How to Choose the Best Toilet Bowls
Understanding Toilet Configuration: One-Piece vs. Two-Piece
The primary distinction in toilet bowls often lies in their configuration: one-piece or two-piece. Two-piece models, like the PROFLO PFCT300HE, feature a separate tank and bowl, which can simplify installation and replacement of individual components. This design typically allows for easier access to the area around the toilet during cleaning or maintenance. Conversely, one-piece toilets, such as the DeerValley Elongated One Piece and the CASTA DIVA Compact One Piece, integrate the tank and bowl into a single seamless unit. This unified construction eliminates crevices between the tank and bowl, making them notably easier to clean and often lending a more contemporary aesthetic to the bathroom space. Users report that the lack of gaps reduces grime accumulation significantly.
Optimizing Comfort and Space with Bowl Shape and Height
Bowl shape and height are critical factors influencing user comfort and bathroom layout. Elongated bowls, exemplified by the American Standard 3437C101.020 and the DeerValley Elongated One Piece, generally offer more seating surface and are often preferred for adult users due to enhanced comfort. These typically measure around 16.5 to 17 inches in rim height, falling into the 'comfort height' or 'chair height' category, which aligns with standard chair heights for easier sitting and standing. In contrast, round bowls, like those found in the CASTA DIVA Compact One Piece, are shorter and project less from the wall, making them ideal for smaller bathrooms where space optimization is a priority. The choice between shapes depends heavily on available space and user preference for comfort versus compactness.
Evaluating Flushing Performance and Water Efficiency
Modern toilet bowls are designed with varying flush technologies and water efficiency ratings. The Gallons Per Flush (GPF) indicates water consumption, with 1.28 GPF being a common high-efficiency standard, as seen in the PROFLO PFCT300HE. Many contemporary models, including the DeerValley Elongated One Piece and the CASTA DIVA Compact One Piece, utilize a dual-flush system, offering both a lower (e.g., 1.1 GPF) flush for liquid waste and a higher (e.g., 1.6 GPF) flush for solid waste. This system typically results in substantial water savings over time. Beyond GPF, the Maximum Performance (MaP) rating, often found in specifications for models like the CASTA DIVA with its MAP 1000g, quantifies the amount of solid waste a toilet can clear in a single flush, indicating robust performance and minimizing the need for multiple flushes.
Design Aesthetics and Maintenance Features
Beyond core functionality, design elements contribute to both the visual appeal and ease of maintenance of a toilet bowl. Skirted designs, present in the CASTA DIVA and DeerValley Compact One-Piece toilets, feature a smooth, seamless base that conceals the trapway. This design not only offers a sleek, modern look but also eliminates the nooks and crannies where dust and grime typically accumulate, making cleaning significantly easier. Features like quick-release soft-close seats, common on DeerValley models, enhance user experience by preventing slamming and simplifying seat removal for thorough cleaning. The overall integration of tank and bowl in one-piece units also contributes to a cleaner, more streamlined appearance compared to traditional two-piece configurations.
Pros & Cons
PROFLO PFCT300HE 1.28 GPF Two Piece Round Toilet with Left Hand Lever - 15-3/4" Tall Bowl - White
Pros
- Two-piece configuration allows for easier component replacement and handling during installation.
- Limited lifetime warranty on the fixture provides long-term assurance for the main component.
- Standard 1.28 GPF flush offers a balance of water efficiency and proven performance.
Cons
- Round bowl shape may offer less comfort compared to elongated designs for some users.
- Two-piece design can create more areas for grime collection compared to seamless one-piece models.
American Standard 3437C101.020 Colony 3 Elongated Toilet Bowl, White
Pros
- Elongated bowl shape provides enhanced comfort, particularly for adults.
- 16-1/2" rim height offers a 'comfort height' experience, aiding in ease of use for sitting and standing.
- Sanitary bar feature is designed to prevent grime accumulation under the tank, simplifying cleaning.
Cons
- Sold as 'bowl only,' requiring separate purchase of a tank and seat, which adds complexity to selection.
- The tank-to-bowl connection, being a two-piece design, may still present areas for potential grime buildup compared to one-piece units.
DeerValley Elongated One Piece Toilet with Standard Height Quick Release Seat Dual Flush 1.1/1.6 GPF White 12" Rough In Bathroom Toilet
Pros
- Ergonomic comfort design with nearly 17-inch seat height and elongated bowl enhances user comfort.
- High-efficiency dual-flush system (1.1/1.6 GPF) offers water savings without compromising flush power.
- Integrated premium soft-close seat with rust-proof stainless steel hinges provides quiet operation and durability.
Cons
- One-piece design, while easy to clean, can be heavier and more challenging to maneuver during installation.
- Specific 12" rough-in requirement may not be compatible with all existing plumbing setups.
Common Mistakes to Avoid
Overlooking Rough-In Measurement
A common oversight when selecting a toilet bowl is not verifying the rough-in measurement. This critical dimension, typically 12 inches as specified for the DeerValley Elongated One Piece, refers to the distance from the finished wall to the center of the drainpipe. Incorrectly measuring or assuming a standard rough-in can lead to installation complications, requiring costly modifications or a different toilet. Always measure this distance accurately before purchase.
Neglecting Bowl Shape and Height for Comfort or Space
Users often prioritize aesthetics over functional fit, leading to discomfort or spatial issues. For instance, while the American Standard 3437C101.020 offers an elongated shape and 16-1/2" rim height for comfort, installing such a model in a very compact bathroom might impede movement. Conversely, opting for a compact round toilet like the CASTA DIVA in a primary bathroom might compromise the comfort desired by taller users. Matching the bowl shape and height to both user needs and bathroom dimensions is essential.
Underestimating the Importance of Flush Performance
Many assume all toilets flush equally, but performance varies significantly. Relying solely on GPF without considering the MaP rating, like the MAP 1000g of the CASTA DIVA, can lead to dissatisfaction. A toilet with a lower MaP rating, even with a high-efficiency GPF, might struggle with effective waste removal, potentially increasing water usage due to repeated flushing. For example, a 1.28 GPF PROFLO toilet performs differently than a dual-flush DeerValley system in practice.
Forgetting Essential Components for Bowl-Only Purchases
When selecting a 'bowl only' option, such as the American Standard 3437C101.020, a frequent mistake is forgetting that the tank, seat, and often the wax ring and bolts, must be purchased separately. This can lead to delays in installation and unexpected additional costs. Always confirm what components are included and what needs to be acquired independently to ensure a complete setup.
