What Is TOTO® WASHLET® S5 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Elongated, Sedona Beige – SW3446#12?

The TOTO WASHLET S5 is an elongated electronic bidet toilet seat designed to replace your standard toilet seat. It belongs to the luxury bidet seat category, offering instant warm water cleansing, a heated seat, warm air dryer, and advanced self-cleaning technology. Manufactured by TOTO – a brand synonymous with premium bathroom fixtures – this model is built for those who want a hotel-like experience at home. The S5 is particularly suited for households with multiple users, thanks to its four user memory settings and intuitive wireless remote control. Its standout innovations include PREMIST (a pre-wet function that helps keep the bowl clean) and EWATER+ (electrolyzed water that sanitizes the wand automatically).

At around $780, it competes directly with other high-end bidet seats like the Kohler PureWash E930 and Brondell Swash 1400, but with TOTO’s reputation for durability and water efficiency. If you are serious about upgrading your bathroom, reading a thorough TOTO WASHLET S5 review and rating is essential to confirm it meets your needs.

Key Features & Specifications

Standout Features

• Instantaneous Water Heating: Unlike tank-based models, the S5 heats water on demand, providing an endless warm stream for as long as you need. No more cold shock halfway through.
• PREMIST Technology: Before each use, the seat sprays a fine mist of water onto the toilet bowl surface. This helps waste slide off, reducing the need for harsh cleaning chemicals.
• EWATER+ Wand Cleaning: After every use, the wand is cleaned inside and out with electrolyzed water, which is both safe and powerful. This provides peace of mind, especially for shared bathrooms.
• Heated Seat with SoftClose: The seat offers five temperature settings and closes quietly without slamming. Great for chilly mornings and late-night trips.
• Warm Air Dryer: With five temperature settings, you can air dry comfortably. It is not as powerful as some standalone dryers, but it reduces your reliance on toilet paper.
• Wireless Remote Control: A slim, sleek remote lets you adjust water pressure, spray position, temperature, and even select oscillating or pulsating streams. Four user memory buttons allow personalized presets for each family member.
• Night Light: A subtle, soft glow illuminates the bowl area, making nighttime visits easier without flipping on bright lights.
• Air Deodorizer: Built-in carbon filters neutralize odors before they spread. The fan activates when you sit and continues for a short time after you stand.

What’s Included in the Box

Upon opening the box, you will find the WASHLET seat itself, a wireless remote control (with a mounting bracket and screws), a T-valve connector, a water supply hose, mounting hardware, a quick-start guide, and an instruction manual. The packaging is well-organized, and each component is protected with foam. The seat itself feels solid—no cheap plastic flexing. The remote is lightweight but feels durable. We were pleased to see that TOTO includes everything you need for a standard installation, except for a wrench and a screwdriver. If your toilet has a non-standard water line (e.g., a 3/8-inch compression fitting), you might need an adapter. Overall, the unboxing experience is premium and straightforward, consistent with a TOTO WASHLET S5 review honest opinion expected from a high-end brand.

One note: the Sedona Beige color is a warm off-white that blends nicely with many bathroom decors, but it may not match all toilets perfectly. Check the color of your existing bowl before ordering.

How to Use TOTO® WASHLET® S5 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Elongated, Sedona Beige – SW3446#12: Complete Guide

Step 1: Initial Setup and Installation

Installation is DIY-friendly if you have basic plumbing skills. First, remove your existing toilet seat and turn off the water supply. Unscrew the old seat, then attach the TOTO mounting plate using the supplied hardware. Connect the T-valve to the toilet’s water supply line, then link the WASHLET’s water hose. Plug the unit into a grounded outlet (GFCI is recommended). The entire process took us about 30 minutes. After powering on, the seat runs a self-check cycle. If you encounter any leaks, ensure all rubber washers are seated properly. For a more detailed walkthrough, see our smart toilet installation guide.

Step 2: First-Time User Guide

Once installed, sit on the seat to activate the sensors (the seat detects when you are seated). Use the remote to select a spray type: Rear Cleanse (for general use) or Front Cleanse (for feminine hygiene). Adjust water pressure and temperature to your liking. The remote is intuitive—icons are clear, and buttons have a satisfying click. We recommend starting at a low pressure and gradually increasing until you find the sweet spot.

Step 3: Core Functions and Daily Use

Daily use is simple: sit, press the spray button for a oscillating or pulsating stream, then dry with the warm air dryer. The heated seat can be left on all day (it automatically adjusts to conserve energy). The deodorizer activates when you sit, so odors are minimized. One tip: always let the self-cleaning cycle finish after use—it takes about 15 seconds and ensures hygiene.

Step 4: Advanced Techniques

For advanced users, explore the user memory settings. Program remote button 1 for your preferred pressure and temperature, button 2 for your partner, etc. You can also adjust the nozzle position using the remote arrows. The oscillating mode provides a wider cleaning area, while pulsating can be more massaging. Both are effective, so experiment to find your favorite.

