Smart toilets are packed with high-tech features—heated seats, bidet functions, automatic lids, deodorizers, and more. While these features bring luxury and convenience, many homeowners wonder: do smart toilets use more electricity than traditional toilets? And if so, how much?
Let’s break down the facts, typical energy consumption, and what it means for your utility bills.
How Much Power Does a Smart Toilet Use?
Unlike standard gravity-flush toilets, do smart toilets need electricity to operate their electronic features. Yes, toilets do use electricity when they come with advanced features, and most of them cannot function fully without a nearby outlet.
| Feature | Average Power Consumption |
|---|---|
| Heated Seat | 50–60 watts (when active) |
| Warm Water Bidet | 300–400 watts (during use) |
| Automatic Flushing | Minimal (few watts) |
| Night Light/LED | <1 watt continuous |
| Air Dryer | 200–300 watts (per use) |
| Standby Mode | 1–2 watts |
Most smart toilets remain in standby mode until activated. Features like heated seats and warm water may use energy continuously if left on all day. This makes them different from traditional toilets, which are not electric at all.
Estimated Yearly Energy Cost
Energy cost varies by usage and electricity rates. Here’s a rough estimate for an average household:
| Usage Scenario | Annual Electricity Cost (USD) |
|---|---|
| Heated seat always on | $20–$40 |
| Heated seat with timer | $10–$20 |
| Bidet & dryer (5 uses/day) | $15–$30 |
| Total (moderate use) | $30–$50 |
Tip: Using built-in timers or eco modes can cut energy consumption by up to 50%. If you’re wondering how much power does a bidet use, it’s typically in the 300–400 watt range during operation.
Do Smart Toilets Increase Electricity Bills Significantly?
In most homes, a smart toilet’s power use is similar to running a few low-wattage appliances. Compared to items like dryers or ovens, the energy draw is relatively small. If you want a low-power consumption toilet, you can look for models with eco features or timers.
Factors affecting power consumption:
- Frequency of bidet/dryer use
- Whether the seat heater runs 24/7 or on a schedule
- If eco/power-saving modes are enabled
If left running continuously, energy costs increase—but with smart settings, the increase is minimal. This is why an energy-efficient smart toilet is recommended for long-term savings.
Built-In Energy-Saving Features
Many modern smart toilets come with features that help reduce power usage:
- Programmable seat heaters (on only during expected times)
- Motion sensors to trigger heating when occupied
- Instant water heaters that activate only during bidet use
- Auto shut-off for lights and deodorizers
These features ensure the toilet isn’t constantly drawing high power, making it more like a low-power consumption toilet instead of an energy-hungry device.
Smart Toilet vs Traditional Toilet: Electricity Comparison
| Feature | Traditional Toilet | Smart Toilet |
|---|---|---|
| Electricity Use | None | Low (varies by features) |
| Water Use | Higher (unless dual flush) | Lower (efficiency-focused) |
| Installation | Simple | Requires power outlet near toilet |
A smart toilet adds a small electrical cost but may reduce water bills with efficient flushing and cleaning. Still, people often ask: are toilets electric or completely mechanical? Traditional ones are not, but do smart toilets require electricity to function – yes, they do.
Ways to Reduce Energy Use
If you’re worried about power consumption:
- Use eco mode for all functions
- Turn off heated seat when not needed
- Set a timer so features don’t run overnight
- Disable dryer function if you prefer towel drying
These steps can cut electricity use by up to 30–50% depending on model. For those asking, “does a toilet use electricity at all?” – only smart models do, and the consumption is fairly small compared to other appliances.
Should You Worry About Energy Use?
For most households, smart toilets add $30–$50 per year to electricity bills under moderate use. This is lower than many assume and can be offset by lower water usage and better hygiene features.
But an important question many ask is: how do you flush a smart toilet without power? Most models include a manual override or backup flush system, ensuring you can still use it during power outages.
Consider electricity cost as part of the overall luxury and convenience—similar to adding heated towel racks or underfloor heating. An energy-efficient smart toilet balances comfort with controlled power usage.
Yes, smart toilets use more electricity than standard toilets, but the increase is relatively small in the context of a household energy budget. By using built-in energy-saving features and managing settings smartly, power costs can be kept low.
If you’re drawn to the comfort, hygiene, and tech benefits of a smart toilet, electricity use shouldn’t be a major deterrent—just plan for an extra few dollars a month and install a power outlet nearby during renovation. So, hopefully this answers your question, does smart toilet need electricity? Yes, but the consumption is low and manageable.
