You will find the coolest part of your sauna is the sauna floor. It is important that you do not allow this to cause any heat loss or bad insulation. You will need to have a heatproof floor. There are several different types of floors that can do this for you. You also want to make sure the floor you choose does not become too hot and burns the bottoms of your feet.
When you are choosing a room to build in a sauna, you should consider using a smaller room so that the heat is distributed properly. As long as you can lay down and sit comfortably on every bench, you have the ideal room size.
Avoid rooms with high ceilings, as heat rises, leaving the bottom bench chilly and wasting the heating by having to fill a high ceiling room.
One thing you also need to be aware of is how the sauna door is going to swing. You want enough room for the door to swing out, not into the sauna. Being whacked on the elbow or knee by an inward swinging door defeats the purpose of relaxing in a sauna.Check out our range of Portable Sauna Melbourne to help with your problem.
Are you planning a Sauna in your house, garden house or garden? The selection of saunas is numerous as well as varied. Does this also apply in detail to Sauna Floors: Wood? Tiles? PVC? Laminate? We explain which Sauna Floors has what it takes to serve you well in the sauna and you learn what requirements a Sauna must meet – and how the different Sauna Floors succeed.
The bar for materials that you use as Floors in a Sauna is high: because the typical climate in the sauna is warm to hot and dry to steamy wet, depending on the sauna. The climate is constantly changing: In operation, the sauna is heated, out of operation, it remains cool. In operation, it is dry to steam-soaked, while out of operation the humidity depends on the location of the sauna and thus on the environment.
However, it is not only the sauna that is affecting the Sauna: Hygiene, cleaning and safety and security (keywords: non-slip and fireproof) also set standards for the Floors in the sauna. Likewise, the sauna or the heating technology it embodies can be decisive in choosing the right sauna.
Concrete is always the best option for a sauna floor. You will need to make sure it has a sealer applied to it, so it is waterproof. You can then finish it with ceramic tile. The tile can handle the heat of the sauna without causing you to be uncomfortable walking on it. But you will need to use caution because tile can become slippery when damp. Walk slowly and make sure the bottoms of your feet are completely dry before you walk on the tile. Because this sauna floor can be a little bit expensive, it is not always the first choice.
If you happen to have vinyl tiles in your sauna, they can also withstand the heat and humidity. Although they are cheaper initially, they are not as durable. You will need to replace vinyl more often than ceramic tiles.
If you are working with plywood floors, make sure they are properly sealed. You will want to seal all of the joints properly with wood preservative. Apply multiple coats to make sure the wood is protected. Plywood floors can have a lot of issues with the sauna’s heat and humidity if you don’t properly protect the wood.
There are several different types of adhesives you will need to use so the wood floor in your sauna can be completely waterproof. You can use ceramic tiles or seamless sheets of vinyl or fibreglass to waterproof your wood floors. The adhesives will still be necessary, though.
Know Your Flooring Material Options
The perfect flooring for saunas, spas, steam rooms, and showers must meet four criteria. It must be nonporous, nonabsorbent, slip-resistant and offer a quick return to service. It helps if the flooring is also attractive.
Slate, marble, and limestone are alluring. However, they are porous materials that require re-sealing every few months when used in a hot and moist environment. They are also not as slip-resistant as other materials.
Wood or wood slates are often used in saunas, spas, and steam rooms, but wood products are porous and absorbent, creating a super breeding ground for bacteria and mould. Industry experts recommend thoroughly hosing and scrubbing once a week, including the lighting fixtures if the wood is used in hot and moist environments.
Tiles can be manufactured to be nonporous and nonabsorbent, as well as slip-resistant. The problem is the grout between. The grout has none of the characteristics of the tile and harbours bacteria, mould, and other microorganisms.
Concrete with a polyurea coating emerges as the solution that meets all four criteria:
- It creates nonporous, nonabsorbent flooring in saunas, spas, steam rooms, and wet rooms.
- Anti-slip aggregates can be mixed into the coating to increase the slip resistance.
- Additionally, colour coatings and decorative chips are also available, for aesthetically pleasing results.
- It offers a quick return to service in hours, not days as it takes for epoxy systems.
