Toronto Gardenspin Spiral Staircase Kit

The Dolle Toronto Gardenspin Spiral Staircase kit is tough enough to hold up to the rigors of the outside elements due to its sturdy construction of hot galvanized steel, but chic and modern enough to make any interior room a great conversation design topic. The Toronto Gardenspin spiral staircase is recommended for high frequent use indoors or outdoors and can be easily installed in about a day using common household tools.

If you are looking for a staircase that looks great both outside and in, this is the spiral staircase for you!
