CTAS – The Versatile Restroom Access Control Solution

Restrooms, particularly those in commercial businesses and public areas, are designed to be multifunctional and inclusive spaces that provide a range of shared benefits to people in the community. Restrooms are supposed to be a safe and serviceable public amenity. However, most public restrooms are reported to encounter security problems. Since it is easily accessible and free from surveillance, restrooms can also be a recurring place for illicit activities and crimes such as vandalism, drug selling, robbery and sexual assault. 

Having a restroom access control solution is crucial to guarantee security, privacy and customer convenience. In order to avoid felonious acts inside, restrooms should install lockable exterior doors to control access and eliminate security risks. Built-in controls or codes are given to customers or authorized staff members to obtain access to the restroom. This new solution makes public restrooms usable and safe for many people.

  • Corporate companies
  • Government organizations
  • Hospitals
  • Malls and retail shops
  • Restaurants and food service establishments
  • Schools
  • Gas stations

What Are the Options for Controlling Restroom Access?

There are several options for controlling restroom access. These include:

  • Keyed Locks
    • Key-controlled locks are the most typical solution for restroom doors, wherein customers are handed out with loan keys temporarily for restroom access. This option is low-priced and accessible to customers. The downside of this option is the grueling routine for employees who are assigned in handing out and retrieving the keys to customers and also the tendency for lost or stolen keys, requiring lock replacement and rekeying.
  • Keypad Locks
    • A keypad lock is another common option for restroom doors. It includes a keypad code that will be given out to customers (usually printed on the receipt) who request to use the restrooms. It is more convenient and hassle-free than keyed locks. The only disadvantage of this option is that keypad codes can be shared from person-to-person so regular password change is required.
  • Token-Operated Locks
    • A token-operated lock is derived from the traditional “pay token” method, in which a custom token-operated lock is equipped on every restroom door. It requires a metallic token in lieu of keys and codes, provided exclusively to a single customer who requests for restroom access.
  • Remotely-Operated Locks
    • Remotely-operated locks involve installation of electric lock equipment on all restroom doors and a remote door release button is built on every customer service section. To request for access, the employee must press the button to unlock the door for a specific time of 60 to 120 seconds. 
  • Touchless Locks
    • Touchless solutions like the use of video surveillance systems and automatic door operators can also be effective for restroom access. This option requires a particular software with push buttons or installation of surveillance cameras in corridors or adjoining areas of the restroom. The access door will only be unlocked when the customer is standing near the restroom area.
