Exhaust fan in cathedral ceiling

I am doing some work and have the roof trusses exposed in my bathroom. The ceiling is cathedral and I need to add an exhaust fan. How do I do this with a cathedral ceiling? Do they make special fans/kits for that or is there a special way to frame it in?

If you have the depth, you can frame in and install one on the cathedral itself. The only problem I see is you will be stopping the free flow of air from your eave vents to the ridge vent in that particular section. Now, the best way is to frame down a box that is parallel to the floor and just slightly over the size of the grate of the fan you plan to install. This will allow enough space for free air flow, and enough space to install proper vent piping.
