Published Feb 20, 2025

Hydropool offers two lines of tubs: Serenity and Signature. Some companies offer more or less, but we're happy with two. 

In this article, we want to explain each of the types of hot tubs we offer at Hydropool, so you can have a clear idea of what you’re looking for before you come into the store. 

We’re going to look at the Serenity and Signature collections. In general, the difference between the two lines is this:

  • Serenity has a lower upfront cost, with industry-competitive pricing, filtration and features. 
  • Signature is our premium line, with extra features, including our unique self-cleaning filtration system and advanced hydrotherapy, along with a wide array of customizable options and features. 

With each we’re going to go over:

  • What’s in each collection
  • Standard features
  • Pricing
  • Options

We are proud of both our Serenity and Signature collections of hot tubs. Here’s one way to think of them: The Hydropool Signature collection is a premium-priced product, with a unique self-cleaning system. The Hydropool Serenity line offers industry-standard cleaning and market-competitive pricing. 

By telling you exactly what we are, what we make and why we think it is best way to build a hot tub, we hope this article helps you decide if Hydropool has the right hot tub for you. 

What is the Hydropool Signature Collection?

Let’s back up. First of all, what is a “collection”? Essentially it is like a herd of cows or a pride of lions. A collection of hot tubs is a variety of hot tubs that are all linked, but all different at the same time. 

The following 13 hot tubs are in the Signature Collection:

Hydropool’s Signature collection is the top-of-the-line product for the company, and includes self-cleaning. For more on it, click here. The hot tub shown here is Hydropool's 579 Platinum. 

What Comes Standard in the Signature? 

What is a Self-Cleaning Hot Tub?  

What is Hydropool’s Self-Cleaning Feature in Hot Tubs? 

It’s the defining element of the Signature hot tub line. It’s a patented feature, designed to work exactly how public pools work.

But Hydropool began in this business as a commercial pool company. So it was only natural that Hydropool adapted the method of cleaning its hot tubs from commercial pools themselves. Then it patented the process, which is why Hydropool is the only hot tub builder that offers it. In short, Hydropool’s self-clean system is built to the same standard as commercial pools, which far exceeds any regulations or standards set for hot tubs. 

Our self-cleaning feature has three defining elements: 

  • First, one filter removes everything on the surface of the water, with the jets and pumps circulating the water to encourage it to head toward the filter. This type of filter is commonly used in the hot tub and swim spa industry.  
  • Second, on the bottom, a vacuum filter removes anything that falls to the bottom of the pool. This is not common and unique to Hydropool. It is common in public and residential pools, where it is often referred to as a drain but unique to Hydropool in hot tubs.  
  • Third, the tub or spa’s cleaning filter is placed after the pump, which causes the pump to push the water through the filter in a pressurized canister environment. It’s forced that way for a reason. It’s so the water can’t go anywhere but through the filter, to ensure 100 percent of the water is filtered through the cleaning system. 
Does Hydropool's Self-Cleaning Actually Work? 

The benefits of a self-cleaning hot tub are clear: 

  • The more cleaning the hot tub can do on its own, the less you must do as an owner. So one major benefit is that it is less work for any hot tub or swim spa owner. 
  • Self-clean is an easier way to get into hot tub spa ownership if it’s your first time buying. It’s one less thing to worry about once you have bought it.   
  • The other, more hidden benefit is that the hot tub or swim spa components don’t have to work as hard. Your Mom or Dad might have said something like "clean a little so you never have to clean a lot at once" about cleaning your room growing up, and they were both right – at least when it comes to cleaning hot tubs and swim spas. Over time, self-cleaning will cost you less in electricity as your power needs are less. 

You will still have to drain your hot tub from time to time if you buy a self-clean system. There's no maintenance-free hot tub (although our engineers are trying!) But it will make your life easier. 

If you want to read more about self-cleaning, we have this article devoted to explaining it.

What’s the Pricing on Signature? 

All prices were current at the time of writing and may change. For Signature hot tubs, prices typically start at under $14,000 (Cdn) and go up to just over $21,000. 

Want more specific pricing? If you look at the collection on our website, you’ll see prices are marked on each page for each individual hot tub. Not every hot tub company puts its actual prices out there for the world to see, but at Hydropool we believe in transparency. 

How Much Does a Hot Tub Normally Cost? 

What Options are Available on Signature Hot Tubs? 

Many hot tub companies only sell in packages. The effect is that it works like this: “You buy hot tub X and it comes with the following features. Do you want it?”

That is an entirely fine approach. There are many people who want to shop that way. But at Hydropool, we offer as much choice as possible, so you can customize your hot tub. 

Options include multiple cabinet shells a selection of acrylic colors. You can have your model blend in or stand out, whichever you like. 

