Toilet paper is about to cost more. On August 26 the Guardian reported that the US and Canada have entered a full trade war, and paper products are on the front line: Washington has put a 50 percent tariff on Canadian toilet paper and tissue stock, and Canada answers on September 8 with 25 to 50 percent tariffs of its own. If you read that headline and thought about a bidet, this guide does the math, including the part nobody publishes for a $1,290 smart toilet.
Quick Answer: Yes, a Bidet Saves Money, and How Much Depends on How You Dry
A bidet cuts a household's toilet paper spending by 50 to 70 percent if you still pat dry with paper, and by 90 percent or more if you dry with a warm-air dryer or a towel. A family of four spends roughly $160 to $240 a year on toilet paper at late-August 2026 prices, so that is $100 to $170 a year saved in the typical case and $150 to $220 in the best case. Either number is larger than any realistic tariff increase on your toilet paper bill, so a bidet does more than offset the price rise. It erases most of the line item.
The honest caveat is the up-front cost. A $40 attachment pays for itself in four to six months. A $300 to $500 electric bidet seat takes three to six years. A $1,290 integrated smart toilet like our ST-01 does not pay for itself on paper savings alone in any horizon you would plan around unless you were replacing a toilet anyway and you use the dryer. If that is you, paper savings cover the premium over a standard toilet in about five to twelve years. The rest of what you pay is for warm water, a heated seat, an automatic lid, and a dryer, and you should buy it for those reasons or not at all.
This is Badeloft's answer to the money question. We make an integrated smart toilet, so we have a stake in the answer, and the way we handle that is by showing every input and letting you change them. When we say bidet, we mean all three tiers: the $40 cold-water attachment, the electric seat that bolts onto your existing toilet, and the integrated smart toilet with the bidet built in. If you buy Costco 30-packs for a house with kids and the headline gave you a 2020 flashback, the savings section is for you. If you are mid-remodel and choosing between a standard toilet plus a seat or an integrated unit, the payback section is the one to read twice. And if you rent a one-bedroom and just want the paper bill to stop, we will tell you, plainly, to buy the attachment.
By the end you will know what your household actually spends, how much of it a bidet removes, what a smart toilet costs to run at 2026 electricity rates, and the year your purchase breaks even. We have grouped it into four parts: what the tariff does to your bill, what a bidet saves, what it costs to buy and run, and who should buy which. Start with the headline itself, because most of what is being said about it is not quite right.
What the Canada Tariff Does to Your Toilet Paper Bill (and What It Does Not)
The tariff raises the cost of the raw material inside American toilet paper, not the finished product on most shelves. Charmin, Cottonelle, and Kirkland are largely made in US mills, but those mills lean on Canadian softwood pulp, and the US imported $328 million of finished toilet paper from Canada in 2024 on top of that, according to the World Bank data cited in the Guardian's August 26 report on the paper tariffs. Procter & Gamble, which owns Charmin, had already announced tariff-related price increases before this round. Canada's September 8 retaliation hits US paper exports going north, so it is Canadian shoppers who feel that one directly.
Nobody has published a shelf-price forecast yet, and anyone quoting one is guessing. The US trade representative says consumers will not be affected at all. The last time a lumber tariff scare hit the news, in April 2026, searches for "toilet paper shortage" jumped from nothing to more than a thousand a month and people started stockpiling again. Panic-buying is the expensive reaction: you pay today's price for paper you will not use for a year, and you store it in a garage. So instead of a forecast, here is a sensitivity table you can read against whatever the price turns out to be.
| Tariff pass-through to shelf price | Family of four, annual toilet paper spend | Extra cost per year | What a bidet at 60% reduction saves |
|---|---|---|---|
| 0% (today, late August 2026) | $200 | $0 | $120 |
| +10% | $220 | $20 | $132 |
| +20% | $240 | $40 | $144 |
| +30% | $260 | $60 | $156 |
| +50% (the full tariff, passed straight through) | $300 | $100 | $180 |
Read the last column. Even a bidet used with paper for drying saves more than the worst-case tariff adds. The tariff is why people are asking this week; the savings were there in 2019 at 2019 prices.
How Much Toilet Paper a Household Actually Uses (and Why 141 Rolls and 50 Rolls Are Both Right)
The average American uses 141 rolls of toilet paper a year, about 12.7 kilograms, the highest figure in the world according to Statista's Consumer Market Outlook. You will also see people on Reddit say the number is "about 50 rolls, one a week." Both are correct. Statista counts standard rolls. The rolls you buy at Costco or Target are double or mega rolls, each worth two to four standard rolls, and 12.7 kilograms of paper works out to roughly 50 of those big rolls. If you go through about one big roll per person per week, you are exactly average.
