Review:
I’ve been using the RelaxCube steam sauna for a few weeks now, and it’s become one of my favorite wellness investments. Setting it up was a breeze—everything was clearly marked, and I appreciated the thoughtful addition of gloves to avoid handling fiberglass with bare hands. Once assembled, the sauna felt sturdy and well-built, with reinforced crossbars ensuring stability.
One of the standout features is the 1200W steamer, which heats up quickly and provides a steady steam flow. I usually let it preheat for about 15-20 minutes, and it creates a comfortable environment for relaxation. The VOC-free materials give me peace of mind, knowing I’m not exposing myself to harmful chemicals during my sessions.
The size is perfect—it fits comfortably in my home gym without feeling cramped. At 6’1”, I had no issues sitting comfortably inside, and the ergonomic chair provided decent support. That said, the chair’s durability could use some improvement, as I’ve noticed reports of tears and breakage from other users. I plan to replace it with a sturdier option for long-term use.
While the steam sauna delivers on relaxation, it does fall short in temperature performance. The maximum temperature I’ve reached is around 105°F, which is pleasant but not as hot as I’d prefer. If you’re looking for intense heat, this might not meet your expectations.
Overall, the RelaxCube is an excellent choice for anyone seeking an affordable, home-friendly steam sauna. Its safety features, ease of use, and comfortable design make it a worthwhile addition to your wellness routine, even with a few minor drawbacks.
Pros:
- Safe and VOC-Free: Meets US ASTM-D5116 standards for a chemical-free experience.
- Spacious and Sturdy Design: Accommodates taller users and feels durable during use.
- Quick Heat-Up: 1200W steamer heats efficiently, creating a relaxing steam environment.
Cons:
- Limited Maximum Temperature: Struggles to exceed 105°F, which may not satisfy those seeking higher heat.
- Chair Durability Issues: The included chair is prone to tearing and breakage over time.
