Standard bathtubs are made from enamel-coated ferrous metal or acrylic, but industrial developments have led to the creation of new materials. A cast marble bathtub has pros and cons that should be taken into account when choosing and installing equipment. The artificial material has an original appearance, but does not tolerate mechanical stress and is destroyed by sudden temperature changes.
What is cast marble
Artificial stone is crushed marble with the addition of quartz sand mixed with synthetic resin. The standard allows the introduction of a binder within 20% of the total volume of the material: a decrease in the amount of stone chips leads to a deterioration in performance characteristics. The resulting raw materials are poured into molds previously coated with a protective substance.
After crystallization, a transparent film remains on the surface of the artificial stone product, preventing damage to the material during operation.
Material characteristics
Due to the combination of natural minerals and synthetic resins, the material has increased abrasion resistance and can withstand short-term heating up to +900°C (an irreversible change in shade is possible). The structure of the material does not absorb moisture and organic solvents; household cleaning agents do not have a negative effect on cast marble. Density ranges from 1.8 to 2.2 g/cm³ (depending on the characteristics of the raw materials), which is 15-20% lower than the specific gravity of natural stone.
Main parameters:
- compressive strength - from 70 to 120 MPa;
- abrasion coefficient - 0.44 g/cm³;
- permissible static load - 350 kg;
- moisture absorption coefficient - less than 1%;
- frost resistance - up to 300 cycles.
Width of color palette
The color of the material is determined by the pigment that is introduced when mixing the components. Manufacturers produce material in various color shades, which allows you to select sanitary equipment taking into account the design of the bathroom. The introduction of several pigments ensures the production of an original ornament with shade transitions in a random sequence.
Mechanical engraving with filling of the grooves with contrasting paint (for example, gold or silver) is allowed.
Material advantages
Advantages of cast marble plumbing products:
- increased sound insulation does not require additional protection to be applied to the outer part of the bathtub;
- artificial stone does not conduct electricity;
- the product allows for refurbishment;
- the material has a uniform color.
Wide range of shapes and sizes
The physical characteristics of the material make it possible to drill additional holes in the bathtub body for installing hydraulic massage nozzles, auxiliary handles or ultraviolet lamps. Since plumbing equipment is manufactured using casting technology, it is possible to use products of complex geometric shapes. Its outlines are limited only by technological tolerances (for example, the radii of surface joints must ensure that the matrix is filled with liquid material during the molding process).
The casting does not require additional mechanical processing of the internal surfaces - only the edges are ground and the feeders are removed. The thickness of the flanging of the product is uniform and does not decrease, as on stamped containers. It is possible to create marble baths with uneven wall thickness (subject to technological limitations).
An additional advantage of the products is the ability to machine the edges during installation (for example, when the equipment does not fit in the planned area).
Easy to install
The product is installed on a previously prepared floor surface on legs. Increased mechanical strength eliminates the need for additional fastenings to the walls and a metal frame. After installation, the front part of the bathtub is covered with a screen made of plasterboard or brick, in which technological holes are provided.
Ease of repair
Since the product is cast from uniformly mixed material of a given color, during operation there is no change in shades in individual areas.
Any mechanical damage that occurs (for example, scratches or chips) is removed by polishing or grinding, followed by restoration of the protective layer.
Ease of use
Metal baths have low heat capacity; the surface is perceived by the human hand and skin as too cold.
Structures made of cast marble feel warm; poured water slowly loses temperature. Thick walls reduce the noise level from liquid flowing to the bottom from the mixer gander; the resulting deposit of dirt and salts can be easily removed with household cleaning products.
Advantages of cast bowls
A high-quality marble bathtub has a number of advantages over cast iron and acrylic counterparts. For example, a significant range of models. On the plumbing market there are angular, oval, asymmetrical bowls. There is a choice of color and design. If desired, you can additionally equip the product with a hydromassage function - artificial stone tolerates vibration well.
On a note. A marble bathtub is easy to install. She stands steadily on her legs. There is no need to install a frame or attach the bowl to the wall.
A product made of cast marble is warm to the touch and maintains its temperature for a long time, so taking water procedures in such a bath is especially pleasant. Another nuance is high-quality sound insulation. This property is ensured by the high density and significant weight of the material. The noise of drawing water will not cause discomfort.
The service life of a bathtub is about 40-50 years. You can care for it with regular detergents. Minor chips and scratches do not affect the functionality of the product. The surface can be sanded and covered with a protective layer.
Important. The bowl is non-slip and therefore safe to use. The walls do not absorb dirt and are also not susceptible to the formation of mold and mildew.
Disadvantages of a marble bath
The disadvantages of equipment made of artificial material should also be taken into account:
- a complicated technological production process negatively affects the cost and final price of products;
- increased wall thickness increases the weight of the finished product, which makes it difficult to transport and carry to the installation site;
- to reduce the risk of damage to surfaces, it is recommended to use special cleaning agents;
- the surface of cast marble absorbs dyes (for example, coffee or tea leaves dark stains that are difficult to remove using standard methods);
- When exposed to heated objects, destruction of the surface is possible.
High price
To manufacture sanitary equipment from artificial stone, reusable molds are required into which a pre-prepared mass is poured. To improve the quality of the product, centrifugal compaction technology is used, which requires the use of special equipment. After removing the bath, the flash and feeders are trimmed, which further increases the manufacturing cost.
Difficult care
To remove dirt deposits, special substances are used that are gentle on the protective layer on the surface of the artificial stone.
If the varnish coating is damaged, the process of mechanical wear of the stone bath accelerates; the material absorbs dyes. It is recommended to wipe the surface of the product with a soft cloth after use, removing any remaining moisture and detergents.
Do not soak or wash items made from multicolored materials in a bathtub, as the pigment will settle on damaged areas (such as scratches or nicks).
Bulky plumbing
Equipment with a complex geometric configuration is supplied in wooden formwork, which makes transportation in an elevator car difficult. To deliver the bathtub to the apartment, a ladder is used, but during the carrying process the product may be damaged. Additional difficulties arise when installing a bath: it is difficult to move the product inside the room. For example, the Armada-170 bathtub from the Aquastone company has a volume of 260 liters, the weight of the product without packaging and additional elements is 100 kg.
Weak strength
The material can withstand increased load (3 times more than natural marble), but can collapse if heated unevenly. For example, when pouring hot water, mechanical stresses arise in the body of the bathtub, causing cracks to appear. When heavy metal objects fall, chips appear on the surface of the container, and part of the side may peel off.
Customer Reviews
Participants in various forums actively share with each other their experiences of using marble bathtubs. For example, Tatyana from Moscow liked the Estet Delta model. According to the woman, the surface does not absorb dyes, including homemade coffee scrub. The bowl was not damaged when a shower head accidentally fell into it.
Users Vitaly, Elena, Marina and others praise Astra Form products. Among the advantages are an impressive design and a feeling of comfort while taking a bath. A Muscovite with the nickname “Cranberries in Sugar” had a marble product that became chipped shortly after its purchase. But overall, the woman was satisfied with the purchase, since she admits that she is to blame for the appearance of defects (careless handling).
Attention! There are also frankly negative opinions about various models.
Reviews about marble baths are contradictory. To ensure that your desired purchase does not disappoint you, follow the basic tips for using and caring for the product. Often the cause of defects is not a manufacturing defect, but force majeure during delivery, installation, or careless operation of the bath by the consumer.
