Bidet Installation Cost: $400–$2,500 (Average $1,000) in 2026

Author: CostGuideHQ Editorial·✓ Fact-checked·Updated July 2026·7 min read·7 sources·US national averages, USD
Quick answerQuick answer: Most homeowners pay $400 to $2,500 to install a bidet, averaging around $1,000. A bidet seat or attachment costs far less than a standalone fixture or built-in bidet toilet. New electrical outlets and dedicated water lines are common add-ons that push the price up.
  • The typical bidet installation costs $400 to $2,500, averaging about $1,000 nationally (Fixr, Forbes Home).
  • A bidet attachment installs for $100 to $300, versus $500 to $1,500 for a standalone fixture and $1,200 to $2,000 or more for a built-in bidet toilet (HomeAdvisor, Fixr, Angi).
  • Electric bidet seats and smart bidet toilets often need a new GFCI outlet, adding $120 to $300 to the job (Fixr, Angi, HomeGuide).
  • A standalone bidet needs its own water supply line, adding roughly $300 to $600 in plumbing labor that an attachment or seat skips entirely (Forbes Home).

What affects the cost?

  • Fixture type — a bidet attachment installs for $100-$300, a bidet seat runs $170-$1,700, a standalone bidet fixture costs $500-$1,500, and an all-in-one bidet toilet runs $1,200-$2,000 or more (HomeAdvisor, Fixr, HomeGuide)
  • Electrical work — electric/heated bidet seats and smart bidet toilets need power at the fixture, so a new GFCI outlet adds $120-$300 (Fixr, Angi, HomeGuide) or roughly $200 in electrical wiring (Forbes Home)
  • Water line/plumbing work — a standalone bidet needs its own dedicated supply line, which runs about $300-$600 in professional plumbing labor (Forbes Home) or averages $1,180 for new plumbing lines (HomeAdvisor); attachments and seats simply tap into the existing toilet supply valve, so they skip this cost
  • Plumber labor rate — plumbers charge $45-$200 per hour (Angi, Fixr, HomeGuide), with total labor typically running $90-$600 for a job that takes 2-4 hours (Angi, HomeGuide)
  • Mounting type for standalone units — floor-mounted bidets run $1,200-$2,200 installed versus $1,500-$2,500 for wall-mounted, which needs more invasive plumbing work (Fixr)
  • Installation time and complexity — a bidet seat or attachment takes 15-30 minutes in most cases, while a standalone bidet or bidet toilet takes 2-4 hours (HomeGuide)
  • Brand and features — premium electric bidet toilets with heated seats, dryers, and smart controls push costs toward the top of the range (Forbes Home, Fixr, This Old House)

How much does it cost to install a bidet?

Most homeowners pay $400 to $2,500 to install a bidet, averaging around $1,000 (Fixr, Forbes Home). HomeAdvisor and Angi report a lower average of $640, with a typical range of $400 to $1,500, while Forbes Home’s figures run higher — average $1,090, range $400 to $2,500. The gap between sources comes down almost entirely to fixture type: a simple attachment costs a fraction of what a standalone bidet or built-in bidet toilet runs. HomeGuide, which focuses on standalone models with dedicated plumbing, puts that specific job at $700 to $2,600. Because “bidet installation” covers such different projects — from a $30 DIY attachment (Bob Vila) to a $5,000 smart bidet toilet (This Old House) — the type you choose matters more than any regional or contractor variable.

What’s the difference between a bidet seat, attachment, and standalone fixture?

Fixture type is the single biggest cost driver. A bidet attachment, which mounts under your existing toilet seat and taps into the toilet’s water supply, is the cheapest option at $100 to $300 installed (Fixr, HomeGuide) — Bob Vila puts a DIY version at as little as $30 to $500 in total project cost. A bidet toilet seat, which replaces your seat entirely and often adds spray controls, heating, or a dryer, costs $170 to $1,700 installed (HomeAdvisor, Angi, Fixr, Forbes Home); non-electric models sit at the low end, and electric ones with more features push toward the top. A standalone bidet — a separate fixture installed next to the toilet — runs $500 to $1,500 (HomeAdvisor, Angi, Fixr, Forbes Home), or up to $2,600 including dedicated plumbing (HomeGuide). An all-in-one bidet toilet, which replaces the toilet itself, costs $1,200 to $2,000 or more (HomeAdvisor, Angi, Fixr), with premium models reaching $2,500 to $5,000 (Forbes Home, This Old House).

What electrical and plumbing work does a bidet need?

Add-ons beyond the fixture itself explain a lot of the remaining spread. Electric bidet seats and smart bidet toilets need power at the fixture, so if there’s no outlet nearby, expect to pay $120 to $300 for a new GFCI outlet (Fixr, Angi, HomeGuide), or roughly $200 in electrical wiring (Forbes Home) — non-electric seats and basic attachments skip this cost entirely. On the plumbing side, attachments and seats simply connect to your toilet’s existing water supply valve, but a standalone bidet needs its own dedicated water line, which runs about $300 to $600 in professional plumbing labor (Forbes Home) or averages $1,180 for the full new-line installation (HomeAdvisor). Plumbers charge $45 to $200 per hour (Angi, Fixr, HomeGuide), and total labor for a standalone bidet or bidet toilet typically runs $90 to $600 across a 2 to 4 hour job, compared to just 15 to 30 minutes for a seat or attachment (HomeGuide).

How can I lower my bidet installation cost?

