TL;DR
Bidet attachments cost $25 to $75 upfront with near-zero running costs. Electric bidet seats run $200 to $700 plus about $3 to $5 per month in electricity. Smart toilets start at $1,500 and can exceed $10,000. When you factor in toilet paper savings of $100 to $180 per year, most bidets pay for themselves within 3 to 18 months.
You know a bidet will save you money on toilet paper. But how much does the bidet itself actually cost? And what about electricity, water, installation, and maintenance?
The answer depends on which type you choose. A basic attachment can cost less than a month of toilet paper, while a high-end smart toilet can run more than a used car. This guide breaks down every cost you will encounter, from the purchase price to the 3-year total cost of ownership, so you can make a decision that fits your budget.
How Much Does a Bidet Cost by Type
Bidet prices fall into four distinct tiers. Each tier comes with different features, different installation requirements, and different ongoing costs.
Non-Electric Bidet Attachments: $25 to $75
These are the most affordable way to start using a bidet. An attachment is a slim panel that installs between your existing toilet seat and the bowl. It connects to your toilet's water supply line with a T-valve and uses water pressure to power the spray.
Popular models and their prices:
- BioBidet SlimEdge — around $25 to $30. Single rear wash nozzle, adjustable pressure, ultra-slim design.
- LUXE Bidet NEO 185 — around $35 to $45. Dual nozzles (rear and feminine wash), self-cleaning mode.
- TUSHY Classic 3.0 — around $60 to $75. Rear and front wash, pressure control knob, sleek design with color options.
- Brondell SimpleSpa SS-150 — around $35 to $45. Single nozzle, retractable spray head, simple dial control.
What you get: A clean, effective wash with adjustable water pressure. Some models include dual nozzles for rear and front wash.
What you give up: Warm water (unless your toilet is near a hot water line), heated seats, air dryers, and remote controls.
Installation cost: $0. Every attachment includes all necessary hardware. You need a wrench and 15 minutes.
Electric Bidet Seats: $200 to $700
Electric bidet seats replace your existing toilet seat entirely. They plug into a GFCI outlet and unlock comfort features that attachments cannot match.
Popular models and their prices:
- TOTO Washlet C5 — around $400 to $450. Warm water, heated seat, warm air dryer, PREMIST bowl spray, night light, wireless remote.
- Brondell Swash 1400 — around $400 to $500. Stainless steel nozzle, infinite warm water (instant heating), deodorizer, slow-close lid.
- BioBidet BB-2000 Bliss — around $350 to $450. Hybrid water heating, oscillating wash, wireless remote, energy-saving mode.
What you get: Warm water with adjustable temperature, a heated seat, a warm air dryer, adjustable nozzle position, self-cleaning nozzles, and often a wireless remote.
What you give up: Nothing functionally. The tradeoffs are higher upfront cost and the need for a nearby electrical outlet.
Installation cost: $0 if you already have a GFCI outlet within 4 feet of the toilet. If you need an outlet installed, expect to pay $150 to $300 for an electrician.
Smart Toilets: $1,500 to $10,000+
Smart toilets integrate the bidet directly into the toilet bowl and seat, creating a single seamless unit.
Popular models and their prices:
- Entry-level smart toilets — $1,500 to $3,000. Basic bidet functions integrated into a modern toilet design.
- TOTO Neorest NX1 — $4,000 to $6,000. eWater+ nozzle sterilization, auto open/close, auto flush, tankless instant heating, actilight self-cleaning bowl.
- Premium models — $6,000 to $10,000+. Top-tier designs with every conceivable feature and premium materials.
What you get: Everything an electric seat offers, plus a sleeker design, automatic lid operation, auto-flush, and often more powerful wash performance.
What you give up: A lot of money. Installation usually requires a plumber ($200 to $500), and repairs cost more since the bidet and toilet are one unit.
Installation cost: $200 to $500 for professional plumber installation. Some models require electrical work as well.