Step 5: Maintenance and Care

Clean the exterior with a soft damp cloth and mild soap—avoid abrasive cleaners. The wand self-cleans with EWATER+, but you should still wipe the nozzle with a damp cloth every few weeks. The deodorizer filter should be replaced every 6-12 months (replacement filters can be found here).

Step 6: Troubleshooting Common Issues

If the seat does not spray when you sit, make sure the sensor is not blocked by thick clothing. If water pressure drops, check the inlet filter for debris. For persistent errors, consult the manual or TOTO’s customer support. In our testing, we experienced no issues, which is a strong point in this TOTO WASHLET S5 review pros cons analysis.

Performance & Real-World Testing

Testing Methodology

We installed the TOTO WASHLET S5 in a master bathroom and used it daily for three consecutive weeks. Two testers of different heights and weights evaluated comfort, cleaning effectiveness, and ease of use. We also measured water temperature consistency, drying efficiency, and noise levels.

Performance Metrics

The instantaneous water heater delivered a steady stream at the set temperature (we tested 95°F and 105°F) without fluctuations. Water pressure range is wide—from a gentle trickle to a powerful jet. The oscillating and pulsating modes provided distinct sensations; both cleaned effectively with minimal water usage. The dryer, while not as strong as a towel, dried in about 90 seconds at the highest setting. Noise levels were moderate—quieter than our older bidet but not silent.

Real-World Scenarios

We tested after heavy meals, during a cold morning, and late at night. The heated seat was a game-changer in winter. The PREMIST function noticeably reduced bowl staining—after two weeks without manual bowl cleaning, the toilet still looked clean. The night light is subtle and helpful.

Claims vs. Reality

TOTO claims endless warm water—true. The EWATER+ self-cleaning works as advertised; the wand looked pristine after weeks of use. The four user memory settings work perfectly. The only gap: the dryer could be more powerful. However, this is a minor trade-off. Overall, the performance reinforces why is TOTO WASHLET S5 worth buying is a common question among consumers—and our answer is yes.

Pros and Cons

What We Loved (Pros)

• Endless Warm Water: The tankless heater provides continuous hot water without the 30-second limit of older models.
• PREMIST and EWATER+: These cleaning innovations reduce maintenance and improve hygiene significantly.
• User Memory Settings: Four presets make it easy for multiple users to have personalized experiences without re-adjusting each time.
• SoftClose Heated Seat: Comfortable, quiet, and five temperature levels ensure comfort.
• Easy Installation: Most DIYers can install it in under an hour with basic tools.

What Could Be Improved (Cons)

• Dryer Could Be Stronger: While effective, the air dryer takes longer than some competing models (e.g., Kohler E930’s dryer is more powerful).
• Plastic Construction: Although high-quality, the seat is entirely plastic. Some users prefer a more substantial feel, though this keeps the weight low.
• Pricey Replacement Filters: The deodorizer filter needs periodic replacement, and the cost adds up over time.

This balanced TOTO WASHLET S5 review pros cons should help you weigh the decision.

Who Should Buy TOTO® WASHLET® S5 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Elongated, Sedona Beige – SW3446#12?

Expert Tips for Maximum Value

Tip #1: Program User Presets for Everyone

Take ten minutes to set up each user’s preferred pressure, temperature, and nozzle position. This small effort saves daily adjustments and ensures personalized comfort.

Tip #2: Use the Premist Feature

Always keep PREMIST enabled. It reduces cleaning frequency and keeps the bowl spotless. It uses minimal water and pays off in less manual scrubbing.

Tip #3: Buy the Right Cleaning Accessories

Use non-abrasive cleaners. We recommend this compatible cleaner to maintain the plastic without damaging it.

Tip #4: Adjust the Dryer Position

Angle the nozzle slightly forward or backward using the remote to direct the warm air exactly where you need it, speeding up drying.

Tip #5: Activate the Night Light for Nighttime Visits

The night light is soft enough to not wake you fully, but bright enough to guide you. Leave it on auto to extend bulb life.

Tip #6: Replace the Deodorizer Filter Annually

Set a calendar reminder to order a new filter every 12 months. A fresh filter maintains optimal odor control.

Tip #7: Use the Oscillating/Pulsating Modes for Discomfort Relief

If you suffer from hemorrhoids or post-surgery sensitivity, the oscillating or pulsating spray can be soothing. Many users find it therapeutic.

Common Mistakes to Avoid

1. Mistake: Forgetting to turn off water before installation → Solution: Always shut off the angle valve to avoid flooding.
2. Mistake: Using harsh chemical cleaners on the seat → Solution: Stick to mild soap and water; bleach or ammonia can yellow the plastic.
3. Mistake: Ignoring the water inlet filter cleaning schedule → Solution: Clean the filter every three months to maintain water flow.
4. Mistake: Assuming the lid is also soft-close → Solution: Close the lid gently; only the seat has the SoftClose mechanism.
5. Mistake: Setting the dryer too high before drying off excess water → Solution: Pat dry with a tissue first, then use the dryer for a quicker finish.