Choose a bidet attachment or non-electric seat over a standalone fixture or bidet toilet — fixture type alone is the difference between a $100 job and a $2,000+ one (HomeAdvisor, Fixr, Angi). Skip electric and smart features if you don’t need them; a non-electric seat or attachment avoids the $120 to $300 cost of adding a new GFCI outlet (Fixr, Angi, HomeGuide). If you do want a standalone bidet, ask your plumber whether a floor-mounted unit works for your layout — it runs $1,200 to $2,200 versus $1,500 to $2,500 for wall-mounted, which needs more invasive plumbing (Fixr). Have the outlet, water line, and fixture installed in the same visit rather than hiring separately, and get a couple of quotes, since plumber labor rates alone span $45 to $200 per hour between pros (Angi, Fixr, HomeGuide).

Prices vary by region, fixture brand, and how much new electrical or plumbing work your bathroom needs, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether a new outlet or water line is included before committing to a final number.

Frequently asked questions

How much does it cost to install a bidet?
Most homeowners pay $400 to $2,500 to install a bidet, averaging around $1,000 (Fixr, Forbes Home). HomeAdvisor and Angi report a lower average of $640 with a typical range of $400 to $1,500, while Forbes Home's average runs closer to $1,090 across a $400-$2,500 span — the gap mostly comes down to which type of bidet you install.
What's the cheapest way to add a bidet to my bathroom?
A bidet attachment is the cheapest option, installing for $100 to $300 (Fixr, HomeGuide) since it connects directly to your existing toilet and water supply valve with no new plumbing or electrical work.
How much does a bidet seat cost installed?
A bidet toilet seat runs $170 to $1,700 installed (HomeAdvisor, Angi, Fixr, Forbes Home). Non-electric seats sit at the low end, while heated, electric seats with dryers and remote controls push toward the top of that range.
How much does a standalone bidet cost?
A standalone bidet fixture costs $500 to $1,500 installed (HomeAdvisor, Angi, Fixr, Forbes Home), and HomeGuide puts the full installed cost, including dedicated plumbing, at $700 to $2,600. Floor-mounted units run $1,200 to $2,200, while wall-mounted units cost $1,500 to $2,500 because of the more invasive plumbing work (Fixr).
Do I need an electrician to install a bidet?
Only if you're installing an electric bidet seat or a smart bidet toilet — non-electric seats and attachments don't need power. A new GFCI outlet near the toilet typically costs $120 to $300 (Fixr, Angi, HomeGuide), or about $200 in electrical wiring (Forbes Home).
How much does a bidet toilet cost?
An all-in-one bidet toilet costs $1,200 to $2,000 installed (HomeAdvisor, Angi, Fixr), though Forbes Home's range runs to $2,500 and This Old House notes premium models can reach $5,000.
What does plumber labor cost for a bidet installation?
Plumbers charge $45 to $200 per hour (Angi, Fixr, HomeGuide), with total labor typically running $90 to $600 for a job that takes 2 to 4 hours. A standalone bidet's dedicated water line adds more time than a seat or attachment, which simply taps the existing supply valve.
Why do bidet cost estimates vary so much between sources?
National averages range from $640 (HomeAdvisor, Angi) to $1,090 (Forbes Home), and installed costs by type span $100 for a basic attachment up to $2,500 or more for a premium bidet toilet — the spread reflects which fixture type, and how much new electrical or plumbing work, each estimate assumes.

  • Forbes Home — Average cost $1,090, range $400-$2,500. By type (material + installation): bidet spray attachment $100-$300, bidet toilet seat $470-$1,700, standalone bidet $500-$1,500, bidet toilet $1,200-$2,500. Material only: spray attachment $40-$60, toilet seat $100-$1,000, standalone $200-$600, bidet toilet $1,000-$2,000. Plumbing installation about $300 to $600; electrical wiring another $200 or so.
  • This Old House — Standalone bidets $300-$600. All-in-one bidet toilets $500-$5,000, with most options between $1,000-$2,000. Bidet toilet seats $100-$1,000, with non-electric options typically under $100. Underseat bidet attachments $50-$100. Portable bidets $20-$50. Notes that installing the plumbing a standalone bidet fixture needs can make that option prohibitively expensive.

Sources cluster around two figures for the overall national average: HomeAdvisor and Angi both cite $640 (typical range $400-$1,500) — Angi Inc. owns both brands and republishes largely identical cost data across them — while Fixr cites $1,000 (range $500-$1,500) and Forbes Home cites $1,090 (range $400-$2,500). national_average_usd is anchored to Fixr's $1,000, which sits centrally between the HomeAdvisor/Angi and Forbes Home figures. range_low_usd ($400) is cited verbatim by three independent sources (HomeAdvisor, Angi, Forbes Home) as the low end of a typical project; range_high_usd ($2,500) is Forbes Home's typical-range high, close to HomeGuide's $2,600 ceiling for a standalone unit with dedicated plumbing. Note that a basic bidet attachment can cost less than the headline range low ($100-$300 installed, or as little as $30-$500 as a DIY project per Bob Vila) — the headline range describes a typical whole-project spend across all fixture types, not the cheapest option. by_type figures are installed totals: bidet attachment and standalone bidet each have three sources in exact agreement ($100-$300 and $500-$1,500 respectively, across Fixr/HomeGuide and HomeAdvisor/Angi/Fixr/Forbes Home); bidet seat spans widely ($170 HomeAdvisor/Angi low to $1,700 Fixr/Forbes Home high) because non-electric seats cost far less than heated, electric ones; bidet toilet uses the $1,200-$2,000 figure three sources agree on exactly (HomeAdvisor, Angi, Fixr), though Forbes Home's range runs to $2,500 and This Old House notes premium all-in-one bidet toilets can reach $5,000. Figures generally include the fixture and standard installation labor; a new electrical outlet and dedicated water supply line, when needed, are commonly quoted as separate add-ons.
