Final Say So!

The Toto S300e and S500e are both high-end bidet seats, offering a luxurious bathroom experience.

However, they cater to different user needs and preferences.

The S300e is a solid choice for those who value essential features of luxury bidets.

It’s one of the few Toto bidets available for both round and elongated toilets.

However, it’s only available in a Classic design and may be harder to find, potentially making it more expensive.

If you’re someone who prefers a more traditional look and doesn’t mind a potentially higher price for a less common model, the S300e could be a good fit.

On the other hand, the S500e is a more modern option, available in both Contemporary and Classic designs.

It also offers AutoFlush compatibility, which could be a deciding factor for those seeking convenience.

However, it’s only available for elongated toilets.

If you’re someone who appreciates a sleek, modern design and values additional features like AutoFlush, the S500e could be the better choice.

Both models are similar in price, so your decision will likely hinge on your specific needs and aesthetic preferences.

If you’re looking for a round toilet bidet, the S300e is your only option between the two.

If you have an elongated toilet and prefer a modern look, the S500e would be more suitable.

Remember, both models are top-tier Toto bidets, so you’re getting a high-quality product regardless of your choice.
