Delivery times are between 10 to 20 working days.
Delivery (Assemble Yourself Option):
If you choose to assemble the sauna yourself, we’ll deliver it directly to your doorstep using a tail lift truck. Our team will carefully unload the sauna and use a pump truck to place it as close to your desired location as access allows.
Delivery & Professional Installation:
If you select our professional installation service, our expert team will handle everything from delivery to full assembly. We’ll bring the sauna directly to your property, position it in your chosen location and complete the full setup — so you can sit back, relax, and enjoy your sauna from day one. All we need is a clear, level surface to build the sauna on. We strongly advise the use of a fully qualified electrician, to wire up the heater in order to be compliant with all Government Regulations.
If your order doesn't arrive within these timeframes please email us at - support@polar-recovery.com
At Polar Recovery, we stand behind the quality of every sauna cube we sell. That’s why we offer a 2-year guarantee on all sauna cubes — because your wellness experience should start with complete peace of mind.
To ensure your sauna stays in perfect condition for years to come, please follow these important guidelines:
If you're assembling the sauna yourself, make sure to apply a breathable wood oil or sauna-safe finish to both the inside and outside of the structure. This helps protect the wood and is required to activate your warranty.
Your sauna must be installed on a firm, level base to ensure smooth operation of doors and windows, and to prevent long-term structural issues.
Please inspect all parts upon delivery. If anything is missing or damaged, email us right away at Support@polar-recovery.com with clear photos and a short explanation — we’ll sort it for you.

What Voids the Warranty
At Polar Recovery, your satisfaction is incredibly important to us. We’re proud to offer beautifully crafted saunas designed to elevate your wellness journey — and we want you to feel confident in your purchase.
That’s why we’ve created a clear and fair returns policy to support you if things don’t go as planned.
If you change your mind before assembling your sauna, no problem — we’ll happily accept a return within 14 days of delivery, as long as:
Please note: once you start assembling your sauna, we consider the product accepted and in use. At that point, returns and refunds are no longer available. This is because the product can no longer be re-sold in its original condition.
If your sauna cube arrives with any damage or defects, don’t worry — we’ve got you covered.
Contact us within 48 hours of delivery at
Support@polar-recovery.com with your order number and photos.
This policy is fully aligned with the Consumer Rights Act 2015 and Consumer Contracts Regulations 2013. While you're entitled to cancel your order within 14 days of delivery, that right no longer applies once assembly has begun and the product is no longer in resalable condition.
We’re here for you. If you have any questions or need support with your order, just email our friendly team at support@polar-recovery.com — we’re always happy to help.
To keep your sauna looking great and lasting for years, a bit of post-assembly care is essential.
Here’s what we recommend:
2. Should you treat the benches too?
3. What should you use?
If you’re handy with tools and have someone to lend a hand, you can build your sauna in just a day. Most people prefer to split it over two — getting the outer structure up on day one, then fitting the bench and electrics on day two for a smooth, stress-free setup.
It’s a rewarding project and a great way to feel even more connected to your new wellness space.
YES! Want a Stress-Free Setup? Let Us Handle It.
Choose our professional installation service, and our expert team will take care of everything — from delivery to full assembly. We’ll bring your sauna to your property, position it exactly where you want it, and build it for you, so all you need to do is sit back and enjoy.
All we ask is that you have a clear, level surface ready for us to build on.
To stay compliant with UK safety regulations, we strongly recommend using a qualified electrician to wire in the heater once the sauna is assembled.
No, but please note:
A qualified electrician is required to connect your sauna heater to your power supply. At a minimum, an isolator switch must be installed for safe and compliant operation.
The simple answer is — it’s not needed.
This sauna cube is built using high-quality thermowood, which naturally has excellent insulating properties. Thermowood is heat-treated to reduce moisture content and increase thermal efficiency, helping it retain heat extremely well without the need for additional insulation.
Because this is a compact, well-sealed design, the heat is distributed efficiently and doesn’t have far to travel. The structure has been specifically engineered to minimise heat loss, maintain consistent temperatures, and create a fast, effective warm-up time — even in colder outdoor conditions.
So while traditional home builds may require added insulation, our sauna's material choice and design eliminate the need for it, without compromising performance or energy efficiency.
We ship all orders from our warehouses located near Weston Super Mare in the UK.
Yes, you can paint your sauna any colour you like — as long as you use a breathable wood treatment.
Breathable paints or wood finishes allow moisture to escape from the timber while still protecting it from the elements. This is especially important for a sauna, where the wood naturally expands and contracts with heat and humidity. Using a non-breathable paint (like standard exterior paint) can trap moisture inside the wood, which may lead to warping, cracking, or mould over time.
The 2.0 Oval has 3 x more insulation than the standard tub to keep the water colder for longer. The oval tub also has a much larger capacity making it more comfortable for larger individuals.
The 2.0 oval tub has 2 outlet valves for seamless mini chiller integration. Our mini chiller can still be used with the standard tubs but they only has 1 valve so the second hose will have to go over the top ring.
The 2.0 also incudes our new rain repellant thermo lid to prevent sag from water pooling in the top of your tub.
The Materials of the 2.0 have also been upgraded to be thicker and stronger than the standard tubs.

Take the plunge and experience all the benefits of cold water immersion.
Stepping into a sauna can trigger the release of endorphins, the body's natural chemicals that relieve pain and boost mood. This process helps to alleviate post-workout soreness and discomfort, leading to faster and more efficient muscle recovery.
Additionally, the warmth from a sauna can enhance joint flexibility and mobility, which is vital for muscle recovery. By relaxing and loosening your joints, your exercise movements become more fluid, reducing the chance of injury and promoting overall muscle health.
The heat from the sauna can Cause blood vessels to dilate which will enhance blood circulation to your muscles, potentially reducing the risk of cardiovascular issues.
A review 2019 review of research papers from Texas A&M University found cold water therapy reduces inflammation by constricting blood vessels and limiting the flow of inflammatory compounds to affected areas. It also stimulates the production of anti-inflammatory cytokines. Regular cold water baths can effectively manage inflammation, promoting faster recovery and overall well-being.
Saunas alleviate pain from conditions such as arthritis, joint inflammation, and sore muscles making training much easier & Recovering a breeze!
Regular cold water exposure reduces stress, anxiety, and depression symptoms by stimulating the vagus nerve and releasing mood-boosting neurotransmitters like dopamine.
Sweating from regular saunas may help to release toxins in the body, thereby increasing immune function and reduce the chance of getting sick.
Recent research shows that cold water exposure activates brown adipose tissue (BAT), which burns calories to generate heat through non-shivering thermogenesis. This increases metabolic rate and supports fat loss. Cold water therapy also improves insulin sensitivity, helping regulate blood sugar levels and prevent excess fat storage.
Regular sauna sessions can help boost energy by improving circulation, releasing feel-good endorphins, and reducing stress levels. The heat encourages better sleep, detoxification, and oxygen delivery throughout the body — leaving you feeling refreshed, recharged, and mentally clear long after you step out.