Portable and Travel Bidets: $10 to $40
If you want to try a bidet before committing or need one for travel, portable bidets are the cheapest option.
- Manual squeeze bottles — $8 to $15. Simple, no batteries needed.
- Brondell GoSpa — around $13. Ergonomic squeeze design, travel case included.
- Battery-powered portable bidets — $25 to $40. Electric pump for consistent pressure.
These are not permanent solutions, but they are a low-risk way to experience bidet cleansing before investing in a home unit.
Running Costs: What You Will Pay After the Purchase
The sticker price is only part of the story. Here is what each bidet type costs to operate.
Water Usage
All bidets use surprisingly little water. A typical bidet uses about one-eighth of a gallon (0.5 liters) per use. At an average of 5 uses per day, that is about 0.6 gallons daily or roughly 220 gallons per year.
Annual water cost: $1 to $3 per person.
For context, a single toilet flush uses 1.6 gallons. Your bidet's water usage is a rounding error on your water bill.
Electricity (Electric Seats and Smart Toilets Only)
Electric bidet seats draw power for water heating, seat heating, and the air dryer. Most models consume 300 to 500 watts during active use, with standby consumption of 10 to 30 watts for seat heating.
Monthly electricity cost: $3 to $5 at average U.S. electricity rates (about $0.16/kWh).
Many modern electric seats include eco modes or programmable schedules that reduce standby power. The TOTO Washlet C5, for example, can learn your usage patterns and only heat the seat when you are likely to use it.
Annual electricity cost: $36 to $60.
Toilet Paper Savings
This is where bidets start paying for themselves. The average American uses about 100 rolls of toilet paper per year, costing $50 to $90 per person depending on the brand.
Bidet users typically reduce toilet paper usage by 75% to 90%. Most people still use a few sheets to pat dry (unless they use the air dryer), but the reduction is dramatic.
Annual toilet paper savings per person: $40 to $80. Annual savings for a household of two: $80 to $160. Annual savings for a household of four: $160 to $320.
Maintenance and Replacement Parts
- Non-electric attachments: No ongoing parts costs. Replace the unit every 3 to 5 years ($25 to $75).
- Electric bidet seats: Some models use replaceable deodorizer cartridges ($10 to $30 per year). Water filters on certain models run $15 to $25 per year. Replace the seat every 5 to 10 years.
- Smart toilets: Similar consumable costs to electric seats. Professional servicing if needed ($100 to $300 per visit, though rarely required).
3-Year Total Cost of Ownership Comparison
Here is the full picture. This table compares what you will actually spend over three years, including purchase price, installation, running costs, and toilet paper savings for a household of two.
| Cost Category | Attachment | Electric Seat | Smart Toilet |
|---|---|---|---|
| Purchase price | $35 to $75 | $350 to $500 | $3,000 to $6,000 |
| Installation | $0 | $0 to $300 | $200 to $500 |
| Electricity (3 years) | $0 | $108 to $180 | $108 to $180 |
| Water (3 years) | $6 to $9 | $6 to $9 | $6 to $9 |
| Maintenance (3 years) | $0 | $30 to $75 | $30 to $75 |
| Total 3-year cost | $41 to $84 | $494 to $1,064 | $3,344 to $6,764 |
| TP savings (3 years, 2 people) | −$240 to −$480 | −$240 to −$480 | −$240 to −$480 |
| Net 3-year cost | −$156 to −$439 | $14 to $824 | $2,864 to $6,524 |
The key takeaway: a bidet attachment actually saves you money within the first year. An electric bidet seat approaches breakeven within 2 to 5 years depending on the model and your household size. Smart toilets are a luxury investment that never pays for itself in toilet paper savings alone.
How Much Does a Bidet Cost Compared to Toilet Paper?
