Assumptions: Bidet reduces TP use by 75% (source, conservative vs. 75-90% reported elsewhere). Water cost adds ~$2/year (bidet uses ~0.125 gal/use vs. 37 gal to manufacture one TP roll). Tree savings estimated at 0.0004 trees per roll based on pulpwood conversion. Math is illustrative — your results will vary based on local water rates and TP usage habits.

Frequently asked questions

Will a bidet actually pay off for a single person?

For one adult using about one roll per week, a basic $40 attachment pays off in roughly 8-12 months. A $350 premium seat might take 3-4 years. Use the calculator above with your actual numbers — for single-person households, we generally recommend sticking with an attachment under $60.

Does the extra water use cancel out the savings?

No. A bidet uses around 0.125 gallons per use. At typical US water rates, that's about $2-3 per year even for a heavy-use household. Meanwhile, manufacturing a single roll of toilet paper takes roughly 37 gallons of water — the net water impact is strongly negative (meaning less water used overall).

What about electricity for heated seats?

Electric bidet seats with heating and warm water add roughly $1-3/month to your electric bill. We factored this into the premium seat assumptions. If your electricity rates are above $0.20/kWh, consider a non-electric attachment instead.

Why does the calculator assume only 75% reduction?

Most households still use some toilet paper for drying. 75% is the conservative middle of the 64-90% reduction range reported by manufacturers and independent reviewers. If you plan to air-dry or use a dedicated towel, you can mentally adjust savings upward by about 15%.
