Frequently Asked Questions
Will a bidet really save me money compared to toilet paper?
Yes, absolutely. Even a budget attachment ($30-40) pays for itself within 2-3 months. Over 5 years, most households save $300-500 after accounting for the initial cost.
How much water does a bidet use versus flushing toilet paper?
A typical bidet uses 1-2 gallons per use, while flushing the toilet multiple times for wiping uses 5-6 gallons per session. Bidets actually reduce total water usage.
Is a bidet cleaner than toilet paper?
Yes. Studies show bidets remove 99% of bacteria, while toilet paper leaves 0.1-1% residual. Bidets are objectively more hygienic.
Do bidets damage plumbing or septic systems?
No. In fact, bidets reduce strain on plumbing by eliminating excessive toilet paper. They're safe for all plumbing systems and recommended for those with septic tanks.
