Back in Ancient Roman, bathing played a major part in culture and society. However, It's a public activity. Not until 1883, American invented the world's first bathtub, since then, all kinds of bathtubs showed up in the market for people to choose and enjoy a hot bath at home!
How to buy a stone bathtub?
Among all those kinds and materials, the most popular contemporary freestanding bathtubs are made by natural stone, like marble, granite, sandstone, travertine, onyx; stone resin; cultured marble; concrete. In order to help you to choose the right one, here is the ultimate guide for the freestanding stone bathtub!
What is a Stone Bathtub?
A stone bathtub is hand-carved from a natural stone block. Technically, only a tub carved from natural stone is considered a “stone bathtub.” For example, artificial stone bathtubs, stone resin bathtubs, concrete bathtubs, and cultured marble bathtubs cannot actually be called “stone” bathtubs.
Common materials of a stone bathtub are marble, granite, sandstone, travertine, onyx, and quartz, among others. Stone bathtubs can add value to a house and provide an artistic display in the bathroom, and they are also easier to maintain.
What is an Artificial Stone Bathtub or Stone Resin Bathtub?
For long term use, an artificial stone bathtub is a better solution than an acrylic or fiber glass tub. The material of an artificial stone bathtub is a chemical blend of stone powder and acrylic.
Stone resin bathtubs (also called solid surface bathtubs) are made of man-made material including stone, minerals, and acrylic materials. They have the appearance of natural stone, but the wall of the bathtub is thinner than a real stone bathtub, which reduces heat retention. An important bathtub function.
Another difference is the availability of custom colours and non-porous surfaces, which gives stone resin baths brighter colours and greater durability, closer to that of a natural stone tub.
Stone Bathtubs Versus Artificial Stone Bathtubs
Stone bathtubs are bathtubs hand-carved from a natural stone block. Artificial stone bathtubs are made from acrylic, stone powder, and other such materials. Artificial stone bathtubs are made from a mold, so the size and shape are pre-designed; however, natural stone bathtubs are customized, which makes their sizes and shapes more flexible.
A natural stone bathtub is a far superior choice to an artificial stone tub. They can retain heat several times better than an artificial stone tub. Natural stone bathtubs also usually have thicker walls, meaning they are well insulated.
Finally, a stone bathtub can remain as lustrous and stunning as the day it was made for a longer period compared to an artificial stone bathtub.

What is a Concrete Bathtub?
For a contemporary bathroom, a concrete or freestanding stone bathtub is the essence of the design idea. You can't tell too much of a difference between a concrete bathtub and a honed surface natural stone bathtub: they look alike and they are both of the Zen style.
Both concrete bathtubs and honed surface stone bathtubs can provide decades of use both outdoors and indoors. However, their materials and functionality are different.
A stone bathtub is carved from a stone block, so it not only keeps heat longer, but it’s also easier to maintain. In contrast, the concrete can crack when exposed to changes in temperature, so this should be considered carefully before you make your decision.
As for prices, concrete bathtubs also charge a higher cost of labor, and the price range of a concrete bathtub is also higher than that of a stone bathtub.
What is a Cultured Marble Bathtub?
A cultured marble bathtub is a bathtub made of a blend of stone powder, stone particles, and resin. The cultured marble bathtub can have a wide range of colour and natural looking patterns, but unlike natural stone tubs, cultured marble are also cast in molds.
As a result, the final cultured marble bathtub is nonporous like a natural marble tub, and they are easy to clean or maintain.

What are Rose Quartz Bathtubs?
Rose quartz is found in abundance in many deposits throughout the world. Much of the rose quartz that is sold today is produced in Brazil, South Africa, India, and Madagascar. However, Rose quartz is commonly used for beads, jewelry, talismans, and other small decorations.
In Egyptian legend, rose quartz jewelry was used to maintain Isis's divine youth and beauty. Rose quartz was also used in ancient Tibetan and Chinese cultures as a token of love.

How to Make a Stone Bathtub
1) Choose your favorite color and shape from the catalogue, and then contact a stone expert to confirm the raw material of the tub. Commonly used materials include granite, marble, sandstone, travertine, and onyx.
2) After deciding which kind of stone to use, we will cut down a working size of a single stone block from local mine according to your dimensions, or import the stone block from other countries.
3) Transport the mined block to working factory.
4) Use a stone saw and various types of chisels, as well as hand tools, to shape the outside of the stone and hollow out the center of the tub.
5) Use grinders and orbital sanders to smooth out the tub after the shape has been formed.
Alcove Stone Bathtubs and Skirted Stone Bathtubs
An alcove bathtub is made to fit into a space surrounded by walls on three sides. Usually, a tub apron could be used in the front of the alcove to prevent water splashes, whereas a skirt bathtub will always have one completely open side.
Alcove bathtubs were designed to save space in the bathroom, so if you already have a limited space available, a square or rectangular alcove stone bathtub is the best choice. You could order any dimensions according to the size of your space.
For a stone skirted tub, there are more shape options available, including rounded or oval shapes, because the skirt covers the entire length of the bathtub. It's also easier to install.
Freestanding Stone Bathtub versus Granite Surrounding Bathtub
Freestanding bathtubs have been a popular trend in recent years, due to their compatibility with both contemporary or vintage bathroom designs.
In recent bathroom design trends, there is a tendency to leave more open space, specifically for people who want to enjoy a bath every day. Freestanding stone bathtubs are the best option for the center of a bathroom.
Not only does it look gorgeous, but it also adds value to the whole property.Additionally, a freestanding stone tub can fit any style, from classic clawfoot tub to a modern rectangular shape. It is a unique natural stone pattern for a bathroom decoration.
Granite bathtub surrounds were a common bathroom design in the 1980’s. Granite is a wonderful choice for a bathroom counters and tub surrounds thanks to its resistance to certain substances found in modern hygiene products.
Granite tub surrounds could provide more space for personal care items such as shampoo bottles. However, the design concept of a bathtub with a granite surround is outdated. If your bathroom has three available walls and an open space between, your better choice is a rectangular alcove stone bathtub, as opposed to a round tub with a square granite surround, which is more difficult to install.
What is the Difference Between a Soaking Tub and Regular Tub?

Other popular soaking tub designs include claw-foot, pedestal, high-backed, elongated, rectangular, etc.

- If you want to keep the polished surface shining even after a few years of use, a little protection from stains and etching such as spray sealant for granite or marble product could be used once a month.
- If stains and etching are left on the surface over the course of days, you can rub the stains with a soft cloth and marble polishing powder such as Miracle Sealants.
