The toilet is a centerpiece of a functional and comfortable bathroom. Beyond aesthetics, several practical factors—including dimensions, height, and flushing mechanism—need to be weighed to pick a toilet that suits your bathroom layout, budget, and daily needs.
Not all toilets are created equal. Here are the key considerations for selecting your ideal toilet:
When a siphonic toilet flushes, the trapway fills with water to trigger a siphoning effect that pulls waste downward. At the same time, water rushing from the tank through the rim and jet pushes waste out of the bowl. This combined push-pull action ensures a thorough, full evacuation of the bowl with every flush.
A wash-down toilet relies solely on the force of water pouring from the tank to push waste down the outlet. Unlike siphonic models, it does not fully empty the bowl. These toilets typically feature a small water surface area (4″ x 5″) positioned deep within the bowl.
Regional Trends: Most toilets in the US and Greater China are siphonic, while European and many Asia Pacific markets favor wash-down designs.
For high-traffic bathrooms or households prone to clogs, a high-performance flushing system is essential. Look for toilets with:
- Large flush valves (over 2 inches in diameter): Deliver water at greater speed and pressure.
- Wide trapway outlets (over 2 inches in diameter): Move bulky waste efficiently without clogging.
This system balances maximum flushing power with minimal water consumption. The bowl’s engineered shape propels water forward to create a strong swirling momentum, ensuring thorough waste removal. As a rimless design, it cleans the entire bowl interior evenly, preventing dirt and limescale buildup—and making cleaning a breeze. It is particularly ideal for busy or large families looking to save water without compromising performance.
Note: Water savings are calculated by comparing the Double Vortex system against conventional single-flush toilets.
A one-piece toilet integrates the tank and bowl into a single, seamless unit (formed from 6–10 individual components during manufacturing). Its sleek, gap-free design eliminates crevices where dirt and odors can accumulate, and it offers a streamlined, modern look.
A two-piece toilet consists of a separate bowl and tank, secured together with bolts. All American Standard two-piece bowls feature a sanitary dam—a raised ceramic ledge at the back of the bowl where the tank attaches. This barrier prevents waste and grime from collecting between the tank and bowl, reducing odor-causing buildup.
- Round-front: Compact and space-saving, perfect for small bathrooms.
- Elongated: Boasts an extended bowl shape for enhanced comfort.
American Standard also offers compatible manual and electronic bidet seats for select toilet models, adding extra functionality.
Many users prefer taller toilet bowls for easier sitting and standing. American Standard’s “Right Height” options—with a seat height of 400–430mm from the floor—are ergonomically designed to match the height of a standard chair (350–510mm). This feature is especially beneficial for the elderly, pregnant individuals, and people with mobility challenges.
Toilets come in various dimensions, so measure your bathroom’s available width, depth, and height before purchasing. A critical measurement to check is the rough-in—the distance from the wall to the center of the toilet’s floor bolts. Most toilets use a 12-inch rough-in (excluding baseboards). Always measure first to ensure a proper fit.
