Find out how they work and the typical Japanese toilet price with installation to make sure the upgrade fits your budget.
What Is a Smart Toilet?
Instead of a simple porcelain design that flushes manually, a smart toilet is equipped with lots of technology and advanced features to elevate the bathroom experience. Specific features vary by model and brand, but it's common to find smart toilets that have adjustable bidets, dryers, air deodorizers, lights, remotes and self-cleaning technology. Smart toilets are commonly called Japanese toilets because that country is known for its high-tech toilets. Japan is the origin of some popular smart toilet brands, including Toto.
What Is So Special About Japanese Toilets?
Japanese toilets are high-tech, with several integrated features designed for both comfort and functionality. Many of the features help you improve your hygiene and make using the bathroom more convenient. Because there are several setting options, Japanese toilets often allow you to choose preset options so you don't have to adjust the details each time. Common unique details about Japanese toilets include:
Bidet. The toilets generally have integrated bidets with water sprayers that may allow you to adjust the temperature, water pressure, position and stream type.
Dryer. It's also common for the toilet to have a dryer that dries you off after the bidet spray.
Comfortable, convenient seats. Japanese toilets often have features like heated seats and automatic lids to make the bathroom more convenient.
Auto flush. Just like toilets in public restrooms that flush themselves, Japanese toilets often have an auto-flushing feature to reduce contact with potentially dirty surfaces.
Self-cleaning. This dream come true means you'll spend less time cleaning the bathroom, and you'll know the nozzle is immaculate when you use the toilet.
Deodorizers. To make the bathroom more pleasant, some models incorporate air deodorizers.
Sounds. If you prefer a calming environment, find a toilet that integrates nature sounds.
How Much Does a Plumber Charge to Install a Bidet or Bidet Seat?
Stand-alone bidets typically cost more than bidet seats to install. They require a dedicated plumbing line, whereas a bidet seat simply replaces the existing seat. The costs for a stand-alone bidet average $700 to $2,600 (CAD 970 to CAD 3,603) installed, with the unit itself typically costing $250 to $800 (CAD 346 to CAD 1,109), according to pricing data from HomeGuide.
A bidet toilet could cost between $500 and $1,500 (CAD 693 to CAD 2,079) for the toilet itself, with the costs, including installation, ranging from $650 to $2,100 (CAD 901 to CAD 2,910). Meanwhile, a bidet toilet seat could cost $150 to $750 (CAD 208 to CAD 1,039) for just the seat, for a total of $250 to $1,000 (CAD 346 to CAD 1,386) with the installation.
The installation can vary based on what you need to have installed. For example, if your new toilet needs a new plumbing line, you'll likely pay anywhere from $450 to $1,800 (CAD 624 to CAD 2,494) per toilet. If the system requires an electrical outlet, you can expect to pay $150 to $350 (CAD 208 to CAD 485) on top of the plumbing expenses.

How Much Is a Japanese Smart Toilet?
The prices for Japanese smart toilets can vary significantly depending on the brand and the features each model has.
Toto Toilets
You can find Toto toilets with bidets for a little over $1,000 (CAD 1,379), but you can also spend around $25,000 (CAD 34,476) for the top Toto toilets with features like instantaneous water heaters, clean light technology, auto close and aerated dual-action water spray.
Additional Models
Other brands are typically a little lower priced, but you'll also find a range of prices. You can find other brands of smart toilets for under $1,000 (CAD 1,379) along with options between $3,000 and $5,000 (CAD 4,137 and CAD 6,895). To decide, consider your budget and the features that are important to you to find a good balance.
How Much Does It Cost to Install a Japanese Smart Toilet?
The cost to install a Japanese smart toilet is similar to the cost of installing a bidet toilet. You can expect to pay between $150 and $900 (CAD 208 and CAD 1,238) for the installation itself, according to HomeGuide. The main difference is that Japanese smart toilets usually require an electrical outlet to power the smart features. They typically use standard 120V outlets, but they need to be GFCI outlets. Most bathrooms don't have outlets next to their toilets, so you'll likely need to have one installed.
For professional installation, you'll need to hire a plumber, who could charge between $45 and $150 (CAD 62 and CAD 208) per hour for the labor. If you also need an electrician to install a new outlet, you can expect to pay between $50 and $130 (CAD 69 and CAD 180) per hour for the labor. You can expect the process to take between 2 and 4 hours if you're having a stand-alone bidet or bidet toilet installed.
