🛠️ Design and Aesthetics: Sleek and Modern
The G450 stands out for its seamless one-piece construction, which gives it a sleek, contemporary look. It’s easy to clean, visually appealing, and ideal for modern bathrooms. The elongated bowl and chair height boost comfort, while the classic “Cotton” white finish blends well with any decor. Plus, the integrated Washlet seat avoids the bulkiness of add-on bidet attachments, maintaining clean design lines.
🚿 Bidet Functionality: Full-Featured Hygiene
The Washlet G450 seat is packed with advanced features that elevate your bathroom experience:
-
Warm Water Spray – Adjustable temperature and pressure
-
Air Dryer – Reduces toilet paper use and enhances hygiene
-
Heated Seat – Customizable warmth, perfect for winter mornings
-
Automatic Deodorizer – Keeps the air fresh
-
EWATER+ Cleaning – Uses electrolyzed water to clean the bowl and wand after every use
-
Auto Open/Close Lid – Adds hands-free convenience
-
Nightlight – Subtle illumination for nighttime use
🧠 Note: The remote offers many settings, so it may take a little time to master.
💧 Flushing Performance: Water-Saving Yet Powerful
With a dual-flush system (0.8 and 1.0 GPF), the G450 is both eco-friendly and efficient. Its Tornado Flush mechanism uses centrifugal force to clean thoroughly while conserving water. It handles everyday use well, though—like many low-flow toilets—a second flush may occasionally be needed for larger loads.
🪑 Comfort and Ergonomics: Designed for All-Age Comfort
The chair-height design mimics the feel of standard seating, which makes it easier to sit and stand—especially for seniors. The elongated shape adds extra comfort, and the heated seat is a game-changer on cold mornings.
🧰 Installation and Maintenance: Advanced, But Manageable
This model requires both water and electrical hookups, so installation may be more involved than a standard toilet. For most buyers, hiring a plumber and possibly an electrician is a smart choice. Fortunately, once installed, upkeep is easy thanks to features like:
-
CEFIONTECT glaze – Resists stains
-
EWATER+ – Keeps surfaces cleaner longer
💲 Price and Value: Premium, With Benefits
The G450 sits in the high-end category, but you’re paying for premium build quality, hygiene features, and long-term water savings. It’s not for every budget, but it’s ideal for those upgrading a master bathroom or prioritizing comfort and cleanliness.

🛍️ Buying Guide: What to Know Before Buying a High-Tech Toilet
Investing in a smart toilet isn’t just about comfort—it’s also about getting the right features for your space, lifestyle, and budget. Before hitting that “Buy Now” button, here are some things to consider:
🚽 1. Toilet Type: One-Piece vs. Two-Piece
The TOTO G450 is a one-piece toilet, which means the tank and bowl are fused together.
Why it matters:
-
Easier to clean (no gaps for grime)
-
Sleeker look
-
Usually more compact—great for smaller bathrooms
If you’re tight on space or love minimalist design, this is a big plus.
💧 2. Flush System: Single vs. Dual Flush
Dual flush toilets give you two options—light flush for liquids (0.8 GPF) and full flush for solids (1.0 GPF).
Why it matters:
-
Saves water, which lowers your utility bill
-
More eco-friendly
-
Helps meet green building standards
Look for WaterSense or other certifications if you’re aiming for an energy-efficient home.
🧻 3. Bidet Features: What’s Included?
Bidet functionality is what sets luxury toilets apart. The TOTO G450 includes:
-
Front and rear warm water spray
-
Air dryer
-
Heated seat
-
Deodorizer
-
Auto open/close lid and auto flush
Tip: Make sure your bathroom has a nearby power outlet, since these features need electricity.
📏 4. Bowl Shape & Seat Height
This model is elongated and chair-height, which means:
-
More comfortable to sit on (especially for adults or seniors)
-
ADA-compliant—great if you’re thinking about aging-in-place or universal design
Standard toilets sit at 15″–16″ high, while chair height is around 17″–19″.
🔌 5. Installation Requirements
-
Electrical outlet: This is a must for the bidet and auto functions
-
Waterline connection: Standard, but should be checked during installation
-
Wall clearance & layout: Make sure your bathroom layout supports the size of the unit
If you’re not handy, hiring a professional plumber is a good idea—especially for electrical hookup.
🧽 6. Maintenance & Cleaning
Look for features like:
-
CEFIONTECT glaze: Prevents dirt from sticking
-
Auto cleaning nozzles: Keeps the bidet fresh
-
Self-deodorizing function: Neutralizes odor after use
These reduce the need for harsh cleaners and scrubbing, which keeps your toilet in great shape for years.
💸 7. Budget & Warranty
The TOTO G450 is a premium option, but its features justify the cost if you’re upgrading a master bathroom or want extra comfort.
Look for:
-
Brand reputation (TOTO is known for reliability)
-
Warranty coverage (usually 1–3 years for parts)
Tip: Consider it a long-term investment in comfort, hygiene, and water savings.
📝 Final Buying Tip
If you:
-
Care about hygiene
-
Want to upgrade your bathroom experience
-
Prefer a modern, low-maintenance toilet
-
And don’t mind spending a bit more upfront…
👉 The TOTO Washlet G450 is a solid choice.
But if you’re on a tighter budget or just want basic bidet features, consider a bidet seat add-on first—then upgrade later.
- ✅ Covered under TOTO's 3 year limited warranty and 1 year commercial warranty
- ✅ Coordinates with products from the Washlet line seamlessly
- ✅ Two-piece configuration allows for easier access to the area around the toilet