What does that cost in 2026?
A big roll costs $0.80 to $1.10 at warehouse-club prices. In late August 2026, Costco lists Kirkland Signature at about $0.83 per roll and Charmin Ultra Strong at about $1.13 per roll. Premium brands at a grocery store run higher, and Quilted Northern was selling at more than $1.50 a roll in late 2025. Fifty big rolls at those prices is $40 to $55 per person per year, which lines up with Statista's top-down estimate of about $45 per person across the whole US market.
| Household | Big rolls per year | Annual spend at $0.80 to $1.10 per roll | With kids or premium brands |
|---|---|---|---|
| 1 person | ~50 | $40 to $55 | up to $75 |
| 2 people | ~100 | $80 to $110 | up to $150 |
| 4 people | ~200 | $160 to $220 | up to $300 |
| 5 people | ~250 | $200 to $275 | up to $375 |
Be suspicious of any bidet seller telling you a person spends $120 to $180 a year on toilet paper. That figure is unsourced and roughly three times what the market data supports. The savings are real without inflating the starting number, and we would rather you trust the rest of this page.
How Much Toilet Paper Does a Bidet Actually Save? Three Real-World Tiers
A bidet saves between almost nothing and almost everything, and the deciding factor is what you do after the wash. The 75 to 80 percent figure most sellers quote is a blended average that hides three very different households. We pulled 120-plus firsthand reports from the r/bidets thread "How much toilet paper are you now saving" and they sort cleanly into these tiers.
If you wash, then pat dry with paper: 50 to 70 percent
Most households land here. You use two or three squares to dry and, as one of the top-voted comments put it, "to check to make sure the bidet got everything." Paper use drops by half to two-thirds. For a family of four at $200 a year, that is $100 to $140 saved. Kids and guests keep you at the low end of the range, because as another parent wrote, "the kids say no way you do away with toilet paper."
If you dry with a warm-air dryer or a towel: 90 percent or more
Households that dry with a towel or a built-in dryer report the numbers that sound made up: "went from a Costco 30-pack a month to one a year," "about 95 percent savings," "still using the same two rolls from COVID." A dedicated small towel per person, washed with the regular laundry, is the cheapest route here. A warm-air dryer is the built-in route, and dryers on cheaper seats are often weak and slow (one r/bidets owner called a well-known seat's dryer "weak and ineffectual"). The ST-01 has a warm-air dryer built into the bowl. Budget 30 to 60 seconds of dry time with any of them.
If you wipe first, then wash: close to zero
Some people use the bidet as a rinse after a full paper wipe. You will be cleaner and your paper bill will look the same. If this is how you expect to use it, buy the attachment for the cleanliness and leave the savings out of the decision. The savings appear when the water does the cleaning and the paper, if any, does the drying.
Picture a family of four in a three-bathroom house, two adults and two school-age kids, buying a Costco 30-pack about every seven weeks. They put a bidet on the primary bath only. The adults pat dry with paper, the kids ignore the thing entirely. Their next 30-pack lasts eleven weeks. That is a 35 to 40 percent household reduction, about $70 a year, from one bathroom and half the people. Add a second unit in the kids' bathroom and the number roughly doubles. The tiers above describe a household where everyone uses it; partial adoption scales the number down in proportion.
Do You Still Need Toilet Paper With a Bidet?
Yes, most people keep some, and it is smart to plan on it. You will want paper for drying if you do not have a dryer or towel, for guests who will not use the bidet, for checking, and for the days your household is sick. Plan on buying one big pack a year instead of one every month or two, and keep a roll in every bathroom.
The water side of this question is easy. A bidet wash uses about an eighth of a gallon. Scientific American estimated back in 2009 that making one roll of toilet paper takes about 37 gallons of water, 1.3 kilowatt-hours of electricity, and 1.5 pounds of wood. The numbers are old, but the ratio is not close. Drying with a few squares after a wash does not put you back where you started.
