Portable multiuser sauna

A method for assembling a portable multiuser sauna comprising:

• coupling ten sidewall triangular structural panels together in a closed loop by compressively latching vertically extending edges of alternately oriented sidewall triangular structural panels;
• coupling five rooftop triangular structural panels together as a five sided pyramid on top of the ten sidewall triangular structural panels by compressively latching the rooftop triangular structural panels to each other and to five of the sidewall triangular structural panels, whereby the sidewall triangular structural panels and the roof building panels comprise an enclosure supported by the compressive coupling of the triangular structural panels without the need for a support structure;
• and
• installing a heater unit to provide at least one of heated air and steam within the enclosure.

A compression mounted triangular structural panel comprising:

• a substantially planar outer surface configured as a first equilateral triangle having a first set of three congruent edges and defining a first centroid;
• a plurality of compression connectors coupled to the outer surface proximate to a plurality of edges of the first set of three congruent edges;
• a substantially planar inner surface configured as a second equilateral triangle having a second set of three congruent edges and defining a second centroid, wherein edges of the first set of three congruent edges are longer than the edges of the second set of three congruent edges, wherein each edge of the first set of three congruent edges is substantially parallel with a corresponding edge of the second set of three congruent edges, and wherein an axis through the first centroid and the second centroid is substantially perpendicular to the outer surface and the inner surface;
• and
• three compression sidewalls extending between corresponding edges of the first set of three congruent edges and the second set of three congruent edges.
