Hard Sided Hot Tubs | Rigid Foam Hot Tubs

Hard Sided Hot Tubs Image

Hard sided hot tubs Are much more robust and hard-wearing than your traditional inflatable hot tub because both the inner and outer body of the units are made up of much more durable materials than standard inflatable hot tubs and you can expect them to last much longer even with constant use.

There are typically three different types to choose from.

  • Rigid Foam Hot Tubs

Rigid foam walled hot tubs are made up of thermal efficient sturdy rigid foam walls to the inner side with strong exterior PVC linings that are hard-wearing and much more durable than standard inflatables.

  • Drop Stitch Hot Tubs

Drop stitch walled hot tubs are made up of double compressed fabric making the unit super sturdy and lightweight at the same time as allowing more room inside due to the thin but hard wearing design of the walls.

  • Plastic Panel Hot Tubs

Plastic panel walled hot tubs come as a flat pack hot tub with sturdy plastic panels to the outer layer and a strong PVC inner lining, the benefits of this type of tub is that don’t only last much longer than inflatable models but they are super simple to set up and more convenient to store away in the original box than inflatable models that can be.

Listed further below are some of the most popular hot tubs in the hard sided range along with the pro’s and con’s of each one we manually reviewed.

Canadian spa hot tub image

The swift current V2 is a follow-up model that was made after the original model which was the Canadian Spa Rio Grande 4-person hot tub which we covered on this website a couple of years ago, still a real contender in the hard-sided hot tub market only much cheaper.

Foam Constructed Walls

The swift current is made up of foam walls making it a more solid sturdy construction at the same time as offering more insulation due to it’s foam insulated walls which help keep the heat in the tub, that being said they are a little more hassle to set up compared to others as you have to place each piece of foam inside the walls to construct the unit which you can expect to take up to 15 minutes to complete.

The external walls are made up of tough PVC material which is both strong and durable compared to inflatable hot tubs like the popular Lazy spa models, The swift current is more of a luxury model with deeper walls that allow you to emerge into the water up to your neck and relax, it has three-speed controls which allow the jets to pump as little or as much as you like.

Heating Functions

The heating function allows you to turn the heat up or down to suit you, Easily adjusted using the built-in external control panel, this particular tub will hold the heat in much colder temperatures, therefore pretty it’s usable all year round, whereas a typical inflatable tub would struggle to hold the heat in much colder temperatures whilst eating away at your electric trying to keep the tub hot for you.

  • Well made with a solid construction that is made to last.

Are Hard Sided Hot Tubs Better Than An Inflatable?

Yes, Although they are slightly more expensive it is well worth your investment in the long run if you want your hot tub to last a long time compared to the cheaper inflatable models such as your Lazy Spa which can very easily become prone to punctures due to the materials used to build them.

Punctures on inflatable models come from simple accidental things such as a finger ring snagging on the material causing air leakage, Or pets such as cats and dogs can also puncture the side walls or top cover just with their claws.

Another known problem is cigarette burns to the sidewalls, typically to the outside walls which can easily be fixed with a repair kit but is something you can do without, with a hard-sided tub these simple little mistakes are automatically fixed with the durability of hard sided portable hot tubs with sturdy rigid foam walls.

These typical types of accidental damages are completely eliminated whilst having a solid construction hot tub that is typically made up of either sturdy plastic panels, drop stitch, or foam walled construction which make for a much more sturdy hot tub along with a much nicer look and feel to the material which is made up of extra layers of heavy-duty vinyl coverings for added protection.

Are They Suitable For Hiring Companies?

Hot tubs with a hard side are also much more suitable for hiring companies wishing to rent out hot tubs as the customer would have received a better experience and the hiring company is much less likely to have any damages or defects to the tub resulting in an overall better experience for both the renter and the hiring company.

There are not so many buying options with hard-sided portable hot tubs as there are with the cheaper standard inflatable hot tubs that are available, In this review, we will cover what we think to be the best ones available to you.

Final Conclusion:

The main benefits to owning a hard sided hot tub rather than standard inflatable hot tubs are that the rigid foam hot tubs are more thermal efficient and energy saving, Whilst the plastic panel and drop stitch hot tubs are designed to last longer being much stronger and more durable compared to inflatable hot tubs which simply won’t last as long in comparison.

  1. Hi Simon,
    Thank you for your great reviews.
    Can you tell me if the rigid foam sides to the hot tubs are strong enough to carry an adults weight. As I’m disabled, I need to sit on the side to lower myself in to the hot tub. What sort of weight would the sides take?

    1. Hi Helen,

      The MSPA Tuscany would be your best bet being made up of plastic sturdy walls that will take the weight of a 10 to 12 stone person sitting on the side, for the foam walled style hot tub, though they are very sturdy, being disabled you would either need a hoist to lift you in carefully or maybe some side steps to spread out the weight while you lean on the side would Possibly help.

      The only other possibility would be to go for a portable hard shell hot tub where you could certainly sit on the side to lower yourself into the tub, only the hard shell hot tubs do cost more to buy in.

      Take a look at my most recent review

      Sorry I Couldn’t help you more.

      Kind regards,


  2. Hi ,rgarding the new hard sided tuscany spa it is hardsided but to me doesn’t seem to have any insulation jut pvc side panels. So effectively it’s a pool with jacuzzi pump. Not ideal for keeping the temperature up unless you don’t mind spending a fortune keeping it heated . Have you got any info regarding insulation on the product?

    1. Hi Gareth,
      Internally the Tuscany has a 6-layer, reinforced, Rhino-Tech PVC inner lining which provides resistance and strength from wear and tear, Yet It’s not designed essentially to keep the heat in, NO sorry, you would be looking at around £1.50 per day to keep it heated, By using the top covers when the tub is not in use, will help keep the heat in.

      If your looking for a model with better insulation then the foam-sided hot tubs such as the Cosy-Spa deluxe would be a better option for you when it comes to heat retention but they are more expensive to buy-in.
      Hope this helps answer your question.
