What Is TOTO® WASHLET® S2 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Round, Cotton White – SW3345#01?

The TOTO WASHLET S2 is a high-end electronic bidet seat that replaces your standard toilet seat, offering a suite of automated cleaning and comfort features. Positioned in the mid-to-upper tier of TOTO’s renowned WASHLET lineup, its primary purpose is to deliver a spa-like, hygienic experience right in your home bathroom. It targets homeowners and renovators seeking to elevate their daily routine with technology that promotes cleanliness, comfort, and sustainability. The key innovations here are its instantaneous water heating system, which provides endless warm water, and its proprietary cleaning technologies: PREMIST for the bowl and EWATER+ for the wand. For decades, TOTO has been a leader in bathroom innovation, and you can learn more about their philosophy and technology on the official TOTO website. When evaluating if the TOTO WASHLET S2 is worth buying, understanding its core purpose as a hygiene and comfort upgrade is essential.

Key Features & Specifications

Standout Features

After extensive testing, several features of the S2 truly set it apart. Here’s what makes it a contender for the best electronic bidet seat in its class:

• Instantaneous Water Heating: Unlike tank-based systems that can run out of hot water, this system heats water on demand, ensuring a continuous, comfortable warm stream for as long as you need.
• PREMIST Technology: This is a game-changer for cleaning. Before you use the toilet, a fine mist of water coats the bowl surface, helping to prevent waste from sticking and making cleanup significantly easier.
• EWATER+ Wand Cleaning: Hygiene is paramount. The wand self-cleans inside and out before and after each use using electrolyzed water, which is a powerful yet safe cleaning agent, giving you peace of mind.
• Fully Adjustable Cleansing: With separate front (feminine) and rear wash settings, plus oscillating and pulsating options, you can customize water pressure and temperature to your exact preference.
• Heated Seat & Warm Air Dryer: The seat offers three temperature settings, while the warm air dryer provides a hands-free drying experience, also with adjustable temperature.
• SoftClose Lid and Seat: No more loud slamming. The lid and seat close gently and quietly every time.
• Energy-Saving Mode: The seat intelligently lowers power consumption when it senses the bathroom is not in use, which is a thoughtful touch for both your wallet and the environment.

Determining if the TOTO WASHLET S2 is worth buying often comes down to how much you value these integrated luxury features. For a deeper look at how it stacks up against other models, see our complete bidet seat buying guide.

What’s Included in the Box

Unboxing the TOTO WASHLET S2 feels like opening a premium appliance. Everything is neatly packed and protected. Here’s the complete inventory you’ll find:

• The main WASHLET S2 seat unit (Cotton White, Round).
• A sturdy mounting plate and hardware kit.
• A water supply hose (T-connector).
• A detailed, illustrated installation manual and user guide.
• All necessary bolts, nuts, and templates for secure installation.

The build quality is immediately apparent. The plastic feels robust and high-grade, not cheap or flimsy. The seat has a substantial weight to it, suggesting durability. It’s worth noting that you will need access to a standard electrical outlet near your toilet for power. If you don’t have one, hiring an electrician is an additional cost to consider. The package includes all the core hardware needed for a typical installation, which is a positive start when asking should I buy TOTO WASHLET S2.

How to Use TOTO® WASHLET® S2 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Round, Cotton White – SW3345#01: Complete Guide

Step 1: Initial Setup and Installation

Installation is straightforward for anyone comfortable with basic DIY. First, turn off the water supply to your toilet and flush to empty the tank and bowl. Remove your old seat. You’ll mount the provided plate to your toilet using the template to ensure proper alignment. Then, connect the water hose from the T-valve (which splits water to both the toilet tank and the WASHLET) and plug the unit into a GFCI outlet. The entire process took us about 30-45 minutes. The manual is very clear, making the question of should I buy TOTO WASHLET S2 less daunting regarding setup.

Step 2: First-Time User Guide

Once powered, the control panel on the side will illuminate. Take a moment to familiarize yourself with the buttons. Key functions are clearly labeled: Stop, Rear Wash, Front Wash, Oscillate, and Dry. We recommend starting with the default settings. Sit down, and you’ll immediately feel the heated seat—a welcome feature, especially in colder months.

Step 3: Core Functions and Daily Use

For daily use, the process is intuitive. After using the toilet, simply press the “Rear” or “Front” button. The wand will extend and begin spraying with warm water. You can adjust the water pressure and wand position using the dedicated buttons. Once clean, press “Stop,” then activate the “Dry” function. The warm air dryer is effective, though drying completely may take a minute or two. This daily routine is where you truly assess if the TOTO WASHLET S2 is worth buying.

Step 4: Advanced Techniques

Explore the oscillating function for a more thorough clean. The “Energy Save” mode can be activated to reduce power when the bathroom is unused for extended periods. You can also adjust the default temperatures for the seat, water, and dryer to your personal preference, which are then saved in memory.

Step 5: Maintenance and Care

Maintenance is minimal. The EWATER+ system handles wand cleaning automatically. For the seat surface, simply wipe with a soft, damp cloth and mild detergent. Never use abrasive cleaners or bleach. Periodically, you may want to clean the inlet filter. For a detailed care routine, see our guide on maintaining bathroom appliances.

Step 6: Troubleshooting Common Issues

If the water isn’t warm, ensure the unit is plugged in and the outlet is working. If the water pressure seems low, check that the water supply valve is fully open and the inlet filter isn’t clogged. The control panel will display error codes for specific issues, which are explained in the manual. For persistent problems, TOTO’s customer support is your best resource. Having a reliable unit is key when forming a TOTO WASHLET S2 honest opinion.

