The most common confusion within the stair building world is, without a doubt, the spiral versus the circular stair. It will not take long to clear this up.
The most common confusion within the stair building world is, without a doubt, the spiral versus the circular stair. It will not take long to clear this up.
A spiral stair has treads that are supported by a central support post. They usually have a very tight diameter of 48 to 72 inches, and are not recommended as main stairs in any inhabited structure.
A circular stair has two stringers supporting treads and (typically) risers, and will take up a much larger floor space than a spiral.
