The toilet includes a bowl having flush holes disposed around a rim of the bowl for discharging water into the bowl, a water tank for containing a volume of water sufficient to cause the toilet to flush when the volume of water is discharged into the bowl, a flush and refill mechanism for flushing and then refilling the toilet, the flush mechanism controlling a flush valve that covers a drain at the bottom of the water tank. The adapter is fitted between the water tank and bowl with a first opening receiving the flush valve and a second opening connected to an exhaust fan by plumbing. The base plate may be translucent to allow LED lighting mounted to adapter to be cast about the bowl.
