TOTO® Drake Tank 1.6 & 0.8 GPF Dual Flush Cotton Washlet + ST746SMA01 →

Introduction

Homeowners looking to reduce water consumption without giving up everyday bathroom comfort often have to balance flushing performance, efficiency, hygiene, and available space. The TOTO® Drake Tank 1.6 & 0.8 GPF Dual Flush Cotton Washlet + ST746SMA01 brings these priorities together in one integrated bathroom solution, combining dual-flush functionality with Washlet bidet features. This review takes a closer look at its design, water-efficiency features, installation considerations, and everyday practicality to help you decide whether it suits your bathroom and household needs.

Product Overview

The TOTO Drake is designed for contemporary residential bathrooms where water efficiency and personal hygiene are important considerations. Its dual-flush configuration provides two water-volume options, allowing users to select a lower-volume flush for lighter waste and a higher-volume flush when more flushing power is appropriate. The integrated Washlet functionality adds bidet-style cleansing without requiring a separate bidet fixture, helping create a cleaner and more streamlined bathroom setup.

For homeowners planning a bathroom renovation or replacing an existing toilet, the combination of flushing technology and Washlet functionality can provide a practical way to incorporate multiple features into a single installation. As with any integrated toilet and bidet system, however, available space, electrical access, plumbing configuration, and installation requirements should be reviewed before purchase.

Key Features Explained

Dual Flush Technology

The 1.6 GPF full flush and 0.8 GPF reduced flush give users greater control over water usage. The lower-volume option is intended for lighter waste, while the full flush provides additional water when a more thorough flush is appropriate. Over time, having two flush options can help households use water more efficiently than relying on a single high-volume flush for every use.

Integrated Washlet Functionality

The Washlet design brings bidet-style personal cleansing directly into the toilet setup. Instead of adding a separate bidet fixture, homeowners can incorporate cleansing functionality into the toilet area itself. This can be particularly useful in bathrooms where floor space is limited or where a streamlined appearance is preferred.

Space-Conscious Bathroom Design

Combining toilet and bidet functionality into one system can simplify the overall bathroom layout. For smaller bathrooms, guest bathrooms, or renovation projects where adding another fixture is impractical, an integrated Washlet configuration can provide additional functionality without requiring a separate bidet footprint.

Pros and Considerations

What we like:

• Flexible water usage: The dual-flush configuration gives users the option to select a lower or higher water volume depending on the type of waste.
• Integrated bidet functionality: The Washlet system adds personal cleansing capability without requiring a separate bidet fixture.
• Streamlined bathroom layout: Combining multiple functions in one toilet setup can be useful when floor space is limited.
• Classic Cotton finish: The neutral color can coordinate easily with many traditional and contemporary bathroom designs.
• TOTO engineering: TOTO's extensive experience in bathroom fixtures makes the Drake platform a familiar option for homeowners and plumbing professionals.

Things to consider:

• Installation requirements: An integrated Washlet setup can involve both plumbing and electrical considerations, so the bathroom should be checked for compatibility before installation.
• Electrical access: Depending on the specific Washlet configuration, an appropriate electrical connection may be required near the toilet.
• Component compatibility: Buyers should confirm that the tank, bowl, seat, and associated components are the correct compatible models before ordering or installing.
• Maintenance and servicing: Integrated systems contain more components than a basic toilet, so replacement parts and service requirements should be considered over the product's lifespan.

Frequently Asked Questions

Q: Is professional installation necessary for this model?

A: Installation requirements depend on the existing bathroom configuration and the specific components included with the system. Because the installation can involve toilet plumbing as well as Washlet-related electrical and water connections, professional installation is a practical choice for homeowners who are not experienced with bathroom plumbing or electrical work.

Q: When should the 0.8 GPF flush be used?

A: The reduced-volume flush is intended for lighter waste and can help minimize unnecessary water usage. The higher-volume 1.6 GPF flush provides additional water when a stronger flush is appropriate. Following the manufacturer's operating and installation instructions is recommended for the best performance.

Q: Does the Washlet require an electrical connection?

A: Washlet functionality typically requires electrical power. Before installation, verify the electrical requirements for the specific ST746SMA01 configuration and make sure the bathroom has a properly installed, code-compliant outlet in the appropriate location.

Q: How does an integrated Washlet compare with a separate bidet?

A: An integrated Washlet can provide bidet-style cleansing while keeping the toilet area more compact than a separate toilet-and-bidet arrangement. A separate bidet, however, offers independent fixtures and may provide greater flexibility for homeowners who prefer traditional bathroom layouts.

Q: Is the TOTO Drake suitable for a bathroom renovation?

A: It can be a practical option for renovation projects where the existing plumbing layout and available space are compatible. Before purchasing, confirm rough-in dimensions, bowl and tank compatibility, electrical requirements, and all manufacturer specifications for the intended installation.

Final Verdict

The TOTO® Drake Tank 1.6 & 0.8 GPF Dual Flush Cotton Washlet + ST746SMA01 combines water-conscious flushing with integrated bidet functionality in a streamlined bathroom configuration. Its two flush-volume options can help households manage water use, while the Washlet functionality adds a personal-cleansing feature without requiring a separate bidet fixture. The combination makes this type of system particularly relevant for homeowners planning bathroom upgrades, space-conscious installations, or a move toward more integrated bathroom technology.

Best for: Homeowners interested in dual-flush water efficiency, integrated Washlet functionality, streamlined bathroom layouts, and a classic Cotton finish. Before purchasing, verify the complete product specifications, compatible components, rough-in requirements, and electrical needs for your particular bathroom.
