Thinking about adding a bidet to your bathroom but unsure if you’ll need to call a plumber? You’re not alone. Millions of Americans are switching to bidets for hygiene, comfort, and sustainability—but the big question remains: Do I need a plumber to install a bidet? The good news? In many cases, you don’t. But it depends on your setup, skill level, and the type of bidet you choose. Let’s break it down so you can make a confident, cost-effective decision.
What Types of Bidets Are Available?
Before deciding whether you need professional help, understand your options. Bidets fall into four main categories:
- Bidet Attachments (Non-Electric)
Simple, affordable, and attach directly under your existing toilet seat. No electricity required. - Bidet Seats (Electric)
Replace your current toilet seat with a feature-rich model (heated water, warm air dry, remote control). Requires an electrical outlet nearby. - Standalone Bidets
A separate fixture next to your toilet—common in Europe but rare in U.S. homes. Requires major plumbing work. - Smart Toilets with Built-in Bidet
All-in-one units with flushing, bidet, and drying functions. High-end and complex to install.
💡 Key Insight: Over 70% of U.S. bidet buyers opt for non-electric attachments or electric seats due to ease of installation (Statista, 2024).
Can You Install a Bidet Yourself?
Yes—in most cases. If you’re installing a non-electric bidet attachment or even an electric bidet seat, you likely won’t need a plumber—especially if you’re comfortable with basic tools.
When DIY Works Best:
- Your toilet has a standard two-piece design (tank + bowl).
- You have access to the water supply valve behind the toilet.
- For electric models: a grounded GFCI outlet is within 3–4 feet (required by U.S. electrical code).
According to the Plumbing-Heating-Cooling Contractors Association (PHCC), over 60% of minor bathroom upgrades like bidet attachments are successfully completed by homeowners without professional help.
Step-by-Step: How to Install a Non-Electric Bidet Attachment
No plumber? No problem. Here’s how to install a basic bidet attachment in under 30 minutes:
- Turn off the water supply
Locate the shut-off valve behind the toilet. Turn it clockwise until tight. - Flush the toilet
This drains remaining water from the tank and lines. - Remove the existing toilet seat
Unscrew the two bolts at the back of the seat using a wrench or screwdriver. - Attach the bidet T-valve
Connect the included T-valve to the fill valve (where the water hose enters the tank). Hand-tighten, then give a quarter-turn with pliers—do not overtighten. - Connect the bidet hose
Attach one end to the T-valve and the other to the bidet nozzle under the seat. - Reinstall the toilet seat (or new bidet seat)
Align the seat and tighten the bolts evenly to avoid cracking. - Turn water back on & test
Slowly open the shut-off valve. Check for leaks at all connections. Test the spray.
✅ Pro Tip: Use a small towel under connections during testing—catches drips before they become puddles.
When Should You Call a Plumber?
While many installations are DIY-friendly, certain situations require a licensed plumber:
| No accessible shut-off valve | Older homes may lack a valve behind the toilet. Installing one requires pipe work. |
| Hard water or corroded pipes | Risk of leaks or damage when disconnecting old fittings. |
| Electric bidet + no nearby outlet | Running new electrical lines must comply with NEC (National Electrical Code). |
| Wall-mounted or one-piece toilets | Limited access makes installation tricky or impossible without expertise. |
| You’re uncomfortable with tools | Better safe than sorry—water damage can cost thousands. |
🚨 Real-World Example: A 2023 HomeAdvisor report found that 22% of DIY plumbing mishaps involved toilet-related upgrades, with average repair costs exceeding $450.

Pros and Cons: DIY vs. Hiring a Plumber
| Cost | $0–$50 (tools you may already own) | $150–$400 (labor only) |
| Time | 20–60 minutes | 1–2 hours (including scheduling) |
| Risk | Minor leaks if done incorrectly | Virtually none (licensed pros guarantee work) |
| Warranty | May void bidet warranty if installed wrong | Often covered under service agreement |
| Peace of Mind | Great if confident | Essential if unsure |

“Most bidet attachments are designed for homeowners. But if your bathroom hasn’t been updated since the 1980s, get a pro to assess your plumbing first.”

Common Mistakes to Avoid
Even simple installs can go wrong. Watch out for:
- Overtightening plastic fittings → cracks and leaks.
- Ignoring the direction of the T-valve → blocks water flow to the tank.
- Skipping the leak test → hidden drips cause mold over time.
- Using extension cords for electric bidets → fire hazard (NEC prohibits this).
FAQ Section
Q1: How much does it cost to install a bidet with a plumber?
A: On average, plumbers charge $150–$400 for bidet installation, depending on location and complexity. Non-electric attachments are on the lower end; smart toilets cost more due to plumbing and electrical work.
Q2: Do bidets require special plumbing?
A: Non-electric models only need a cold water connection—which your toilet already has. Electric models need both water access and a GFCI electrical outlet within reach. No major plumbing changes are usually required.
Q3: Can I install a bidet on a one-piece toilet?
A: It depends. Some one-piece toilets have limited space between the tank and bowl, making T-valve installation difficult. Check your bidet manufacturer’s compatibility list first—or consult a plumber.
Q4: How long does bidet installation take?
A: DIY: 20–45 minutes. With a plumber: 30–90 minutes, including inspection and testing.
Q5: Will installing a bidet void my toilet warranty?
A: Generally, no—as long as you don’t modify the toilet itself. However, improper installation that causes damage may not be covered. Always follow the bidet manufacturer’s instructions.
Q6: Are bidets eco-friendly?
A: Absolutely! The average American uses 384 rolls of toilet paper per year. A bidet can reduce that by 75% or more, saving trees, water (used in TP production), and landfill waste.
Conclusion
So, do you need a plumber to install a bidet? For most people using standard toilets and choosing non-electric or plug-in electric models—no, you don’t. With basic tools and 30 minutes, you can enjoy cleaner, greener hygiene without calling a pro.
But if your home has older plumbing, no nearby outlet, or you simply value peace of mind, hiring a licensed plumber is a smart investment. Either way, you’re making a sustainable, health-conscious upgrade millions are embracing.