What a Bidet Costs Up Front: Attachment vs Seat vs Integrated Smart Toilet
You have three ways to get a bidet and they cost $40, $400, and $1,290 in round numbers. Which one is right depends on whether you need warm water, whether you have an outlet near the toilet, and whether you are replacing the toilet anyway.
| Tier | Typical price | Needs power? | Warm water | Dryer | Best for |
|---|---|---|---|---|---|
| Cold-water attachment | $35 to $70 | No | No | No | Renters, single people, "just make the paper bill stop" |
| Electric bidet seat | $250 to $600 | Yes, outlet within reach | Yes | Usually, often weak | Homeowners keeping a toilet that is in good shape |
| Integrated smart toilet (ST-01) | $1,290 | Yes, 110 V within 35 inches | Yes, tankless and instant | Yes | Anyone replacing a toilet, remodels, aging in place |
If your toilet is fine and you have an outlet, the electric seat is the value pick, and we say that as a company that does not sell one. If you are replacing the toilet, the comparison changes: the ST-01 is competing against a $400 to $600 standard toilet plus a $300 to $500 seat, not against zero. Elongated seats have to match an elongated bowl, seats add height and a visible power cord, and a two-piece assembly has more seams to clean. An integrated unit is one ceramic bowl with the electronics inside it.
Whichever tier you pick, the outlet is the hidden cost. A cold attachment needs none. Anything heated needs a GFCI outlet within about three feet of the toilet, and if the bathroom does not have one, an electrician will charge $150 to $350 to add it, more if the wall is tile. One Houzz remodeler described having an outlet installed "just in case" during a remodel and being glad of it two years later. If you are opening walls anyway, run the outlet now. It is the cheapest moment you will ever have.
What a Smart Bidet Toilet Costs to Run in 2026 (Water and Electricity)
A heated smart toilet costs roughly $35 to $65 a year to run for a family of four at the US average residential electricity rate of 18.3 cents per kilowatt-hour (US Energy Information Administration, June 2026). Water adds $2 to $4. Call it $45 a year in a typical home, and subtract it from the paper savings before you calculate payback. That range is built from component wattages, not from a meter on an ST-01, so treat it as an estimate rather than a specification.
Does a heated seat run up your electric bill?
No. A heated seat draws 30 to 60 watts while heating, which our heated toilet seat guide works out to roughly $1 to $2 a month. Left on at full heat around the clock with no eco mode, the worst case is about 350 kilowatt-hours a year, or $64. A seat that drops to standby when nobody is in the room uses a third of that. A claim went around r/bidets that a heated washlet would raise a household's electricity use by 35 percent. For a home using 200 kilowatt-hours a month, that would be 840 kilowatt-hours a year, two to three times the worst published measurement of any bidet seat. It does not hold up.
The water heater is the other draw. Tank-style seats keep a small reservoir warm all day. The ST-01 heats water on demand through a tankless element, so the heater runs only during the wash: on the order of 1,200 watts for about a minute, eight times a day for four people, which is about 60 kilowatt-hours a year, or $11. The dryer is similar, about $10. The deodorizer, night light, and sensors are a few dollars combined.
Do bidets run up your water bill?
No. Four people washing twice a day at an eighth of a gallon per wash use about 365 gallons a year, which is $2 to $4 at typical municipal rates of $4 to $10 per thousand gallons. A single extra flush a day costs more than that.
The Honest Payback Math for a $1,290 Smart Toilet
At full price, the ST-01 pays for itself on toilet paper in roughly 9 to 17 years for a family of four, depending on how they dry. That is longer than most people stay in a house, and we are not going to pretend otherwise. Paper savings alone do not justify an integrated smart toilet. Two things change the number: whether you were buying a toilet anyway, and whether you use the dryer.
| Purchase | Net cost | Net annual savings, paper-dry (60%) | Payback | Net annual savings, dryer or towel (90%) | Payback |
|---|---|---|---|---|---|
| Cold attachment | $40 to $60 | $120 | 4 to 6 months | $180 | 3 to 4 months |
| Electric seat | $300 to $500 | $85 | 3.5 to 6 years | $145 | 2 to 3.5 years |
| ST-01, full price | $1,290 | $75 | ~17 years | $135 | ~9.5 years |
| ST-01, premium over a standard toilet you were buying anyway | $690 to $890 | $75 | 9 to 12 years | $135 | 5 to 6.5 years |
| ST-01, premium over a standard toilet plus an electric seat | $190 to $590 | $0 (same paper savings either way) | Not a paper decision | $0 | Not a paper decision |
Assumptions: family of four spending $200 a year on toilet paper at late-August 2026 prices; electric tiers net of $35 (seat) or $45 (ST-01) a year in operating cost; a standard elongated toilet at $400 to $600 installed. Change any input in the calculator below and the table recalculates.
