ASL
A home sauna, a garage gym or a dedicated workout room needs more than an extra outlet. Sauna heaters, treadmills and other equipment draw serious power, and many need a dedicated 240V or 120V circuit sized to the manufacturer's specifications. ASL Electric wires saunas, home gyms and fitness rooms across Orange County, with the right circuits, lighting and ventilation power so everything runs safely.
Before you buy equipment, or as soon as you have, send us the model numbers. We check the electrical requirements against your panel, run a load calculation and plan the circuits, so your sauna or treadmill does not trip a breaker the first time you use it. Then we install, permit and test everything.

When to call us
Homeowners usually call when:
- You are buying a sauna and need to know the circuit requirements
- A treadmill trips the breaker when it starts
- Your garage gym runs on extension cords
- You are converting a room or garage into a gym
- An outdoor sauna needs power run to the yard
- Your panel may be close to full
- You want better lighting and ventilation
- You want a timer or smart control on the sauna
Why the right circuit matters
Sauna heaters are high-heat, high-load appliances that run for long periods. Treadmill motors draw a surge when they start. On a shared or undersized circuit, both can trip breakers, overheat connections or damage equipment, and an improper installation can void the manufacturer's warranty. A dedicated circuit sized to the manufacturer's requirements is the safe and reliable answer.
How we wire a sauna or gym
Check the specifications
We review the equipment's installation manual for voltage, amperage, wire type and connection requirements.
Load calculation
We confirm your panel and service can support the new loads, and plan a subpanel or upgrade if needed.
Install and connect
We run the circuits, install the outlets or hardwired connections, and add lighting and controls.
Permit and test
We pull the permit, test under load and walk you through the controls.
Indoor, outdoor and infrared saunas
Traditional sauna heaters usually need a 240V circuit, while some smaller infrared units run on 120V. Outdoor barrel and cabin saunas also need power run from the house, usually in buried conduit to a disconnect near the sauna.
The manufacturer specifies the circuit size and connection type. We follow it exactly, along with the California Electrical Code, so the sauna performs as designed and the warranty stays valid.
Planning a garage gym
A garage gym usually needs a few things the original garage wiring was not designed for: more outlets on separate circuits, bright, even lighting, and sometimes a 240V circuit for commercial-grade equipment. If you are also planning an EV charger or workshop tools, we plan all the garage loads together. See our garage electrical page.
What affects the cost
The main factors are the equipment's electrical requirements, the distance from the panel, whether the sauna is indoors or outdoors, trenching for outdoor runs, panel capacity, lighting and controls, and permit requirements. We give you a free, upfront estimate.

Sauna & Home Gym Electrical across Orange County
Home saunas and garage gyms have become common projects across Orange County. We wire them in single-family homes in Irvine, Ladera Ranch, Coto de Caza, Newport Beach and Laguna Niguel, and in garages in Lake Forest, Mission Viejo and Huntington Beach. Outdoor saunas on hillside and coastal lots often need longer runs and careful conduit routing.
If your panel is near capacity, we will tell you before you buy, so the project fits your home.
