TOTO Washlet S7 vs. S7A: What’s the Difference?

If you’re shopping for a luxury bidet seat, chances are you’ve come across the TOTO Washlet S7 and S7A. These two models are among the most advanced bidet seats on the market, and the top two models in the TOTO WASHLET lineup—but what exactly sets them apart?

At Bath Butler Bidets, we’re all about helping you make informed, confident choices. So let’s break it down.

🔍 The ONLY Key Difference: Auto Open/Close Lid

The single difference between the TOTO Washlet S7 and the S7A is the Auto Open/Close Lid feature.

Feature	TOTO Washlet S7	TOTO Washlet S7A
Auto Open/Close Lid	❌ Not included	✅ Included

The S7A includes an automatic lid that opens when you approach and closes when you walk away. It’s a small touch that adds a big dose of convenience and hygiene—especially helpful for those with limited mobility or a love for hands-free tech. Customers enjoy this added convenience feature, but the S7A does cost a bit more than the S7 (without Auto Open/Close).

✅ Shared Features:

Premium Comfort in Every Detail

Both the S7 and S7A are packed with TOTO’s most luxurious features:

Instant warm water
Adjustable nozzle and warm air dryer
Heated seat with temperature control
EWATER+ for wand, bowl, and now under-seat cleaning
PREMIST to reduce waste sticking
Massage and oscillating spray modes
Automatic deodorizer
Night light
4-user memory presets
Sleek, seamless seat design
Horizontal remote with tactile buttons
Compatibility with both standard and TOTO T40 toilets (Washlet+ ready)
Compatible and installable on many non-TOTO brand toilets, too! Check the WASHLET Fit Guide to ensure proper fitment onto your existing toilet.

Whether you choose the S7 or S7A, you’re getting a top-tier bidet experience.

Design Options

Both models are available in:

• Cotton White or Sedona Beige

• Classic (beveled edge) or Contemporary (smooth edge) lid styles

• Models available for Elongated or Round shaped bowls

They’re also compatible with TOTO’s Washlet+ system for a seamless, cord-free look.

💡 Which One Should You Choose?

• Choose the WASHLET S7A if you want the full hands-free experience. The auto lid is a game-changer for convenience and cleanliness.

• Choose the WASHLET S7 if you’re okay lifting the lid manually and want to save a bit without sacrificing luxury.

Final Thoughts

Both the TOTO Washlet S7 and S7A deliver an exceptional bathroom upgrade. The choice really comes down to whether the auto open/close lid is worth the extra investment for your lifestyle.
