We bought this to go over our hot tub.  Glad we went with the 16x12... the hot tub cover "just" clears when pivoting open.  The steps and railing in the photo were also bought on Wayfair! :)  It was mainly purchased to provide "screening" for bugs over the summer, but it will also protect the cover (from sun and hail) and allow us to use it in the rain too.  I had done a lot of searching various sites and types of hardtop gazebos.  We selected this one because of the snow rating and touted rust resistance.  The screens and privacy panels seem pretty durable (heavy duty) too.  It wasn't too hard to put together.  Did most of it myself over a few days.  Some steps needed some extra hands but most can be done by one person (just takes longer).  The real test will be how it holds up over time (especially winters).
