Sinkside Billboards
Turns bathroom sinks and washroom spaces into digital out-of-home advertising surfaces — a high-attention media channel in locations where brands reach captive audiences. Venues gain new revenue streams while smart water-saving faucet technology is incorporated. 1-in-12 ads dedicated to purpose-driven charitable causes.
Sinkside Billboards has identified one of the most overlooked high-dwell-time environments in advertising: the washroom sink. Users typically spend 20-60 seconds at a sink — long enough to absorb a meaningful advertising message, in a location where digital screens and smartphone distraction are absent. Sinkside installs digital display surfaces at sink-level in venues ranging from restaurants and hospitality to stadiums and corporate campuses.
The business model provides venues with a new revenue stream (advertising revenue share), brands with a novel and highly viewable premium placement, and the platform with scalable recurring media inventory. The integration of smart water-saving faucet technology adds an operational value layer that facilitates venue adoption. The 1-in-12 ad charity commitment is deeply embedded in the company's identity — not an afterthought — and resonates with both venue partners and consumers.
The U.S. out-of-home advertising market exceeds $8 billion annually, and digital OOH is the fastest-growing segment. Premium, high-dwell-time placements command significant CPMs. Captive audience media — elevator screens, in-flight entertainment, restroom advertising — consistently outperforms typical outdoor formats on attention metrics. The global restroom advertising market is nascent, representing a significant first-mover opportunity.
