bulthaup b3 offers a range of authentic materials that gives each kitchen its very own identity: These include stainless steel and aluminum, which contrast beautifully with the materials of their surroundings. Unique surfaces developed by bulthaup, such as gray aluminum and bronze aluminum, inspire with their changing effects. Stainless steel is used in the production of the monoblock and seamlessly connects the worktop to the side panels. Due to its hygienic properties, stainless steel is also used as a material for worktops.
