How Much Electricity Does a Bidet Use?

When you buy an electric bidet or an electric bidet attachment, one of the biggest concerns is how much electricity does that bidet use? If you live in countries like Australia, you already know the pain of high electricity costs that are constantly rising. This is the case for most parts of the world. Hence, it is normal to worry about its operational cost when you buy an electric bidet. 

Bidets have many benefits. Between electric and non-electric bidets, people prefer electric ones for obvious reasons. Electric bidets offer better features, easy controls, and better comfort. 

Should the bidet electricity usage worry you? Not necessarily. The electricity consumption of a bidet depends on various factors. 

In this article, we shall talk about how much electricity bidets consume. Let’s get started. 

How Many Watts Does a Bidet Consume?

Unless you want to monitor every minute of your electricity consumption after installing a bidet, the easiest way to know a bidet’s electricity consumption rating is to check its manual. On the manual, you will get the maximum power rating in watts. It shows how much power your device would consume when running at full capacity for at least 1 hour. 

In most cases, this is never achieved. However, in the worst scenario, if you really use your device for this extended period, you can easily calculate the total electricity usage per day. But, all these calculations are a job better said than done.

Hence, we went through a lot of those and calculated the average consumption of different types of bidets. First, we will divide bidets into three types:

  • Entry-level Bidets or the cheapest ones
  • Mid-range Bidets
  • Luxury Bidets, or the High-end ones.

Most people would go for entry-level bidets by seeing their wattage consumption while in use. Entry-level bidets consume less wattage when you are using them (around 400W). But, in the long run, they will consume more energy (150 kWh/month). 

Hence, if we are talking about energy-efficient bidet toilet seats, entry-level bidets are not the ones you will want. Mid-range bidets fall somewhere between the entry-level and luxury bidets in the market. 

The maximum power consumption rating for luxury bidets is higher (typically 1200W). But, their overall power consumption is much less (around 9 kWh/month). 

Hence, the overall power consumption of luxury bidets is less. Thus, they are more energy-efficient than the entry-level bidets that you find in the market. 

How Much Electricity Do Bidets Use Per Day? 

As said earlier, when you buy an electrical appliance, you will get to see the max power rating on the manual itself. But, the manual does not tell you how much power it is going to use every day. The maximum power rating is the power consumption of a bidet when it’s working at its full capacity. Hence, in most cases, this is only an idea of the worst-case scenario. 

We went through different tests and came up with the average power consumption of different bidet types based on their base models. For example,

Bidet Type

Max Power Consumption Rating

Entry-Level Bidet

300-400 Watt

Mid-range Bidets

700-900 Watt

High-end or Luxury Bidets

<1200 Watt

Please remember that the power consumption varies according to a lot of factors. For example, if your bidet has a tankless heater, it will consume more power than one with a hybrid heater

Based on our calculations, the findings are thus:

Bidet Type

Power Consumption per Day

Entry-level Bidet

Up to 5400 Watt per day

Mid-range Bidets

Up to 1200-2400 Watt per day

High-end or Luxury Bidets

Up to 466 Watt per day

Please note consumption may vary depending on brands, features, efficiency, frequency of usage, and a lot of other factors. 

One may ask why, despite being so low on max power rating, entry-level bidets end up consuming this much power? 

The entry-level bidets do not consume much power while in use. But, they come with a primitive tank heater that never shuts off. These heaters alone may consume around 225-250 watts of power per hour. Hence, entry-level bidets end up consuming this much overall electricity. 

Bidet Electricity Usage Per Month 

After this, you will always notice the maximum power consumption rating of a bidet before buying it. But, the question is, will it help calculate the actual consumption? No, it will not. Why? Because, as said earlier, the max power rating is only for the worst-case scenario when you use the bidet at full blast. But, it won’t help if your electric bidet toilet seat use is nominal. 

So, you cannot really calculate the monthly consumption based on that. The only way to do this is to measure the kWh or Kilowatt. With this, you can find your electricity bills and see how much power different appliances have used. 

So, we went through several bills to calculate the kWh of different electric bidets. Based on our searches, we were able to get a basic idea of the kWh consumption for all three types of bidets:

Bidet Type

kWh Consumption Per Month

Entry-Level Bidet

162 kWh (including the heater)

Mid-range Bidet

87 kWh 

High-end models

14 kWh

Why Do High-end Models Have Less kWh?

You probably have noticed how high-end or luxury bidets have less kWh measurement despite having a higher power rating. A lot of people might get confused at this point. But this is relatively simple. The max power rating of high-end bidets is high because they come with all sorts of features and specs. 

But, you don’t use most of these features regularly. When you don’t, the standby power consumption is very low. That way, even though the luxury bidets have a high max power rating, the actual consumption is low, leading to the lower kWh reading per month.

How Many Amps Does a Bidet Use?

Ampere or Amp is the SI unit for electric current or “a flow of one coulomb of electricity per second” in an electrical circuit when you are using it. You get the ampere reading of an electrical appliance by dividing volts by watts. 

So, how many amps does a bidet use? 

It again depends on various factors. For example, more additional features lead to higher amp reading. Therefore, the ampere is less for entry-level bidets. An entry-level bidet generally consumes around 4 amp of electricity per second. In the case of luxury bidets, the number can go up a lot. 

