You only need an extraction fan or some sort of ventilation within the bathroom its self. Our showers do not provide extraction fans as simply they are not required.

I’ve seen other companies have them installed on their showers?

This you may have seen; however, they are simply not required. Think about it, when you are steaming you want to retain the steam within the cabin not ventilate it out and when you have finished you simply open the cabin doors and the steam pours out into the bathroom anyway! What will the small fan inside the shower do? Secondly, when you are showering, any steam created within the cabin simply condensates on the shower roof, turns into water, and filters down the cabin walls. It’s for these reasons and our continual design and development that we don’t install them. It has nothing to do with cost.
