Top 5 Best Toto One Piece Toilets With Washlet (2025 Review)

The Toto Washlet & Integrated Toilet

Picture this: you wake up in the middle of the night, half asleep. You stumble your way into the bathroom, and suddenly a soft light turns on at your toilet guiding your path. And before you get to the toilet, the lid automatically opens.

Without lifting a finger, you sit down on the bidet toilet, and it isn't an icy tundra. The toilet seat is actually warm, giving you a pleasant sensation. And after you do the deed, the washlet kicks into action, gently cleaning you and then drying your bottom with warm air. On top of that, an air deodorizer cleanses the air so there aren't any harsh odors.

How To Pick The Best Toto Washlet And Integrated One-Piece Toilet?

Let's face it: Toto washlets and integrated toilets can have a ton of features, and it can be difficult to choose the best one. Below are few tips on how to choose the best Toto toilet...

#1. Cleanliness

Probably the biggest gripe homeowners have about Toto toilets is that some of them just don't stay clean.

After all, one of the biggest reasons to by a Toto washlet & toilet is that it's a more hygienic way to clean yourself — it's expected that the toilet doesn't easily get dirty.

Even though all Toto toilets have a cefiontect glaze to help prevent staining, as well as pre-misting technology — people still report staining and constant cleaning. And after you spend serious dough on a Toto toilet, the last thing you want to have to do is get on your knees and clean a toilet. If this is a concern, I would look into a Toto toilet that doesn't have a bad reputation for cleanliness.

#2. Self-Closing Lid

Toto toilets feature self-closing and self-opening toilet lids.

What this means is that as you approach the bidet toilet, a sensor detects you there and automatically opens the lid. And no more nagging your significant other to close the lid, it will self-close and defuse that argument once and for all (a topic of national debate).

However, some people actually find this feature annoying because if your toilet is near a sink or some other object, you may be constantly causing the lid to open and close even when you aren't using the toilet. 

And the same thing can apply to the toilet light. If the light keeps turning on even when you aren't using the toilet, it bugs some homeowners.

#3. Heated Seats

Most if not all of the Toto washlets have heated toilet seats. This means it uses a heating element to keep the toilet seat nice and toasty, and adjust it to your preferred temperature.

You can set it to come on automatically, or you can choose the seat heater manually.

Imagine this: you enter the bathroom on a cold winter morning, and as you sit down, a warm toilet seat welcomes you rather than an icy slab of ice.

#4. Poor Flushing

And the majority of these Toto washlet toilets are dual flush type toilets. That means that there is a special flush valve that will deliver a precise amount of water to the toilet — rather than the simple flapper that most toilets have. So basically you have the choice to flush at a larger or smaller volume, a flush for solid waste or liquids.

Dual flush toilets can save gallons of water per user every single day — potentially saving you a lot of water over a year. So in short, dual flush toilets are much more efficient than standard toilets.

However, even though I love dual flush toilets, some people find they just don't flush as well as standard toilets. All of my top picks for Toto bidet toilets are dual flush except one.

#5. Washlet Sprayer Adjustability

With Toto washlets, there is usually a front and rear washer.

All of them have adjustable pressure and temperature settings. With some Totos, you will be able to store in memory your preferences, usually up to two users. Some Toto washlet sprayer wands are also self-cleaning which can save a lot of hassle.

#6. Tornado Flushing Technology

Pretty much all of my Toto top picks include tornado flushing technology. 

Tornado flushing is unique because instead of flushing with many tiny holes along the rim (like most toilets), Toto toilets with this technology use two powerful jets of water.

These two jets create a powerful cyclonic flush that helps keep your toilet bowl and rim clean. It is also more efficient than standard toilets — usually using around 1.28-gallons of water per flush.

What Is A Toto Washlet With A One Piece Toilet?

A Toto washlet with a one piece toilet is a bidet system that is integrated into a one piece toilet. A one piece toilet is where the towel bowl and toilet tank are one piece rather than two separate parts like a standard toilet.

The nice thing about Toto bidet toilets is that it is made a single product, so it just works better. Plus, there isn't an ugly water line going to the bidet like you would have with a washlet attachment that isn't integrated.

Toto is a japanese global toilet manufacturer that began to manufacture toilets in the USA two decades ago.
