Our Picks: Best Elongated Comfort Height Toilet reviews
MAXSA 15-Inch Elongated Two-Piece Toilet: Best for Height Options
The MAXSA is a two-piece toilet with a 1.28 GPF siphonic flush, a soft-close seat, and a side-mounted handle. Its listing describes four configurations: 15-inch round, 15-inch elongated, 15.4-inch elongated, and 16.3-inch elongated ADA. That range gives you options, but it also makes it important to confirm which version is selected before ordering.
The included wax ring and installation hardware can be handy for a replacement project, and the standard 12-inch rough-in fits many residential layouts. Its vitreous china surface has a smooth, glossy finish intended to make routine cleaning easier. The main caution is height: the 15-inch version is not the same as a typical elevated comfort-height toilet. If a higher seat is your priority, check whether the 16.3-inch option is available and confirm its measurements.
Pros:
- Several bowl and height configurations are listed.
- Uses 1.28 gallons per flush.
- Includes a soft-close seat, wax ring, and installation hardware.
- Standard 12-inch rough-in.
Cons:
- The 15-inch version may feel low if you specifically need an elevated seat.
- You need to verify the selected configuration before checkout.
Verdict: Choose the MAXSA if you want a basic elongated toilet with several listed size options, but confirm the exact height because the 15-inch version is not especially tall.
Kohler Highline: Best for a 10-Inch Rough-In
This Kohler Highline is a two-piece elongated toilet with a 1.28 GPF flush and a 10-inch rough-in. That rough-in is its standout feature: it may suit a bathroom where the distance from the finished wall to the waste outlet does not match the more common 12-inch layout. Measure before ordering, since the wrong rough-in can make a toilet incompatible with your plumbing.
The vitreous china construction and simple design offer a familiar look, while the elongated bowl provides more front-to-back room than a traditional round bowl. The supplied product details do not specify the seat height or list included installation parts, so check those points if they matter to your project. Compared with the other picks, this is the clearest option for a 10-inch rough-in, but it offers less height detail in the available specifications.
Pros:
- Designed for a 10-inch rough-in.
- Elongated bowl offers more room than a round bowl.
- Two-piece design can ease installation and maintenance.
- Vitreous china construction.
Cons:
- Seat-height details are not provided in the supplied specifications.
- Its 10-inch rough-in will not fit every bathroom layout.
Verdict: Consider the Highline when your bathroom specifically calls for a 10-inch rough-in, and verify the seat height and installation requirements before buying.
Los Flexi 17.9-Inch ADA Toilet: Best for a Raised Seat
This Los Flexi two-piece toilet pairs an elongated bowl with a height described as 17 inches and ADA-compliant in the product details. Its listing title also refers to a 17.9-inch toilet, so check the exact measurement and how it is measured before ordering. A higher seat can be helpful for some people when sitting down or standing up, but comfort is personal and depends on your height and mobility needs.
The toilet uses a 360-degree siphon flushing system and includes a soft-close seat, installation kit, and standard 12-inch rough-in. A two-year warranty is also listed. Compared with the MAXSA, this model is more clearly aimed at shoppers seeking an elevated seat; compared with the 19-inch Los Flexi, it is the less extreme height option.
Pros:
- Elongated bowl and raised height design.
- Includes a soft-close seat and installation kit.
- Standard 12-inch rough-in.
- Two-year warranty is listed.
Cons:
- The listing uses both 17-inch and 17.9-inch height descriptions, so confirm the measurement.
- A raised seat may not feel comfortable for every user.
Verdict: This is a reasonable option if you want an elevated elongated toilet, provided you confirm the actual seat height and rough-in before purchase.
DeerValley ADA Elongated Toilet: Best for a Clearly Stated Seat Height
The DeerValley is a two-piece elongated toilet with a listed floor-to-seat height of 17 13/16 inches and a standard 12-inch rough-in. That specific measurement is useful when comparing it with your current toilet or checking whether the seat height suits the people who will use it. The product details describe a 1.28 GPF power flush and a 360-degree jet intended to wash around the bowl.
It also has a quiet-close seat and a glazed porcelain finish. The main practical issue is availability: the supplied listing data marks this model as unavailable, so check its current listing status before planning a purchase. Its one-year limited warranty is described as covering the toilet, flushing mechanism, and soft-closing seat lid.
Pros:
- Floor-to-seat height is stated as 17 13/16 inches.
- Elongated bowl and 12-inch rough-in.
- 1.28 GPF power flush.
- Quiet-close seat and a listed one-year limited warranty.
Cons:
- The supplied listing data marks the product as unavailable.
- Confirm availability and installation details before choosing it.
Verdict: The DeerValley stands out for its specific seat-height measurement, but it is only a practical pick if it is available when you shop.
Los Flexi 19-Inch Extra-Tall Toilet: Best for Maximum Seat Height
This Los Flexi is the tallest option in this group, with a stated 19-inch height, an elongated bowl, and a two-piece design. It is aimed at people who find a standard toilet seat too low, including some seniors and people with mobility limits. A taller toilet is not automatically more comfortable for everyone, so compare the stated height with your needs and, if possible, a seat height that already feels comfortable.
