Portable Toilets for Mahjong Parlors

Mahjong parlors may use portable toilets to meet restroom needs, especially in open-air or space-limited venues.

Suitable Scenarios for Portable Toilets

In open-air mahjong parlors, the lack of fixed building facilities makes it difficult to set up traditional toilets, making portable toilets a flexible solution. For example, some open-air mahjong parlors have used plastic buckets placed in makeshift toilets for restroom use. Although relatively crude, this reflects the temporary need for portable toilets. Additionally, for indoor mahjong parlors with limited space or requiring rapid deployment, portable toilets can serve as supplementary facilities to alleviate restroom pressure during peak hours.

Composition and Types of Portable Toilets

Portable toilets typically consist of core components such as fecal wastewater storage tanks (or disposal units), flooring, and sanitary fixtures, featuring mobility, modularity, and ease of transportation. Depending on the disposal method, they can be classified into the following types:

• Flush Type: Supplied with water from a tank for flushing, requiring regular cleaning of the wastewater tank, suitable for scenarios with a water source and high hygiene requirements.
• Waterless Vacuum Type: Uses a vacuum pump to suction feces, requiring no water source but needing a dedicated suction truck for regular cleaning, suitable for water-scarce or environmentally stringent areas.
• Recirculating Flush Type: Recirculates water through biological degradation or chemical treatment to reduce water usage, suitable for long-term use and water-saving venues.
• Dry Pack Type: Uses biodegradable plastic bags to collect feces, requiring no water for flushing, with direct replacement of packaging during cleaning, simple operation but requiring regular replacement of consumables.

Alternative Solutions for Mahjong Parlors

Some mahjong parlors, aiming to enhance user experience, opt to set up private rooms with independent restrooms. For instance, Qingdao's 88 Teahouse · 24h Chess and Cards provides private and convenient restroom environments by equipping all private rooms with restrooms, avoiding potential hygiene or privacy issues associated with portable toilets. Although such designs incur higher costs, they significantly improve customer satisfaction and are suitable for mid-to-high-end or long-term operational venues.

Selection Recommendations

Whether a mahjong parlor adopts portable toilets should be comprehensively considered based on venue conditions, budget, and user needs. Open-air or temporary venues can prioritize portable toilets, focusing on matching disposal methods with environmental requirements; while fixed venues with sufficient budget may find setting up independent restrooms more conducive to long-term operations.