Even though the amp unit is higher for luxury bidets, the overall consumption would still be less for them.

On the other hand, entry-level bidets will always consume more electricity than all other types.

How Much do Bidets Cost to Operate?

Now that we know the kWh of each bidet type, it is easy to calculate the cost to operate a bidet. We will calculate the monthly cost to run a bidet based on the latest electricity price in the US, which is 13.75 Cents per Kilowatt-hour for the US households.

For Australia, the electricity price will vary depending on various states. After going through the averages of electricity usage rates of various states, we have calculated an overall average, which is 23.59 cents. 

All we need to do to calculate the cost is multiply the monthly kWh by 13.75 cents for the US and 23.59 cents for the Australian household.

Different Types of Bidets and Their Operating Cost

Now that we know the formula to calculate the operational cost of different bidets, let us start with the entry-level bidets. 

How Much Does It Cost to Run an Entry-Level Bidet?

The monthly bidet electricity usage for entry-level bidets: 162 kWh

Avg. Price of Electricity (USA): 13.75 cents

Avg. Price of Electricity (AUS): 23.59 cents

Average Total Cost (USA): $22.27 per month

Average Total Cost (AUS): $38.21 per month

The cost may vary depending on how frequently you use your bidet. If your bidet use is nominal, it wouldn’t be much.

How Much Does It Cost to Run Luxury Bidets?

The monthly bidet electricity usage for High-end or Luxury bidets: 14 kWh.

Avg. Price of Electricity (USA): 13.75 cents

Avg. Price of Electricity (AUS): 23.59 cents

Average Total Cost (USA): $1.92 per month.

Average Total Cost (AUS): $3.30 per month

Since the kWh rating of luxury bidets is significantly less than the entry-level ones, you get to see such a huge price difference between both these types. Luxury bidets have a lot of features that cause a high max power rating on its manual. But, most of these features do not consume electricity when idle. Therefore, the kWh is significantly low. 

How Much Does It Cost to Run Mid-Range Bidets?

The monthly bidet electricity usage for High-end or Luxury bidets: 87 kWh

Average Price of Electricity (USA(: 13.75 cents

Average Price of Electricity (AUS): 23.59 cents

Average Total Cost (USA): $11.96 per month

Average Total Cost (AUS): $20.5 per month

Mid-range electric bidets have a decent operational cost- neither too high nor too low. Most of these bidets consume an average kWh per month. If you can’t invest in higher-end models, you can always go for mid-range bidets to save electricity and cost.

Do All Bidets Need Electricity?

No. Not all bidets need electricity. Probably the only bidets you came across were those powered by electricity. But they are not the only option. There are plenty of bidets available, each with different features and specs. So, if you don't want an electrical model, you can always pick from non-electric bidets. 

What Is A Non-Electric Bidet?

Non-electric or mechanical bidets are the models that do not require electricity to run. Instead, they are mechanically designed to provide optimum water discharge. The biggest perk of using a standard or mechanical bidet is that they don't need electricity. Hence, you don't have to worry about bills. 

But, non-electric bidets also compromise on some features that you would get in their electrical counterparts. For example, the best bidet toilet seat (non-electric) won't have an in-built heated bidet attachment. Similarly, handheld toilet bidet spray will have limited functions. 

So, there are both pros and cons of using non-electric bidets. They will obviously save you electrical expenses but won't provide as many features as their electrical counterparts. If you are okay with the compromise and choose money over comfort, you can always buy non-electric bidets for your toilet.

Does A Bidet Save Money?

To answer these questions, we need to go through the operational cost once again. The typical cost of operating an electric bidet attachment or electric bidet ranges between $2 to $25. Higher-end bidets cost less while entry-level bidets cost more. Again, there are certain factors that contribute to the cost of operating a bidet.

For example, if an electric bidet has a tankless water heater, it will cost less.  

But do electrical bidet toilet seats save money?

It depends on what you are comparing them with. Many people would compare the expense with buying toilet paper. Can the cost replace the toilet paper expenses? According to Statista, the average price of toilet paper per unit in the USA in 2020 was $7.91. Using an electric bidet can easily replace this cost. BUT only when you use a high-end or luxury model. 

Again, if saving money and the environment is your concern and the reason for shifting to bidet use, we would recommend going for non-electric bidets. These bidets are entirely mechanical. Hence, they do not need electricity to operate. Non-electric bidets, such as this toilet bidet spray, toilet accessories, and bidet attachment are easy to use and do not require power. 

Thus, by using the non-electric models, you don’t have to worry about paying electricity bills. In fact, you will save electricity, the environment, and money! 


This detailed discussion on "how much electricity does a bidet use?" was necessary because there is no generic answer. Electricity consumption varies significantly with the type of bidet you are using. 

Are you buying cheap entry-level bidets to save the initial costs? If you do so, you may end up paying more overall. But, if you invest in luxury models, the investment will soon be recovered thanks to their low overall electricity consumption. That way, you can save money, and the environment and maintain hygiene in the long run.

If you are still confused about what you should buy, then consider the best bidet toilet seat alternative that can assuredly save electricity and money. 

We hope that this article was helpful enough to give you a clear idea of what you should prefer.