Other popular options include:

  • a smart phone app that allows you to control your hot tub
  • an ozone system that helps you naturally keep your hot tub clean
  • multiple lighting options
  • an advanced hydrotherapy package
  • a choice of covers. 

Pros and Cons of One Pump Versus Two in Hot Tubs: Is Gold or Platinum Better? 

It’s easy to say that two pumps are better than one, and when it comes to hot tubs they are. You will get a better massage as your jets will have increased power and capabilities with two pumps as opposed to one. With one pump, your water’s circulation and the jets are being powered at the same time, and with two, you simply have more power available for your jets, which improves your massage. Two pumps also allow you to have more jets. 

Many people are happy with either system though. It depends on how important massage is for you.

There’s one other element to the decision: 

  • One pump will be cheaper to pay for upfront, but it will cost you more on an ongoing basis because that pump is working harder. 
  • Two pumps is the opposite: It costs you more when you buy the hot tub, but is cheaper to operate, as the pumps are not taxed as hard. One pump runs your jets, and the other circulates the water.  

To give you a sense of the cost, the difference between a Signature 579 Gold and a 570 Platinum is about $2500 (Cdn), at the time of this writing.  

Essentially, Gold allows people a less expensive way to get into the self-cleaning line of hot tubs. Platinum offers a top-of-the-line massage, along with self-clean and reduced operating costs.  

Why Don’t All of Hydropool Products Have Self-Cleaning if it’s the Best?  

The simple answer is that the industry standards for the hot tub and swim spa industry aren’t as high as the commercial and residential pool industry, given that both contain less water and are used by fewer people each time out. 

So there are other ways to clean hot tubs and swim spas than the way we have just explained – and these ways are also less expensive so that your upfront price is less. In the most common method, the vacuum filter doesn’t exist and the filter is placed in front of the pump, with the top skimmer doing a lot more of the work as a result. That combination is the industry standard (it also typically means you're buying a separate vacuum and using more chemicals but many people are fine with this).  

Without question, both systems work though and that's why we sell one collection that features each.

What is the Hydropool Serenity Collection? 

We just mentioned we had a line of hot tubs that uses the industry-standard method of cleaning. That’s the Serenity Collection. It has its own unique shell and other defining characteristics but carries many of the same options as the Signature. 

At the time of this writing, prices range in the Serenity from just under $11,000 (Cdn) for the base-model Serenity 4300 (see the individual product pages for pricing for each model).

The Serenity collection includes six models:

As with Signature:

  • The first number is the number of seats in the hot tub. 

What comes standard:

  • Thermal blanket insulation and steel frames are standard on all Serenities. 
  • A waterfall feature, with two pop-up waterfall jets, plus corner cabinet lighting.
  • A traditional hot tub filtration system features a skimmer on top, and a substantial grill to haul in all the debris that enters your hot tub. Dual filters keep your water clean, while a pump that moves 87 gallons per minute keeps them busy. It works, we promise. It just doesn't work the same way as our Signature self-cleaning line.
  • Zone Therapy jet massage
  • Serenity collection models all run on one pump for both the jets and circulation, so there’s no Platinum or Gold option here. 

Serenity Hot Tub Options

As with Signature, Hydropool is committed to offering you as many options as possible so that you can customize your hot tub. Options include: 

  • an app for your smartphone that gives you control of your hot tub from anywhere in the world
  • an ozone system that treats your water the same way drinking water is treated
  • an ozone and UV system that when combined do even more to keep your water clean
  • multiple acrylic colors for your shell and options for your outside cabinet so you can choose the color combo you'd like

Serenity hot tubs are a leader in value. The hot tub shown above is the Serenity 5900, a best seller.

Serenity vs Signature Hot Tubs: Which is Right for you? 

Hydropool sells two main lines of hot tubs: The Serenity and the Signature Collections. It’s not a surprise then that one of the most common questions we are asked is, “What’s the difference between Serenity and Signature collections?”

As with many of the decisions you have to make when buying a hot tub, there is no one “best” that wins out every time. There’s only what is best for you.

  • Serenity offers a lower upfront cost, with industry competitive pricing, filtration and features. 
  • Signature offers premium filtration and hydrotherapy, along with a wide array of customizable options and features, at a more premium price. 

Hydropool offers both these lines because it believes in offering as much choice as possible for each customer. We want people to get the hot tub that is right for them, and you can’t do that if you only make one model with a standard set of options. 

We try to offer as much customization as possible, even though we know it can be initially confusing for buyers when they first start considering us because of the multiple choices available to you, particularly in the Signature line. 

Customization does make production more difficult, and this in part explains our cost structure, and why the Signature, our more premium line, costs a little more than the Serenity. 

We wrote this article to help you understand what each collection had to offer, so you could consider what makes the most sense for you as a buyer. We believe both collections are good hot tubs for you to buy but ultimately, you have to decide which is best.
