Electric versus propane toilets: Which has lower long-term costs?

Electric Toilets: Lower Fuel Costs

Electric toilets typically cost between $0.02 to $0.04 per kWh to operate, depending on the local electricity rate. Assuming an average usage of 500 gallons per month, an electric toilet that uses 1.6 gallons per flush would cost approximately $6.40 to $12.80 per month. In contrast, a propane toilet that uses 1.6 gallons per flush would cost around $15 to $30 per month, depending on the propane price and usage.

Propane Toilets: Higher Maintenance Costs

Propane toilets require regular maintenance to ensure proper function and safety. This includes inspecting and replacing worn-out seals, cleaning the burners, and checking the propane tank. Additionally, propane toilets need to be vented properly to prevent carbon monoxide buildup, which can be a significant installation cost. In contrast, electric toilets have fewer moving parts and require less maintenance, reducing the overall cost of ownership.