Performance & Real-World Testing

Testing Methodology

We installed the TOTO WASHLET S2 in a primary bathroom and used it exclusively for three weeks. Our testing evaluated comfort, cleaning efficacy, ease of use, energy consumption, and reliability under normal household conditions.

Performance Metrics

The instantaneous water heating performed flawlessly. From the first use, the water was warm within seconds and remained consistently so. The adjustable pressure provided a range from gentle to robust, satisfying different user preferences. The PREMIST function noticeably reduced the need for brushing the bowl. In terms of hygiene, the EWATER+ system provided visible peace of mind, with the wand retracting clean after every cycle.

Real-World Scenarios

For families, the customizable settings are perfect, as each user can find their preferred configuration. For those with mobility issues or conditions like hemorrhoids, the gentle, precise wash is a significant quality-of-life improvement. The nightlight was surprisingly useful for late-night visits, eliminating the need for bright overhead lights.

Claims vs. Reality

TOTO’s claims largely held true. The clean is indeed superior to toilet paper, and the experience is luxurious. The “endless” warm water is accurate due to the tankless system. One minor note is that the warm air dryer, while pleasant, isn’t as instantaneous as toweling off; it requires a short wait for complete dryness. This is a small trade-off for the overall experience. Our performance testing solidly informs our TOTO WASHLET S2 honest opinion.

Pros and Cons

What We Loved (Pros)

• Superior Cleanliness and Hygiene: The combination of targeted washing, warm water, and EWATER+ sanitization offers a level of clean that paper simply cannot match.
• Endless Comfort: The heated seat, instant warm water, and warm air dryer transform a basic necessity into a comfortable, spa-like ritual.
• Innovative PREMIST Technology: This feature genuinely reduces toilet bowl cleaning chores, a major win for any homeowner.
• Customizable User Experience: With adjustable pressure, temperature, and position, it can be tailored to suit anyone in the household.
• Eco-Friendly: Drastically reduces or eliminates toilet paper use, saving money and reducing environmental impact over time.

What Could Be Improved (Cons)

• Premium Price Point: At over $400, it’s a significant investment compared to non-electric bidet attachments or basic seats.
• Requires Electrical Outlet: Installation can be a barrier if an outlet isn’t already nearby, adding potential electrician costs.
• Drying Time: The warm air dryer is effective but not fast; some users may still prefer a pat dry with a small amount of toilet paper for speed.

Weighing these TOTO WASHLET S2 pros cons is crucial for your decision.

Who Should Buy TOTO® WASHLET® S2 Electronic Bidet Toilet Seat with Instantaneous Water Heating, PREMIST and EWATER+ Wand Cleaning, Round, Cotton White – SW3345#01?

Ideal For:

• Homeowners & Renovators: Anyone looking to permanently upgrade their primary bathroom with a luxury fixture that adds comfort and value.
• Individuals Seeking Better Hygiene: Those with health concerns, mobility limitations, or a simple desire for a cleaner, fresher feeling.
• Eco-Conscious Consumers: People aiming to drastically reduce their toilet paper consumption and environmental footprint.
• Families: The customizable settings cater to different preferences, making it a versatile addition for multiple users.

Not Recommended For:

• Renters or Frequent Movers: The installation requirement (electrical outlet) and semi-permanent nature make it less ideal unless you have landlord permission.
• Extremely Budget-Conscious Buyers: If your primary goal is a basic bidet function, a non-electric attachment under $50 will suffice.
• Those Without a Nearby GFCI Outlet: The cost and hassle of adding an outlet may not be justifiable for some.

Expert Tips for Maximum Value

Tip #1: Optimize Your Settings Immediately

Don’t just use the defaults. Spend five minutes adjusting the seat heat, water temperature, and dryer heat to your liking. This personalization is key to getting the full luxury experience and answering for yourself if the TOTO WASHLET S2 is worth buying.

Tip #2: Use PREMIST Every Time

Make it a habit. The PREMIST function is activated by a quick wave of your hand in front of the sensor before you sit. This small step pays huge dividends in keeping your bowl cleaner.

Tip #3: Pair with a Bidet-Friendly Toilet Paper

If you do use a little paper to pat dry, choose a septic-safe, biodegradable brand. This complements the eco-friendly mission of the bidet. Consider a subscription for bamboo toilet paper to maximize sustainability.

Tip #4: Leverage the Energy Save Mode

If you’re going on vacation or have a guest bathroom that’s used infrequently, enable the Energy Save mode from the settings. It significantly reduces standby power consumption.

Tip #5: Perform Annual Filter Maintenance

Once a year, shut off the water, disconnect the hose, and clean the small inlet filter screen. This prevents mineral buildup and ensures consistent water pressure, extending the unit’s life.

Common Mistakes to Avoid

1. Mistake: Not checking for a GFCI outlet before purchase. → Solution: Confirm you have a properly grounded outlet within reach of the power cord. If not, factor in electrician costs.
2. Mistake: Using harsh chemical cleaners on the seat or wand. → Solution: Only use a soft cloth dampened with water and mild soap. The EWATER+ system handles the wand sanitation.
3. Mistake: Overtightening the mounting hardware during installation. → Solution: Hand-tighten firmly, then give a final quarter-turn with a wrench. Overtightening can crack the porcelain of your toilet.
4. Mistake: Expecting the air dryer to be as fast as a towel. → Solution: View the dryer as a comfortable, hands-free finishing touch. For maximum speed, a gentle pat dry with a minute amount of paper is fine.
5. Mistake: Ignoring the user manual. → Solution: The manual contains valuable information on settings, error codes, and care. Skim it during setup to unlock all features.
