Stainless steel provides many advantages, especially in a kitchen setting where sanitation and durability are a priority.
One main advantage is the non-porous quality of stainless steel. The fewer pours a material has means that there are fewer places for bacteria and grime to hide and grow. It also means it will not absorb stains, leaving you with a cleaner, brighter surface.
Another advantage is its durability and scratch-resistance, which is important when chopping, slicing and dicing are a common occurrence. It is also helpful with moving and using countertop appliances like mixers and blenders.
One of the best reasons to have a stainless steel kitchen is its affordability. It is usually quite reasonably priced considering the advantages it brings with its use.
