If I set my water temperature to 50 deg celsius and have a shower why does the bathroom fill with steam, as this is half of the boiling point?

Boiling and evaporation are different processes. Evaporation can happen at any time from the **surface** of the liquid, while boiling is a bulk process where all the liquid may turn to gas. This is why you get the bubbeling when boiling, as gas bubbles are formed below the surface and rise. 

Evaporation increases with higher temperatures because the energy in the liquid is randomly distributed between the water molequles, giving some of them high enough energy to evaporate from the surface. The reason there is so much steam when you shower is that the evaporation only happens from the surface of the liquid. Small droplets have a large surface area compared to the volume, so naturally this allows for a lot of evaporation.
