History of use

Which stone should not be used in a bath?

You need to be especially careful when choosing stones. Ordinary river stones or those simply found near the site are not suitable for a home bath. The bath uses special minerals that do not emit harmful substances when heated. When purchasing stones, it is important to pay attention to the label “the product has passed radiation control.”Stones should:1) withstand temperature changes. Heat them and throw them into cold water: high-quality stones should not split or crack;2) keep warm for a long time.
Heavy, dense stones with a uniform structure retain heat best;3) match the type of oven.
Large stones (up to 130 mm) are suitable for wood-burning heaters. For electric ones – smaller stones (up to 60 mm in diameter).Selecting the type of stone.
Stones differ not only in their service life, but also in price, as well as physical and healing properties. It is important to choose exactly the stones that are right for you.Pebbles (sea and river).The most economical option. Pebbles are quite strong and durable, and the main thing is that you don’t have to buy them, but find them in the river near your house. It is important to select the stones correctly: the shape should not be round, but flattened. It will fill the heater more tightly and protect metal parts from accidental ingress of water.
Avoid soft stones – limestone has a detrimental effect on the body and quickly breaks down.
There should be no red veins in the structure of the stone – it is iron. When heated, it will oxidize, which can be harmful to health.Gabbro-diabase.The most popular option. It is mined here in Karelia. It is of volcanic origin. Its undoubted advantages are low price and high strength. It does not absorb moisture and heats up evenly. But there are also significant disadvantages: it cools quickly, emits an unpleasant odor, it cannot be used with essential oils (as carbon deposits appear), and stones spoiled by temperature can clog the oven.Talcochlorite.It is often used for lining stoves. More dense and durable, unlike gabbro-diabase. It heats up quickly, retains heat well and distributes heat evenly, and does not emit harmful substances when heated. Contact with water creates a light, pleasant steam. To prevent the stones from falling off, they must first be calcined, and then the soapstone will serve you for many years.Basalt (volcanic rock).Environmentally friendly, black stone has high strength and heat capacity. Almost does not absorb moisture and is resistant to temperature changes. With its help, powerful, persistent steam is produced.Jade.A semi-precious stone with a luxurious emerald hue. Meets all requirements, functional and attractive. Will decorate any sauna with its appearance. It is 3 times stronger than other rocks and also has excellent heat capacity. The downside is the high price.Raspberry quartzite.A sharp purple mineral will add an original accent to the design of the steam room.
Resistant to cracking. Durable, durable, does not emit harmful impurities.White quartz.One of the most expensive minerals. A beautiful, environmentally friendly, translucent mineral. Outwardly impressive, it’s not for nothing that they call it “hot ice.” Consists of silicon and oxygen. Unfortunately, critical temperatures will cause it to crack and burst.You can choose stones based on your budget, type of stove, healing properties and steam room design. Once every five years, for variety, you can change the type of stone.

When building a bathhouse, quite little attention is paid to the stones in the stove. But stones are what we get steam from, they accumulate the thermal energy of wood combustion and then transfer it to us. We have prepared for you the top 5 types of stones for baths in different price segments. You definitely won’t regret using these stones. Jade – metamorphic rock, mineral, color from light green to dark green, granular structure. One of the most popular, but expensive bath stones.


Jadeite is based on a simple aluminosilicate – silica and aluminum oxide, plus sodium oxide. Jadeite belongs to the pyroxene-hornblendite family. Most pyroxenes are monomineral, that is, these rocks consist predominantly of only one mineral, i.e. jadeite – from jadeite.


This popularity of the stone is due to its high density and heat capacity. Withstands high temperatures and does not react with water, as it is chemically inert. Doesn’t crumble when temperature changes. It is important that using it in a bathhouse will not cause any harm: it does not contain any poisonous, foul-smelling, or radioactive impurities. Despite its high cost, this stone will serve you for a long time. Medical studies have shown that using jadeite in a bathhouse has a beneficial effect on human health. The breed is capable of: improving blood composition, kidney function, bronchial function, treating the spine, and normalizing blood pressure. The beneficial microelements released by the stone saturate the body and improve the condition of the body.