Bidet savings calculator
Change any input. Prices default to late-August 2026 warehouse-club numbers. Payback is net of estimated operating cost.
| Option | Cost to you | Yearly operating cost | Net saving per year | Pays for itself in |
|---|
Assumptions: attachment $50, no operating cost. Electric seat $400, about $35 a year in electricity and water. Badeloft ST-01 $1,290, about $45 a year (estimate, pending measured draw). Operating costs use the June 2026 US average of 18.3 cents per kilowatt-hour. Outlet installation, if needed, is extra for the electric options.
If you are replacing a toilet anyway
Then the right comparison is the premium, not the sticker. You were going to spend $400 to $600 on a decent elongated toilet and someone to set it. The ST-01 costs $690 to $890 more than that, and it pays that difference back in 5 to 12 years on paper savings, faster if you use the dryer and faster still if paper prices rise. Say you are gutting a primary bath this fall. The plumber is already there, the wall is open, the outlet costs $40 in wire instead of $300 in patching. The premium is the smallest it will ever be and the toilet will outlast the tile.
If your current toilet is from before 1994
Add water savings to the math, and only then. Toilets made before the 1994 federal standard use 3.5 to 6 gallons per flush against 1.28 for a toilet built to WaterSense criteria like the ST-01, and the EPA's WaterSense program estimates replacing an old toilet saves the average family nearly 13,000 gallons and more than $170 a year in water costs. That single line can bring the ST-01's full-price payback under seven years. If your toilet is already a 1.6-gallon model from the last 25 years, the water savings are small and you should not count them.
What a 20 percent toilet paper price rise does to the timeline
It shortens every payback by about a sixth. At $240 a year instead of $200, the paper-dry family saves $99 net and the dryer family saves $171 net, and the ST-01's premium over a standard toilet pays back in 4 to 9 years instead of 5 to 12. A 20 percent price rise takes a year or two off the wait. The buyer it makes sense for stays the same.
Are Bidets Themselves Tariff-Exposed?
Yes, and that is the part of the story the tariff headlines skip. Most bidet attachments and electric seats sold in the US are manufactured in China or South Korea, and their prices have already moved: Tushy's Cloud model went from $359 to $500 in early 2025 in a round of tariff-driven increases that r/bidets tracked in real time. If you are planning to buy a seat, the price you see today is not guaranteed to be there in October.
What we can say is what the ST-01 warranty covers: the porcelain for life, the electronics for three years, with a full replacement in the first year. A seat with a six-to-nine-year expected life that you replace at a higher tariff price in year seven is a different ten-year total than a bowl that stays put. Warranty is also the fastest way to sort the rest of the market, which is why we compared the major smart toilet brands on warranty length rather than on features.
What You Are Actually Buying (and What Doctors Say)
You are buying cleanliness, warm water, and the end of a monthly errand, and the savings are the part that makes it easy to say yes. The most-repeated line in every forum we read was some version of "I do not like using a toilet without one any more." The hygiene-first camp on Quora goes further: "cost savings is irrelevant." We think that is the honest way to see an integrated smart toilet. The heated seat, the automatic lid, the dryer, and the self-cleaning nozzle are what you pay $1,290 for. The paper is what you stop paying for.
On the medical side, be careful with anyone who promises health benefits. A 2022 systematic review from the University of Saskatchewan's Department of Surgery, published in Evidence-Based Complementary and Alternative Medicine, pooled six studies on habitual bidet use and found no change in the odds of developing hemorrhoids, found bidets no worse than sitz baths for pain after hemorrhoid surgery, and flagged a possible link between heavy use and anal itching, mostly in men. The takeaway is that a bidet is a comfort and hygiene device with no strong evidence for or against it medically. If you have a specific condition, ask your doctor and keep the water pressure low.
Who Should Not Buy a Smart Bidet Toilet for the Savings
Do not buy an integrated smart toilet to save money on toilet paper if any of these describe you. Buy the tier that fits instead.
- If you rent, a $40 attachment installs in 15 minutes with a wrench and comes with you when you move. It pays for itself before your next lease renewal.
- If you live alone or as a couple, you spend $40 to $110 a year on paper, and a seat or an integrated toilet will not pay back on paper inside a decade. Buy them for the warm water and the dryer, or buy the attachment.
