HOROW T38 vs T38P

HOROW's range includes different seat heights, flushing systems and installation requirements. Compare the exact model specification against your bathroom rather than treating all smart toilets as interchangeable.

Verified HOROW model specifications

These manufacturer-listed figures provide a starting point for comparing models. A product page and installation manual take precedence over this summary.

T38 and T38P: the practical differences

The T38 lists a 16 9/16-inch seat height and 1.06 GPF flush. The T38P lists a 17.56-inch seat height and 1.0/1.28 GPF dual flush. Both list a 12-inch rough-in and 16 A at 120 V. Compare the latest drawings for clearance, and confirm whether any outage-flush accessory is included.

Manufacturer documents

Before you buy

Confirm the current price, stock, shipping destination, return conditions, included accessories, installer requirements and warranty at checkout. Check current offers and the written terms before purchasing.

The clearest published distinction

HOROW's published specifications list the T38 seat at 16 9/16 inches and the T38P at 17.56 inches. That difference may matter when getting on or off the toilet; check how each measurement is defined and whether the seat is included.

Do not overlook the other specifications

The listed flush volumes differ, and product variants can change over time. Compare the exact manuals for power supply, water pressure, bowl projection, remote features and installation hardware rather than deciding solely on the model suffix.

How to choose for your bathroom

Measure your existing seat height and have intended users try a comparable height if possible. Then confirm the flange distance, outlet location and door clearance for the candidate model. Height preference cannot compensate for a fit problem.

How to verify a product claim

Open the manufacturer's current listing and download the manual for the exact model and variant. Check the specifications table against the installation drawing; marketing headings may group several configurations together. If a measurement, feature or warranty detail is missing, ask the merchant for written clarification before purchasing.

What to budget beyond the fixture

Include delivery access, removal of the old toilet, any required electrical work, plumbing adjustments and disposal. Confirm whether the price includes a seat, remote, mounting hardware and supply accessories. Keep the order confirmation and inspect the ceramic before installation, following the seller's damage-reporting window.

Where the dimensions change the decision

The published T38P seat height is about one inch greater than the T38’s, while their listed lengths and widths are very close. Height may matter more than footprint for someone replacing a lower toilet. Measure your existing seat height, not only the bowl rim, and compare it with the manufacturer’s measurement convention.

Do not assume equivalent flushing

HOROW lists the T38 at 1.06 GPF and the T38P at 1.0/1.28 GPF. Those numbers describe different published flush configurations; they do not by themselves show which toilet clears waste more effectively. Compare the current manuals and any independently certified performance data.
