I want to purchase a humidifier for my room will give enough humidity to make a steam-bathe out of it almost?

I recently purchased a Venta Sonic VS205 (ultrasonic), which puts a little thickness to the air (moisture) that is not seeable, but somewhat noticeable. I have never had a humidifier so I do not know if it does what it is suppose to do efficiently or not. But it does not do what I was hoping. I want to steam-bathe my room, or at least have the choice too. The Venta Sonic VS205 said humidifiers rooms up to 600 sq ft, which sounds big. I do not know the size of my room, but it's normal spare apartment bedroom size basically. I can't find any videos on youtube of humidifiers in action (at least purchasable). I don't have a whole lot to spend, but please let me know if you have suggestions. Perhaps I just need to get a humidifier that covers 3000 sq. ft?
