Premier Bidets BBB Business Review

Introducing The All New TOTO S7A

  • The "best bidet seat money can buy": Our best selling TOTO Washlet with the most features
  • Replaces the TOTO S550e: Delivers improved design and upgraded features over the previous flagship.
  • Ultra-slim profile: One of the sleekest bidet seats available (just 4.06" tall in the back)
  • Automatic open/close lid: You'll wonder how you ever lived without it

Instant and Unlimited Warm Water

The TOTO S7A delivers unparalleled comfort with its instant water heater, providing an endless supply of warm water for a luxurious experience.

Featuring four wash settings—front, rear, wide, and soft—allowing you to customize your wash to suit your preferences.

With complete control over water temperature, pressure, and nozzle position, the TOTO S7A ensures a soothing and tailored clean every time.

Automatic Open/Close Lid

The TOTO S7A uses a motion sensor to open the lid as you approach, then closes automatically after about a minute of inactivity.

You can also open and close both the toilet lid and seat separately with the remote control.

Sensitivity and timing can also be adjusted, so it won’t trigger when someone just walks by.

This hands-free feature improves hygiene, reduces germ spread, and makes the bathroom more accessible, especially helpful for those recovering from surgery or with mobility challenges.

Super Sleek Bidet Seat

The TOTO S7A features a sleek design made possible by advanced water heating technology.

Unlike traditional bidet seats that use bulky tank heaters, the TOTO S7A eliminates the need for extra space in the back, creating a slimmer and more modern profile.

Traditional bidet seats with tank heaters can add unnecessary height and cause discomfort by pushing users forward.

The ultra-slim TOTO S7A on the other hand offers a more natural and comfortable sitting experience, making it an ideal choice for everyday use.

Easy to Use Remote Control

The TOTO S7A lets you store up to 4 personalized wash settings on the remote for a true one-touch wash experience—perfect for households with multiple users.

The S7A Washlet also introduces two extra functions to enhance comfort: nozzle oscillation, which broadens spray coverage by moving back and forth, and pulse mode, which alternates water pressure for a gentle massage.

With a compatible auto-flush kit installed (sold separately), you can even flush the toilet directly from the remote.

Advanced Sanitation for Peace of Mind

TOTO has designed the Washlet S7A with an advanced self-cleaning system that elevates everyday hygiene.

Electrolyzed EWATER+ automatically rinses the toilet bowl, bidet nozzles, and the area beneath the seat both before and after each use, delivering a consistently fresh and sanitary experience.

This innovative water technology helps maintain a cleaner toilet bowl over time—reducing the need for frequent scrubbing or chemical cleaners.

The result is a more convenient, eco-conscious approach to bathroom care.

Amazing Toto S7A

The Toto S7A from Premier Bidets arrived quickly and was packed with great care. This was my first bidet and the S7A is nothing short of amazing. Install was easy and took about 20 mins. If you’re already spending this much on a premium bidet, the addition of the open & close functions on the S7A are a nice touch. Premier Bidets also had the best price I could find. Super satisfied overall!

TOTO S7A SW4736AT40 Compatibility Made Easy

When it comes to selecting the right bidet seat for your toilet, understanding the size and shape compatibility is crucial. Toilet bowls come in two primary sizes:

  • round
  • elongated

Round-sized toilets typically measure 16.5" in total length, while elongated toilets are slightly larger at 18.5".

If your toilet has a relatively flat bowl that meets the toilet tank at close to a 90-degree angle, the Washlet S7A should fit seamlessly.

However, if your toilet features a curved tank that meets the bowl on a slope, often referred to as a "french curve" the S7A Washlet unfortunately will not fit.

You will also want to measure the space in between the holes where you attach your toilet seat.

You'll want 5 1/2" of space between them.

Next, make sure there is adequate space between the toilet tank and mounting holes.

For the TOTO S7A, you'll want at least 2"

TOTO S7A Installation Info

When you're in the market for a bidet seat, it's essential to keep a few key factors in mind:

  • ensuring your toilet is compatible
  • having convenient access to a water source
  • GFCI electrical outlet is within 3 feet of the toilet

These considerations will help you make the right choice for your bathroom upgrade

For bidet seats like the TOTO S7A, an electrical outlet within three feet is required. The S7A Washlet can be easily installed at home without a plumber by just following the included installation instructions.
