Cube saunas pair a clean, architectural look with generous headroom and flexible bench layouts. Choose electric traditional heaters for classic high heat with steam, or select infrared panels for lower ambient temps and quick starts. Options range from compact 2-person cubes to spacious family cabins.
Modern Aesthetic: Flat rooflines, large glass, and crisp profiles.
Room to Stretch: Square footprint maximizes benching and legroom.
Multiple Heat Types: Traditional electric or full-spectrum infrared.
Indoor or Outdoor: Finish choices and weather packages available.
Frequently Asked Questions
What defines a “cube” sauna?
A cube (or square/cabin) sauna uses straight walls and a flat or gently pitched roof for a modern look and maximum interior volume versus round barrels.
Are cube saunas better indoors or outdoors?
They work in both settings. Indoors, you get sleek lines and easy furnishing. Outdoors, add a weather package, proper roofing, and a level pad.
Electric traditional vs infrared—how do I choose?
Traditional offers classic high heat with optional ladle steam (usually 240V). Infrared warms the body directly at lower ambient temps; many 1–2 person IR cabins run on 120V.
How hot do cube saunas get?
Traditional cabins: ~160–195°F (71–90°C). Infrared: many users enjoy ~120–150°F (49–65°C) due to direct radiant warmth.
Do cube saunas support panoramic glass?
Yes—many models offer large front glass or corner windows. Consider privacy, views, and solar gain.
What size is right for me—2, 3, or 4 person?
2-person fits corners and small rooms; 3–4 person offers legroom and social seating. Check external dimensions and door swing.
Can I place a cube sauna on a deck?
Yes—ensure the deck is engineered for the load and perfectly level. Use shims as needed and protect from standing water.
What kind of base do I need outdoors?
A level, well-drained pad: concrete, compacted pavers, or engineered deck. A flat base prevents racking and sticky doors.
What electrical is required?
Traditional heaters typically need a dedicated 240V circuit. Many 1–2 person IR models use 120V; larger IR can require 240V. Hire a licensed electrician.
Do cube saunas need ventilation?
Provide basic intake/exhaust and crack the door after sessions for drying. Follow the brand’s ventilation guidance.
How do I maintain a cube sauna?
Wipe benches, prop the door to dry, clean glass, and follow periodic checks for heaters/panels and connections. Re-seal exterior wood outdoors.
Any permit or HOA concerns?
Some municipalities/HOAs require approvals—especially if wood-fired. Verify codes, setbacks, and electrical runs ahead of time.
Buying Guide: Choosing a Cube Sauna
🔥
Heat Type
Traditional (Electric): Classic high heat + steam; precise controls; typically 240V.
Infrared (IR): Lower ambient temps, faster warm-up; many 1–2 person models are 120V.
📏
Size & Layout
2-Person: Compact footprint; perfect for corners.
3–4 Person: Wider benches, more legroom.
Glass vs Wood: More glass = open feel; more wood = warmer retention.
🏠
Placement
Indoor: Moisture-aware finishes; nearby power.
Outdoor: Level pad, overhang/roof, weather sealing, and electrical plan.
Confirm exterior dimensions plus door swing; leave 6–12″ service access near controls/power inlet.
Ceiling Height
Most cubes fit 7–8 ft rooms; verify model height and any top clearance requirements.
Flooring
Level, moisture-tolerant surface (tile, sealed concrete, select LVP). Avoid carpet; use a mat outside the door.
Electrical
Traditional electric: dedicated 240V. Infrared: 120V for many 1–2 person, 240V for larger/full-spectrum. Licensed electrician only.
Outdoor Base
Concrete or paver pad with drainage, or engineered deck. Keep perfectly level to prevent racking.
Roof / Weather
Flat rooflines benefit from drip edges and modest overhangs; maintain exterior sealants per schedule.
Glass & Privacy
Plan sightlines for large glass/fronts; consider frosted options or screening where needed.
Ventilation
Provide intake/exhaust per brand guidance; crack the door post-session to release humidity.
