Broan/NuTone now offers bath fan upgrade kits. The Broan 690 and NuTone 690NT Bath Fan Upgrade Kits include a fan grille, a quieter, more powerful fan motor, a wrench, two motor plates (depending on the existing fan model) and step-by-step instructions. The company says the kits can help transform a bath fan from loud, ineffective and unattractive to quiet, powerful and modern in 10 minutes.
