will have to hire an electrician and plumber to help you with the more technical aspects involved in installing or disassembling a traditional hot tub.
Lay Z Spa, now also known as SaluSpa, are categorized into 3 groups: AirJet, HydroJet, and HydroJet Pro. The AirJet series is their most basic and most affordable models. They have standard water filtration installed and air bubbles for massage jets. The Hydrojet and HydroJet Pro are their high-end models with additional water treatment system and additional massage jet type as well.
The soft but non flimsiness of inflatable hot tubs may be a hit or miss depending on the consumer. But a lot of people who have sat in $6000+ hot tubs have actually preferred the softer feel of inflatable tubs to the concrete, plastic and other mashups of portable hot tubs. Inflatable hot tubs are soft but firm, and really provide a relaxing feel compared to portable hot tubs. This is of course based on individual tastes, so take that with a grain of salt. Inflatable hot tubs also inflate and deflate pretty quickly, so that is less time waiting around for it to reach max capacity so you can start filling it with water. But portable hot tubs don’t have this waiting period at all, and if you’re the type that is in a rush that extra time it takes to inflate can really make a difference.
The salt cell used for saltwater hot tubs is a titanium coated electrolytic cell, which will eventually lose enough of its coating to stop producing enough chlorine. Spa salt cells usually last 2-5 years, depending on the model. At that point, you can replace just the cell (not the power supply). Keeping your cell clean (some models are self-cleaning), and not using it for cold spa water (below 60° F), are key to a long cell life.
After reviewing several portable hot tubs, we decided the Lay-Z Spa Miami was the one we would purchase. We purchased the 2nd week in February and received within a week of ordering. Setup was simple and straight forward. We maintain the water quality every week by taking a sample to our local pool supply store. I wouldn't recommend this for children as the water temp max is 104 degrees. But for a good 20 minute soak, it does the job. (wife having chronic muscle spasms). If the hot tub lasts us a year, we will definitely purchase another one. Great price for the money spent. And a better deal then the hard shells. The pics and video were taken recently.
