Stone River Bathtub Outdoors - Tips & Tricks.

River stone bathtubs, also known as stone in its natural state, untouched by any craftsmanship or machinery, are perhaps the most popular stone bathtubs in the world. Their popularity stems from their uniqueness – each bathtub is different and one-of-a-kind. Even if you find a bathtub made from the same stone elsewhere, it will undoubtedly have a different shape, color, and size. Just as there are no two identical stones in a river, it is impossible to create two identical river stone bathtubs or stone sinks.

Their popularity, along with their resistance to weather conditions, chemicals, stone hardness, and relatively low cost, has led customers and architects to seek new uses for them. A few years ago, when they were only used in the bathrooms of individual apartments, they became increasingly popular in hotels and SPA and Wellness studios. Then, with the trend of smaller bathtubs, they were purchased for bedrooms or terraces. For the past three years, we have observed increased interest in orders for river stone bathtubs for outdoor use, whether the client intends to install them in very hot or very cold climates with snow and freezing temperatures.


What do you need to know to produce or purchase a river stone bathtub for outdoor use?

Certainly, not every manufacturer has the knowledge or experience regarding what happens to a bathtub after it is sold and used outdoors. If you want to use a river stone bathtub outdoors, because there are many advantages to this idea (more on that below), then marble bathtubs, onyx bathtubs, petrified wood bathtubs, and glued bathtubs – not made from a single block of stone – are definitely not suitable options. The only option left is river stone.

Outdoor Stone Bathtubs

River stone bathtubs for very hot climates.
If you plan to use a stone bathtub outdoors and live in a place where it gets very hot, such as Australia, Dubai, Greece, Portugal, Italy, or even Iran, Tunisia, Israel, Egypt, California, Texas, or any other extremely hot place on Earth, as some of our customers do who have had our bathtubs in such conditions for several years, you must inform the manufacturer about the installation location when making the purchase. In this case, you should receive a bathtub with stone that is devoid of veins. The manufacturer must be knowledgeable and able to distinguish veins from what is referred to as the “stone’s pattern” – only visual streaks and discolorations.

Deep veins in the stone, when the bathtub is heated to very high temperatures (in full, southern sun), create tension in the stone, especially with such a large volume and mass, and can lead to cracks in the bathtub! A deep vein causes the bathtub to crack along the entire length of the vein (see the example below – a bathtub made by inexperienced individuals). The stone bathtub manufacturer should consider that stone easily absorbs ambient temperature, accumulates it, and slowly releases it. If the bathtub is left in full sun for many days and the stone’s structure is not well-suited, it will crack. We are more than confident about this.

✓ Additional advice from us:
If you have an outdoor stone bathtub in a very hot climate, make sure there is always a small amount of water at the bottom. Water will absorb the stress on the stone, absorb some of the temperature, and allow the stone to work completely differently. Nothing more is needed.

Top 3 benefits of having a river stone bathtub outdoors in very hot climates.

  • Pour very cold water just before taking a bath or soaking. The water will increase its temperature by absorbing it from the heated bathtub, maintaining that temperature for a long, relaxing soak, whether at noon or in the evening, at a pleasant temperature lower than the surroundings.
  • A stone bathtub outdoors is much cheaper than a pool, easier to maintain, trouble-free, more enjoyable, and provides much more relaxation. While lying in such a bathtub, you feel the naturalness of the stone, you can enjoy the view, read, listen to music, or simply do nothing. This is impossible in a pool.
    • Your natural stone bathtub will be an exceptional decorative element for your terrace or garden. Some of our customers also use standing river stone sinks.