The only disadvantages are, perhaps, the rarity and price of the stone; it does no harm.

In general, this is a stone that will last for many years and is worth investing in.

Dunit — a confident average among sauna stones. An igneous rock that is used in some countries as a fireproof material. Color from black to green. The structure of dunite is either fine or medium-grained. The cost of the stone is not too high. Composition: The chemical composition is dominated by magnesium silicate. 90% consists of olivine, also known as chrysolite, with an admixture of chromite. Types of dunite:


It has high density and good heat capacity. This stone will not crack over time and will allow you to heat the steam room quickly and efficiently. Well, and what is also important, this stone is beautiful, especially when wet. Due to this, your bathhouse will look more advantageous.

By interacting with steam, dunite disinfects the air and kills microbes located on the skin and in the human body. Dunite helps to: normalize blood pressure, heart function, improve vision, and is also excellent for the prevention and treatment of colds.

The disadvantages of dunite include possible impurities of sulfides, which under the influence of high temperatures turn into oxides and cause an unpleasant odor, as well as soreness and cough.

Mountain, environmentally friendly – one of the best options for your bathhouse.

Raspberry quartzite – metamorphic rock, hard and dense, color – crimson-red.

Contains up to 98% quartz, the rest is iron oxides and hydroxides. The rock contains inclusions of mica, chalcedony and silicon.

The stone is very popular in the bath industry; it has good strength, significant heat capacity and a fairly high density, due to which it creates a soft, pleasant steam. Fire resistance up to 1770 °C, tolerates temperature changes well and does not collapse or lose properties. Does not emit harmful substances.

According to doctors, the use of this stone in the bath is of great value for the body. Raspberry quartzite is able to: normalize blood pressure, improve blood composition and circulation, eliminate ailments and pain in the lumbar region, muscles and joints, strengthen the immune system.

The disadvantages of quartzite include the fact that due to cracks acquired after the crusher, the stones can be destroyed in a sauna stove.

There is a reason why this stone enjoys its popularity – it is durable, resistant to moisture and high temperatures and very beautiful, which means it is perfect for a bathhouse.

Porphyrite — Igneous, fine-grained rock, cameo color is dark gray and dark green.

The composition of porphyrite is not very different from jadeite – the same silica, the same metal oxides.

Most often, the mineral components of porphyrite are as follows:

  • Hornblende
  • Plagioclase
  • Pyroxene

Fireproof, not afraid of temperature changes. One of the unique properties of the stone is its ability to self-clean. Does not crack or collapse for many years. Porphyrite helps restore the cardiovascular and respiratory systems, it also helps with migraines and skin rashes, normalizes blood pressure, and is effective in treating respiratory diseases.

The disadvantages of this stone, just like in the case of dunite, are the possible presence of sulfides.

In general, this is the best option for use in a bathhouse. The stone is suitable and inexpensive.

Gabbro-diabase – volcanic, fine-grained rock, similar to marble or granite, uniformly dark in color, cheap and popular stone.

Approximately 50% consists of silica, the rest is metal oxides.

The mineral composition is mainly represented by plagioclase, pyroxenes, olivine and titanium magnetite.

It has high density, strength and low water absorption. When heated, gabbro-diabase expands evenly. Just like jadeite, it is chemically inert and does not react with water and oxygen, therefore it is safe.

The stone can reduce nervousness and has a positive effect on the performance of the kidneys, genitourinary function and liver.

The disadvantages are the possible presence of sulfides, short-lived, with an average service life of 2-3 years.

The most budget-friendly, but very worthy option for your bathhouse.

The steam room and heater require special attention, because the softness of the steam and the healing effect depend on the type and quality of the stone. Choosing stones is a difficult but interesting process, so we suggest you choose the stone whose properties seem most important to you for a pleasant and useful holiday.
