What Affects the Cost of Custom Sauna Design & Installation
Custom sauna pricing varies with size, wood, heater, and indoor-vs-outdoor. The number depends on:
- Size. A 4’×5′ two-person sauna is the entry point. 6’×7′ four-person rooms are most common. 8’×8’+ family rooms and outdoor cabins scale up from there.
- Wood selection. Western red cedar is the standard. Nordic spruce and hemlock are slightly less. Thermo-aspen and African abachi are premium upgrades.
- Heater. Standard 6–9kW electric heaters are mid-tier. Wood-burning heaters need a chimney run. Air-circulation and humidity-control heaters are the premium tier. We carry every major brand and will spec what fits your room.
- Indoor vs outdoor. Indoor conversions are the simplest. Outdoor builds add foundation, exterior cladding, roof, weather sealing, and a buried electrical run.
- Glass & doors. Full-glass cedar-frame doors look spectacular and cost more than wood. Glass walls and picture windows are popular for outdoor builds.
- Permits & electrical. A new 30–60A dedicated circuit and city permit are standard line items. We include them in the quote — no surprise adds at the end.
We'll quote your build flat-rate after the design phase — heater, wood, electrical, and permit all included.

Frequently Asked Questions
How long does a custom sauna take to design and build in Newport Beach?
Design to first session typically runs 6–10 weeks. Design and 3D rendering takes 1–2 weeks. Permits and rough-in are 2–4 weeks. Finish carpentry, heater install, and curing is 2–3 weeks.
Indoor or outdoor — which is right for me?
Indoor is faster, cheaper, and warm in winter. Outdoor offers a true cabin experience but adds foundation, roof, and weatherproofing cost. We design either; we’ll walk you through the tradeoffs on the design call.
Electric, wood-burning, or infrared?
Electric is the most common — fastest to heat, easiest to operate, fits any space. Wood-burning needs a chimney and burn permit. Infrared is a different experience entirely (lower temp, gentler heat) and works in spaces where Finnish-style isn’t possible. We’ll spec the right option for your space.
Do I need a permit for a sauna in Newport Beach?
Indoor saunas need an electrical permit for the dedicated circuit and often a building permit for the framing. Outdoor builds need a building permit and possibly zoning review. Wood-burning heaters need a venting and combustion permit. We pull all of it.
What does a custom sauna cost?
Indoor conversions start in the mid-range; full custom outdoor cabins with premium heaters and glass walls are the top end. We give a flat-rate quote after the design phase — heater, wood, electrical, permits, and first heat-up included.
