A bidet can cost as little as a $20 spray attachment or as much as a $5,000-plus smart toilet. The right price for you comes down to one question: how much comfort and how many features do you actually want?
The good news is that you do not have to spend a lot to get a clean, comfortable rinse. Simple add-on bidets that clip onto the toilet you already own start around $20 to $40, while high-end electric seats and all-in-one smart toilets sit at the top of the range.
Below we break down what each type costs, what you will pay to install it, and what it costs to run month to month. Spoiler: most bidets pay for themselves in toilet-paper savings, often within the first year.

Handheld and Portable Bidets: $10–$40
These are the cheapest way to try a bidet. A handheld sprayer mounts to the wall next to your toilet and connects to the water line, while a portable bidet is a squeeze bottle with a nozzle you fill and take anywhere. Both are great budget or travel options, though they take a little practice and do not offer warm water.
Non-Electric Bidet Attachments: $30–$120
This is the most popular pick for first-time buyers. An attachment slides under your existing toilet seat and adds a clean-water rinse nozzle you control with a simple dial, with no electricity needed. Basic cold-water models run $30 to $60, while dual-nozzle and warm-water versions (fed from your sink's hot line) reach $80 to $120.
Electric Bidet Seats: $150–$800
These replace your toilet seat entirely and plug into an outlet to power heated water, a warm-air dryer, a heated seat, and adjustable spray settings. Entry-level electric seats start around $150 to $300, while premium models with remotes, air deodorizers, and auto features run $400 to $800. This tier is the sweet spot for everyday comfort.
Integrated Smart Toilets: $600–$8,000+
An integrated smart toilet is an all-in-one unit where the bidet, heated seat, and toilet are a single fixture. Mid-range smart toilets start around $600 to $2,000, and luxury models from brands like Toto and Kohler with self-cleaning, auto lids, and night lighting run $4,000 to $8,000 or more. These are typically chosen during a full bathroom remodel.
Installation: Free DIY or $130–$600 for a Pro
Most attachments and seats install in 15 to 30 minutes with just an adjustable wrench, so DIY is genuinely free. The main extra cost is power: electric bidets need a grounded GFCI outlet within about four feet, and if your bathroom lacks one, an electrician will charge roughly $130 to $300 to add it. A plumber for a full standalone or smart-toilet install typically runs $150 to $600 in labor.
Running Costs vs. Toilet-Paper Savings
Day-to-day operating cost is tiny: water adds only a dollar or two per person each year, and an electric seat's heating and drying add about $1 to $4 a month in electricity. Meanwhile, a family of four typically cuts toilet-paper spending by $200 to $300 a year, so even a cheap bidet usually pays for itself in 2 to 12 months.
Tips & warnings
- If you just want to try a bidet, start with a $30–$60 non-electric attachment before spending on an electric seat.
- Want warm water without paying for electricity? Pick an attachment that connects to your sink's hot-water line.
- Before buying an electric seat, check that you have a GFCI outlet near the toilet, or budget for an electrician.
- Measure your toilet (round vs. elongated, one-piece vs. two-piece) so the seat or attachment fits the first time.
Frequently asked questions
What is the cheapest type of bidet?
A handheld sprayer or portable squeeze bottle is the cheapest, often $10 to $40. The next step up is a non-electric attachment at $30 to $120, which is the most popular budget pick and installs in minutes.
Do I need an electrician to install a bidet?
Only for electric models. Handheld bidets, non-electric attachments, and basic seats need no power and install with a simple wrench. Electric seats and smart toilets need a grounded GFCI outlet nearby; if you do not have one, expect to pay an electrician about $130 to $300 to add it.
How much does a bidet cost to run each month?
Very little. The water used per rinse is a fraction of a gallon, adding only a dollar or two per person per year. Electric seats that heat water and air add roughly $1 to $4 a month in electricity, depending on use and whether the energy-saver mode is on.
Do bidets actually save money?
Yes, for most households. A four-person home commonly saves $200 to $300 a year on toilet paper. Against that, a $40 attachment often pays for itself in 2 to 4 months, and even a mid-range electric seat usually breaks even within a year or two.
Is a $500 electric seat worth it over a $50 attachment?
It depends on what you value. A $50 attachment delivers a clean rinse and the same toilet-paper savings. The extra money on an electric seat buys comfort features: heated water, a warm-air dryer, a heated seat, and a remote. If those matter to you, it is worth it; if you only want clean and cheap, the attachment wins.
