This is the only dual flush in the pool, with a 1.1-gallon reduced mode and a 1.6-gallon full flush, and it combines that with a one-piece body and an elongated bowl.

Good fit if

How the picks were chosen
The pool for this guide is the set of toilets in the catalogue that list a 14-inch rough-in. That set contains 3 models, and all three are included here, since that is the full selection of 14-inch rough-in units currently tracked. The comparison is based only on what the listings state: flush type, gallons per flush, bowl shape, construction, and finish. No individual at this site has installed or used these toilets; the selection is based on the seller's stated specifications and the maker's published information. Prices are live: the page reads the current listing price with the clock time each time it loads, and the number shown is what the seller quotes at that moment. The rankings and awards reflect the specs as listed, and they may change if a listing is revised.
Picking the right one for you
What a 14-inch rough-in means
The rough-in is the distance from the finished wall behind the toilet to the center of the floor flange, the fitting on the floor drain that the toilet bolts to. Twelve inches is the common standard in most modern homes. A 14-inch rough-in is less common and usually appears in older houses or remodels where the drain was placed farther from the wall. Measure your own spacing from the wall to the center of the flange bolts before ordering: a 14-inch unit will not line up with a 12-inch flange. All three picks in this guide are built for the 14-inch spacing.
Gallons per flush and WaterSense
Toilets are the largest single source of indoor water use, accounting for nearly 30 percent of a home's indoor water consumption according to EPA. The federal standard allows up to 1.6 gallons per flush. A WaterSense labeled toilet uses 1.28 gallons or less, about 20 percent less than the federal standard. In this pool, the two single-flush picks are listed at 1.28 gallons per flush, and the glossy white dual-flush model adds a 1.1-gallon reduced mode for liquid waste. None of the seller listings states whether each unit is WaterSense certified, so treat the GPF numbers as the comparison point.
Elongated or round bowl
Bowl shape decides how much floor space the toilet needs and how much sitting surface it offers. An elongated bowl is oval and longer front to back, giving more support, but it requires more clearance in front of the toilet. A round bowl is shorter and fits tighter bathrooms. In this list, both St. Tropez models are elongated, while the Signature Hardware Bradenton is round. If the bathroom is very small, the round Bradenton keeps more floor space open; if comfort matters more, choose an elongated bowl. Bowls in both shapes are available in the same rough-in, so shape is a decision about the room, not about fit.
One-piece or two-piece construction
One-piece toilets mold the tank and bowl as a single body with no seam, so the base is easier to wipe down and there is no horizontal ledge where grime collects. Two-piece toilets have a separate tank that sits on the bowl with a visible seam, a more traditional look and typically a lighter tank to handle during installation. Two of the three picks, both St. Tropez models, are one-piece; the Signature Hardware Bradenton is the only two-piece here. Your choice comes down to whether you prefer the seamless cleaning and modern appearance of a one-piece or the conventional silhouette and easier tank separation of a two-piece.
Questions
What does a 14-inch rough-in mean for toilet installation?
A 14-inch rough-in is the distance from the finished wall to the center of the floor drain flange. Most homes use a 12-inch rough-in, so a 14-inch model is a specialty fit for older houses or custom layouts. You must measure your rough-in accurately before buying, because a toilet built for 14 inches will not align with a 12-inch flange without moving the drain pipe.
Is a 1.28 gallons per flush toilet water efficient?
Yes. The federal standard allows up to 1.6 gallons per flush, and 1.28 gallons is about 20 percent less. That is the threshold EPA uses for WaterSense labeled toilets. Both single-flush picks in this guide list 1.28 GPF, and the dual-flush St. Tropez has a 1.1-gallon reduced mode for liquid waste, which pushes efficiency even further.
Which bowl shape is better for a small bathroom?
A round bowl extends less into the room, so it gives more clearance in front of the toilet. In this list, the Signature Hardware Bradenton is the round option. If you prioritize sitting comfort over space, an elongated bowl, like on the St. Tropez models, provides a longer surface. Measure your bathroom's available depth and choose accordingly.
Do any of these 14-inch rough-in toilets include the seat?
None of the seller listings states that a toilet seat is included. You should plan to buy a separate seat, typically a standard round or elongated seat matching the bowl shape. Check the product page before ordering to confirm whether a seat is included, and always verify the bowl shape to get the correct seat size.