The Advantages of Polyurea Floor Coatings
Polyurea floor coatings have a higher resistance to chemicals and abrasion than epoxy, which means that polyurea will stand up better under repeated use and cleaning. It is also more resistant to yellowing under natural light – so when your client installs a window or skylight in the bathroom or spa, the flooring will stay clear over time.
When compared to polyurethane floor coating, polyurea still gives all the advantages above, plus it creates a much stronger, permanent bond to concrete and has the lowest volatile organic compounds (VOCs).
Finally, polyurea floor coatings are more resistant to the swings in temperature and humidity characteristic of saunas, spas, steam rooms, and wet rooms.
Sauna: Which Floors is most popular?
As announced at the beginning, we would like to introduce you to the common Sauna Floors, which have proven their worth in practice.
Sauna Wood: The Classic
Wood is a natural, renewable material which, with its typical wood colours, creates a visually warm atmosphere in the sauna. But not only that: wood also absorbs heat well, stores it and radiates it again. The low thermal conductivity of wood is a good match for you in the sauna because wood does not get too hot even in a very hot Sauna. So you don’t burn your feet on a wooden floor! And the danger of slipping is also rather small with wooden flooring. Looking for Sauna Melbourne? Look no further, Portable Sauna has you covered
But wood is more susceptible to dirt than the following Sauna Floors made of stone or ceramic. Besides, he cares more about humidity than that. Therefore, wood should be able to dry properly after each operation to prevent permanent damage. In principle, however, wood is a widespread building material for the design of the interior cabin of saunas, whereby you should always resort to types of wood that neither resin nor splinter. In short: wood is just as good for Sauna Floors as it is for walls or ceilings.
Our tip: Just make sure that you do not lay any wood on the sauna where the sauna is, as wood is not fireproof. And if splinters of heated sauna fall off, they leave ugly traces of fire on the wooden floor.
Laminate is also commonly used as a wooden floor covering in saunas, although there is a special damp-proof laminate that meets the requirements of saunas well. At best, it does not swell as quickly as laminate and does not emit any harmful vapours when exposed to heat.
Stone as Sauna Floors
A stone floor is not affected by heat or moisture – with the exception of marble.
This absorbs some water and also becomes more easily dirty. And cleaning the marble is expensive. A Sauna made of natural stone is extremely robust and can also be designed in such a way that it is non-slip. And optically nature always scores points, because it is always unique. After all, no stone is like the other. Caution is advised, as stones can become very hot.
Our tip: Sometimes the stone is said to have a cool appearance, but you can consciously counteract this effect with stones in warm colours.
Tiles as Sauna
Ceramic tiles are also a classic: Even saunas in ancient Rome have been lined with fired and glazed clay tiles. Until today the tiled floor is very popular because of its robustness and easy cleaning. There have long been tiles with high slip resistance. A prerequisite for the optimal laying of the tiles is that the substrate is flat. Important: Tiles can get very hot, but it is always coolest on the Floors of the Sauna.
Our tip: A tiled Floors or even a completely tiled Sauna quickly looks cool and not very inviting, especially if the tiles are white. So rather choose ceramic tiles in warm tones.
Sauna: Wood or tiles?
The question of whether you buy wood or tiles as a sauna can only be decided individually by looking at the advantages and disadvantages of both materials and setting your priorities.
You should be aware that both materials are often combined: A Floors covered with tiles or stone is then given a so-called Wood walking or standing surface, which can be easily removed to clean tiles or stones underneath.
Cork as Sauna Floors
Similar to wood, cork also scores with its naturally grown structure as a Sauna. It is soft, sometimes also too soft, in appearance, warm and non-slip.
Similar to wood, a cork floor does not like too much moisture, so it must be given the opportunity to dry well after sauna. When it comes to fire protection, the same applies to cork as to the wood.
Coating as sauna floor covering
This is currently the trend: a coating as a Sauna. For this purpose, so-called epoxy resin is applied to the concrete floor of the sauna, which then hardens and seals the Floors watertight. Such a coated Sauna is mirror-smooth, sometimes even too smooth.
