Washrooms are a ubiquitous, yet essential element connected with day-to-day living environments. Public washrooms or restrooms are a common feature in all public buildings. They are often linked to the notion of 'unclean' environments, due to the sheer number of people who use its services. From a health and safety perspective, it is imperative to maintain hygiene standards that will provide confidence to its users. This is especially true in the Covid-19 pandemic situation, where disinfection is of prime importance. Several elements contribute to a clean washroom, and some elements can benefit from Internet of Things (IoT) technologies. This paper introduces a framework for the use of IoT technology for implementing a Smart Washroom. Our research further explores public perception of clean washrooms and introduces a novel mobile app-based approach to locate clean public washrooms.
