Lay-Z-Spa SienaWhen we were greeted with the Lay-Z-Spa Siena Airjet inflatable hot tub, we didn’t know what to expect. Inflatable hot tubs are something we take seriously here, and we wanted to see how it measured up to some of the tubs that have gone before it. We particularly liked the standout features on the Monaco – a light up version – and the ample space found in the Paris model.

So how does the Siena compare when we start to test it against the same high standards, we held the others accountable to? There’s only one way to find out… Join us as we indulge ourselves in the Lay-Z-Spa Siena review and get a well-rounded idea of the scope this inflatable hot tub has.

Should you Buy an Inflatable Hot Tub?

There are plenty of reasons why buying an inflatable hot tub could be right for you. If you have the kind of lifestyle where you spend a lot of time at home, then this product can improve your overall quality of life. Similarly, hot tubs are reported to have numerous health benefits to the user. Be it Fibromyalgia or autism, we have heard reports from reviewers everywhere about the health benefits of bathing in your very own hot tub.

Why buy an inflatable hot tub instead of a regular hot tub? It’s a fairly straight forward idea. The upheaval, expense, and potential refurbishment needed to have a home hot tub fitted goes beyond the ‘big purchase’ list. It is a full-on home renovation to install one – and they come with a mammoth price tag to match. If you can afford it, then go ahead. If you want to save yourself money or even if you think you might be moving home soon, an inflatable home hot tub is the obvious answer.

With the inflatable model, you get all the benefits with none of the drawbacks. It’s a heavy, durable material that can be used indoors or outdoors. Better yet, it is just as bubbly, just as hot, and just as attractive in aesthetic appeal as any other in-built hot tub. All-in-all, there’s no reason to opt for an in-built hot tub other than to increase the value of your home. There are a lot of people out there that don’t think this is worth the stress.

Ultimately, the choice is yours. An inflatable home hot tub comes with temperatures you can control, digital panels, full safety precautions, and all the bubbles you need. If you happen to be in the market for a great home addition that you can take with you when you leave? This is the ideal answer for a comfortable home improvement.

The Benefits of an inflatable hot tub at home:

  • It’s portable and can be transferred if you move home.
  • Soaking in a hot tub has proven health benefits
  • It takes less electricity to run a hot tub than you would think
  • They range in size from 2 person to 10 person
  • They are easy to keep clean when bought from Lay-Z-Spa
  • It’s a tough, durable, long-lived hot tub that won’t let you down
  • They can be used indoors or outdoors
  • They are simple to set up

The Drawbacks of an inflatable hot tub at home:

  • They take a lot of water to fill
  • They can be too heavy for your flooring
  • If used outside you will need a waterproof extension cable (an outdoor-friendly one)

What’s in the Box?

Now that we have examined what it is and what it looks like, let’s summarise exactly what you get in the box when you buy a Siena Airjet inflatable hot tub for your home.

The Airjet Siena Liner

This outer/inner liner is made of that extra tough and durable TriTech fabric. The three tough layers keep it tear resistant and waterproof all the way around. The outer liner is a blue grey colour and the inner one is a very light blue. This off-white colouring keeps any dirt disguised until you can top up the water.

Filter Cartridges

The Siena two person 127 massage airjet inflatable home hot tub comes with filter cartridges that will catch dirt and debris particles. This is placed inside the pump, which allows the air to push water through the filters and catch any dirt.

The 127 Airjet Pump

The 127 airjet bubble streams create a massaging effect and are spread throughout the entire tub. The air is drawn in through the top, then pushed out through the streams, allowing for a complete spa experience for all involved. This attaches to the side of the hot tub and pushes air through the streams to give you a great hot tub experience.

The Chem Connect System

The Chem Connect floating chemical dispersal system. You should buy chemicals for this separately, but its patented design lets those chemicals be dispersed evenly throughout the water, whether you are in it or not. This is Lay-Z-Spa’s very own design and is patented to them, so it goes to show how much they invest in research and development to continuously bring us new products.

The Digital Control System

The timer and heating controls are on top of the airjet pump. Although it is one unit and will arrive already put together, we find it best to point out where the controls are. Many seem to think they are inside the pool itself, but the digital control panel for an inflatable home hot tub is actually located on top of the air pump.

Inflatable Hot Tub Lid – Siena Model

The lid for an inflatable hot tub by Lay-Z-Spa is usually in two parts. First, there is an inflatable cover made from the same material as your hot tub. This is used to cover the hot tub while you are using it, to keep the heat in. When you are storing it away or allowing it to cool down, you can use the hot tub lid. This is made of an imitation leather material that clips into place using a double set of durable clips on either side of the tub.

