No listed toilet has an 11-inch rough-in: four are designed for a 10-inch rough-in, and one is designed for 12 inches. For an 11-inch measurement, verify the manufacturer’s installation specifications and available clearance before choosing. Among the options, HOROW is best for chair-height seating, St. Tropez for an elongated bowl with dual flush, Sublime II for a compact round bowl, and American Standard for a two-piece design. GIVING TREE is a 12-inch option, so it is not a direct match.
| Toilet | Listed rough-in | Best suited for |
|---|---|---|
| HOROW T0338W10 | 10 inches | Chair-height seating |
| St. Tropez | 10 inches | Elongated bowl and dual flush |
| Sublime II | 10 inches | Compact round bowl |
| American Standard Colony 3 | 10 inches | Two-piece configuration |
| GIVING TREE 6651 | 12 inches | 12-inch rough-in installations |
HOROW T0338W10 Chair-Height Toilet

The HOROW T0338W10 is a one-piece toilet with a listed 10-inch rough-in option. Its 17.3-inch seat height is intended to make sitting down and standing up easier, while the compact elongated design measures 26.6 inches deep, 15 inches wide, and 26 inches high. A dual-flush button and fully glazed 2-inch trapway are also listed features.
Best for: Buyers who prioritize chair-height seating or want an elongated bowl in a compact one-piece design. It was selected for its clearly stated dimensions and height information.
Limitation: Its specified rough-in is 10 inches, not 11. Confirm installation measurements rather than assuming it will fit an 11-inch setup.
St. Tropez Elongated Dual-Flush Toilet

The Swiss Madison St. Tropez is a one-piece toilet with a 10-inch rough-in and an elongated bowl. Its dual-flush controls offer a listed 1.1-gallon-per-flush light flush and a 1.6-gallon-per-flush full flush. The elongated shape is described as providing extra room and comfort.
Best for: Buyers who want an elongated bowl and two flush-volume choices. It is a relevant comparison because it combines a compact rough-in specification with dual-flush operation.
Limitation: The product data specifies a 10-inch rough-in, so it is not confirmed for an 11-inch measurement. Check the installation instructions and bathroom clearances before purchase.
Sublime II Compact Round Toilet

The Swiss Madison Sublime II is a one-piece toilet with a listed 10-inch rough-in, round bowl, and dual top-flush buttons. The flush options are 1.1 gallons per flush for a light flush and 1.6 gallons per flush for a full flush. Its round shape may suit buyers looking to preserve movement space in a bathroom.
Best for: Smaller bathrooms where a round bowl is preferred over an elongated one. It was selected because its bowl style distinguishes it from the other 10-inch options.
Limitation: The listing specifies a 10-inch rough-in, not 11 inches. A round bowl may also be less appealing to shoppers who specifically want the extra room associated with an elongated bowl.
American Standard Colony 3 Two-Piece Toilet

The American Standard Colony 3 is a two-piece toilet with a 10-inch rough-in and elongated-front bowl. Its listed flush volume is 1.28 gallons per flush, and the PowerWash rim design is described as scrubbing the bowl with every flush. The product is sold without a seat, according to its name.
Best for: Buyers seeking a two-piece toilet with a 10-inch rough-in and a stated 1.28-gallon flush. It adds a different configuration to this comparison and includes a bowl-cleaning feature in the product details.
Limitation: The listed rough-in is 10 inches, not 11, and the seat is not included. Confirm whether the installation matches your measured rough-in and plan for a separate seat.
GIVING TREE 6651 Dual-Flush Toilet

The GIVING TREE 6651 is a one-piece toilet with a 12-inch rough-in, not an 11-inch specification. It has an elongated design, a skirted exterior, siphon-jet flushing, and dual-flush options listed at 1.1 and 1.6 gallons per flush. The product details also describe 360-degree glazed pipes.
Best for: Buyers whose measured installation calls for a 12-inch rough-in and who want a skirted design with dual flush. It was included as a nearby rough-in comparison, not as a direct 11-inch match.
Limitation: Its 12-inch rough-in makes it a poor starting choice for an 11-inch measurement unless the manufacturer’s installation guidance confirms the fit.
Buying Guide: Choosing A Toilet For An 11-Inch Rough-In
How should you measure the rough-in?
Measure from the finished wall behind the toilet to the center of the floor drain or closet bolts, following the toilet manufacturer’s measurement instructions. Measure from the finished wall, not the baseboard. If the toilet is already installed, the center point may be hidden; check the installation or fixture documentation when available.
Will a 10-inch or 12-inch toilet fit an 11-inch rough-in?
Do not assume that either size will fit. Rough-in specifications identify the intended distance between the wall and drain connection. The products listed here are specified for 10 or 12 inches, and none is confirmed for 11 inches. Ask the manufacturer or a qualified installer to verify the required clearance and connection details before buying.
Which bowl shape and configuration should you compare?
Choose a round bowl if preserving room in a compact bathroom is a priority. Choose an elongated bowl if you prefer its additional room. One-piece toilets combine the tank and bowl in a single unit; the American Standard option is two-piece. Compare the listed dimensions and installation requirements with the space available.
What else should you check before ordering?
- Confirm the rough-in specification in the installation manual, not only the product title.
- Compare toilet depth and width with the room and door clearance.
- Check seat height if easier sitting and standing is important.
- Review flush volumes and flush-control type if water use is a priority.
- Check whether a seat is included; the American Standard listing says it is less seat.
