This is popular with outdoor dining because it can seat a few people in small area where space is valuable. Potentially allowing for an additional unit to generate more revenue and maximize your space. To maximize dining space consider combination of 9.2ft and 11.5ft domes to accommodate groups of different sizes.
Additionally this unit is often paired and joined together with larger units in glamping functioning as the bathroom.
Picture shows how it can be connected easily and effectively (usually not ever double connected this is just showing the possibilities).
