## Cons

- Programming the controls requires carefully reading the manual, which some users may find a bit tedious

- The included plastic “T” fitting for water hookup is considered inferior and often replaced with metal by users

## Bottom Line

The TOTO SW4736AT40#01 WASHLET+ Electronic Bidet Toilet Seat is a high-end, feature-rich bidet seat that delivers excellent comfort, cleanliness, and convenience with thoughtful touches like auto lid operation and effective e-water pre-misting. While the remote controller's feel and the plastic water fitting could be improved, these are minor quibbles given its overall performance and reliability. This product is well worth the investment if you want a sleek, easy-to-use bidet that fits perfectly on TOTO toilets and offers superior hygiene and comfort. Make sure to set aside some time to understand its programming and consider professional help for installation if you’re remodeling your bathroom. If you want a similarly reliable and feature-packed experience with a matching TOTO toilet setup, this model is tailored for that.
