In today’s episode, Build Show expert CJ dives into the increasingly popular world of flush exhaust fans. From standard drywall applications to intricate custom designs, he walks us through the benefits and installation details of the FITS exhaust fan system—formerly known as ARIA. Set in a beautifully finished, ultra-custom bathroom, CJ explains how this trim kit integrates seamlessly into the ceiling, offering a modern, aesthetically pleasing alternative to traditional bulky vent grilles. Unlike conventional exhaust fans that protrude and disrupt design flow, these flush systems maintain clean ceiling lines while meeting code requirements for ventilation in bathrooms and laundry rooms. CJ demonstrates both standard and custom applications, including a creative solution using tongue-and-groove ceilings where the vent is cleverly concealed without compromising airflow or style. Whether you're working on a new build or simply aiming for a sleeker design, this episode showcases practical tips, installation guidance, and why designers and architects are turning to these discreet ventilation options.
