Adding bathroom ventilation was a must do in our space, however i have a big bathroom & the shower head is massive in there! The heat from the shower creates a lot of steam. I hated that our mirror was always fogged over. I would get condensation all along the walls that I would have to mop up. I was constantly fighting mold in the shower & the corners of the bathroom. I immediately went online & looked up ventilation helpers. I found that you can spend anywhere from 10 to multiple hundreds of dollars on bathroom ventilation. I sprung for a wonderful system. I have a bathroom ventilation method with an LED light that turns on when you walk in the shower. It automatically removes the heated air from the indoor air quality to cool the space down. It is said to lower the Heating, Ventilation, & A/C bills if you have wonderful bathroom ventilation. I assumed that a Heating, Ventilation, & A/C professional would do the upgrade. I mean it stands for heating, ventilation & air conditioner, well after I had the Heating, Ventilation, & A/C guy in there he told me he installs ventilators, HVAC duct & indoor air quality equipment; Bathroom ventilation was certainly an electrical task that our local electrician did. It was unusual calling a unusual professional in. I felt a Heating, Ventilation, & A/C worker should drill holes into the side of our apartment to pump air outside, but however the electrician did a wonderful task, however my space is cooler, less muggy & I do savor how it feels after a shower. I don’t clean up half as much mold anymore.
