We just finished a remodel in Lehi. Here is the handrail. The staircase in this home is a little cramped, but we did what we could to mitigate that without removing bearing walls or cutting a hole in the roof.
The simple, square, paint grade balusters are a favorite of mine. They give the handrail a clean look of strength. The newel posts are box newels. I built them myself to save money on the project. Building them saved about $900.