Lay-Z-Spa and Bestway: Behind the Brand

Bestway are actually the parent company of Lay-Z-Spa. This subsidiary was set up to deal with the sale of, research and development of, and manufacturing of, inflatable hot tubs suitable for use in the home. They make durable, hard-wearing, and long lasting hot tubs that are fully portable when not inflated or filled with water. They cater to a vast range of sizes, should you wish something bigger than the Lay-Z-Spa Siena, which is a two person model.

You can visit the Bestway site to learn more about the history behind the brand. Trust us when we say that they are known for great value products with an affordable price tag. The Siena model of inflatable hot tub is exactly such a product.

How do you setup the Siena?

Since the box is a little on the heavy side, we recommend that you take it to the room that you want to set your home hot tub up in before you unbox it. When you have chosen the place you want to keep your hot tub, take it out of the box and begin the process of inflating it. The air pump will help with this. The rapid inflation system should see it fully inflated with 10-15 minutes but be prepared to leave plenty of time to fill it. The filling time will vary depending on your water pressure.

Once your pool is filled with water, set the temperature on top of the control panel, and let the hot tub heat up. A Lay-Z-Spa home hot tub goes as hot as 40 degrees centigrade but this might be too hot for you, so always test the water before you jump in. After a few hours, your inflatable hot tub should be ready to get into.

If you get stuck with all of this, the Siena inflatable hot tub comes with a setup DVD which can guide you through how you operate it. Remember, Lay-Z-Spa have that UK based support team should you get stumped along the way.

Features that come with the Siena

When you invest in a Siena hot tub from Lay-Z-Spa, you get more than just a hot tub for two people. The best bits about this inflatable hot tub for your house are detailed in this section.

Stand out Features of the Lay-Z-Spa Siena:

  • 127 air jet massage system that churns the water to get deep into the muscles. To put this into perspective, some of their larger models have only 86/7 air jets, so this is a special feature.
  • Comfortable for two, luxurious for one.
  • TriTech fabric with a highly durable I-beam construction. This inflatable hot tub for your home won’t rip, tear, or leak.
  • Timer feature – the timer can be set up to 72 hours in advance for any planned events. It comes with that cut-off safety feature that we know and love from Lay-Z-Spa.
  • Comes with an easy to install DVD so you can always set it up, plus the support team are UK based if you need extra help.
  • It has a rapid dual-operated heating system which lets it heat up within the space of a few hours.

  • Chemical dispersing floater tool is included, as is a beverage table which clips into the design.
  • No tool setup with maintenance guidance on the setup DVD.

Lay-Z-Spa Siena Buyer’s Guide

We would be remiss in our duties if we didn’t describe the product as accurately as possible. Here is our guide to buying the best Lay-Z-Spa model for you – with a focus on the Siena.


The box will weigh 41 kgs when the inflatable hot tub arrives at your door. It is only once you start to fill it that the weight is added. It will hold 509 litres of water – more than some 4-6 person hot tubs – so when filled, it should never be moved around for the risk of tearing.

The Siena inflatable hot tub from Lay-Z-Spa is approximately 150 cm in length, 149 cm in width, and 58 cm in height. You should keep it in a space where there is plenty of air flowing around the entirety of the outside. The hot tub needs plenty of ventilation if indoors, so keep it in a room with large windows or an extractor fan.

Be careful of floorboards if having your Siena hot tub indoors. Your floors can only hold so much weight and 1 litre of water weighs just under 1 kg. So the Siena weighs a total of 548kg when filled.


The Siena inflatable hot tub is a light blue-grey on the outside, and a light blue on the inside. The blue-grey allows for a smart finish that looks suave in any yard or spare room.

Indoor or Outdoor Use?

The Siena home use inflatable hot tub can be used indoors or outdoors. As we mentioned above, look out for good ventilation and hardy flooring when stowing it indoors. Outdoors, look for a water/weather proofed extension cable so no electronics are getting wet. Many buyers put it in their garage since this is the best of both worlds.

Digital Controls

The digital control panel for the Siena inflatable hot tub are on top of the air pump. This keeps it removed enough from the water that it is unlikely to get wet, and means you can set the time and the heat, and jump in without any worries. The system will maintain the heat you like for as long as you like, without getting too hot.


Your Siena inflatable airjet powered home hot tub shouldn’t get hotter than 40 degrees centigrade. This is thought to be a little on the hot side for most people. Most of us like a hot tub set to around 36 degrees, but Lay-Z-Spa gives us those extra few degrees for those that like it especially hot.