The smooth surface makes the coating very Care. To roughen the coating, you can sprinkle in special flakes that also look a bit more attractive. However, if the Floors becomes damp, it is often still dangerously slippery. You must also know that the hard resin layer is also brittle. If something falls on the coated sauna, a part of it sometimes bursts away. In the worst case, the resin layer is tight at the point of impact and water penetrates downwards.
PVC as Sauna Floors
PVC Floors is another trend that does not stop at the sauna.
The reason for the renewed love for PVC flooring is that the market now offers a wide range of different optics so that the positive material properties of PVC (easy installation and Care, robustness, water resistance, slip resistance) are compatible with attractive stone or wood optics.
Stone carpet as Sauna Floors
A stone carpet is a Floors for which pebbles or other stones are applied to the sauna with epoxy or polyurethane (PUR). Typical are the pebbly surface and the massaging, pleasant appearance. Thanks to the air trapped in the coating, the stone carpet also treads warm. The pebbly surface absorbs dust quite deeply, which is then also less stirred up and can also be easily vacuumed away with a suitable vacuum cleaner – provided the dust is dry.
Our tip: A water vacuum cleaner or steam cleaner is recommended for intensive cleaning of a stone carpet. At the same time, wet/dry vacuum cleaners are not recommended as they leave too much moisture behind.
Sauna Construction Details Often Overlooked
Over the years, we have found many mistakes made by amateurs during the sauna construction process. We want to save you some hassle by providing these quick tips for maximum safety and comfort. Also Portable Sauna Melbourne page which has everything Portable Sauna related that you might need
Clearances to Combustibles
There are minimum clearances from combustibles for the sauna heaters. Always follow the manufacturer’s recommended clearances. For wood-burning sauna heaters, you may also require a WETT inspection to satisfy your insurance company.
Sauna Door Swing
For safety reasons, a sauna door should always swing out of the sauna, allowing quick escape should an emergency arise. Becoming trapped could prove fatal if escape delayed.
Saunas with heavy traffic should have a window in the door to avoid bumping the door into someone behind it.
Air Circulation and Venting
A moist, warm sauna can be a breeding ground for unwanted mould if proper precautions are not taken into consideration. Following a sauna session, the sauna needs to be quickly aired out and dried to eliminate mould potential. Installing a vent or window that can be opened post-sauna would be ideal to allow moisture to escape and allow fresh air movement. If no vent is possible, then leaving the door ajar post-sauna will help.
Often saunas are oversized needing extra energy to heat. Consider how many people would use it at one time and adjust sizing accordingly. To save on cubic space but maximize on seating, consider L-shaped or U-shaped benches in your design. If the sauna has a wood-burning heater, also consider the clearances required from the heater to the benches.
Water and sweat eventually stain the wood leaving ugly wear marks on benches and walls. While some of it can be sanded to bare wood to refresh, deeper stains are difficult to remove. Also sanding is a messy and tedious process. The wood inside the sauna should be preserved, but not with varnish, lacquer or paint. These finishes can off-gas toxic fumes in the heat and also could make the surfaces uncomfortably hot. The best option is a water-based natural sauna sealer which dries clear. It will seal the pores of the wood and keep it from staining and going grey, keeping your sauna looking like new.
Improper drainage leaves pooling water and moisture to linger, causing potential mould problems. The sauna floor should contain a drain with the floor slightly sloped towards the drain to remove excess moisture quickly. The floor should be finished with a waterproof, easy to clean surface to make maintenance a breeze. Cement floors are cold on the feet and a dirt trap if not finished well. Tile is better but still cool on the feet, with grout lines to maintain. An epoxy paint system is the easiest to clean and can be applied on a wooden sub-floor. Wooden slat mats, called duckboards, can be used where feet touch the floor for added comfort on cold floors. However, they need to be lifted on edge to air dry post-sauna.
The consistent levels of high humidity and fluctuating temperatures found in spas and saunas place unique demands on the materials used in the construction of these types of facilities. Wet rooms are also increasing in popularity, both in private residences and facilities such as high-end gyms, hotels, and spas. A wet room is a type of bathroom where the shower, instead of being a separated element, uses a floor that is flush with that of the rest of the bathroom and is separated by a single wall or panel. These designs typically include a drain set close to the middle of the wet room, with the floors gently sloping towards it to facilitate drainage.