Outdoor Stone Sinks


River stone bathtubs for very cold climates

If your investment is in a location where there is a season with a lot of snow and freezing temperatures, such as Canada, Norway, Alaska, Austria, Switzerland, New York, like many of our customers, inform the manufacturer of your idea. The stone used for your bathtub must be free from microcracks, microfissures. Extracting such stone for your bathtub must be free from shocks and impacts that can cause internal cracks or delamination of the stone. If your bathtub even has the smallest cracks, after installation in a cold environment, it will stop being watertight and start to leak. This is because water, even in the form of moisture during freezing, expands its volume. When it turns into ice, it cracks the microcracks in the stone, causing larger gaps over time, which eventually causes the bathtub to leak and become unusable. A stone bathtub manufacturer for such a location must be absolutely certain that the stone used for production has not experienced shocks that could cause internal cracks.

We once received an order from an investor who asked us to cut longitudinal grooves on the bottom of the bathtub because he wanted to place a type of underfloor heating, which was connected to the home’s heating system, in the bathtub’s base. This was four years ago, and it still functions today.



✓ Additional advice from us:

  • If you have a stone bathtub outdoors in a very cold climate, use it more than once a week if possible or apply stone impregnation every two months (simply wipe the inner surface with a cloth soaked in stone impregnation). Nothing more is needed.

Top 2 benefits of having a river stone bathtub outdoors in a cold climate.

  • Fill the bathtub halfway with warm water even in freezing temperatures, drain it, and fill it again with warmer water. Enjoy the cold surroundings while relaxing in a warm environment, just like in hot springs. Remember that natural stone easily absorbs temperature and slowly releases it.
  • You have your private hot springs whenever you want. The temperature of the water in the bathtub in freezing weather depends only on you. You can pour warm water halfway two or three times and release it before refilling it with water for use to achieve an even higher temperature.

Boulder Stone Bathtubs

Natural Stone Bathtubs - Bedroom

A real natural stone bathtub in the bedroom. 

A real stone bathtub in the bedroom.

Trends are changing. From ideas of a bathtub only in the bathroom, designs are beginning to evolve toward convenience and bringing nature into new places. Increasingly, an additional bathtub is beginning to appear in the bedroom. Why? Customers answer, because convenient, because interesting, because it changes the atmosphere of the bedroom.

Natural Stone Bathtub - Bedroom


Until now, we have been used to having our river stone bathtubs installed in bathrooms, spas or gardens. This time we received photos from customers who installed their huge bathtub (length of more than 240 cm) in the bedroom, opposite the bed. They gained something special, a natural boulder of stone with irregular shapes catches the eye more than a TV, is addictive and introduces something unique to the interior, which can not be duplicated. This is how a private spa was created in one’s own apartment. Enjoying a bath with the touch of natural rock and atmospheric interior gives a feeling of deep relaxation, relaxation whether it is evening or morning.

How to install such a stone bathtub in the bedroom?
In this case, the installation of the bathtub, despite the fact that the bedroom is on the first level, was very simple. An HDS-type car jack was used, which with its boom inserted the bathtub through the balcony window into the bedroom. In other cases, customers used forklifts, pallet trucks or simply moving companies, which, using belts and 9-10 workers, brought and set up such a bathtub in the designed place.

TOP 3 perks of a natural stone bathtub in a private spa.

Advantage 1 Temperature. Natural stone easily absorbs temperature and gives it back for a very long time. In hot weather, filling the tub with very cold water will make relaxation and cooling of the body a pleasure that can not be replaced by air conditioning, and the body will certainly thank us for it. This combination is probably most often used in river stone tubs inserted from the garden. On hot days they replace swimming pools and soaking in the cool water outside is comparable only to a mountain stream.
On the other hand, when cold days come and we crave warmth, pouring hot water into such a tub is comparable to heated massage stones. They stay warm for several more hours after heating.

Natural Stone Bathtub - Bedroom

Advantage 2. The naturalness of the stone in contact with human skin can be felt. Each person perceives this feeling in a different way, but for everyone the touch of the stone is very pleasant. This affects the feeling of our relaxation, comfort and pleasure.

