Key Difference between the S2 Washlet and KS6 Washlet
Controls:
TOTO S2: Features a built-in side control panel that keeps everything attached to the seat. Simple, reliable, and always within reach.
TOTO KS6: Comes with a wireless remote control that includes personalized memory settings for up to 4 users, making it ideal for multi-person households.
John points out, “The biggest difference usually comes down to controls. Multi-user households like the KS6’s remote with memory, while single users prefer the S2’s simplicity.”
TOTO S2: What You’ll Appreciate
- Integrated side controls keep everything attached to the seat. No remote to mount, lose, or manage.
- Pulsating wash can add comfort for users who like alternating pressure.
- Straightforward operation that’s easy for first-time bidet users.
John and team point out, “First-time buyers usually find the S2 less intimidating. The side panel is always visible and feels easy to use.”
TOTO KS6: What You’ll Appreciate
- Wireless remote lets you place controls where they’re easiest to reach.
- Up to 4 user presets so everyone can save preferred temperature, pressure, and spray position.
- Multi-user friendly without re-adjusting settings every visit.
John says to keep this in mind, “Presets are a big win for families who share a toilet — less so for single users, though still convenient in different seasons.”
Why the KS6 Is Better than the S2 – Key Improvements
- Remote Control with 4 User Presets: The remote give you more flexibility and convenience, especially for households with multiple users.
- Same Core Hygiene Tech: The KS6 includes all the cleaning and comfort features of the S2, but adds user customization.
Choose the TOTO S2 if you:
- Prefer integrated, simple controls
- Are trying a bidet for the first time
- Have straightforward bathroom access
Choose the TOTO KS6 if you:
- Want flexible remote control with user presets
- Have multiple users with different preferences
- Prefer not to adjust settings every time you use the seat
Final Thoughts on TOTO S2 vs TOTO KS6
Functionally, these two WASHLET seats are close as both deliver TOTO’s signature hygiene features, instant warm water, and comfort upgrades.
If you value simplicity and a pulsating wash, the TOTO S2 bidet seat is a great fit.
If your household has multiple users or you want remote control with presets, the TOTO KS6 bidet seat is the better match.
John and Team want you to know this, “The choice really comes down to household use. If multiple people share the toilet, the KS6 is worth it. If it’s one or two users, the S2’s simplicity is usually the better fit.”
