Let’s explore why the HOROW T0338W might be the best choice for your next toilet upgrade.

1. Perfect Fit for 12-Inch Rough-In Installations

Most homes in the U.S. feature a 12-inch rough-in, which is the distance between the wall and the center of the toilet’s drainpipe. The HOROW T0338W is specifically designed for this standard measurement, ensuring it fits easily into most residential bathrooms without requiring plumbing modifications.

This makes it an ideal replacement for older toilets that may lack modern water-saving features or ergonomic design. It installs quickly, even for those with basic DIY skills.

2. Dual Flush Technology for Water Efficiency

Water conservation is more important than ever, and the HOROW T0338W delivers with its dual flush system. With two flush options—0.8 gallons per flush (GPF) for liquid waste and 1.28 GPF for solids—you can drastically reduce your household’s water usage without sacrificing performance.

This feature is EPA WaterSense certified, which means the toilet meets rigorous water-efficiency and performance standards. Over time, the HOROW T0338W can help reduce your water bill while contributing to a more sustainable lifestyle.

3. One-Piece Design: Modern, Seamless, and Easy to Clean

Unlike two-piece toilets, where the tank and bowl are separate, the HOROW T0338W features a single, seamless construction. This design offers several advantages:

Aesthetically pleasing: Its modern, minimalist look fits seamlessly into contemporary bathroom designs.

Fewer crevices: With fewer joints and seams, there’s less chance for dirt, bacteria, and mold to accumulate.

Easier cleaning: Simply wipe down the smooth surface—no hard-to-reach spots between tank and bowl.

If you're tired of scrubbing around awkward seams and bolts, this one-piece toilet will be a breath of fresh air.

4. Comfort Height for Better Accessibility

Standard toilets often sit too low, making them uncomfortable for taller users or those with mobility challenges. The HOROW T0338W is built with a comfort height seat, roughly 17 to 18 inches from the floor, which makes sitting down and standing up easier.

This feature is especially beneficial for:

• Seniors

• People with back or knee issues

• Anyone who values ergonomic design

It’s also compliant with ADA (Americans with Disabilities Act) guidelines, making it a great choice for universal bathroom design.

5. Quiet, Powerful Flush Every Time

Despite its low water usage, the HOROW T0338W offers a surprisingly powerful flush. Thanks to its siphon jet flushing mechanism, waste is removed efficiently and quietly. You won’t have to worry about double flushing or noisy water flow that disrupts your home’s peaceful environment.

The toilet’s fully glazed trapway prevents clogs and ensures smooth waste removal. It’s an excellent balance between efficiency and reliability.

6. Compact Yet Comfortable Design

Measuring only 25 inches deep, the HOROW T0338W is ideal for small bathrooms, powder rooms, or apartments where space is at a premium. Despite its compact footprint, it still offers a full-sized bowl and comfortable seating experience.

This makes it a favorite among:

• Urban homeowners

• Tiny home builders

• RV and cabin renovators

If you're short on space but don’t want to sacrifice quality or comfort, this toilet is a top contender.

7. Easy Installation and Maintenance

Installing the HOROW T0338W is a straightforward process, especially for those replacing an existing 12-inch rough-in toilet. The package includes:

• All necessary hardware

• A soft-close seat (pre-installed)

• Installation instructions

Once installed, maintenance is minimal. The soft-close seat prevents slamming and extends the toilet’s lifespan, while the glazed surface resists stains and buildup.
