Unwind Safely: Sauna Safety Tips and Maintenance Guide

Whether you’ve got a cube sauna nestled in your garden, or an infrared sauna in your living space, it’s important to keep you and your sauna safe and secure. We’ll take you through the basics of sauna safety, including maintenance advice and cleaning routines, so you can fully relax with peace of mind. Let’s get started.


Sauna health advice

1. Doctor’s orders 

First and foremost, before immersing yourself in the soothing world of a sauna, talk with your doctor. This is particularly important if you are pregnant, or have pre-existing health conditions like high blood pressure, skin issues and heart concerns. Your health should always be your top priority.

2. Hydrate to stay safe

Maintaining proper hydration is crucial. Make sure you drink plenty of water before and after your sauna session, to minimise risk of dehydration. Steer clear of drinks that include alcohol and caffeine, as they can exacerbate dehydration. Barrel saunas have built in exterior benches that make a perfect spot for a break and a drink. 

3. Short and sweet sessions

Gradual acclimatisation is key. Start with shorter sauna sessions, around 10-15 minutes, especially if you are new to saunas. Allow your body chance to adapt over time.

4. Cool down

After your sauna session, make time for a gradual cool-down. For every 15 minutes you spend in a sauna your body temperature rises 1.5c, so it’s important to spend as much time cooling down as you did in the sauna. A glass of water, gentle walk in the fresh air, and cool shower can help. If you’re feeling brave and want to really focus on your temperature tolerance, look into the benefits of an ice bath for cold water therapy


Hygienic haven in your sauna

1. It’s all in the prep

Proper hygiene allows for ultimate relaxation. Shower and wash your feet before you enter your sauna, and make sure you’re wearing clean clothes or swimsuits, and fresh bathrobes and towels. Cover the bench with your towel to create a barrier, and consider rugs, headrests and footrests to keep your sauna sparkling. Cure your sauna before you enter by letting it heat up for 45 minutes, then add some water to the rocks at the start of your session, to keep them clean and steamy. 

2. Keep it clean 

After your session, wipe down benches and surfaces to prevent the buildup of bacteria or mould. Use mild soap diluted with water, or sauna-friendly cleaning products that are suitable for wood. Once a month do a deep clean - sweep out any dirt, get in any nooks and crannies with a handheld hoover, and mop the floor, you may find a pressure washer on a low setting does the job. Make sure you do this when the sauna is turned off, as it’s dangerous to do strenuous cleaning in high temperatures and with exposure to heated chemicals. For stubborn stains that won’t budge, gently use a sandpaper on the wood.

3. Let it breathe

Ensure your sauna is ventilated during and after sauna sessions, which is easier to vent in an outdoor sauna than an sauja at home. After you’ve finished, open the door and vents while you wipe down the benches. Adequate ventilation not only improves air quality but also minimises mould within your sauna. A well vented sauna will feel warmer than a poorly vented one, as warm air easily circulates around the body. 

4. Wood maintenance

Wood in saunas, especially in gardens, requires regular inspection and treatment to prevent deterioration. This is crucial for preserving both the look of the wood and the structural integrity of the sauna. Towels and rugs will also prevent sweat from staining the wood. Use mild diluted soaps to keep the wood clean, and try not to use hard water if possible, which can cause lime buildup. Avoid using varnishes or paints in the interior, as the wood needs to absorb and release the moisture in your sauna. However, if you need to spruce up your garden sauna, use an oil on the exterior wood. 

5. Heater hygiene

If your home sauna uses an electric heater, meticulous attention to heater cleanliness is essential. Regularly check for dust buildup, as it can impact performance and pose a potential fire hazard. Check the sauna stones every month or so for signs of wear and tear, if you use your sauna a few times a week, the stones should last a year before they need replacing. 


Electrical sauna safety 

1. Inspect to protect

Periodically inspect wiring, outlets, and heating elements for any signs of wear or damage. Fix any issues as soon as possible to mitigate the risk of electrical hazards.

2. Expert installation

Ensure your sauna is installed by a qualified professional in adherence to safety standards. Proper grounding is critical to prevent electrical shocks and to ensure a safe sauna environment.

3. Manufacturer manuals 

Make sure you adhere to the manufacturer's guidelines for electrical usage. Avoid overloading circuits and using incompatible accessories, as this can compromise safety and performance.

Wood fire sauna safety

1. Ventilation vigilance

Proper ventilation through the chimney and vents is essential to release smoke and prevent the buildup of carbon monoxide. A wood burning sauna heater requires plenty of oxygen to keep it going. 

2. Dry wood

Opt for dry, seasoned wood exclusively for your sauna stove. This minimises the risk of excessive smoke, ensuring a safer and more enjoyable sauna experience.

3. Fire extinguisher

Keep a fire extinguisher within close reach. While the likelihood of a fire incident is small, having this safety measure readily available adds an extra layer of protection.

4. Chimney care 

Conduct regular inspections for any blockages or signs of wear. Making sure the chimney is in optimal condition not only makes it safer, but more efficient.

Sauna safety for the whole family

1. Childproofing

If your sauna is accessible to your kids, install safety locks to prevent them accessing it unsupervised.

2. Supervision

Always supervise children in and around the sauna area. Never allow unsupervised access, ensuring their safety and preventing accidents.

3. Pet protection 

If you have pets, do let them in your home sauna, and ensure they are not left unattended near it. The high temperatures can be harmful to them, and they may damage sauna components.

4. Educate your family 

Teach your family members, especially kids, about the importance of sauna safety. This includes following guidelines, sticking to time limits, and being careful in the sauna itself.

Sauna safety steps after a prolonged break

1. Rain check

If you have a barrel sauna, you’ll find it naturally sheds water and snow, but if you have a cube sauna, make sure you remove build up of snow and debris from the roof.

2. Inspect and clean

Before using your sauna after a long break, inspect the interior and exterior for any signs of damage or mould. Clean the surfaces thoroughly, ensuring a fresh and hygienic environment.

3. Heat gradually

Start with lower temperatures and shorter sessions, gradually increasing both as your body readjusts. This approach helps avoid intolerance and allows you to ease back into your sauna routine.

4. Check for pests

If your sauna is located outdoors, check for any signs of pest intrusions. Ensure there are no nests or damages that could compromise safety.
