Sauna Electrical Requirements: Everything You Need to Know

Installing a sauna at home is a fantastic way to unwind, alleviate stress, and boost your overall health. However, it's crucial to understand the specific electrical and plumbing requirements to ensure your sauna is safe and functions effectively. This guide aims to equip you with all the necessary information on these requirements.

Sauna Electrical Wiring

Electrical Wiring

For your sauna's electrical wiring, hiring a licensed electrician is mandatory. The wiring needs to be suitable for high temperatures and moisture, and it's advisable to run it through a conduit for protection against moisture and damage. Ensure the wiring layout facilitates straightforward maintenance and repairs.

Circuit Breakers

A dedicated circuit breaker is essential for your sauna, with its size tailored to your sauna's needs. Clearly label this circuit breaker for easy identification and place it close to the sauna for convenience.

Voltage Requirements

Depending on the make of your sauna, you might need a 120-volt or 240-volt power supply. Refer to the manufacturer's guide for specific voltage requirements. A 240-volt sauna necessitates a dedicated circuit equipped with a double-pole breaker.

Electrical Box and Disconnect Switch

Compliance with code requirements is crucial for your sauna's electrical box, which should be positioned near the sauna and clearly marked. Additionally, a disconnect switch is required to safely power down the sauna for any maintenance or repairs.

Lighting Requirements

The sauna's lighting must comply with safety codes, be suitable for high temperatures and moisture, and be placed to ensure the sauna is well-lit while also being accessible for maintenance and repairs.

Sauna Plumbing

Sauna Plumbing Requirements

Water Supply

If your sauna uses steam, a licensed plumber should install a water supply line complete with a shutoff valve and a backflow preventer to maintain water quality.


A drain may be necessary to handle excess water, designed for easy maintenance and equipped with a trap to block unwanted odors.


Proper ventilation is crucial to remove moisture and supply fresh air. Ensure the ventilation system is easily accessible for upkeep, and includes a fan and a vent cap to block pests.


Meeting the electrical and plumbing requirements is vital for a safe and efficient sauna experience. These include specific needs for electrical wiring, circuit breakers, voltage, electrical boxes, disconnect switches, lighting, water supply, drainage, and ventilation. Engaging licensed professionals and adhering to code requirements will help secure the safety and effectiveness of your sauna.
