Two thousand toilets
Daniel Tom is 31 and runs Bay Area Sanitation, a fleet of almost 2,000 portable toilets serving construction sites and events around San Francisco. The company reported $4.3 million in total income in 2025. His day starts at 4 a.m.
Every business in this database is unglamorous. Daniel Tom's is the reigning champion. Bay Area Sanitation delivers, services, and pumps out portable toilets across the San Francisco Bay Area, a fleet of nearly 2,000 units on construction sites and at events, run by Tom and 19 employees. CNBC Make It reported the company's 2025 total income at $4.3 million.
Tom's framing of the moat is the best one-liner in modern boring-business coverage: he calls it a low-tech, AI-proof business. No model, agent, or app removes what his vacuum trucks remove. Demand is not a trend either; construction sites above a certain crew size are legally required to provide sanitation, which makes every active building permit in a metro area a mandatory customer for somebody.
The capital equation
The startup math he shared is refreshingly concrete: about $800 per rentable toilet and roughly $160,000 per vacuum truck, with perhaps $250,000 needed for a credible start. Labor is the biggest line, around 30 percent of revenue for his 19-person team, followed by fuel and consumables like paper. The units themselves are nearly indestructible assets that rent month after month, year after year.

What Tom pays himself is the most instructive number: roughly $120,000 in salary, deliberately modest against a $4.3 million operation, because the rest is reinvested in units and trucks. His stated five-year target is 5,000 toilets and $10 million in revenue. The mornings are 4 a.m. starts at the yard, dispatching crews to deliver fresh units and service long-term rentals; office days are sales calls and growth planning.
The tolerance premium
Tom is candid that the work filters out nearly everyone, and that after enough years the smell mostly stops registering, with exceptions he describes vividly. That disgust is not a bug in the business model. It is the barrier to entry, and it prices in a premium that cleaner industries have competed away. The Boring Index scores it 99, the highest mark we have awarded.
Common questions
How much does a porta-potty business make?
Bay Area Sanitation reported $4.3 million in total income in 2025 from almost 2,000 units. Tom takes about $120,000 in salary and reinvests the remainder in fleet growth. Smaller routes earn proportionally: the asset count is the business.
What does it cost to start a portable toilet company?
Tom's estimate is about $250,000 for a credible start: units run around $800 each, and the vacuum truck, the real gatekeeper purchase, around $160,000. Labor then becomes the largest ongoing cost, about 30 percent of revenue in his operation.
Why is demand for portable toilets so stable?
Because much of it is legally mandated: construction sites above modest crew sizes must provide worker sanitation, so every active building permit in a metro is recurring demand for someone. Events stack a seasonal layer on top.