Safety Features

This model of inflatable hot tub for your house will cut off if it gets to that 40 degrees – so you know you will never be boiled. It also maintains any temperature you set it to, for a timer that you can control up to 72 hours in advance. With the separate digital control panel being as waterproof as possible, there aren’t many reasons not to love the Siena Airjet inflatable hot tub.

Warranty and Guarantees

The Siena hot tub comes with a single year’s warranty, which is as standard. This will cover you for any failings the product has that are the responsibility of the manufacturer. If the product becomes damaged through something that you do to it, on the other hand, they are unlikely to give you a new one.

The warranty is extendable, meaning that you can go and register on the Bestway website and get more for your money. They will replace any hot tub damaged that is their responsibility.

What Customers Love about the Lay-Z-Spa Siena Airjet

There are a number of different things that customers in reviews were consistently impressed by. We listed those points which came up more than once, below.

The Airjets

Several customers buy this for the massaging effect of those airjets. That water blasting onto your body and heating it an ambient temperature is one of the most relaxing feelings you can buy – for your home.

The Healing Power

As an offshoot of the airjets, the massaging effect is perfect for those that suffer from back, limb, or neck pain. Several customers with bad backs and Fibromyalgia report a distinctive, noticeable increase in their ability to manage and soothe their symptoms… and all thanks to an inflatable hot tub!

The Setup

Unusually, people mentioned time and time again that the setup for the Siena Lay-Z-Spa is exceptionally simple. Whether it is the setup DVD or the ease with which this tub can be inflated, we’re not sure… but people love the simplicity of design.

The Sturdiness

Another comment we read over and over again was that this was highly durable, of a solid build, and lasted for years. When properly stowed away during the colder months (most hot tubs start malfunctioning at less than 0 degrees), this hot tub will last you for years to come.

The Size

For a two-person hot tub, the Siena inflatable model from Lay-Z-Spa holds more water than some 4-6 person tubs. You have plenty of space to move around in, plus you face each other so can share the romance.

What Customers Disliked about the Siena Airjet

Similarly, there were a few things customers mentioned in reviews that they didn’t enjoy so much.

The Maintenance

Cleaning and maintaining a hot tub does take time. It is a hobby that needs a little effort before you can reap the rewards. Filling, emptying, and cleaning the hot tub is a little time consuming. We would recommend you invest in the Lay-Z-Spa hot tub vacuum if you can afford to. The filters will require washing out every time you use it, which could be daily.

The Heating Time

Despite the rapid heating function which allows the Lay-Z-Spa to be warm enough to enter within 3 hours of switching it on – there are still people who complain about how long this takes. Hot tubs take time to fill up and time to heat up. Less than 6 hours to do so is a modern technological marvel.

Lay-Z-Spa Siena FAQs

In this section, we have tried to answer the most commonly asked questions regarding the Siena Lay-Z-Spa. It might be that the answers you are looking for are contained within.

Q) Could you fit more than two people in the Siena hot tub?

A) Actually, some reviewers mentioned both of them and their two children were in this model. We don’t recommend overloading capacity, but if you have two adults and two small children, you will have enough space. Never leave your children unattended in a hot tub.

Q) How long does it take to fill up the Siena Airjet home hot tub?

A) It can take anything up to an hour to fill up a hot tub for the first time. Generally speaking, it doesn’t take that long in the UK, since our water pressure is quite good. Be prepared to spend 3 hours minimum waiting for the rapid heating system to kick in though.

Q) Do inflatable hot tubs take much electricity to run?

A) Inflatable hot tubs have a low daily running cost. If you consider that the biggest energy user in the hot tub is the heater, and compare this cost to how much it would use to run an electric heater that plugs into your wall for the same amount of time, this gives you an idea of how much it uses. It isn’t a no-cost item, it’s a luxury item.

Our Verdict

The Siena is yet another sound model from Lay-Z-Spa. It’s durable construction and TriTech fabric mean that it has all it needs to be the perfect hot tub for young couples. If you happen to be a young couple looking for the best inflatable hot tub money can buy, then this model comes as close as you can get without personalisation.

A hot tub is a big spend. As we mentioned, it’s a luxury item… and the Siena feels as luxurious as a hot tub gets. Those 127 airjets are exemplary, and represent a large part of what you pay for when you buy this inflatable home hot tub.

The verdict? That those looking for a two person hot tub that is both comfortable and intimate, will love the Siena from Lay-Z-Spa. Inflatable hot tubs are the best home improvement you can take with you when you move and offer a little taste of luxury, in your own home or garden. We all deserve a little luxury now and then… so we say treat yourself!
