Many American families are rethinking their bathroom habits, especially as bidets become more popular across the country. But is making the switch actually cheaper? When you dig into the numbers — installation, electricity, and those endless packs of toilet paper — the answer is clearer than you might think. Today, we’ll break it down using real Coway models and real U.S. prices.
How Much Does It Really Cost to Install and Run a Coway Bidet?
Coway is one of the top names when it comes to high-quality bidets. In the U.S., the Coway Bidetmega 150 typically sells for around $299, the Bidetmega 200 for about $399, and the more premium Bidetmega 400 for approximately $599. If you decide to hire a plumber, installation could add about $100 to your total cost, but many users opt for simple DIY setups without any extra fees.
Once installed, these bidets are incredibly efficient. They use around 50 kWh of electricity per year, which, at the national average of about $0.15 per kWh, adds up to roughly $7 to $8 a year in operating costs. That’s less than the price of one fancy coffee each year.
In short, setting up a Coway bidet will cost between $299 and $699 depending on the model, with almost negligible electricity costs of about $7 to $8 annually.
Toilet Paper Costs Add Up More Than You Think
It’s easy to overlook how much you’re spending on toilet paper because the purchases are small and frequent. But according to recent statistics, the average American household uses about 400 rolls per year. Even buying in bulk at Costco or Walmart, premium brands like Charmin Ultra Soft cost about $25 for a 30-roll pack. Doing the math, most families spend between $300 and $450 annually just on toilet paper.
And that’s under normal market conditions. Add in price hikes from inflation, shortages, or the switch to eco-friendly brands, and the costs can jump even higher without warning. Unlike a one-time purchase like a bidet, toilet paper keeps draining your wallet year after year.
Put simply, the average American household shells out about $300 to $450 every single year just on toilet paper — a cost that never really goes away.
Long-Term Savings: Coway Bidets vs Toilet Paper
Let’s run the numbers: buying and installing a Coway Bidetmega 150 costs about $399 including professional installation. Operating it costs roughly $7.5 per year. After one year, you’ve spent around $406.5. If you stick with toilet paper, you’re looking at $300 to $450 every year, with no end in sight.
By the second year, toilet paper expenses easily surpass the upfront bidet investment. After five years, a household could save between $1,200 and $1,500 just by switching. Plus, there’s no more late-night toilet paper runs, no worries during shortages, and a huge step forward for environmental sustainability.
In short, switching to a Coway bidet pays for itself in less than two years — and keeps saving you money every year after that.
