Titan Dual Heat Sauna with 6KW wifi enabled Harvia upgrade: A Masterclass in Technical Negligence and Safety Risks
As an Aerospace Systems Engineer of many years and DIY enthusiast, I am appalled by the level of technical incompetence and lack of customer support displayed by LIT Method. While the physical materials of the sauna are decent, the documentation and wiring provided for the 6kW "upgrade" are not just poor—they are dangerously incomplete. Coupled with blatantly incorrect guidance from their support team, it is a wonder I didn't burn my house down.
If you are considering this unit, be prepared to do your own engineering, as LIT Method’s support and manuals are a serious liability.
1. The wiring disaster
LIT Method’s support staff explicitly stated in writing that a single circuit is sufficient for this unit. The "instructions" also show a single cable leaving the sauna. After preparing as much as possible for delivery by having an electrician pull a single 30A circuit and installing a single breaker disconnect box, I was understandably confused when presented with two separate cables leaving the sauna. When I asked support for a simple wiring diagram of the sauna, they deflected over and over referring back to their terrible documentation, website specs, and the manual that comes with the Harvia heater. Never once after 2 weeks of back and forth was I able to gather any relevant wiring info about the infrared/lights/speakers portion of the sauna.
Furthermore, the 6KW Harvia heater upgrade that I opted for has a high temp safety circuit. Harvia's documentation clearly shows it, and the LIT "instructions" even vaguely reference the terminals in a single picture. Funny thing is, they don't supply a pair of wires for it, nor any way for said wires to exit the sauna to connect to the controller. I had to make my own harness for this, sheath it, and modify the sauna to penetrate the wall in a sealed fashion.
Eventually, with the help of my electrician, I was able to get both sides of the system connected and working (to my single circuit, which isn't ideal, but since the system won't allow operation of both heaters simultaneously anyway, I feel it is a reasonable solution). The best option would be to start with either a single 40+ amp circuit or two 20A circuits.
2. Quality Assurance (QA) and Terrible Support
The glass assembly process, and again incredibly poor instructions resulted in many days of fighting with the glass, damage to the interior from a subsequent rain storm, and needing to make my own pieces to complete the assembly. The glass arrived with some panels bowed. Not so much as you would complain, but enough to prevent them seating into the channels properly. The instructions don't detail the overlap method at the main glass corner, and thus, through my mistake, the corner joint overlap was biased in the wrong direction, resulting in a 1/16" interference for door closure. As expected with hindsight, no amount of hammering the front side further with a rubber hammer or adjustment of door hinges (the only suggestions provided by support) could resolve the issue. A simple graphic in the instructions showing the the front face needs to overlap the side face of glass would have prevented this assembly error.
When presented with video evidence of the mismatch, support deflected, claiming "it assembles as designed" because they’ve "sold thousands." This is "gaslighting" as a customer service strategy and patently un-helpful when you're staring a weather sensitive unit with no roof and storm clouds approaching.
Because of the incomplete and conflicting electrical data provided and the poor instructions and support around the door, my assembly was delayed by many days. During this time, the unit was exposed to a storm and the interior wood was drenched. LIT Method took zero responsibility for the consequential damage. They refused to escalate the discussion at my request to a technical lead and ignored every specific discrepancy or documentation shortcoming I raised.
3. Shipping Delays
Ordered in November 2025 with a stated lead time of "about a month". Sauna eventually arrived in March 2026.
4. Final Verdict
LIT Method is selling a "Kit of Parts," not a "System." It is clear they want to sell it and forget it and do not care about the customer experience at all beyond cashing your check. They are technically over their heads with the electrical integration and demonstrate no desire to improve. If you do not have a background in electrical engineering and a penchant for problem solving, do not buy this sauna.
Their website claims "Most customers complete setup in just 1–2 hours with minimal tools required.". This is laughable. Even if everything had gone perfectly, it would have been a full day of effort.
Pros: High-quality wood. Cons: Dangerously incorrect documentation and an ineffective support team.