Let us put this in perspective. If you never buy a bidet and keep using toilet paper exclusively, here is what you will spend over time for a household of two:
- 1 year of toilet paper: $100 to $180
- 3 years of toilet paper: $300 to $540
- 5 years of toilet paper: $500 to $900
- 10 years of toilet paper: $1,000 to $1,800
A $35 bidet attachment with near-zero running costs replaces the vast majority of that spending. Over 10 years, the savings add up to $700 to $1,600 compared to toilet paper alone.
Even if you upgrade from an attachment to an electric seat after a year (a common path), your total spending over 10 years is still less than what you would have spent on toilet paper. For a deeper look at this comparison, check out our bidet vs. toilet paper analysis.
What Affects the Price of a Bidet?
Not all bidets within the same category cost the same. Here is what drives the price up or down.
Water Heating Method
- No heating (cold water only): Cheapest. Found on all attachments.
- Tank heating: A small reservoir heats water in advance. Cheaper electric seats use this, but you get limited warm water per session (30 to 60 seconds).
- Instant/tankless heating: Heats water on demand for unlimited warm water. Found on premium electric seats like the Brondell Swash 1400. Costs $50 to $150 more than tank-heated models.
Build Materials
- Plastic nozzles and housings: Standard on budget models. Functional but less durable.
- Stainless steel nozzles: More hygienic and longer-lasting. Found on mid-range and premium seats.
- Ceramic and premium materials: Smart toilets use higher-grade ceramics and finishes, which accounts for much of their premium pricing.
Features That Add Cost
- Wireless remote (+$30 to $80 vs. side panel controls)
- Deodorizer (+$20 to $50)
- Night light (+$10 to $20, often bundled with mid-range seats)
- Auto open/close lid (+$200 to $500, mostly found on smart toilets)
- UV or eWater+ nozzle sterilization (+$50 to $200)
Brand Premium
TOTO commands the highest brand premium in the bidet market, with prices 10% to 30% higher than comparable models from Brondell or BioBidet. You are paying for TOTO's reputation for reliability and build quality, which is deserved but does add to the cost. See how specific models stack up in our best electric bidet seats roundup.
Best Value Picks by Budget
Best Value Under $50: BioBidet SlimEdge
At around $25 to $30, the SlimEdge delivers a reliable rear wash with adjustable pressure. It is one of the thinnest attachments on the market, so it does not raise your seat height noticeably. Hard to beat for the price. See more picks in our best budget bidet attachments guide.
Best Value Under $100: TUSHY Classic 3.0
At $60 to $75, the TUSHY adds a front feminine wash, better aesthetics, and a smoother pressure control knob. It costs more than the absolute cheapest attachments, but the build quality and dual-nozzle design justify the premium for most buyers.
Best Value Under $500: TOTO Washlet C5 or Brondell Swash 1400
Both sit in the $400 to $500 range and deliver the features that matter most: warm water, heated seat, air dryer, and wireless remote. The Swash 1400 edges ahead on unlimited warm water (instant heating), while the C5 wins on TOTO's build quality and PREMIST bowl-cleaning spray.
Best Value Over $500: BioBidet BB-2000 Bliss
At $350 to $450, the BB-2000 Bliss is actually under $500 but competes with seats that cost significantly more. It includes oscillating wash, a stainless steel nozzle, and a wireless remote. One of the strongest value propositions in the electric seat category.
The Bottom Line on Bidet Costs
A bidet does not have to be expensive. A $30 attachment gives you the core benefit — a water wash that is cleaner and more hygienic than toilet paper — and pays for itself within months.
If you want comfort features like warm water and a heated seat, expect to spend $300 to $500 for an electric seat that will last 5 to 10 years. That works out to roughly $4 to $8 per month, which is less than most people spend on toilet paper.
Smart toilets are beautiful and feature-rich, but they are a luxury. Unless you are remodeling your bathroom and want the cleanest look possible, an electric seat delivers the same daily experience at a fraction of the cost.
Whatever your budget, the math favors the bidet. Start with what you can afford, and upgrade later if you want. Most people never go back to toilet paper alone.
