SUPERFLO Rear Outlet Toilet With 19 Inch Tall Bowl
The SUPERFLO model features a 19-inch tall bowl height, delivering increased comfort for seniors or users with limited mobility. This rear discharge toilet supports both rear drain and wall drain configurations, expanding installation flexibility. A suggested upgrade with a macerator pump broadens possible setups, particularly where drainage pathways are not conventional. The dual flush system provides a full flush at 1.28 GPF and a reduced flush at 0.8 GPF, combining comfort with water efficiency for everyday use.
Key considerations include ensuring the bathroom’s plumbing matches a rear-discharge setup, and evaluating whether the 19-inch height aligns with the user’s reach and standing/kneeling needs. The P-Trap compatibility supports odor control and seal integrity, while the option to pair with additional accessories may help adapt to varied bathroom layouts.
Simple Project Rear Outlet Toilet With Tank, 19 Inch ADA Rear High Toilet
This model emphasizes accessibility with a 19-inch tall rear outlet design, which can reduce strain on the waist and knees. It is particularly suited for seniors, handicapped users, or individuals with joint stiffness. The P-Trap design ensures efficient waste flow and forms a water seal that minimizes odors. Note that proper installation depends on accurately measuring the distance from the bathroom floor to the center of the rear drain; mismatches can affect stability and drainage performance. Combined with a possible macerator pump, it supports a wider range of layouts.
The toilet’s dual-flush feature lets users choose between higher and lower water usage per flush (0.64/1.28 GPF). This balance helps conserve water while maintaining reliable flushing power. When selecting this model, verify the rough-in and drain configurations in the bathroom to prevent installation issues or wobble after mounting.
Skirted & Elongated Rear Outlet Toilet With 7″ Rough-In
This model blends space-saving design with comfort, featuring a 7″ rough-in and a 3″ outlet diameter for efficient rear-outlet plumbing. The skirted exterior and elongated bowl provide a contemporary look and improved hygiene with a smooth interior surface. A high-performance Tornado flush system delivers a powerful 1.28 GPF flush, satisfying both efficiency and reliability. The soft-close seat enhances user experience and reduces bathroom noise, creating a calmer atmosphere for daily use.
The 16.5″ height, combined with a back discharge configuration, makes this option suitable for compact bathrooms where space is at a premium. Consider whether the 3″ outlet and 7″ rough-in align with your existing plumbing and whether the extended extension pipes included will fit your wall-drain setup.
ARES 18″ Tall Rear Outlet Toilet
The ARES rear discharge toilet delivers ADA-compliant comfort height with an 18-inch tall bowl and an 18.5-inch elongated bowl, making it accessible for a wide range of users. Two included P-Trap connectors and a back-mount installation design simplify the setup, with compatibility for common PVC or ABS couplings and an adjustable rough-in for precise fitting. The rimless, 360° flush system enhances cleaning efficiency and reduces potential residue, supporting a hygienic bathroom environment and water-saving operation.
When evaluating installation, check the back-mount design compatibility with your plumbing walls and the space available behind the toilet for connecting pipes. The rimless flush can offer easier maintenance, though the absence of a rim may influence your cleaning routine, especially in households with limited mobility or cleaning restrictions.
Rimless Flushing Rear Outlet Toilet With Tank
This skirted, elongated two-piece rear discharge toilet features an 18″ tall height and an 18.5″ elongated bowl, designed for convenience and modern aesthetics. It is suitable for wall-drain configurations, utilizing a P-Trap and offering two extension pipes to accommodate different installation needs. The 1.28 GPF flush is designed to conserve water while delivering reliable waste removal, and the overall rimless flush system promotes a thorough cleaning process with less buildup over time.
Installation flexibility is a key benefit here, with wall-drain adaptability and the option to use two extension pipes. For households upgrading to a rear-discharge system, this model provides a balance of height, ease of use, and efficient flushing. Ensure the bathroom has adequate wall access and that the rough-in distance aligns with the 7″ standard or your chosen extension configuration.
Buying Guide: Key Purchase Considerations For Rear Discharge Toilets With Tanks
- Height and accessibility: Look for 18–19 inch bowl heights for easier standing and seating, especially for seniors or users with mobility challenges. Consider elongated bowls for additional seating area and comfort.
- Rear drainage compatibility: Confirm whether your bathroom uses rear drain or wall drain configurations. Check the proposed P-Trap design compatibility and the rough-in distance to ensure a proper fit.
- Flush performance and water use: Evaluate flush efficiency (commonly 1.28 GPF or less) and whether the toilet offers a dual-flush option. Rimless designs can offer easier cleaning, while Tornado or powerful flush mechanisms can improve waste removal.
- Installation flexibility: Some models include extension pipes and multiple P-Trap connectors. Assess whether wall access, floor clearance, and plumbing exist to support back-discharge installation without major remodeling.
- Comfort features: Soft-close seats, skirted designs, and easy-to-clean surfaces can reduce maintenance time and improve the user experience. Consider whether the seat height is compatible with caregivers’ needs if assistance is common.
- Durability and warranty: Check material quality, liner durability of the tank, and warranty coverage. A two-piece design can simplify replacement parts, while a single-piece unit may offer a sleeker look and easier cleaning.
- Maintenance considerations: Rimless flushing systems and accessible tank-fill mechanisms can simplify daily cleaning. Evaluate the availability of replacement parts in your region to minimize downtime.
- Noise and comfort: Soft-close seats reduce slamming and noise. For shared bathrooms, consider models with quiet dual-flush operations to preserve a calm environment.
In sum, selecting a rear discharge toilet with a tank requires balancing height, installation compatibility, and water efficiency. By focusing on models with proven flush performance, flexible drain options, and reliable accessibility features, shoppers can identify options that deliver long-term comfort and cost savings.
