Main Differences Between the Models
In the course of the comparison, we’ll see a few differences between the models. Whatever seat you’ll choose, you’ll get approximately the same functions. But here are the crucial moments to mind:
- The 500 series products were designed especially for elongated toilets. And the 300 series fits round bowls only.
- TOTO S550E and S350E offer useful nightlight function unavailable in two other seats.
- Like the lighting, automatic lid opening and closing is supported only in the 550 and the 350 bidets.
- All models use remote controls and provide the same buttons and customization options. However, we see different remote control designs.

Sophy
Hello! Are electric bidet seats resistable to all detergents? And is it safe to wash them with water?
Marcus Robertson
Hi, Sophy! Thank you very much for your question! Yes, TOTO seats are waterproof, which means you can wash them. However, we do not recommend immersing your seat in water completely. As for detergents, all types of safe and gentle solutions are allowed.
Lana
Thank you for the comparison! Do bidet sticks hygienic if several people use the seat? May they touch body or can we adjust its position anyhow?
Marcus Robertson
Hi, Lana! Thank you very much for your kind words and question! TOTO bidet seats are completely hygienic. Seats and sticks are adjustable so you can install them in the most convenient position for you and your family members. Family use is allowed.
Anastasia
Do seats require definite toilet dimensions? Will they be suitable for any toilet size?
Marcus Robertson
Hi, Anastasia! Thank you very much for your question! Each of four models discussed in this review has its dimensions (check in comparison table). That’s why we’d recommend choosing an electronic bidet seat that strictly meets your toilet dimensions.
