Choosing a smart toilet is about more than picking the model with the most features. Your bathroom layout, rough-in size, comfort preferences, flushing needs, hygiene expectations, and budget all play an important role.
Two popular options from HOROW are the HOROW X70 Smart Toilet and the HOROW T38 Smart Toilet. Both are designed for bathrooms with a 12-inch rough-in and feature a built-in tank and pump. However, they offer different approaches to comfort, hygiene, smart functionality, and overall bathroom experience.
So, which one is right for your bathroom? This guide compares the HOROW X70 vs T38 to help homeowners make a more informed decision.

1. Both HOROW Models Are Designed for 12-Inch Rough-Ins
Before comparing smart features, check your bathroom's plumbing configuration.
Both the HOROW X70 and T38 require a 12-inch rough-in. The rough-in is measured from the finished wall to the center of the toilet flange.
This makes either model a potential choice for a standard 12-inch rough-in bathroom, but homeowners should confirm the measurement before ordering.
For a bathroom renovation, don't look at rough-in size alone. Also consider:
- Available floor space
- Door swing
- Wall clearance
- Water-supply location
- Electrical outlet location
- Toilet seat height
- Installation access
2. Flushing Performance: X70 vs T38
Flushing performance is one of the most important considerations when choosing a smart toilet.
HOROW X70
The X70 combines a built-in tank with a 100W pump-assist flushing system. Its flushing system provides 1.0/1.28 GPF dual-flush options, giving users different flush-volume choices.

The built-in pump also helps provide consistent flushing performance in bathrooms where household water pressure may vary.

HOROW T38
The T38 also uses a built-in water tank and pump to support flushing performance. It is rated at approximately 1.06 GPF.

The combination of a tank and booster pump helps the T38 provide a reliable flushing system while also supporting its integrated bidet functions.

Which Has the Advantage?
If flushing control and pump-assisted performance are your priorities, the X70 has a more advanced flushing specification, particularly with its dual-flush configuration and 100W pump assist.
The T38 remains an attractive option for homeowners who want built-in tank-and-pump flushing together with integrated bidet comfort.
3. Bidet and Personal-Cleansing Features
Both toilets provide integrated bidet functionality, so you don't need to purchase a separate bidet seat.
The T38 provides front and rear washing, adjustable water temperature and pressure, multiple cleaning modes, and warm-air drying. Its heated seat also provides adjustable temperature settings for added comfort.
The X70 expands the experience with family-oriented wash modes, including feminine, rear, massage, and child-friendly washing. It also provides adjustable washing and warm-air drying functions.
Choose the X70 if:
- Multiple family members will use the toilet
- You want child-friendly washing
- You prefer more personalized wash modes
- Massage or pulse washing is important
- You want a more comprehensive bidet experience
Choose the T38 if:
- You primarily want front and rear bidet washing
- A heated seat is important
- You want warm-air drying
- You want essential smart bidet functions in a simpler package
4. Hygiene and Bowl-Cleaning Technology
Hygiene is another area where the X70 offers a broader technology package.
The X70 features multiple hygiene technologies, including UVC water treatment, filtration, a self-cleaning nozzle, and Foam Shield technology. Foam Shield is designed to help reduce splash, waste adhesion, bacteria, and odor spread.
The T38 uses UV-assisted nozzle cleaning, a detachable nozzle, and ceramic pre-misting to help reduce waste from sticking to the bowl surface.
For homeowners who place a particularly high priority on automated hygiene technology and bowl cleanliness, the X70 is the more feature-rich choice.
5. Automatic Lid and Flush
Nobody wants to touch a toilet unnecessarily.
Both the X70 and T38 offer hands-free functionality.
The T38 includes an automatic open-and-close lid and automatic flushing after use.
The X70 combines automatic lid opening and closing with automatic flushing, foot-kick control, and smart night lighting.
If touch-free operation is one of your main reasons for upgrading to a smart toilet, both models are strong candidates. However, the X70 provides more ways to control the toilet without touching it.
6. Comfort: Which Toilet Is Better?
Comfort can be just as important as technology.
The T38 features an elongated heated seat, adjustable seat temperature, and warm-air drying for a more comfortable daily experience.
The X70 features a 17-inch ADA-compliant seat height and an elongated design intended to provide comfortable seating. Its additional temperature-control features help customize the washing, seat, and drying experience.
For seniors, taller users, or homeowners specifically looking for an ADA-compliant seat height, the X70 is the stronger choice.
7. Power-Outage Flushing: An Important Difference
A smart toilet relies on electricity for features such as heated seats, bidet washing, drying, automatic controls, and lighting. What happens when the power goes out?
This is one of the most important differences between the X70 and T38.
X70: Mechanical Emergency Flush
The X70 includes a mechanical emergency flush system. This provides a way to flush during a power outage without relying on the toilet's normal electronic functions.
T38: Battery Backup Option
The T38 supports manual blackout flushing when a compatible battery pack is installed. This gives homeowners an additional option for maintaining flushing capability during a power interruption.
For households where power interruptions are a concern, the X70's integrated mechanical emergency-flush approach may be more convenient.
8. Smart Lighting and Bathroom Atmosphere
If bathroom ambience matters to you, the T38 has an especially appealing feature package.
The T38 includes mood lighting and intelligent night lighting, helping create a more relaxing and visually distinctive bathroom experience.

The X70 also includes a smart night light designed to provide convenient nighttime visibility without requiring the main bathroom light.
If your priority is decorative bathroom ambience, the T38 is worth considering. If lighting is one part of a larger smart-toilet feature package, the X70 provides a broader overall system.
