With TOTO's latest release of three new bidet seats (S2, S5 KS6), we have created an updated comparison table for the complete TOTO lineup in 2025. With these new seats also comes the demise of the C2, C5, and K300 seats. What's the difference? Mainly, there are no longer any TOTO Washlets that utilize a reservoir for heating water.
