6 Best 10-inch Rough-in Toilets Reviewed
A 10-inch rough-in toilet is only unique in a few ways from a standard rough-in toilet.
The selection is considerably smaller, although we found six models that are suitable for any bathroom regardless of the décor.
1. KOHLER Highline Comfort Height Toilet
PROS
- Class 5 flushing tech
- ADA-compliant
- Elongated bowl
- Excellent MaP score
CONS
- No seat included
Homeowners interested in a stylish toilet have always been partial to KOHLER and their extensive lineup of commodes.
While they have colors and sizes to suit everyone’s needs, the Highline comfort height toilet is our top choice in the 10-inch rough-in category.
While stylish, one of the best features of this two-piece toilet lies inside the tank with the Class Five flushing technology.
It includes a 3.25-inch flush valve and a powerful siphon that leaves a clean bowl behind with every flush. The toilet has a MaP score of 1,000 but is one of the more efficient models on our list.
KOHLER’s engineers were able to achieve the score despite the fact the Highline only uses 1.28 gallons per flush.
The Highline is a comfort height toilet at 16.5 inches without a seat and has an elongated bowl. The company’s patented DryLock system ensures this toilet is a breeze to install.
It’s hard to find a fault with this two-piece toilet, which is one of the reasons it’s been so well-received by homeowners. The Highline has more than enough power to clear the bowl, is easy to install, and efficient.
You’ll need to pick up a seat, supply lines, and installation accessories for this 10-inch rough-in toilet, however.
2. American Standard Cadet Pro Toilet
PROS
- Comfort height
- PowerWash rim
- 3-inch flush valve
- 1.6 GPF
CONS
- No seat or accessories
One-piece toilets have gained a lot of ground in recent years, but there’s something to be said for reliable, traditional styles.
That’s what you’ll find with the Cadet Pro from American Standard, an excellent 10-inch rough-in toilet.
This elongated toilet provides extra room in the front for men and women. It’s a classic two-piece toilet with a partially exposed trapway and chrome-plated trip lever.
There’s ample water surface area in the bowl, and their EverClean surface coating helps keep the inside and outside clean.
With a flush rating of 1.6 GPF, this toilet moves more water than most. The 3-inch flush valve helps the Cadet Pro achieve a MaP score of 1,000 as well. The toilet is chair height at 16.5 inches but does not come with a seat or wax ring.
While not the cheapest two-piece toilet from the company, the Cadet Pro 10-inch rough-in toilet has a powerful flushing mechanism and more than enough water in the bowl to keep it streak-free.
The build quality is top-notch, and homeowners found it as easy to install as our top choice.
3. Swiss Madison Well Made Forever Ivy Toilet
PROS
- Streamlined design
- Dual-flush mechanism
- 3-inch trapway
- Complete installation kit
CONS
- Too small for some
One of the more affordable 10-inch rough-in toilets comes from Swiss Madison, a company known for its budget-friendly designs. The Ivy not only has an attractive price tag but comes with dual-flush capabilities as well.
The design of this toilet allows homeowners to save space and water. It’s dual-flush rated at 1.1 gallons per flush for liquid waste or 1.6 GPF when you need a full flush.
Swiss Madison’s Vortex flush system helps power this commode which has a 2-inch valve but a 3-inch trapway.
This 10-inch rough-in toilet is one of a handful sporting a modern design. The toilet tank flows into the bowl, and the trapway is fully enclosed.
It’s sleek, although not in the comfort height class. The Swiss Madison Well Made Forever Ivy is a little over 15.5 inches tall without the quick-release seat attached.
When you need a complete rough-in toilet for a 10-inch system, the Ivy is well worth a look. It’s easy to maintain and has a flushing score of 600, but it may not be large enough for some people considering its height and design.
This compact toilet comes with a soft-closing toilet seat, wax ring, caps, and a bolt kit.
4. American Standard Cadet 3 Flowise Toilet
PROS
- Efficient at 1.28 GPF
- EverClean glazing
- Compact round bowl
- The price tag
CONS
- It doesn’t come with a seat
- Could be too short
Taller toilets with extended bowls aren’t hard to find whether you want a standard rough-in toilet or one designed for a 10-inch drain.
When you want a toilet with a round bowl, the selection is slimmer, which is where the Cadet 3 Flowise stands out.
This is a round front toilet, so there’s more space between the front of the bowl and the wall. The round bowl is easier for children to use, but so does the height.
This version of the Cadet 3 is 15 inches without a seat making it ideal for people of average height or shorter.
The Cadet 3 10-inch rough-in toilet has a slightly different style than the Pro, although both are two-piece toilets with identical MaP scores.
It’s gravity-fed with a PowerWash rim, and WaterSense certified at 1.28 gallons per flush.
This American Standard toilet won’t break the bank and provides more space in small bathrooms than elongated models.
It’s also more efficient than the Cadet Pro if you live in an area with water restrictions or want to cut back on consumption in your household.
4. TOTO Drake G-Max Toilet
PROS
- G-Max flushing system
- Universal height toilet
- 3-inch valve
- SanaGloss Coating
CONS
- No seat included
When looking for a well-built toilet with a modern style, TOTO has always been a brand homeowners can turn to.
They also have one of the larger selections of 10-inch commodes, including our favorite 10-inch rough-in toilet, the Drake.
This siphon jet toilet takes advantage of TOTO’s G-Max flushing technology. I
