Trumpkin's extensive notes on building a sauna have stirred quite the buzz among sauna enthusiasts and builders alike in online forums such as Reddit. With a manuscript that rivals the length of a book, Trumpkin takes readers through a deep dive into the intricate details of sauna design, dynamics, and construction. As with any extensive guide, there's a mix of valuable insights and a few contentious points. This blog will dissect Trumpkin's guidelines, highlighting key takeaways, areas for improvement, and how to build a sauna that truly embodies the essence of a Finnish sauna experience.

Overview of Trumpkin’s Notes

Trumpkin’s document is an ambitious effort to consolidate a comprehensive guide on what makes a good sauna. He covers various aspects, from the importance of convective heat to design principles that prioritize user experience. However, given the complexity and sheer volume of the content, it’s clear that some areas would benefit from more editing and clarity. Let’s break down the core concepts Trumpkin addresses and see how they stack up against expert advice.

Key Design Principles from Trumpkin

1. Feet Above the Stones: A cornerstone of Trumpkin’s design philosophy, this principle is derived from traditional Finnish sauna practices where benches are placed high enough to ensure that bathers’ feet are above the heater stones. The rationale is that this position offers more even heat distribution and avoids the dreaded “cold toes” phenomenon.

2. Proper Ventilation: Trumpkin emphasizes the critical role of ventilation in maintaining air quality and ensuring the removal of CO2, VOCs, and other contaminants. He suggests a downdraft ventilation system, ideally mechanical, for electrically heated saunas.

3. Larger Sauna Rooms: Trumpkin argues that a typical family sauna should be at least 8'x8'x8.5'. The reasoning is that a larger space promotes more even heat distribution and reduces the discomfort caused by radiant heat from the walls or heater.

4. Minimal Radiant Heat: According to Trumpkin, bathers should feel no significant radiant heat from the heater or surrounding walls. This is to ensure that the convective heat evenly envelops the body from all directions, maintaining a comfortable and consistent temperature.

5. Focus on Air Quality: Trumpkin places a high value on continuous fresh air, free from harmful elements like bacteria, mold, and excess CO2, which he believes is essential for a healthy and enjoyable sauna experience.

6. Calm and Quiet Environment: A peaceful, distraction-free environment is a key element of Trumpkin’s sauna philosophy. He highlights the importance of quiet spaces to enhance relaxation and ensure a proper sauna experience.

Expert Analysis and Critique

While Trumpkin’s notes provide a thorough starting point for sauna enthusiasts, some of his recommendations are either overly rigid or lack the nuance needed for practical application. Let’s dive deeper into the critique of some key areas:

1. Bench Height and Ceiling Requirements

Trumpkin insists on benches that are at least 20 cm above the stones and ceilings that are around 8.5’ high. While this setup may work well in Finland where taller ceilings are common, it’s not always feasible in the U.S. or other regions where building codes and architectural norms differ. Furthermore, this one-size-fits-all approach doesn’t account for smaller, personal saunas where space is a constraint. A more flexible recommendation would consider the specific use case and adjust accordingly.

Incorporating Saunum for Better Climate Control:

Trumpkin acknowledges the challenges of achieving optimal bench height in many settings and suggests that solutions like the Saunum can bridge the gap between traditional sauna principles and modern limitations. Saunum works by circulating air to mix the hot air at the ceiling with the cooler air at the floor, creating a uniform temperature distribution throughout the sauna. This technology allows for a balanced sauna climate even when the ideal bench height cannot be met, effectively preventing the “cold toes” issue and ensuring a consistent heat enveloping the body. It’s a smart integration that modernizes traditional practices while preserving the core sauna experience Trumpkin values.

2. Ventilation Systems

Trumpkin’s advocacy for downdraft mechanical ventilation systems is sound but doesn’t explore alternative methods that might be more accessible or practical for different types of saunas. For example, natural cross-ventilation can also effectively manage air quality without the need for complex mechanical systems, particularly in smaller or outdoor saunas.

3. Radiant Heat Reduction

While Trumpkin’s emphasis on minimizing radiant heat is valid, the reality is that some level of radiant heat is inevitable, especially in smaller sauna spaces. The key is to balance radiant and convective heat rather than eliminating radiant heat entirely. Moreover, some users may prefer a bit of radiant warmth as part of their sauna experience.

4. Room Size and Proportions

The recommendation for large sauna rooms might not always be practical, particularly for home installations. While spacious saunas do offer a more even heat experience, not everyone has the luxury of space or the budget for a large build. The focus should be on optimizing whatever space is available, rather than adhering strictly to specific dimensions.

5. Material Choices and Build Considerations

Trumpkin touches on the use of softwoods like spruce, pine, and aspen for walls, benches, and ceilings, while cautioning against materials like cedar that can off-gas harmful compounds. This advice is generally well-founded but could benefit from a broader discussion on sustainable sourcing and the environmental impact of different materials.

Creating a Good Sauna Climate with Saunum

A significant challenge in adhering to Trumpkin's principle of having feet above the heater stones is the physical constraints of many home or smaller saunas. Fortunately, the Saunum offers a modern solution to this issue by creating an optimal sauna climate without the strict need for elevated benches.

What is Saunum?

Saunum is a revolutionary air circulation device designed specifically for saunas. It works by mixing the hot air at the ceiling with the cooler air at the floor, creating a uniform temperature distribution throughout the sauna. This system allows users to enjoy the classic Finnish sauna experience of even, convective heat without the necessity of having their feet above the heater stones.

How Saunum Enhances the Sauna Experience:

1. Even Heat Distribution: Saunum's air circulation mechanism eliminates the stratification of temperatures within the sauna. This means no more "cold toes" or overly hot heads—just a consistent, enveloping warmth from head to toe.

2. Improved Air Quality: By continuously circulating air, Saunum also helps to maintain lower CO2 levels and ensures that fresh, oxygenated air is available for bathers. This contributes significantly to a healthier and more comfortable sauna environment.

3. Flexibility in Design: With Saunum, the stringent design constraints advocated by Trumpkin become more flexible. Saunas can be designed with lower ceilings or alternative bench arrangements without sacrificing the quality of the heat or the overall experience.

4. Energy Efficiency: Saunum’s ability to evenly distribute heat can also result in more efficient use of the sauna heater, potentially reducing energy consumption as the sauna doesn't need to overcompensate for uneven heating.

Why Saunum is a Game Changer:

While Trumpkin’s notes provide a strong foundation for traditional sauna design, innovations like the Saunum bring the sauna experience into the modern age. By addressing common challenges such as uneven heat and air quality, Saunum allows more flexibility in sauna construction without compromising on the essential elements of a Finnish sauna.
