On the other hand, non-electric bidets are perfect for those looking for a simple, energy-efficient solution.

Factors Influencing Power Requirements

When considering the power requirements of a bidet, several factors come into play.

These factors can significantly influence the amount of electricity a bidet consumes.

Let’s delve into these factors to better understand the power dynamics of bidets.

Type of Bidet Seat

The type of bidet seat you choose plays a pivotal role in its power consumption:

  • Entry-Level Bidet Toilet Seats: These are budget-friendly and typically have a power rating ranging from 300-600 watts.
  • Mid-Range Electric Bidet Toilet Seats: Falling in an intermediate price range, these bidets have a power rating between 600-1000 watts.
  • High-End Luxury Bidet Toilet Seats: Being the most luxurious, they consume about 1000-1600 watts.

Frequency of Use

The more frequently you use the bidet, the higher its power consumption.

Larger families might notice a spike in their energy bills due to more frequent bidet usage, while smaller families or individuals might not see as significant an increase.

Available Features

Bidets come equipped with various features, and the more features a bidet has, the higher its power draw.

Features like a heated seat, remote control, adjustable water pressure, and tankless water heater all contribute to increased power consumption.

Feature Settings

The settings at which you use the bidet’s features can also influence its power draw.

For instance, if you prefer hotter water, the bidet will consume more power to heat the water to your desired temperature.

Number of Features Used

If you’re only using one feature of the bidet, its power consumption will be considerably lower than if you were to use multiple features simultaneously.

However, even when not in use, the bidet’s basic electrical outlet will still draw some power, albeit a negligible amount.

Electrical Considerations for Installation

When it comes to installing an electric bidet, there are several electrical considerations to keep in mind.

Ensuring that your bathroom is equipped with the right electrical setup is crucial for the safe and efficient operation of your bidet.

Let’s walk through these considerations step by step.

Outlet Requirements

Electric bidet seats typically require a standard 110-120V, 15 Ampere, 3-prong electrical outlet.

This is a common outlet found in most households.

However, the location of this outlet is crucial.

Bidet seats usually come with a 4-foot-long electrical cord.

Ideally, the outlet should be installed on the wall behind the toilet.

If your current outlet is too far from the bidet, consider using an extension cord or having a new outlet installed closer to the toilet.

Importance of GFCI Outlets

Safety first!

Bathrooms are damp environments, and the risk of electrical shocks is real.

That’s why it’s essential to have a GFCI (ground-fault circuit interrupter) outlet or an RCD (residual-current device) for your bidet.

These outlets have a built-in circuit breaker that offers protection against shocks if water enters the electrical outlet.

If your bathroom doesn’t already have a GFCI outlet near the toilet, it’s a good idea to hire an electrician to install one.

Dedicated Circuits: Are They Necessary?

While bidets don’t always need a dedicated circuit, it’s something to consider, especially in older homes.

If you have other high-power appliances running simultaneously on the same circuit as your bidet, you might run into issues.

For instance, in some older homes, having a bidet on a shared circuit with bathroom lighting could cause the lights to flicker or even trip the circuit.

To avoid such issues, it might be worth considering a dedicated circuit for your bidet, especially if you’re using a high-end model with multiple features.

Shared Circuit Concerns

When considering the installation of an electric bidet, especially in older homes or apartments, one of the primary concerns that arise is the potential risks associated with using the bidet on a shared circuit.

This concern is particularly relevant for those who live in apartments where modifying the circuitry isn’t an option.

Real-Life User Concerns

A user, going by the name mulletman13, shared their concerns on a Reddit post.

They mentioned having previously owned a basic attachment bidet in their old apartment.

Now, after moving, they’re keen on upgrading to one of the newer, more advanced models.

However, they face a dilemma.

The outlet next to their toilet is on a shared circuit with significant appliances like their microwave and refrigerator.

Their primary concern revolves around the power consumption of tankless bidets.

They’ve come across bidets with a max power consumption of around 660w.

Given their limited understanding of circuits, they’re unsure if their setup would be safe or if they’d constantly trip the breaker due to the bidet’s power draw.

Expert Insights

Responding to the user’s query, a commenter named ManyBidets pointed out that while a dedicated line isn’t strictly necessary, it’s essential to ensure that not much else is pulling on that shared line.

They mentioned that an instant water heating bidet could use about 13 amps at top pull.

So, if one has a 20 amp circuit, there’s some leeway.

However, appliances like fridges and microwaves also have a significant pull.

If all these devices are on the same line, potential issues could arise.

Another user, TexasDex, brought up the point about the microwave’s wattage.

They reasoned that if the microwave’s wattage is more than 700 (which is likely), and there aren’t constant issues with the microwave and fridge tripping the circuit, then the bidet’s addition might be manageable.

However, they also highlighted a potential problem with tanked bidets.

Since tanked bidets keep the water warm all the time, there’s no control over when they heat the water.

This could lead to potential circuit overloads if multiple high-wattage devices are operating simultaneously.

Key Takeaways

  • Shared Circuit Risks: Using a bidet on a shared circuit, especially with other high-power appliances, can pose risks of tripping the breaker.
  • Tankless vs Tanked: Tankless bidets might have a higher power draw, but tanked bidets can heat water unpredictably, adding to the circuit’s load.
  • Know Your Appliances: Being aware of the wattage and power draw of all appliances on a shared circuit is crucial to avoid overloading.

Cost Implications: The Dollar and Cents of Bidet Power

So, you’re all jazzed about bidets, huh?

You know they’re a game-changer for your bathroom routine, but let’s talk moolah.

How much is this luxury gonna cost you in electricity and water?

And hey, can it actually save you some dough?

The Electric Bill: What to Expect

Electric bidets are like tiny spa resorts for your tush, but they do need power.

The cost varies based on your settings and how many folks are using it.

For instance, a family of four cranking up the heat will pay more than a solo user who likes it lukewarm. 🌡️

  • High Usage Scenario: Around 18 cents per day, adding up to about $65.70 per year.
  • Low Usage Scenario: Just 6 cents a day, or roughly $21.90 annually.

And get this: newer bidet models are getting smarter.

They use tankless water heating and energy-saving modes.

So, you could end up spending even less. 🤑

Bidets can make that a thing of the past.

You’ll use way less toilet paper, which is not just good for your wallet but also for Mother Earth. 🌍

Water: A Drop in the Bucket

Bidets use a tiny stream of water, like half a liter per minute.

Even if you’re a bidet enthusiast and use it for 20 minutes a day, that’s just 10 liters.

Compared to old toilets that gulp down gallons, this is peanuts. 🚰

  • Annual Water Cost: A measly $1.93.

Yep, you read that right.

The Overall Picture: Is a Bidet Worth It?

So, let’s do some quick math.

On average, you’re looking at about 12 cents per day or around $45.73 per year for both electricity and water.

Now weigh that against the cost of toilet paper, and you might just find that a bidet isn’t a splurge—it’s an investment.


In the grand scheme of bathroom luxury, bidets are the unsung heroes, blending comfort with conservation.

From the tech-savvy electric versions to the humble non-electric ones, they offer a tailored experience for every tush.

But when it comes to power, it’s clear: bidets are efficient, economical, and environmentally friendly.

So, the next time you ponder about the power play of bidets, remember—they’re not just a luxury, they’re a smart choice.

Power up your bathroom, reduce your carbon footprint, and embrace the bidet revolution.
