Best 10-Inch Rough-In Toilet: HOROW T37 Tankless Smart Toilet Review

The HOROW T37 has quickly become one of the most popular 10-inch rough-in smart toilets for modern homes across Canada and the USA. Combining a tankless design, automatic flush system, and sleek aesthetics, the T37 fits perfectly in compact bathrooms without compromising performance or comfort.

What Makes the HOROW T37 the Best 10-Inch Rough-In Toilet?

Most traditional toilets require a 12-inch rough-in, but many Canadian and U.S. apartments, condos, or older homes still feature a 10-inch setup. Finding a modern, smart toilet that fits this measurement—and performs reliably—can be challenging. That’s where the HOROW T37 stands out.

• Compact tankless design saves wall space while maintaining strong flush performance.
• Automatic dual-flush system conserves water and ensures powerful waste removal.
• Smart functions like seat sensor, soft-close lid, and warm water wash elevate comfort.
• Modern aesthetics fit minimalist and contemporary bathroom styles.

HOROW T37 Specifications

Design and Build Quality

The T37 features a one-piece, tankless ceramic body that enhances both style and hygiene. Without a bulky tank, cleaning becomes easier and space is maximized—especially important for smaller bathrooms. The smooth curves and minimal edges align with modern interior trends seen in upscale Canadian and U.S. condos.

The build quality feels premium, with durable ceramic and high-quality internal valves designed for consistent operation under variable North American water pressure.

Smart Features Overview

The HOROW T37 is more than a toilet—it’s a comfort appliance. Here’s what sets it apart:

• Automatic Flushing: The seat sensor detects use and activates an auto flush when you leave—hands-free and hygienic.
• Bidet Functions: Adjustable rear and feminine wash modes with temperature control ensure optimal comfort.
• Self-Cleaning Nozzle: The stainless nozzle automatically rinses before and after each use.
• Heated Seat: Perfect for cold Canadian mornings.
• Night Light: Soft LED illumination for nighttime convenience.
• Energy-Saving Mode: Automatically lowers seat temperature when not in use.

Performance and Water Efficiency

The T37’s tankless design connects directly to your home’s water line, allowing instant, high-pressure flushing without a tank refill. Despite its power, the dual-flush system optimizes water use—consuming as little as 1.1 gallons per flush for liquid waste and 1.6 for solids.

Its built-in backflow prevention also meets North American standards, ensuring safety and compliance.

Installation Guide for 10-Inch Rough-In Bathrooms

Installing the HOROW T37 requires attention to detail but is manageable with standard tools or a plumber’s help. Follow these general steps:

1. Shut off the main water supply and remove your old toilet.
2. Confirm your flange distance is 10 inches from the wall to the center of the outlet.
3. Position the HOROW T37, align the mounting holes, and secure the base with included bolts.
4. Connect the water inlet and electrical outlet (a nearby 120V GFCI outlet is required).
5. Power on and test automatic flushing, nozzle operation, and heating functions.

Pros and Cons of the HOROW T37

Compared to traditional tank toilets, the HOROW T37 offers significant advantages:

Real User Experiences

Customer reviews across Canada and the U.S. highlight consistent satisfaction with the T37’s design and ease of use. Many homeowners appreciate how it modernizes their bathroom without requiring a complete remodel. Common praise includes quick flushing, comfortable seat temperature, and elegant design.

Minor feedback notes that while installation is straightforward, having a plumber ensure proper sealing and power setup is worthwhile.

Maintenance and Cleaning

Maintaining the T37 is simple thanks to its one-piece design. The rimless bowl and self-cleaning nozzle reduce bacteria buildup. Use mild, non-abrasive cleaners for the ceramic body and a soft cloth for the bidet seat.

• Clean nozzle weekly using self-cleaning mode.
• Wipe the seat and lid with gentle detergent.
• Avoid bleach or harsh chemicals that damage internal seals.

The HOROW T37 meets CSA and UPC standards, making it fully compatible with Canadian and U.S. plumbing systems. Its design accommodates both high-rise condos and single-family homes that use 10-inch rough-ins—rare in smart toilet models.

Canadians especially value the heated seat and energy-saving modes during long winters, while U.S. homeowners enjoy the modern, minimalist aesthetic for remodel projects.
