Thinking about upgrading your bathroom with a bidet—but unsure what it’ll cost to get it professionally installed? You’re not alone. Many U.S. homeowners are embracing bidets for hygiene, comfort, and eco-friendliness, but the question remains: how much does a plumber cost to install a bidet? In this guide, we’ll break down real-world pricing, hidden factors that affect your bill, and smart ways to avoid overpaying—all while ensuring a safe, code-compliant installation.
What’s the Average Cost to Hire a Plumber for Bidet Installation?
The national average cost to hire a licensed plumber to install a bidet in the U.S. ranges from $150 to $600, according to data from HomeAdvisor and Angi (2025). However, your actual cost depends heavily on:
- Type of bidet (attachment vs. integrated toilet seat vs. standalone unit)
- Existing plumbing setup
- Geographic location
- Whether additional plumbing work is needed
For example:
- A basic bidet attachment (cold water only) might cost $75–$150 in labor.
- A smart bidet seat with heated water and drying functions typically runs $200–$400 in installation fees.
- A standalone bidet fixture (like those in Europe) can push labor costs to $500–$800+, especially if new water lines or floor drains are required.
💡 Pro Tip: Always confirm whether your quote includes parts, permits (if needed), and disposal of old fixtures.
Types of Bidets & Their Installation Complexity
Not all bidets are created equal—and neither are their installation needs. Here’s a quick comparison:
| Bidet Type | Installation Difficulty | Typical Labor Cost | Plumbing Changes Needed? |
|---|---|---|---|
| Bidet Attachment | Low | $75–$150 | Minimal (T-valve on existing supply) |
| Electric Bidet Seat | Medium | $200–$400 | GFCI outlet + hot/cold water access |
| Standalone Bidet Fixture | High | $500–$800+ | New water line, drain, possibly floor work |
Most U.S. homeowners opt for electric bidet seats (like Toto Washlet or Bio Bidet), which replace your existing toilet seat and connect to your home’s water supply and electrical system. These require both plumbing and electrical know-how—so hiring a plumber who’s comfortable with minor electrical work (or coordinating with an electrician) is key.
⚠️ Safety Note: Installing an electric bidet near water requires a GFCI (Ground Fault Circuit Interrupter) outlet to prevent shock hazards. Never skip this—it’s required by the National Electrical Code (NEC).
What Factors Influence Your Total Installation Cost?
Several variables can swing your final bill up or down:
1. Location, Location, Location
Labor rates vary widely by state. For example:
- New York or California: $80–$120/hour
- Texas or Florida: $60–$90/hour
- Rural Midwest: $45–$70/hour
Urban areas often charge more due to higher overhead and demand.
2. Access to Water Lines & Electrical Outlets
If your toilet is far from a shutoff valve or lacks a nearby GFCI outlet, you’ll pay extra for rerouting pipes or installing new wiring.
3. Permits and Inspections
While rare for simple bidet seat installs, standalone bidet installations may require plumbing permits in some municipalities—adding $50–$150 to your total.
4. Emergency or Weekend Service
Need it done fast? After-hours or same-day service can add a 20–50% surcharge.
Can You Install a Bidet Yourself? (And Should You?)
Many bidet attachments and even smart seats are marketed as “DIY-friendly.” And yes—you can install a basic model yourself in under 30 minutes using common tools.
Basic DIY Steps for a Bidet Seat:
- Turn off water supply and flush toilet to empty tank.
- Remove existing toilet seat.
- Install T-valve on toilet’s water supply line.
- Connect bidet hose to T-valve and bidet inlet.
- Mount new bidet seat onto toilet bowl.
- Plug into GFCI outlet (for electric models).
- Turn water back on, check for leaks, test functions.
However, call a plumber if:
- You’re unsure about water pressure or pipe compatibility
- Your home has older galvanized pipes (prone to leaks when disturbed)
- You need a new electrical outlet installed
- Local codes require licensed work
📌 According to a 2024 study by the National Association of Home Builders (NAHB), 68% of plumbing-related water damage claims stemmed from DIY projects gone wrong. When in doubt, hire a pro.

How to Save Money Without Sacrificing Safety
Want to cut costs but still get a reliable install? Try these strategies:
- Bundle services: If you’re already having a plumber for another job (e.g., fixing a leak), ask them to install the bidet during the same visit—many offer discounted rates for add-ons.
- Buy your own bidet: Some plumbers mark up fixtures. Purchase your preferred model online (e.g., Amazon, BidetKing) and only pay for labor.
- Schedule mid-week: Avoid weekends and holidays when labor rates spike.
- Get 3 quotes: Use platforms like Angi, Thumbtack, or local Facebook groups to compare transparent pricing.
FAQ Section
Q1: How long does it take a plumber to install a bidet?
A: Most bidet seat installations take 30–90 minutes. Standalone units may take 3–6 hours, depending on plumbing modifications.
Q2: Do I need an electrician to install a smart bidet?
A: Only if there’s no GFCI outlet within 3–4 feet of the toilet. Many plumbers partner with electricians or can recommend one. Never use an extension cord—it’s a fire hazard.
Q3: Will installing a bidet increase my water bill?
A: Slightly—but not significantly. A typical bidet uses ⅛ to ¼ gallon per use, compared to 1.6+ gallons per toilet flush. Over time, you may even save water by reducing toilet paper use.
Q4: Are bidet installations covered by home warranties?
A: Generally, no—unless it’s part of a covered plumbing repair. Home warranties rarely cover upgrades or new installations.
Q5: Can any toilet support a bidet seat?
A: Most standard elongated or round toilets can. Check your bidet’s compatibility chart before buying. Wall-mounted or specialty toilets may require adapters.
Q6: Is a permit required to install a bidet?
A: For non-electric attachments or replacement seats, usually no. But for permanent fixtures with new drains or water lines, check with your local building department—permits may be required in states like California or New York.
Conclusion

On average, between $150 and $600—but smart planning can help you stay on the lower end without risking leaks, code violations, or electrical hazards.