The listed flush uses a 360-degree siphonic jet and a 3-inch flush valve, with a stated rate of 1.28 GPF. It includes a soft-close seat, wax ring, hardware, and a standard 12-inch rough-in. The product details also list a two-year warranty. Before ordering, confirm what the 19-inch measurement refers to, since the listing does not clarify whether it is the bowl height or seat height.
Pros:
- Stated 19-inch height for shoppers seeking an extra-tall toilet.
- 1.28 GPF siphonic jet flush.
- Includes a soft-close seat, wax ring, and installation hardware.
- Standard 12-inch rough-in and a listed two-year warranty.
Cons:
- The height description does not specify whether it is measured to the bowl or seat.
- Its extra-tall design may not suit every user.
Verdict: Choose this model if you specifically want an extra-tall toilet, but verify the measured seat height and make sure it suits everyone in your household.
How to Choose an Elongated Comfort Height Toilet
Measure the Rough-In
The rough-in is the distance from the finished wall behind the toilet to the center of the floor drain or mounting bolts, depending on how you take the measurement. The products here include both 10-inch and 12-inch rough-in models. Measure your bathroom carefully and compare that measurement with the toilet specifications; a toilet with the wrong rough-in may not fit your existing plumbing layout.
Check the Actual Seat Height
“Comfort height” can mean different things across listings, so look for a clear measurement rather than relying only on a product name. Note whether the listed number measures the bowl, the seat, or the overall toilet. The DeerValley description gives a floor-to-seat measurement, while the two Los Flexi listings describe their heights differently. If accessibility is a requirement, verify the exact model and its measurements rather than assuming a product title alone confirms fit.
Choose an Elongated Bowl That Fits Your Space
An elongated bowl extends farther forward than a round bowl and can provide more sitting room. It also needs enough floor space. Measure from the wall to the front of your current toilet and check the required clearance around the bowl, door, and nearby fixtures. A compact bathroom may call for a careful comparison of the toilet’s full dimensions before you buy.
Compare Flush Rate and Flush Design
Several models here list a 1.28 gallons-per-flush rate. The descriptions also mention siphonic flushing, siphon jets, or power-flush designs. Consider the stated water use and flush system, but do not assume similar flush rates mean identical performance. Follow the manufacturer’s installation and maintenance instructions for the specific model you choose.
Review What Comes in the Box
Included parts vary. Some listings specify a soft-close seat, wax ring, and installation hardware, while others provide fewer details. Check the product’s current specifications to see what you may need to buy separately. Also confirm whether you are comfortable with a two-piece toilet installation or would rather have a plumber handle the work.
Consider Who Will Use the Toilet
A raised seat can make sitting down and standing up easier for some people, while an extra-tall model may feel too high to others. Think about the needs of everyone in the household, including children and anyone with mobility concerns. If the toilet is meant to meet a specific accessibility need, confirm the measurements and applicable requirements with a qualified professional.
Check the Warranty and Current Availability
Warranty terms differ among these products, and one listing is marked unavailable in the supplied product information. Check the current product details for availability, warranty coverage, and return terms before you make a decision. Keep the order and installation information in case you need support later.
Frequently Asked Questions
What does comfort height mean for a toilet?
It generally refers to a toilet with a higher seat than a standard-height model, which may make sitting down and standing up easier for some people. Since product listings may use different measurements, check the actual floor-to-seat height before buying.
Is an elongated toilet more comfortable than a round one?
An elongated bowl provides more front-to-back room than a traditional round bowl. Some people prefer that shape, but it takes up more space and personal comfort varies.
How do I know whether I need a 10-inch or 12-inch rough-in?
Measure your existing toilet’s rough-in and compare it with the replacement model’s specifications. The Kohler Highline listed here is designed for a 10-inch rough-in, while the other products specify a standard 12-inch rough-in.
Is a 1.28 GPF toilet water-saving?
A 1.28 GPF toilet uses 1.28 gallons per flush according to its listed specification. Actual water use depends on how often it is flushed and on the model’s performance in your bathroom.
Does a soft-close seat come with every toilet in this comparison?
The supplied details explicitly list a soft-close seat for the MAXSA, both Los Flexi models, and the DeerValley. The Kohler details provided do not specify an included seat, so check the current listing before ordering.
Can I install a two-piece toilet myself?
Some homeowners may be comfortable with the work, especially when the rough-in matches and the needed parts are included. Installation still requires careful sealing and connections. If you are unsure about your plumbing or local requirements, consider using a qualified installer.
Final Recommendation
For an elevated seat with a clearly stated measurement, the DeerValley is worth considering if it is available, while the 17-inch Los Flexi offers another raised-seat option with an included installation kit. If you need an extra-tall toilet, compare the Los Flexi 19-inch model’s height carefully before buying. The Kohler Highline is the most relevant choice for a 10-inch rough-in, and the MAXSA offers several listed configurations—but its 15-inch version may not meet a comfort-height preference. In every case, verify the rough-in, seat-height measurement, and selected configuration before you order.
