Sauna vs hot tub
Choosing between a sauna and a hot tub is one of the most common garden wellness decisions UK homeowners face, and the answer depends on your health goals, budget and available outdoor space. At Gravity Wellness, a UK-registered company trading under York House Group (Company No. 15903905), we handcraft every sauna from sustainably sourced Canadian hemlock so you can make that decision with complete confidence in the quality behind each option.
Understanding the core difference: dry heat versus warm water
A sauna and a hot tub both provide warmth and relaxation, but they do so through fundamentally different mechanisms. A traditional sauna heats the air around you to temperatures typically between 70 and 100 degrees Celsius, causing your body to perspire heavily and triggering a wide range of physiological responses including elevated heart rate, improved circulation and deep muscular relaxation. The dry heat environment also has a pronounced effect on respiratory passages, making saunas a long-standing remedy in Nordic wellness culture for clearing airways and supporting overall vitality. At Gravity Wellness, our full sauna range captures this authentic heat experience in handcrafted Canadian hemlock cabins built to last for decades.
A hot tub, by contrast, immerses the body in water heated to between 36 and 40 degrees Celsius, relying on hydrotherapy and jet pressure to soothe muscles and joints. The warm water buoys the body, reducing gravitational load on the spine and limbs, which can be genuinely beneficial for those managing arthritis or chronic joint discomfort. However, the heat penetration of a hot tub is considerably shallower than that of a sauna, meaning the cardiovascular and metabolic stimulus is significantly lower. For garden wellness in the UK, where outdoor space is often at a premium, understanding these core differences is essential before committing to either purchase, and this guide is designed to give you the full picture.
Health benefits compared: what the evidence says
The health case for regular sauna use is supported by a substantial body of research. A landmark Finnish study published in JAMA Internal Medicine found that men who used a sauna four to seven times per week had a 50 percent lower risk of fatal cardiovascular events compared to those who used one only once per week. Regular sauna bathing has also been linked to reduced inflammation markers, improved endothelial function and enhanced recovery from intense physical exercise. For UK users exploring outdoor sauna vs hot tub options, these documented cardiovascular benefits represent a compelling argument in favour of a sauna, particularly when sessions are conducted consistently as part of a structured wellness routine. Our outdoor sauna collection makes it straightforward to build that routine right in your own garden.
Hot tubs offer genuine therapeutic value of their own, particularly for musculoskeletal conditions. Warm water immersion reduces cortisol levels and can improve sleep quality when used in the hour before bed, as the subsequent drop in core body temperature signals the brain to initiate sleep. They are also highly social spaces, making them attractive for households that prioritise shared relaxation over solo therapeutic sessions. That said, hot tubs require regular chemical treatment to maintain safe water hygiene, adding an ongoing maintenance burden that saunas largely avoid. A well-built sauna constructed from naturally antimicrobial Canadian hemlock, such as those available across our range including the one-person traditional sauna, requires only periodic airing and occasional light cleaning to remain in excellent condition.
Installation, running costs and practicality for UK gardens
From a practical standpoint, saunas hold a clear advantage for most UK gardens. Every sauna in the Gravity Wellness range operates at a maximum of 2000 watts, meaning it runs from a standard UK 13-amp socket without any need for specialist electrical installation or rewiring. Hot tubs, particularly those with multiple jets and heating systems, typically require a dedicated 32-amp or even 40-amp circuit installed by a qualified electrician, adding hundreds of pounds to the upfront cost before a single soak has taken place. Gravity Wellness is a UK-registered business operating under York House Group, Company No. 15903905, registered at Meadow House, Long Bennington Business Park, Newark, NG23 5JR, and we deliver to mainland England, Scotland and Wales with delivery included in the purchase price. Our two-person traditional sauna is a particularly popular choice for couples who want a meaningful wellness investment without complicated installation.
On-going running costs also favour the sauna in most scenarios. A typical sauna session lasting 45 to 60 minutes at 2000 watts costs roughly 60 to 80 pence at current UK energy rates, depending on your tariff. A hot tub, by contrast, must maintain its water temperature continuously around the clock, consuming between 1 and 3 kilowatt hours per day even when not in use, which translates to an additional monthly energy bill of 40 to 120 pounds depending on insulation quality and ambient temperature. For garden wellness in the UK, where cold winters can dramatically increase hot tub heating costs, the sauna represents a markedly more economical long-term choice. Each Gravity Wellness sauna is built to order from PEFC-certified Canadian hemlock, a wood recognised for its natural thermal properties and durability in outdoor conditions, with an approximate 60-day build and delivery window from the point of order.
