Good Morning,
I have an older bathroom in a space with a thick concrete ceiling so a ceiling mounted bath fan is out. The bathroom is 12’6” x 9’6” with 8’ ceiling. Double vanity, shower, soak tub, & toilet. I am trying to properly vent this room. I think two 70cfm slim wall-mounted bath fans that vent down and through the crawl to the exterior wall will be sufficient. Can I connect both fans to the same switch to turn on simultaneously and can they be vented on the same main duct under the house? I was thinking I’d run 3” duct down into the crawl and then increase to 4” and combine them. I don’t want a direct vent bc the exterior wall is on the front of the house and would not look great. Any suggestions?
