Help to buy new shower generator to me. I moved to new apartment and nowadays its into some rennovation. I want to order shower generator on amazon. 

I will be glad to share my experience. I just checked review on https://bathroomer.org/best-steam-shower-generator/ and choose new device without problem.  But friends, do not forget that steam showers have numerous benefits, including improving blood circulation; hence, a valuable thing to have in your bathroom.

Measure then Multiply. Measure then multiply the Length x Width x Height (in feet) of the steam enclosure to determine the Cubic Footage.

I too have been puzzled by such questions. I was also very concerned about mold or other problems when using a very hot shower near the door. So I decided to buy a hygrometer, and I couldn't decide on a model for a long time. In this regard, I was very helped by the website https://byrossi.com/the-best-hygrometers-for-home/ hygrometers for home and I also recommend you to read their articles.
