When it comes to luxury and cleanliness in the bathroom, Toto Washlets set the gold standard. Whether you’re upgrading your own toilet or helping a customer choose the best bidet seat for their home, it helps to understand the differences between the various Toto models.
Toto offers a range of Washlets packed with features like heated seats, instant water heating, customizable wash settings, and even auto-flush on select models. But which one is right for you?
To help simplify your decision, we’ve broken down the features of five current Toto Washlet models—C2, C5, K300, S7, and S7A—along with a brief look at a few discontinued favorites for comparison's sake.
We have put together a full Toto Washlet comparison chart so you can quickly see what each model offers at a glance and be able to know the benefits of each Washlet.
Toto C2 Washlet
A solid entry-level bidet seat. It’s a great starter option—and the best part? You’ll never have to worry about misplacing a remote, thanks to its built-in side control panel. The Toto C2 offers essential features like:
- Immediate warm water from the pre-heated tank, but the warm water supply is finite for each use
- Front and rear wash
- Heated seat
- 3 air dryer and temperature settings
- Premist bowl cleaning
- Side panel controls
Ideal for those who want an affordable, no-frills option that still delivers Toto quality and hygiene.
Toto C5 Washlet
The C5 steps up from the C2 with a few key upgrades:
- Remote control instead of a side panel
- User presets (up to 2)
- A more refined design and interface
If you're looking for more convenience and a sleeker look, the C5 is worth the upgrade. We love recommending this model to people who are looking for a bidet seat.
Toto K300 Washlet
The K300 strikes a perfect balance between the entry-level C2 and the high-end S7A. It offers a noticeable step up in performance and comfort without reaching the premium price point of the S7 or S7A. Take things to the next level with:
- Instant water heating
- A slimmer design (On-Demand Heating: Instead of storing a reservoir of heated water (like older bidet models or traditional water heaters), the K300 heats the water as it flows through the unit.)
- Ewater+ wand sanitation
- 2 user presets
- 3 settings for air dryer, seat, and water temp
Great for smaller bathrooms or minimalist setups where space-saving matters. Not to mention this is the first entry in the line up with Toto’s eWater+
Toto's EWater+ is a game-changer for bathroom hygiene. It works by electrolyzing water, producing a potent, yet harmless solution of hypochlorous acid and sodium hydroxide. This allows your Washlet to automatically mist the toilet bowl and cleanse the bidet wand, proactively suppressing bacteria and waste without a drop of harsh chemicals. It's effortless, automatic cleanliness that delivers true peace of mind, completely free of added chemicals, and safe for people and the environment.
Toto S7 Washlet
The S7 is part of Toto’s latest generation and brings luxury into everyday use. Key features include:
- Instant water heating
- Full Ewater+ coverage (wand, bowl, under seat)
- 4 user presets
- 5 settings for everything: air, seat, and water temp
- Remote control
- Night light for added visibility
It’s a high-performance option for those who want comfort and control.
Toto S7A Washlet
Lastly, our top pick among all the Washlets is the Toto S7A. This is the flag ship model from Toto, the best of the best, this is the ultimate choice. It offers everything you love about the S7, plus advanced automation features for a truly hands-free experience. Additional features include:
- Auto open/close lid
- Auto-flush option (when paired with compatible toilets)
- All other S7 features included
This is the top-tier Toto Washlet for a truly hands-free bathroom experience.
What About the Discontinued Models?
You may have seen the Toto S550E, S500E, S350E, and S300E in past product listings or reviews. While these models have been discontinued, they were highly rated and packed with features.
If you’re looking for a current Toto Washlet that matches what those models offered, the S7 and S7A are your best bet. They are the natural successors in terms of function and style—and in some cases, even better.
Which Toto Washlet Should You Choose?
If you’re focused on budget: Start with the C2 or C5.
Looking for a slim, tankless option: Check out the K300.
Want top-of-the-line features: Go with the S7 or S7A.
No matter your budget or priorities, Toto Washlets bring cleanliness, comfort, and high-tech convenience to your daily routine.
