【The characteristics of our stone-slab bath】

●One of the main characteristics of our stone-slab bath is its low running cost (labor costs, light and fuel expenses)!! The setting temperature is the extent of 37-40 degrees Celsius (℃).And the setting degree of humidity is in the vicinity of 60%. You can get the best performance out of this condition (you can sweat freely).  Black silica bring out the highest emission rates of far infrared rays when the temperature hit 39.9 degrees Celsius, so you need to set up neither high temperature nor extremely high degree of humidity.

When the degree of humidity reaches 90%, dew condensation water happens to fall from the ceiling. In that case you need to wipe them off frequently. That is to say, the labor cost is needed. Also, you can cut down the energy (electricity, kerosene, gas), because you don't need to set up high temperature more than necessary.

●As mentioned above, black silica brings out maximal performance at a temperature of 39.9 degrees. The temperature of the stone-slab bathroom is normally adjusted by under floor heating which warms up black stone-slabs. If the temperature of the bathroom becomes high, you are easy to sweat. For that purpose you warm up the black silica more than necessary and that is wasting of energy. Be aware that the bathroom might become sweaty due to ' excess sweat'. Therefore our model room is controlled to adjust room temperature at 37 to 40 degrees.

●The amount of the black silica stone used for our stone-slab differs from others. We use plenty of black silica not only for stone-slab but also for the parts under the slab. So the price per slab is a little expensive, but the far infrared rays and the deodorizing effects are remarkably high.
