In the beginning, it is of importance to mention that we produce bathtubs of cast sanitary acryl, which is the most qualitative material for the production of sanitary ware. Acrylic board has along its entire thickness an inner luster. Should the damage (deep scratches or stains from fire) be incurred on lustrous or matt surfaces, the same can be eliminated by fine “hydro” sandpaper, whereas a polishing paste can regain the initial luster. You can read more about this issue in the instruction for maintenance. Comparing with other bathtubs, the acrylic bathtubs do not lose their luster with the time. Acrylic bathtubs preserve the luster over the years of usage, since sanitary acryl does not allow settlement of bacteria, which create matt surface on the bathtub. Acrylic bathtubs are thermo stable and they have good insulating features. They keep the high water temperature for a long time and are comfortable for the human body. From the ecological point of view, these bathtubs are regarded as healthy. Owing to its molecular structure, the bathtubs from cast sanitary acryl are absolutely flat without any sliding surfaces. This characteristic can easily and practically be proven to the customer.
