I am renovating my house and adding a master bathroom to a master bedroom. We were recommended to buy a powerful vent system that would take care of 10 x 10 room with a full shower system and a bathtub. We ended up purchasing a panasonic, but our contractor was unable to connect it properly and he wanted to take it to the side of the house (which i did not want). Slavik from pro roofing suggested to take it out to the roof while we have the ceiling open. Very quick and easy, very nice guy. Will use them again.
