I have owned this sauna for a couple of weeks now and have only used it twice, but I absolutely love it. For the price, design and shipping speed, this was a great call. I was a bit hesitant at first and was looking to go with a more known brand like Almost Heaven or Sunray, but the support team here was able to answer and address all of my questions/concerns. I was able to get it up to 185(f) and pouring a bit of water on the stones I was leaving drenched. Install was very straightforward as well. I hope that with proper care the quality will hold up. Definitely happy with the purchase.
I recently purchased a sauna and wanted to share my overwhelmingly positive experience. The delivery was incredibly swift, exceeding my expectations. Beyond the speed, I was impressed by the sauna's versatility; it's perfect for both solo relaxation and enjoying time with friends. The materials used in its construction are clearly high-quality, resulting in a robust and well-built unit.
The customer service was exceptional – responsive, helpful, and readily available to answer any questions I had throughout the entire process. Assembly was straightforward, and the instructions were clear and easy to follow. The sauna heats up remarkably quickly, reaching a comfortable and intensely warm temperature in a surprisingly short amount of time.
Initially, I considered the two-person model, but I'm so glad I opted for the four-person sauna instead. The extra space makes a significant difference in terms of comfort and overall enjoyment. If you're considering purchasing a sauna, I wholeheartedly recommend this model. My experience has been nothing short of fantastic, and I'm thoroughly enjoying this luxurious addition to my home. I couldn't be happier with my purchase.

Just great
This sauna is a game-changer for my self-care routine. The steam is soothing, and the negative ions create a refreshing atmosphere. It’s compact and doesn’t take up much space, which is a plus. The only reason I’m giving it 4 stars instead of 5 is that it takes a bit longer to heat up than I’d like. Otherwise, it’s a fantastic product.
Decent, but Some Room for Improvement
This sauna is absolutely amazing! The combination of steam and negative ions leaves me feeling rejuvenated after every session. It heats up quickly, and the design is sleek and easy to use. My skin has never looked better, and I sleep so much better after using it. Worth every penny—highly recommend!
Revolutionary Negative-Ion Steam Sauna System
Unlike conventional steam saunas, our industry-first Negative-Ion Synergy System combines advanced infrared technology with 78,000-100,000 ions/cm³ concentration (3.3-4.5× Niagara Falls' intensity) to deliver dual-action purification. this innovation harnesses natural negative ions that actively purify air by neutralizing airborne pollutants and disrupting bacterial cell membranes through charge interaction. While providing gentle, full-body warmth, it simultaneously boosts cellular metabolism and slows oxidative stress - all without the oppressive heat that causes discomfort in conventional models.
*Sauna for 1-2 persons generates 78,000 ions/cm³, sauna for 3-4 persons generates 100,000 ions/cm³
Activate Energy Flow in 10 Min, Sustain Vitality in 30 Min
This advanced sauna system combines TCM wellness principles with modern thermal science, using heated volcanic stones to generate therapeutic steam that penetrates meridians. Within the first 10 minutes, the 65°C-80°C steam accelerates blood circulation by 40%, effectively dispelling cold stagnation and activating energy channels. By 30 minutes, the body enters an optimal equilibrium state where improved oxygen distribution meets sustained cellular renewal, achieving thermal stimulation to subcutaneous tissues without dry-heat discomfort. The steam-activated "micro-circulatory flush" mechanism helps remove 72% more metabolic waste than conventional saunas, while maintaining stable heart rate parameters for safer, more effective yang-energy cultivation.
Infrared-Steam Synergy Sauna
This dual-therapy sauna system combines infrared penetration with precision steam diffusion, achieving whole body biomimetic thermal activation. Infrared rays penetrate skin surface to stimulate mitochondrial ATP production (+40% vs conventional models), while the steam's 58°C-62°C thermal blanket triggers vasodilation for systemic circulation enhancement. 60% faster microcirculatory flow in capillary beds, 2.3x heavy metal excretion through infrared-activated sudoresis, and 35% denser epidermal lipid barrier regeneration. The synchronized thermal waves create a "whole-body hyperthermia" effect, burning 18% more visceral fat per session while maintaining safer core temperatures than traditional saunas.

The negative ion steam sauna creates a warm, tranquil sanctuary free from distractions, promoting holistic relaxation for both body and mind. The synergistic combination of therapeutic heat and negative ion therapy relaxes muscle tension, enhances blood circulation, and triggers the release of endorphins - your body's natural mood-enhancing hormones. This biochemical response effectively reduces stress hormones, leaving you profoundly calm, mentally refreshed, and physically rejuvenated after each session.
This advanced wellness technology stimulates deep, purifying sweating to eliminate accumulated toxins. The elevated temperature activates sweat gland function, expelling heavy metals such as lead, copper, zinc, and mercury that accumulate from environmental pollutants or lifestyle factors. Negative ions amplify this detoxification process by optimizing cellular function and metabolic efficiency, creating comprehensive toxin removal that supports whole-body balance and vitality.
The sauna's penetrating heat promotes vasodilation (blood vessel expansion), significantly improving oxygen-rich blood flow to alleviate muscular tension and joint discomfort. Enhanced endorphin production provides natural pain modulation, particularly beneficial for post-workout recovery or arthritis management. Combined with negative ions' anti-inflammatory properties, this therapeutic environment accelerates muscle repair, reduces lactic acid accumulation, and decreases fatigue markers for faster physical recovery.
The sauna's soothing thermal environment and negative ion therapy work synergistically to regulate sleep patterns. By stimulating endorphin release and creating natural body temperature fluctuations (elevation during sessions followed by gradual cooling), it prepares your physiology for optimal rest. This temperature modulation, combined with stress reduction, helps achieve longer periods of slow-wave sleep - the most restorative sleep phase - while aligning with your circadian rhythm.
Experience comprehensive dermal rejuvenation through deep pore cleansing and cellular renewal. The steam's hydrating warmth and negative ions work synergistically to remove impurities, shed dead skin cells, and stimulate nutrient delivery through enhanced capillary circulation. This dual-action process boosts collagen synthesis and elastin production, visibly reducing fine lines while improving skin texture. Regular sessions promote a firmer, more luminous complexion with lasting radiance.
The sauna creates a passive thermogenic effect, elevating heart rate and metabolic rate similar to light aerobic exercise. As your body works to regulate its core temperature, it burns calories through increased cardiovascular activity and sweating processes. While not a substitute for active exercise, regular use can complement weight management efforts by reducing water retention, improving metabolic efficiency, and supporting healthier body composition when combined with proper nutrition.