Making the right choice for your home and lifestyle
Ultimately, the sauna vs hot tub decision comes down to what you want your garden wellness space to do for you. If your priority is measurable health outcomes, lower running costs, minimal maintenance and a product that improves with age, a sauna is the clear answer for the vast majority of UK buyers. If your priority is social bathing, hydrotherapy for specific joint conditions and a product that multiple guests can enjoy simultaneously at a lower upfront unit price, a hot tub may suit your lifestyle better. For those who want the health benefits of both, a sauna and cold plunge combination is an increasingly popular alternative that delivers the contrast therapy benefits associated with Scandinavian wellness traditions. Our four-person traditional sauna offers ample space for group sessions and is a favourite among families and households who entertain regularly.
At Gravity Wellness, every sauna we sell is handcrafted to order, meaning you are never purchasing warehouse stock that has sat in storage for months. Each cabin is built fresh by skilled craftspeople using sustainably sourced Canadian hemlock, a wood prized for its stability, warmth and natural antimicrobial properties that make it ideal for high-humidity heat environments. We believe that a premium sauna purchased once and maintained well will deliver a better lifetime return on investment than a hot tub, which typically requires pump, filter and shell replacements within seven to ten years. If you are ready to explore your options, our infrared one-person sauna is an excellent entry point for those new to home sauna ownership, combining gentle radiant heat with a compact footprint perfectly suited to smaller UK gardens.

Frequently Asked Questions
What is the fundamental difference between a sauna and a hot tub?
A sauna heats the surrounding air to between 70 and 100 degrees Celsius, causing the body to sweat profusely and stimulating cardiovascular responses comparable to light aerobic exercise. A hot tub immerses the body in water held at 36 to 40 degrees Celsius, using warmth and jet pressure to relax muscles and joints without the same level of heat penetration. The two wellness modalities feel very different in practice and deliver distinct physiological outcomes, making the choice highly personal and dependent on your specific health and lifestyle priorities.
Which delivers better health benefits: a sauna or a hot tub?
For overall health outcomes, the research strongly favours the sauna. A long-term Finnish study found that using a sauna four to seven times per week was associated with a 50 percent reduction in fatal cardiovascular events. Regular sauna use has also been linked to reduced inflammation, lower blood pressure and improved mental wellbeing. Hot tubs offer genuine benefits for joint pain and sleep quality but lack the depth of cardiovascular and metabolic stimulation that a sauna provides, making saunas the superior choice for those focused on long-term health improvement.
Which is easier to install in a UK home or garden?
Saunas are considerably simpler to install in a UK setting. Every Gravity Wellness sauna operates at a maximum of 2000 watts and plugs directly into a standard 13-amp household socket, requiring no specialist electrical work whatsoever. Hot tubs typically demand a dedicated 32-amp or 40-amp circuit installed by a qualified electrician, which can add several hundred pounds to the project cost before the unit is even filled with water. For most UK gardens, a plug-and-play sauna is the fastest and most straightforward route to a premium home wellness space.
Which costs more to run day to day in the UK?
Hot tubs are considerably more expensive to run on an ongoing basis. Because they must maintain water temperature around the clock, a typical hot tub consumes between 1 and 3 kilowatt hours per day even when not in use, adding an estimated 40 to 120 pounds per month to your energy bill depending on insulation and the ambient outdoor temperature. A Gravity Wellness sauna running at 2000 watts for a 60-minute session costs approximately 60 to 80 pence at current UK rates, meaning you only pay for energy when you are actually using the product.
Which does Gravity Wellness recommend for first-time buyers?
For first-time buyers in the UK, Gravity Wellness recommends starting with a traditional or infrared sauna over a hot tub. Our entry-level one-person models are compact, simple to set up via a standard UK socket and require minimal ongoing maintenance. Canadian hemlock, the wood used in every Gravity Wellness sauna, is naturally antimicrobial and remarkably durable, meaning the product improves with age rather than deteriorating. Each sauna is handcrafted to order with an approximate 60-day build and delivery window, so you can plan your installation with confidence from the moment you place your order.
