Typical Project Cost by Bidet Type
National average pricingSame default project size (default scope), priced across each material tier.
| Tier | Material rate | Total project | Installed per unit |
|---|---|---|---|
| Basic non-electric attachment | $59.82 | $528 | $528 |
| Electric bidet seat | $349 | $817 | $817 |
| Premium smart bidet seat | $897 | $1,365 | $1,365 |
| Integrated smart toilet / washlet | $1,795 | $2,263 | $2,263 |
| Standalone bidet fixture | $1,396 | $1,864 | $1,864 |
Material rates reflect the latest BLS construction PPI adjustment. Installed totals include labor and supplies but exclude permits and any tear-out beyond the calculator's default scope.

The PPI is the wholesale price of materials and labor that contractors pay, before margin. A rising index usually flows into homeowner quotes within 2–4 months. Use this trend to decide whether to pull a project forward or wait.

Typical Cost Snapshot
For a typical bidet installation scenario in the national baseline, this calculator currently models a total around $817, or about $817 per unit.
This market is currently modeled close to the national baseline, so project swings are more likely to come from scope and finish choices than from regional pricing alone.
Local labor conditions, permit timing, and finish selection all influence how this project prices in your market.
Low / Mid / High Project Scenarios
Low Scenario
$234$234 per square foot
Single basic non-electric bidet attachment with simple tee adapter and no outlet.
Mid Scenario
$819$819 per square foot
Electric bidet seat with new supply line, nearby GFCI outlet, and standard elongated toilet fit.
High Scenario
$3,485$1,743 per square foot
Two premium smart bidet seats on skirted toilets with new dedicated circuit and minor finish adjustments.
What Changes the Estimate Most?
- Bidet type drives equipment cost, from a basic attachment under $100 to smart seats and integrated toilets above $1,000.
- Electrical work is often the deciding factor because electric seats need a nearby GFCI outlet, and many toilets do not have one.
- Standalone bidets are much closer to a mini bathroom rough-in than a seat install because they require separate drain and supply plumbing.
When This Calculator Is Less Accurate
This calculator is less accurate when the project includes wall-hung toilets, concealed carrier systems, full bathroom rewiring, standalone bidet drain rough-ins through concrete slabs, or luxury smart toilet swaps that require flooring and flange relocation.
Use the result as a budgeting starting point, then validate with local contractor quotes if the scope includes specialty materials, hidden damage, or permit-driven design changes.
How Much Does Bidet Installation Cost?
Bidet installation can cost under $200 for a simple non-electric attachment and $500-1,500 for an electric bidet seat with a new GFCI outlet. Integrated smart toilets and standalone bidets cost more because they add fixture replacement, plumbing rough-in, electrical work, and possible floor or wall repair.
Cost Factors:
- Bidet type drives equipment cost: attachments are inexpensive, while smart seats and integrated toilets include heated water, dryers, sensors, and controls
- Electric bidet seats usually need a GFCI outlet close to the toilet; many bathrooms do not already have one
- Older shutoff valves, rigid supply lines, and tight toilet alcoves add plumbing time
- Round, compact, skirted, and one-piece toilets can limit seat compatibility or require special brackets
- Standalone bidets are effectively a small bathroom plumbing project with rough-in, drain, supply, and finish work
Frequently Asked Questions (3)
How much does bidet installation cost?
A basic attachment can be installed for $75-200 if the toilet valve is accessible. Electric bidet seats commonly cost $500-1,500 installed when a GFCI outlet is added. Standalone bidets and smart toilets can cost $2,000-5,000+ installed.
Do electric bidets need an outlet?
Yes. Heated seats, warm water, dryers, night lights, and remote controls require power. Bathrooms typically need a GFCI-protected outlet within reach of the seat's cord, not an extension cord.
Will a bidet seat fit my toilet?
Most elongated two-piece toilets accept standard bidet seats. Round, skirted, compact, wall-hung, and one-piece toilets need compatibility checks before purchase because bolt spacing, bowl shape, and tank clearance can block the seat.
Data sources & methodology
Estimates blend national base costs, the BLS residential construction PPI, regional and direct metro CPI series, BLS OEWS state labor wages, and U.S. Census ACS housing signals. Market data refreshed June 2026. Expect ±15–30% spread vs an actual contractor quote.
