These storm shelters are both 6×8 on the inside, but the easy access storm shelter is 8″ taller, making it 6’10” inside instead of 6’2″. Both storm shelters have 6 steps, but the steps in the easy access storm shelter are wider and more of a “staircase” style. The stairs do take up more room on the easy access storm shelter, but there is plenty of space behind them to store emergency supplies and important documents.
