A toilet with a 10-inch rough-in is designed for a drain flange located 10 inches from the finished wall. Among these options, the WinZo is best for very tight spaces, the HOROW is best for a taller chair-height seat, and the St. Tropez is best for shoppers who want an elongated bowl. The DeerValley emphasizes a compact footprint and easy-clean skirted design, while the Kohler offers a two-piece configuration. Confirm the toilet’s dimensions and installation requirements before choosing a model.

| Swiss Madison St. Tropez | Elongated-bowl comfort | 10-inch rough-in and dual flush |

HOROW T0338W10 Chair-Height Toilet
The HOROW T0338W10 is a one-piece toilet with a 10-inch rough-in option and an elongated design. Its listed dimensions are 26.6 inches deep, 15 inches wide, and 26 inches high. A top-mounted dual-flush button provides a choice of flushes, and the toilet has a fully glazed 2-inch trapway.
Best for: Buyers who want a higher seat for easier sitting and standing. The listed seat height is 17.3 inches or more from the floor, and the product is described as ADA compliant. Choose it if chair-height seating matters; compare its depth with your available bathroom space before ordering.
DeerValley Compact Skirted Toilet
This one-piece model is listed as a 10-inch rough-in toilet and measures 24½ inches long, 13⅜ inches wide, and 28⅜ inches high. It has a standard-height round bowl and a dual-flush system rated at 1.1 and 1.6 gallons per flush. Its skirted exterior is designed to reduce hard-to-reach crevices during cleaning.
Best for: Small bathrooms where a compact round bowl and streamlined exterior are priorities. The listed seating capacity is up to 250 pounds. Choose it if easy exterior cleaning is important; avoid assuming it provides chair-height seating, since the product description specifies standard seat height.
Swiss Madison St. Tropez Elongated Toilet
The St. Tropez is a one-piece toilet with a 10-inch rough-in and a standard elongated bowl. Its dual-flush controls offer a 1.1 GPF light flush and a 1.6 GPF full flush. The elongated shape provides more room than a round bowl, according to the product description.
Best for: Shoppers who want an elongated bowl in a bathroom with a 10-inch rough-in. It is a better fit when bowl shape is a priority than when a specific seat height or overall depth is the deciding factor. The listed product details do not provide full dimensions, so verify the measurements before purchase.
WinZo WZ5079S Compact Round Toilet
The WinZo WZ5079S is a compact one-piece toilet with a 10-inch rough-in and a round bowl. Its listed projection from the wall is 22.8 inches, and its standard seat height is 16 inches. The dual-flush system offers 0.8 and 1.6 GPF options. A concealed trapway and double-cyclone flushing design are also listed.
Best for: Powder rooms, children’s bathrooms, and other spaces where projection is a major concern. Its stated 22.8-inch depth makes it the shortest option in this comparison based on the provided specifications. Check all dimensions against your installation area; standard seat height may not suit buyers who need a taller seat.
Kohler Highline Two-Piece Toilet
The Kohler Highline KOH3889-0 is a two-piece elongated toilet listed with a 10-inch rough-in and a 1.28 GPF flush. Its separate tank and bowl distinguish it from the one-piece models in this list. The product information says the elongated bowl provides an extra 1½ inches compared with a traditional round bowl and lists a manufacturer’s warranty of up to one year after installation.
Best for: Buyers who prefer a two-piece toilet and want a 1.28 GPF model. The separate components may suit shoppers who prioritize that configuration, but the product listing says it can ease installation and maintenance rather than providing room-specific dimensions. Confirm the full measurements and seat-height details before selecting it.
Buying Guide: How To Choose A Toilet With A 10-Inch Rough-In
How do you measure a 10-inch rough-in?
Measure from the finished wall behind the toilet to the center of the floor drain or closet bolts. A 10-inch rough-in means that distance is 10 inches. Measure from the finished wall, not from the baseboard, and account for any trim that affects how the toilet sits.
Which dimensions should you compare?
Rough-in is only one measurement. Check projection from the wall, width, overall height, and bowl shape. Projection matters in narrow rooms, while bowl shape affects how much front-to-back space the toilet occupies. The WinZo lists a 22.8-inch projection; the DeerValley lists its full compact dimensions. Compare these figures with your available space.
Should you choose a round or elongated bowl?
A round bowl can be useful when saving space is a priority. An elongated bowl may provide more seating room, as noted in the St. Tropez and Kohler product descriptions. Compare the bowl’s footprint with bathroom clearance before deciding.
Does seat height matter?
Yes. The HOROW lists a height of 17.3 inches or more from floor to seat, while WinZo lists a 16-inch standard seat height. The DeerValley description also identifies standard seat height. Check whether the listed measurement includes the seat or cover, and choose based on the needs of the people using the bathroom.
What should you know about dual-flush ratings?
Dual-flush toilets offer different flush options, but their listed rates vary: HOROW does not specify rates in the supplied details, DeerValley and St. Tropez list 1.1/1.6 GPF, and WinZo lists 0.8/1.6 GPF. The Kohler is listed at 1.28 GPF. Compare stated rates and follow the installation instructions for the model you choose.
Frequently Asked Questions
Can a toilet with a 10-inch rough-in fit a 10-inch space?
It is intended for a 10-inch rough-in, but confirm the measurement from the finished wall to the drain center and check the toilet’s full dimensions before buying.
Is a 10-inch rough-in the same as toilet depth?
No. Rough-in is the distance from the finished wall to the drain center. Toilet depth or projection describes how far the installed toilet extends into the room.
Which option is shortest from the wall?
The WinZo WZ5079S lists a 22.8-inch projection from the wall, making it the shortest option in this comparison based on the supplied product details.
Which model has the tallest listed seat?
The HOROW T0338W10 lists a seat height of 17.3 inches or more from the floor.
Should I verify dimensions before installation?
Yes. Check the rough-in, projection, width, height, and required clearances against your bathroom and the product’s installation instructions.
