Restaurant Smart Public Toilet System: Restroom Availability Display and Directional Guidance

Providing clear restroom information is an important part of the visitor experience in restaurants, shopping centers and other commercial facilities.
In large dining areas, visitors may need to walk some distance to reach a restroom. Traditional directional signs can indicate where the restroom is located, but they do not necessarily provide information about the number of available stalls.
A digital restroom availability display offers another way to present this information.
This restaurant application case demonstrates how a Smart public toilet system display can combine male and female restroom availability, directional arrows, distance information and multilingual messages on one screen.

1. Restroom Availability Display for Male and Female Toilets

The display interface separates male and female restroom information into two sections.
In the provided photos, the displayed information includes:
  • Women’s restroom: 3 available stalls.
  • Men’s restroom: 2 available stalls.
The remaining stall numbers are presented alongside recognizable restroom symbols.
This visual layout allows visitors to identify the displayed availability information without reading lengthy instructions.

2. Directional Guidance for Restroom Navigation

In addition to availability information, the screen provides directional guidance.
One display shows a right-pointing arrow with a distance indication of 152 meters. Another image shows a left-pointing arrow.
Combining restroom availability with directional information helps visitors understand both the displayed stall status and the direction in which they should proceed.
This type of display can be considered for restaurants, shopping malls and other commercial facilities where restrooms are located away from the main visitor area.

3. Multilingual Information Display

The interface contains Vietnamese, English and Chinese text.
Multilingual information is useful in international dining environments and commercial facilities that serve visitors from different language backgrounds.
The display also includes a message advising visitors to use the public restroom on the same floor when no restaurant stalls are available.
This provides an alternative direction instead of simply showing that the restroom is full.

4. Alternative Restroom Guidance When No Stalls Are Available

The bottom section of the display contains an explanatory message.
When the remaining restaurant restroom capacity reaches zero, visitors are advised to use the public restroom in the shopping mall on the same floor.
This information helps users understand what to do next and can reduce unnecessary searching for another available restroom.

5. Typical Application Scenarios

Similar restroom information displays can be considered for:
  • Restaurants and large dining facilities.
  • Shopping malls and commercial complexes.
  • Airports and transportation facilities.
  • Tourist attractions and visitor centers.
  • Large public buildings.
The actual system configuration depends on the number of restrooms, site layout, availability data source, communication requirements and display locations.

6. SUNPN Technology Smart Public Toilet System Solutions

SUNPN Technology provides solutions covering Smart public toilet systems, synchronized clock systems, passenger flow counting systems, AI vision counting systems, environmental monitoring displays and urban electronic information displays.
For restroom projects, the display layout and information content can be planned according to site conditions and operational requirements.
This restaurant case illustrates how digital displays can bring restroom availability information, directional guidance and multilingual instructions together in a unified visual interface.


A restroom availability display is more than a directional sign. It provides visitors with useful information about available stalls and restroom locations before they reach the destination.
For restaurants and commercial facilities, a well-planned Smart public toilet system can support clearer wayfinding and a more organized public restroom information service.