- If your toilet is in good shape and you have an outlet, the electric seat gets you warm water and most of the savings for a third of the price.
- If you plan to wipe first and rinse second, you will love the cleanliness and the paper bill will not move.
- If your bathroom has no outlet and no remodel planned, buy a cold attachment now and call the electrician later, if ever.
Say you are a couple in a 1990s condo with a working 1.6-gallon toilet and an outlet behind the vanity. The right answer is a $400 seat, and it pays back in about four years. Now say you are the same couple, but the toilet is cracked, the bathroom is being redone, and one of you has a bad back that makes bending to lift a lid a real problem. Now the ST-01's automatic lid, heated seat, and dryer are the reason, the paper savings are a bonus, and the premium over the standard toilet you were about to buy anyway is the only number that matters.
Four steps to decide:
- Count your household and check your toilet's flush rating, printed inside the tank or on the bowl behind the seat. Under 1.6 gallons means no water savings to count.
- Decide how you will dry. Towel or dryer puts you in the 90 percent tier. Paper puts you in the 60 percent tier. Be honest about the kids.
- Check for an outlet within three feet of the toilet. None, and no remodel coming, means the attachment.
- If you are replacing the toilet in the next year, price the ST-01 against a standard toilet plus a seat, not against zero, and buy it for the features or not at all.
Do that and you will have a number before the September 8 tariff date. A year from now, whichever tier you chose, you will be buying toilet paper about once, and the price on the shelf will be somebody else's problem.
FAQs
Is it cheaper to use a bidet or toilet paper?
A bidet is cheaper over any period longer than a few months. A wash costs about an eighth of a gallon of water, a fraction of a cent, while a big roll of toilet paper costs $0.80 to $1.10 and the average person uses about 50 of them a year. Even a heated smart toilet's $35 to $65 a year in electricity is less than what a two-person household spends on paper.
Do I still wipe after using a bidet?
Most people pat dry with a few squares or a towel, and some check with paper. You do not wipe to clean; the water does that. Households that pat dry with paper cut use by 50 to 70 percent, and households that use a towel or a warm-air dryer cut it by 90 percent or more.
Do bidets run up your water bill?
No. A family of four using a bidet twice a day each adds roughly 365 gallons a year, about $2 to $4 at typical municipal rates. Replacing a pre-1994 toilet with a 1.28-gallon WaterSense model saves far more water than the bidet uses.
How much electricity does a heated bidet seat use per year?
Between about 100 and 350 kilowatt-hours, or $18 to $64 at the June 2026 US average rate of 18.3 cents per kilowatt-hour. The low end is a seat with an occupancy sensor or eco mode, the high end is a seat left at full heat around the clock. Tankless water heating adds about $11 a year for a family of four.
How long does a bidet take to pay for itself?
A $40 attachment pays back in four to six months for a family of four. A $300 to $500 electric seat takes about three to six years. A $1,290 integrated smart toilet takes 9 to 17 years at full price, or 5 to 12 years on the premium over a standard toilet you were buying anyway, with the shorter end for households that dry with the built-in dryer.
How much toilet paper does a bidet save a month?
For a family of four buying about 17 big rolls a month, a bidet with paper drying saves 8 to 12 rolls a month and a bidet with a dryer or towel saves 15 or more. In dollars, that is roughly $8 to $15 a month, or $100 to $200 a year, before any tariff increase.
Is there a downside to using a bidet?
The real downsides are cold water on cheap attachments, weak dryers on cheap seats, the outlet a heated unit needs, and guests who will not use it. Medically, a 2022 systematic review found no strong evidence for or against habitual bidet use, with a possible link between heavy use and anal itching. Keep the pressure low and you avoid most of it.
Will the Canada tariff make bidets more expensive too?
Most bidet seats and attachments are made in China or South Korea and have already had tariff-driven price increases, including Tushy's move from $359 to $500 in 2025. Check where a unit is manufactured before assuming today's price holds through the fall.

Replacing a Toilet Anyway? Look at the Badeloft ST-01
The toilet paper math is the easy part. The hard part is choosing a toilet you will still be glad about in year ten, when the tariff is a trivia question. The ST-01 is one ceramic bowl with tankless warm water, a heated seat, a warm-air dryer, an automatic lid, and a self-cleaning UV nozzle built in, with a lifetime warranty on the porcelain and three years on the electronics. If you are replacing a toilet this year, see the Badeloft smart toilet and price it against what you were going to buy anyway.
