Generally, the pros outnumber the cons of using a concrete bathtub. The arguments in favor include the versatility of the material, the possibility of a wide range of shapes and sizes of bathtub, as well as the durability and the smooth but easy-grip surface of the concrete.
Versatility is the main argument for the creation of a cement bathtub. Concrete is a very moldable material, so it can be made in almost any shape or size. A tub of this material can be build before any concrete installation allowing any design.
In addition to the infinitely adjustable size, it is also highly customizable the shape that can be given to the tub, which can be incorporated seats, declines or other structures in the design.
Another advantage offered by the construction of a concrete bathtub is the durability of the material. While it is not very likely that a tub is exposed to the weather, a good cement is very resistant to conditions in outdoor environments.
Concrete is also fire retardant, making it a good material to use when building appliances or furniture. Fire and weather, although rarely, can be highly destructive in a home, so it is a good idea to use durable materials inside the home to minimize the devastation when natural or unnatural disasters occur.
This material is also ideal for making tubs due to the smooth surface it creates when it dries properly. This is somewhat limited to the skill of the person who molds. The surface of the concrete bathtub is soft enough for the user to be comfortable when sitting inside, but it is also rough enough to allow the feet to grip the floor and avoid dangerous slips in the shower.
