If you are trying to decide between two equal inflatable hot tubs of different sizes, choose the smaller one. The smaller the spa, the more flexibility you have in selecting a location to set it up. Most of the tubs hold around 250 gallons, which can weigh up to 2700 pounds. This is a lot of weight and not all decks can support this. The Bestway SaluSpa Siena only requires 135 gallons of water, which weighs around 1200 pounds. Because the Siena is smaller than its competition, it is also the most convenient inflatable hot tub. The transportation and storage is also much easier. It can be set up and tore down in less than half an hour. In addition, cleaning is easier. It heats up quicker too. Basically, anything you need to do with this tub will be easier than with any other tub on the market.

Despite its smaller size, the intelligent design makes the tub very functional. It is long enough that two people can comfortably sit on either side of the tub without being cramped. It is also wide enough that a couple can lay next to each other in the same direction. The Siena comes with a tray that stretches across the center, providing a nice tabletop. For people that are not confident in being submerged in water it has two sturdy handles. These handles make the Siena the best inflatable hot tub for elderly and injured.


The tub basin is built of quality TriTech 3-ply material. The material has a polyester core encased in a layer of PVC on each side. Polyester provides strength and resistance to tearing. PVC creates a barrier that is airproof, waterproof and puncture proof. You can sit on the edges of the SaluSpa Siena and hardly notice any change in shape. One of the main reasons that the walls remain sturdy is because of the I-Beam technology. The tub is designed so that the inner walls are connected to the outer walls with strong fibers that prevent the walls from expanding outward when air pressure increases. Bestway takes this internal skeleton a step further by creating internal support structures that run horizontal as well as vertical. These internal reinforcements distribute air pressure evenly across the tub walls.


The Bestway SaluSpa Siena is 98 inches long, 59 inches wide, and 26 inches deep when it is inflated. It holds 135 gallons, which is half the water that most of the other tubs hold. Because it is also half the weight of most inflatable spas, weighing in at 1205 lbs, it is one of the only tubs that you could potentially get away with using inside or on a deck.

The Bestway SaluSpa Siena uses a 280 gal/hr heat pump that generates roughly 1320 watts of power. Siena heats up faster than any other inflatable hot tub we have tested. The heat pump is rated to increase water at a rate of 4° F/hr, which is also the highest rating on the market. The SaluSpa Siena is capable of maintaining its max water temperature at temperatures well below freezing.

Siena uses air jets instead of hydrojets. An air jet is a tube that runs along the bottom edge of the floor and has 127 pinholes in it. The air pump pushes air through the tube, which escapes through the pinholes and rises to the surface in the form of countless tiny bubbles. The rising bubbles create a soothing spa experience. The bubbles also cloud the water, adding an extra element of privacy.


The SaluSpa Siena takes a single person less than 10 minutes to completely set up. Since the tub basin is smaller and lighter weight, it is easier to move parts around. Everything you need to enjoy your first soak is included with the spa. All you need to do is position the tub basin on the ground mat. Next, you inflate the tub basin using the air pump inside the pump unit. It takes 5 minutes to inflate the tub. Then you connect the heat pump unit to the tub and fill it with water. Finally, turn on the pump and wait for your water to warm up.


The Bestway SaluSpa Siena is the best inflatable hot tub for a couple. Even though it is smaller than a round spa, the elongated design actually provides more room to stretch your legs. Smaller hot tubs are easier to setup, maintain, and quicker to warm up. It is made with high quality and, because of its smaller volume, it outperforms the larger inflatable hot tubs in almost all categories. In addition, it is the best inflatable hot tub for elderly people because the handle locations make it easier to enter and exit the tub. The table is a great feature for everybody as well. The SaluSpa Siena is the best inflatable hot tub on the market.
