Description Circa 1985 Gaylan Hightank Tank and Matching Seat. Here we have a Gaylan Toilet tank that was just in too good of shape to junk. So, we had one of our solid Red Oak seats finished to match to complete the set. The tank measures 19 3/4″ wide by 10 1/4″ deep and is 10 1/2″ tall. The tank does use particle board for the bottom and back, so this is aimed at a more budget-minded bathroom.
