HOROW T0338W-10 Review: The Best 10-Inch Rough-In One-Piece Toilet in Canada

If you live in Canada and have a small bathroom or an older home, chances are you’ve faced one of the biggest bathroom renovation challenges: finding a reliable 10-inch rough-in toilet. Most modern toilets are built for a 12-inch rough-in, leaving homeowners with limited options, especially when they want a toilet that’s compact, stylish, efficient, and built to last.

That’s exactly why the HOROW T0338W-10 one-piece toilet has become one of the most popular picks across Canada. This toilet combines a compact design with powerful flushing, water-saving performance, durable ceramic quality, and a sleek, modern look—without the high price tag seen in many premium brands.

In this in-depth review, we will explore every detail about the HOROW T0338W-10, including its features, performance, design, installation, pros and cons, and how it compares to other 10-inch rough-in toilets available in Canada.

Why Is the Rough-In Size So Important?

Before diving into the toilet itself, let’s clarify why the rough-in size matters. The rough-in is the distance from the wall behind the toilet to the center of the drainpipe. Most common rough-ins are 12 inches, but older Canadian homes—especially those built before the 1990s—often have 10-inch rough-ins.

Choosing the wrong rough-in means your toilet won’t fit properly, may cause plumbing issues, or will require expensive renovations. That’s why homeowners with 10-inch rough-in bathrooms often search for toilets that fit perfectly, flush reliably, and still look modern.

The HOROW T0338W-10 solves all of these challenges, offering a 10-inch rough-in toilet that looks just as stylish and high-performing as standard 12-inch options.

This toilet is specifically engineered for Canadian homes needing a reliable, stylish, space-saving solution.

Design & Build Quality

The HOROW T0338W-10 features a sleek, compact, and seamless one-piece design. Unlike two-piece toilets, which have a gap between the tank and bowl where dirt and mold collect, this one-piece model offers a smooth, easy-to-clean surface.

Compact Size Perfect for Small Bathrooms

Canadian homes—especially condos, basement suites, and older houses—often have smaller bathrooms. The T0338W-10 is built with a shorter depth and narrow profile to maximize space. Despite its compact footprint, the seating height and bowl shape remain comfortable for adults.

Premium Ceramic Glazing

The toilet uses high-density vitreous china with a glossy glaze that resists stains, odors, bacteria, and scratches. This finish keeps the toilet looking new for years with minima  maintenance.

Slow-Close, Quick-Release Seat

The included soft-close seat prevents slamming noises and increases durability. The quick-release mechanism makes cleaning around the hinges effortless.

Flushing Performance

Flushing power is one of the most important factors when choosing a toilet. The HOROW T0338W-10 excels here thanks to its high-efficiency siphon flushing system.

Dual Flush System

• 0.8 GPF for liquid waste
• 1.28 GPF for solid waste

This allows homeowners to reduce water usage without compromising flushing strength—an important benefit in areas with rising utility costs.

Fully Glazed Trapway

The fully glazed trapway ensures waste moves smoothly through the drain, reducing the risk of clogs. Many users report that they never experience clogs with this toilet, even after heavy use.

Quiet but Powerful

Unlike older toilets that are loud and harsh, the T0338W-10 flushes quietly but effectively, making it ideal for shared homes, nighttime use, or bathrooms close to bedrooms.

Installation Experience

The HOROW T0338W-10 is designed to make installation easier, even for those with tight spaces. The 10-inch rough-in fits older plumbing layouts without remodeling.

What Installers Love

• Comes with a full installation kit
• Lightweight for a one-piece toilet
• Includes wax ring, bolts, and seat
• Easy access for tightening bolts

Most homeowners hire a plumber, but many DIY-savvy customers find the installation straightforward, taking about 1–2 hours.

Water Efficiency & Savings

With water rates rising across Canada, the dual-flush system helps reduce utility bills. Compared to older 3.5 GPF toilets, the HOROW T0338W-10 can cut bathroom water usage by more than half.

Even the full 1.6 GPF flush is efficient and meets North American standards for performance and conservation.

Comfort & Convenience

Ergonomic Height & Bowl Shape

Although compact, the toilet maintains a comfortable seat height that supports a natural sitting posture. The elongated round-front bowl ensures comfort while still saving space in small bathrooms.

Clean, Hygienic, and Low-Maintenance

The smooth ceramic glaze reduces the need for frequent scrubbing. The one-piece design eliminates gaps where dirt and mildew accumulate. The quick-release seat also helps keep hard-to-reach areas clean.