Natural Stone Bathtub - Bedroom

Advantage 3. unique bedroom interior and furnishings that will stay forever. There is probably no interior where once inserted natural stone succumbs to the pressure of time. Stone is so addictive that it stays forever. Furniture, floors or walls are changed but the bathtub or sink made of natural stone already remains.

Probably the largest stone bathtub

The biggest stone bathtub

Probably the largest stone bathtub 

Probably the largest stone bathtub in the world.

Producing river stone bathtubs is certainly a demanding job involving many teams. It all starts with finding the right boulder in an Indonesian river. The task is not easy, as the selected huge pebble is compressed with other stones. In addition, no one has any idea what the shape of the underwater rock is. With each boulder weighing more than 500 kg and the risk of not getting the shape you need after excavating the stone, it sometimes takes days spent searching for and extracting the right rock.

Just getting the material out of the water for the bathtub is the work of many people, a great deal of experience and skill in using simple equipment that can be used in a rushing river.

We managed to obtain a huge boulder as long as 350 cm, extracted it from the river and transported it to the factory. Then, we carefully cut off the top part of this stone and the craftsmen proceeded to excavate the bath by hand. For the first time, we obtained a huge bathing space that holds more than 700 litres of water! The final weight of this bathtub is almost 3 tonnes and packing it into a wooden box required a huge undertaking on the part of our people. The width of the shipping container is 2.35 m. In that case, packing the bathtub in width was impossible, at the same time, inserting it lengthwise required the use of custom forklifts during loading and unpacking at the customer’s site in the USA.

This is the first realisation of this kind of river stone bathtub with such a large mass. Until now, we have realised bathtubs of twin shape and size (2 bathtubs cut from one piece of rock in the middle), round stone bathtubs or a bathtub and basin that was one rock before being cut.


We are writing about this because we want to showcase our capabilities. We manufacture natural stone bathtubs according to the expectations of our customers, and if time allows, we are able to fulfill most of our customers’ special orders. We always precede production with preliminary consultations and explanation of all the possibilities and limitations associated with manufacturing stone bathtubs.

Our customers include hotel resorts, private investors, local importers and distributors, and interior designers. We collaborate with companies that are capable of delivering any bathtub to any location on Earth.

Petrified Wood Bathtubs are one of the rarest of their kind

Petrified Wood Bathtub

Amazing Petrified Wood Bathtubs  are one of the rarest of their kind

Amazing Petrified Wood Bathtubs are one of the rarest of their kind

Typical human lifespan is 79 years. It is much too short not to try, at least once, taking a bath in a Fossil Wood Bathtub that ages at least a few millions of years.

Petrified Wood?
Yes indeed. In other words, a tree that spent so much time in the volacanic ashes of Indonesia that it simply decided to turn into stone. Well, it wasn’t really that tree who decided that, as instead it was mother nature in the flesh. That is why we trust her decisions and would like to show you a gift from her which we carefully honed.

Fossil Wood Bathtub LIGNUM is made only from that million-years-old tree log. Therefore, it does not need much treatment. Having survived millions of years underground, who would need it?
The bathtub is manually polished, with no use of toxic or harmful materials. It is quite heavy, usually it weights up to a ton, but that’s the least of our worries. It is rare and, therefore, quite expensive..

A standard model costs over 35 thousands of US dollars. It is the price of having something only a few people on earth have, so we believe it is well worth it. Especially considering that one day we will simply run out of this extraordinary material. Just look at the direction that humanity is following – abandon fossil fuels! Quite right, though.

If you don’t feel like spending tens of thousands of dollars on the stone bathubs? No worries! We’ve all been there. There is an equally beautiful alternative, namely, River Stone Bathtub Flumen, our undeniable best-seller. It costs over ten times less than a standard Petrified Wood Bathtub, so you don’t really need to inherit a fortune in order to become a stone tub lover.

I thought not.
However, if any appear, don’t hestiate to use the contact form below. Charge yourself with Zen energy, either in a River Stone Tub or Petrified Wood Bathtub.
If you are still not fully convinced, below gallery will fix that.
