Custom-Built Timber Saunas | Revival Space Pretoria

Considered Detailing

The Art of Precision Timber Sauna Construction

A bespoke sauna is an intricate convergence of high-heat timber physics, moisture-tight insulation, and fine architectural joinery. At Revival Space, we craft custom traditional Finnish dry saunas and modern infrared cabins built strictly to your spatial layout.

Using premium non-resinous, low-thermal-conductivity timbers (such as Thermo-Aspen, Western Red Cedar, and knot-free Nordic Pine), we fabricate ergonomic floating benches, frameless glass facade walls, concealed indirect LED backlighting, and precision intake/exhaust ventilation circuits.

✓ Premium Thermo-Aspen & Cedar tongue-and-groove cladding

✓ Multi-tier ergonomic floating benches with hidden fasteners

✓ Frameless glass frontages & integrated warm ambient LED channels

Frequently Asked Questions About Custom Saunas in Pretoria & Sandton

A bespoke custom-built timber sauna in Pretoria, Centurion, or Johannesburg typically ranges from R65,000 to R95,000 for a compact 2-to-3 person indoor cabin, R95,000 to R155,000 for a 4-to-6 person luxury glass-front sauna in Thermo-Aspen or Western Red Cedar, and R135,000 to R240,000+ for a freestanding weather-insulated outdoor garden or poolside sauna.

Sauna interiors require low-density, non-resinous timbers that do not spit sap or burn skin at 90 degrees Celsius. We specify Western Red Cedar, Thermo-Aspen, Obeche/Abachi for bench contact surfaces, and kiln-dried knot-free Nordic Spruce or Pine.

We construct an insulated stud cavity lined with high-density mineral wool and a continuous reflective aluminium foil vapour barrier taped at every seam, paired with a 20mm ventilation air gap behind the tongue-and-groove timber cladding and passive intake/exhaust vents.
