Quoted from meSz:I have not, sorry! You could do some harnesses but they would need to be shorter ones. If it helps the "tub" is approximately 9.75" x 5.75" x 2.75". The 2.75" is the depth.
One of the drawbacks to this model is there is no ON/OFF switch. You have to unplug it every time.
You could install a switch on the cord easily with one from Home Depot or Lowes. Or simply plug into a powerstrip with an on and off switch.
