Flush Type
The TOTO Drake is praised for its uber-efficient tornado flush, taking just about 3 seconds to clear everything.
Installation Requirements
Installation is manageable, even for someone with limited experience, although handling the weight might require some help.
Design and Aesthetics
The CEFIONTECT glaze keeps the bowl pristine, even with frequent use and without constant flushing.

The TOTO Drake Two-Piece Elongated Toilet offers a mix of powerful performance and modern design. Its TORNADO FLUSH system ensures effective cleaning with a circular water motion, combined with the CEFIONTECT glaze to prevent waste buildup, meaning less frequent cleaning for you. The standard height may be more comfortable for those who prefer a traditional toilet height over taller options.

With a 1.6 gallons per flush rate, it conserves water without compromising on the flushing power, thanks to the wide 3-inch flush valve and siphon jet bowl. This makes it efficient, ensuring waste is cleared in one go. The elongated bowl shape adds comfort while the cotton white finish suits various bathroom décors.

It is relatively easy to install, fitting into 12-inch rough-in spaces. However, you will need to purchase the wax ring, flange bolts, and water supply lines separately, which adds to the installation cost. At 89 pounds, it is quite heavy, so handling during installation may require an extra pair of hands. Despite these minor drawbacks, the TOTO Drake stands out for its reliable performance, water efficiency, and sleek design that can enhance any bathroom.

Buying Guide for the Best Rear Drain Toilet

Choosing the right rear-drain toilet involves understanding various specifications that can impact the performance, comfort, and suitability for your bathroom. Rear-drain toilets, also known as rear-outlet or back-outlet toilets, are designed to connect to the plumbing system through the wall rather than the floor. This type of toilet is often used in specific installations where floor plumbing is not feasible. To make an informed decision, consider the following key specifications and how they align with your needs.
Bowl ShapeThe bowl shape of a toilet can be either round or elongated. Round bowls are more compact and are ideal for smaller bathrooms, while elongated bowls offer more comfort due to their larger seating area. If space is limited, a round bowl might be the best choice. However, if comfort is a priority and you have enough space, an elongated bowl would be preferable.
HeightToilet height can vary, with standard height being around 15 inches from the floor to the seat, and comfort height (also known as chair height) being around 17-19 inches. Comfort height toilets are easier to sit down on and stand up from, making them a good choice for older adults or those with mobility issues. Standard height toilets might be more suitable for children or shorter individuals.
Flush TypeFlush types include single-flush, dual-flush, and pressure-assisted flush. Single-flush toilets use the same amount of water for every flush, while dual-flush toilets offer two flush options (a lower volume for liquid waste and a higher volume for solid waste), which can save water. Pressure-assisted flush toilets use pressurized air to force water into the bowl, providing a powerful flush. Consider a dual-flush toilet if water conservation is important to you, or a pressure-assisted flush if you need a more powerful flush.
Water ConsumptionWater consumption is measured in gallons per flush (GPF). Modern toilets typically use 1.6 GPF or less, with high-efficiency toilets using as little as 1.28 GPF. Lower water consumption can lead to significant water savings over time. If you are environmentally conscious or looking to reduce your water bill, opt for a toilet with lower GPF.
Trapway SizeThe trapway is the channel within the toilet that waste travels through. A larger trapway (typically 2-3 inches) can reduce the likelihood of clogs. If you are concerned about frequent clogs, look for a toilet with a larger trapway.
Installation RequirementsRear-drain toilets have specific installation requirements, including the location of the waste pipe and the distance from the wall. Ensure that the toilet you choose matches the existing plumbing setup in your bathroom. If you are unsure, consult with a plumber to verify compatibility.
Noise LevelSome toilets are designed to operate more quietly than others. If noise is a concern, especially in a shared or small living space, look for toilets that are marketed as having quiet flush technology.
Design and AestheticsToilets come in various designs and finishes. While functionality is crucial, you may also want to consider how the toilet fits with your bathroom's overall aesthetic. Choose a design that complements your bathroom decor and meets your personal style preferences.
