• Kaldewei manufactures its own enamel. This is the only way to guarantee optimum adaptation to the demands placed on bathtubs and shower trays

• Kaldewei bathtubs and shower trays cannot be scratched by the substances usually found in the abrasion bathroom
• if metal scratches on enamel, it is the metal which rubs off; the enamel is not affected

• steel is an excellent heat conductor and quickly assumes the temperature of its surroundings or of the water
• the heat absorbed by the steel fl ows back into the water when the water cools down
• Consumer tests have shown that even the sloping back rest above the surface of the water heats up
• the cooling behaviour of the water is the same for steel, cast and acrylic bathtubs since the heat of the water escapes almost exclusively from the surface of the water

• With Kaldewei steel enamel 3.5 mm with easy-clean finish, the water simply runs off the smooth, glass-hard surface taking practically all the particles of dirt and limescale with it
  
  

• The material strength of Kaldewei steel enamel 3.5 mm guarantees an unsurpassed stability
• Kaldewei steel enamel 3.5 mm is considerably harder than acrylic (see Mohs’ scale)
