One-Piece vs. Two-Piece WASHLET+: Which is the Right Choice for You?
With renovation season quickly approaching, we know one of the most crucial home choices begins with your bathroom. More importantly, which WASHLET+ model—one-piece or two-piece—is the best match for your space?
Though both offer advanced hygiene and convenience, they differ in design, functionality, and user experience. In this guide, we’ll explore the key differences to help you make the best choice for your home.
First, what is a WASHLET+?
For a bit of context, a WASHLET+ is a specially designed TOTO toilet and bidet seat combination that conceals water and electrical connections for a cleaner, more streamlined look. It offers advanced hygiene features such as:
- Front and Rear Cleanse, personalized via remote
- Heated seat with adjustable temperature
- Air deodorizer to maintain freshness
- Auto open/close lid for hands-free operation
- PREMIST® technology to keep the bowl clean longer
- EWATER+ system cleans the wand and bowl after every use
Now, let’s break down the differences between a one-piece and two-piece WASHLET+.
Understanding the Structural Difference: One-Piece vs. Two-Piece
The primary distinction between the two WASHLET+ models lies in their construction:
One-piece WASHLET+:
- Integrated tank and bowl
- Easier to clean and reduces the risk of leaks, as there is no gap between pieces
Two-piece WASHLET+:
- Traditional mode with a separate tank and bowl that are bolted together
- Replacement flexibility, as individual components are easier to replace
Technology Integration: Which Model Offers More?
To start, both one-piece and two-piece WASHLET+ models come equipped with TOTO’s cutting-edge features, such as PREMIST® technology, EWATER+® for automatic nozzle cleaning, a heated seat, and a warm air dryer. However, the integration of these technologies may vary slightly.
One-piece WASHLET+
- Auto-open/close lids
- Touchless TORNADO® flushing
- Tankless flushing system on select models
- Typically have a more streamlined connection to water and power sources
Two-piece WASHLET+:
- Offers a wide range of the same premium features, but some models may require additional installation considerations
- Includes TORNADO FLUSH®, which delivers a powerful water-efficient flush
Which Option Offers the Best Personalized Experience?
One-piece WASHLET+: For those seeking a more luxurious and seamless experience
- Sleek integrated design
- Effortless operation with enhanced cleanliness features
- Modern, low-maintenance solution
Two-piece WASHLET+: For those who prefer a cost-effective and versatile option.
- Easier transport and installation
- Simplified component replacement and repairs
- Ideal for upgrading an existing toilet
Final Verdict: Which One Is Right for You?
If design, ease of maintenance, and integrated look are top priorities, the one-piece WASHLET+ is the best option.
However, if you’re looking for affordability, installation flexibility, and a reliable high-tech upgrade, a two-piece WASHLET+ will still deliver exceptional performance.
No matter which model you choose, both options elevate your bathroom experience with comfort, cleanliness, and state-of-the-art technology—hallmarks of TOTO’s commitment to innovation.
