Customer Questions & Answers

Can this be installed on exterior of house?

Asked by: peggy
We do not recommend the Karina for exterior installations as the hardware is not marine grade stainless steel and will rust in the weather. Further, the treads have a very light polyurethane protective coating and that is not designed to withstand the weather elements for an exterior installation.

install staris without rails

Is it possible to install these stairs without installing the rails? I'm going for the "minimalistic" and "floating" stair look if possible.
Asked by: Al
Absolutely, you can install the Karina space-savings series of staircase kits without installing the handrail which is provided in the kit without compromising the functionality of the staircase.

Customer Reviews

Karina Grey Modular Staircase Kit is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Directions for assembly I purchased this unit for a unique corner of my home and after many hours of assembly it looks great however I will offer a few words of caution. First the instructional video shows one person lifting this unit to attach it to the wall and quite frankly I don't know how he does it because it weighs quite a bit and thats before you bolt on the stairs or the railings. Next I strongly recomend that you DO NOT pre drill the holes for the railing hardware to the steps as shown in the video. All of the instructions fail to tell you that depending on what configuration you twist the staircase in determines how the railings are placed. The printed instructions show two railing supports being fastened to each of the wide portions of every other step and that only works if you are installing this unit in a straight line only. If you twist the unit to fit your needs the railiings will attach quite differently. My recomendation is to erect the entire unit first and then map out the railings last before pre drilling holes in the steps otherwise you will find out that you may end up with a bunch of useless holes. If you do this just right you will have a beautiful and solid staircase. It is rugged and built to last forever.
