Performance: 5/5 
The S7A's performance is absolutely perfect and built for maximum ease. The instantaneous heating means you get an endless, powerful stream of warm water—you'll never run out, guaranteed. The EWATER+ system is ramped up to sanitize both the wand and the entire toilet bowl proactively, drastically cutting down on how often you have to clean manually. The warm air dryer is seriously effective, too. Plus, the subtle in-bowl night light and the enhanced, seamless-look seat profile are just fantastic little touches that make a huge difference.
User Experience: 5/5
The user experience is straight-up amazing, defined by effortless luxury. The Auto Open/Close Lid (it just senses when you walk up!) and the Auto Flush compatibility (requires a separate kit) make this setup almost entirely hands-off, which is the single best reason for upgrading to this model. If you have an older Toto toilet, you will want to check compatibility with your toilet model. The S7A features the absolute slimmest seat design TOTO has ever made, giving it a sleek, integrated look. Control is handled via a gorgeous, wall-mounted remote, which keeps the practical four user memory settings introduced in the S5, allowing complete customization for the whole family.
Quality: 5/5
As TOTO's flagship product, the S7A shows off TOTO's best engineering and material quality. The construction is incredibly durable, and the ultra-slim design is achieved without giving up stability or functionality. The seat features TOTO's specialized CLEAN RESIN coating to actively fight dirt buildup. Every component is designed for long-term reliability and market-leading aesthetics, confirming its perfect score in quality.
Value: 5/5
Yes, the S7A is the most expensive bidet seat TOTO offers, but its value is genuinely unmatched. The combination of features—the unique Auto Open/Close Lid, Auto Flush capability, and the full EWATER+ system—aren't found together in a single lower-tier model. For the user seeking the complete, future-proof, touchless experience and the slimmest design on the market, the premium price is totally worth it, making it a brilliant long-term investment in superior hygiene and convenience.
Final Verdict
Honestly, the TOTO S7A Washlet isn't just a gadget—it's the ultimate bathroom glow-up. It takes the solid foundation of the S5—tankless heating, EWATER+, and user presets—and adds the crucial Auto Open/Close Lid and Auto Flush compatibility. These features cement the S7A's status as the top-tier, undisputed market leader. If you want the absolute pinnacle of cleanliness, comfort, and hands-free convenience, the S7A is unequivocally the best luxury bidet seat available and fully deserves its perfect rating.
