How much does a bidet cost? Every type, with installation
A bidet costs about $20 to $150 for an under-seat attachment, $170 to $650 for an electric bidet toilet seat, and $1,000 or more for a bidet toilet. Installing an attachment yourself is free and takes about 20 to 30 minutes; a seat adds an outlet and possibly labor, bringing the all-in figure to $470 to $1,700 per Fixr. If you want the lowest cost to try one, an attachment is the answer, and the rest of this page shows what you get at each price and what the real total is.

The ranges below come from retailer listings, Angi's 2026 data, Fixr and roundups read on 2026-11-10. Prices change by retailer and by week, so they are bands, not quotes. Our own attachment isn't on sale yet and has no price here.

The word "bidet" covers all of these, so a search for the price returns very different numbers. When a price sounds too low or high, check which type it is. The 2026 roundups list basic non-electric attachments at about $20 to $60 and mid-range ones at about $60 to $180, with electric seats starting higher.

- Bidet toilet: a plumber, and often an electrician. Get quotes.
The costs people forget

| New GFCI outlet | Electric seats | $130 to $300 (US cost guides) |
| Backflow device where local rules require it | Some installs | Ask a local plumber; see backflow guide |

| Dry cloths or a towel | All | Optional; see drying without toilet paper |
Does a bidet pay for itself?
It can, but you should run it on your own numbers. Add up what you spend on toilet paper and wipes in a month, estimate the share a bidet would replace, and divide the purchase price by the monthly saving. We don't have a reliable published average of how much toilet paper people save, so we don't give a typical payback; bidet vs toilet paper shows the sum step by step, and are bidet attachments worth it covers who should skip one. The cost gap between a $40 attachment and a $400 seat is the bigger lever on payback than anything else.
A five-year view, using the ranges above
Spread over time, the numbers look different from the sticker. These are illustrations from the bands in this page, with no running costs because we have no reliable published figure for them.
| Choice | Up-front | Spread over five years |
|---|---|---|
| $40 attachment, DIY install | $40 | About $8 a year |
| $120 warm-water attachment, DIY | $120 | About $24 a year |
| $400 seat, DIY, outlet exists | $400 | About $80 a year |
| $400 seat, outlet added at $200, labor $150 | $750 | About $150 a year |
Hoses and washers wear before a seat's electronics do, which is why spare parts matter on an attachment, and why do bidets break easily is worth reading before any purchase. A seat's heater and electronics add things that can fail, and repairs on them cost more than a washer.
What each price level is like to live with
Under $30, expect a plain spray, a basic knob and a hose that can kink. If it leaks at the T-adapter, the four-joint check fixes most drips. At $30 to $60 you're in the sweet spot for a first purchase: braided hose, adjustable pressure, often a metal adapter. Between $60 and $130 you pay for finish, a slim plate that sits flat under your seat, and a brand that sells spares. An electric seat is a different life: warm water on demand, a heated seat and sometimes a dryer, in exchange for an outlet, a bigger purchase and more that can go wrong.
None of this is about being clean. Every type rinses; the price is about comfort, convenience and how long it lasts. That's why many people start with the cheapest decent attachment and only upgrade if they love it.
Which price level should you pick?
| If you… | Start at |
|---|---|
| Have never used a bidet | A $20 to $60 attachment with a braided hose and metal T-adapter |
| Rent | A removable attachment; see the renters' guide |
| Want warm water without an outlet | An attachment with a hot-line hookup |
| Want a heated seat and a dryer | An electric seat, with the outlet in the budget |
| Are remodeling | Ask a plumber about an outlet and a bidet toilet; see do bidets add value to a home |
If you aren't sure, spend less first. A first purchase at the low end tells you whether you'd use it, and the upgrade path is open.
How to avoid overpaying
- Compare on the same checks, not the same star rating: fit, adapter material, hose, returns.
- Be wary of "fits all toilets", a huge list price with a huge discount and reviews that all arrived at once.
- Buy where you can return it. Where to buy a bidet attachment compares store, online and direct.
- Don't pay for features you can't use, like a hot inlet with no sink near the toilet.
- Read what shoppers say first with bidet attachment reviews.
