Island to Wall Clearance
How much room is needed behind island seating?
Fixed Obstruction Spacing
If there is a walkway behind seated guests, 44" to 48" is required. If there is no traffic behind the seats (e.g., against a wall), 32" to 36" is the minimum for someone to edge past.
A 36" minimum (42" preferred) gap between an island and a perimeter wall to allow for comfortable passage.
