During the construction of a log bath, the main material is round logs or a calibrated timber. The logs are laid in rows, making on the bottom of each log of the grooves that create the stiffness of the design of the bathhouse. Cut through the grooves, the log is laid on the rounded surface of the previous log. At the time of laying the logs between them, a pacley layer is placed either a hemp point, or a moss with a width of more than one centimeter.
