TOTO is a well-known brand that specializes in manufacturing toilets and bathroom fixtures. They are known for their innovative designs, advanced technologies, and high-quality products. When comparing different TOTO toilets, you might come across various models with differing features. Here are some common differences you might find:

1. Flush Mechanisms: TOTO offers a range of flush mechanisms, including gravity-based flushes, pressure-assisted flushes, and dual-flush systems. Gravity-based flushes are common and use the force of water dropping from the tank to create a siphoning effect. Pressure-assisted flushes use air pressure to enhance flushing power, and dual-flush systems allow you to choose between a light flush for liquid waste and a stronger flush for solid waste.
2. Water Efficiency: TOTO is known for its commitment to water conservation. Different models might have varying levels of water efficiency, often measured in gallons per flush (GPF). TOTO has toilets with ultra-low water consumption, such as 1.28 GPF or even lower for some models.
3. Bowl Shape and Size: TOTO offers various bowl shapes, including elongated and round-front bowls. Elongated bowls are more comfortable for many people but might require slightly more space. Round-front bowls are more compact and are suitable for smaller bathrooms.
4. Seat Features: Some TOTO toilets come with integrated bidet seats or washlet features. These seats offer cleansing with water, heated seats, adjustable water pressure, and various other customizable settings for enhanced hygiene and comfort.
5. Design and Aesthetics: TOTO toilets are available in a wide range of designs, from traditional to modern. You can choose a style that complements your bathroom's aesthetic.
6. Rough-In Size: The rough-in size refers to the distance between the wall and the center of the toilet drain. TOTO toilets are available in different rough-in sizes to accommodate various bathroom layouts.
7. Flushing Technologies: TOTO is known for its advanced flushing technologies that ensure efficient waste removal while minimizing clogs. Some models might have features like a wider trapway, glazed bowl surfaces, and powerful flush jets.
8. Installation Type: TOTO toilets come in various installation types, including floor-mounted and wall-mounted options. Wall-mounted toilets are hung from the wall and offer a sleek, modern look.
9. Price Range: TOTO toilets come in a range of price points. Higher-end models might offer more advanced features and designs, while more budget-friendly options provide basic functionality without compromising on quality.

When choosing a TOTO toilet, consider your preferences, bathroom space, budget, and any specific features you desire. Reading product specifications, customer reviews, and seeking advice from professionals can help you make an informed decision based on your needs.
