checkout stairsupplies.com, we ordered from them and my contractor found it easy to install. Lots of options for railing, newel posts, and steel/iron balusters.

I like what you currently have. Perhaps adding colorful rugs would give you an updated look? Maybe a fancier light and artwork would be nice, too. These might not be what you are looking for, but sometimes updates are really not improvements.

Grapefruit1_ar , I just find the look is so dated- not vintage or classic just dated- I considered painting - I think rugs could be a tripping hazard for my girl. Your right I need a new light and art

BeverlyFLADeziner I never considered white spindles but that is a nice soft look with the wood- might suit my bamboo- thanks

There are some DIYs out there using your existing post. Just google on Pinterest and a lot will pop up. You could update it and paint the spindles and railing, unless you just want a totally different look. I think part of the issue may be the color of the walls while it's nice, it's a dated look for the current trends, so you may want to consider painting walls along with the railing if time and money allow.

Thanks Emily- I am going to be painting the walls in an off white, probably using Calm- so with that perhaps just covering the Newell post and painting the spindles white- only thing is my gate has black metal- I’m adding a pic

You could have a gate made so the spindles and height were the same, but if that's not an option I think I'd just paint them all the same.
