$4.3M/Year From His Low-Tech, AI-Proof Business

  • Daniel Tom

  • Portable Toilet Rental Operator
  • $4.3 million per year

Daniel Tom was studying to become a PE teacher.

Then he took a part-time job at a porta-potty company – and never looked back 💪

After 7 years working for another company, Daniel launched Bay Area Sanitation in 2023 with one truck and 100 toilets…

When I tell people that I own a porta-potty business, I get a lot of disgusted looks.

But once I explain to them the business model and the revenue, most of the time they get interested.

Three years later he’s running 12 trucks and almost 2,000 portable toilets across 500+ job sites in the Bay Area.

Total income in 2025: $4.3 million 🤑

The bulk comes from long-term construction rentals – each toilet brings in $60/week, and projects can run for years.

I like to focus on long-term rentals because it equals guaranteed recurring revenue for my business.

Net profit margin: 22% 👇

We’ve managed to build what I think is a low-tech, AI-proof business.

Every toilet on rent adds another $160+/month in recurring revenue. And the beauty of a business nobody wants to touch – literally – is that there’s always room for another operator 😎
