Choosing a comfort-height toilet can make sitting down and standing up easier, but “back-to-wall” is an important fit detail: it usually describes a toilet designed to sit close against the wall, often with a concealed cistern. The products below are described as floor-mounted toilets, and the supplied specifications do not confirm that any is a true back-to-wall model. They are worth comparing for their taller seating, but check the toilet’s layout, rough-in, and tank arrangement against your bathroom before ordering.
Our picks range from extra-tall models to standard comfort-height designs. Compare the stated seat or bowl height, flush options, included parts, and installation dimensions to find the best match for your needs.

Our Picks: Best Comfort Height Back To Wall Toilet reviews
1. Los Flexi 21-Inch Tall Toilet: Best for Extra-High Seating
The Los Flexi is a two-piece toilet designed around a 21-inch height, an especially tall option for people who find standard toilets difficult to use. Its elongated bowl provides more room than a round bowl, and the included soft-close seat avoids the need to buy one separately.
The toilet uses a 1.28 GPF flush and is made from ceramic, with a polypropylene seat. The listed dimensions are 29.13 inches deep, 15.75 inches wide, and 36.22 inches high. The package includes the toilet, seat, wax ring, bolt kit, and seat installation kit, which gives you several key parts for setup.
Its height may suit taller adults, seniors, or people who want less distance to lower themselves onto a seat. However, extra height is not automatically more comfortable for everyone; shorter users may find it harder to sit with their feet comfortably supported. Also, the product information does not confirm a back-to-wall configuration, so check the tank and wall clearance for your bathroom.
Pros:
- 21-inch design for users seeking a notably tall toilet
- Elongated bowl and soft-close seat included
- 1.28 GPF flush specification
- Wax ring and bolt kit are included
Cons:
- Its extra height may not suit shorter users
- Back-to-wall compatibility is not confirmed in the supplied details
Verdict: Choose the Los Flexi if extra-tall seating is your priority and its dimensions and tank layout work in your bathroom.
2. HOROW 19-Inch Tall Toilet: Best for Adjustable Flush Options
HOROW states that this model measures 19 inches from the floor to the seat, making its height specification more precise than products that only use a general “comfort height” label. It is a two-piece floor-mounted toilet with a round seat, a soft-close lid, and a 12-inch rough-in.
The dual-flush system offers 1.1 and 1.6 GPF options. The product description also states an average flush use of 1.28 gallons. A jet siphon flush is designed to move waste through the bowl, while the fully skirted drain design can make the toilet’s exterior easier to wipe down.
This model is a practical option if you want a taller seat without going to the 21-inch height of the Los Flexi or Simple Project. Its stated 12-inch rough-in is useful when replacing a toilet, but measure your existing rough-in rather than assuming it will fit. The supplied details do not describe this as a back-to-wall toilet, so verify the installation style as well.
Pros:
- Clear 19-inch floor-to-seat measurement
- Dual-flush choices of 1.1 and 1.6 GPF
- Soft-close seat is included
- 12-inch rough-in is stated in the product details
Cons:
- May not be tall enough for shoppers seeking a 21-inch seat
- Confirm the rough-in and back-to-wall layout before purchase
Verdict: Consider the HOROW if you want a clearly stated 19-inch seat height and the flexibility of a dual-flush system.
3. Kohler Cimarron Comfort Height Toilet: Best for a Familiar Brand and Elongated Bowl
The Kohler Cimarron is a two-piece toilet with an elongated bowl and the brand’s Comfort Height feature. The listing describes its seating as chair height, a design intended to make sitting and standing easier for many adults. It uses a 1.28 GPF flush and has a left-hand polished chrome trip lever.
This pick is less tall than the 19- and 21-inch models in this list, based on the information provided. That can be an advantage if you want a more moderate raised seat rather than an extra-tall toilet. The listed dimensions are 27.5 inches deep, 14.5 inches wide, and 31 inches high. Its listed color is Ice Gray, so confirm the finish selection if you need white.
A key cost and setup consideration is that the toilet seat is not included. You will need to choose a compatible seat separately. The supplied product information identifies it as floor-mounted but does not confirm a true back-to-wall design, so check the layout before treating it as a replacement for a wall-hugging or concealed-cistern toilet.
Pros:
- Elongated bowl and Comfort Height seating
- 1.28 GPF flush specification
- Two-piece design with a left-hand trip lever
- Listed dimensions may suit bathrooms where a taller 21-inch toilet is unnecessary
Cons:
- Toilet seat is not included
- Listed color is Ice Gray, not white
Verdict: The Cimarron is a sensible choice for a moderate comfort-height upgrade if you are comfortable sourcing a separate seat and the Ice Gray finish suits your bathroom.
4. Simple Project 21-Inch Tall Toilet: Best for a Skirted Design
Simple Project describes this model as a 21-inch tall toilet with an elongated bowl and a skirted design. The listed dimensions are 28.35 inches deep, 14.3 inches wide, and 36 inches high. Its vitreous china surface and skirted exterior are intended to make routine wiping easier than cleaning around an exposed trapway.
The description also names a 360-degree jet siphon flushing system and a soft-close seat. Unlike the Los Flexi, the supplied details do not state a GPF figure, so shoppers who are comparing water use should confirm that information before buying. The product is shipped in two packages, with the seat and tank sent separately. Plan for both deliveries before scheduling installation.
The tall bowl may be helpful for people who prefer a high sitting position, but it may not suit every household member. The raised base and skirted shape also make it important to check the actual footprint and plumbing connections. Although the title mentions an ADA elongated toilet seat, the supplied information does not establish certification for the full toilet; do not treat that wording alone as proof that the complete product meets a particular accessibility standard.
Pros:
- 21-inch bowl height is stated
- Elongated bowl and soft-close seat
- Skirted design can simplify exterior cleaning
- Vitreous china construction
Cons:
- Tank and seat arrive in separate packages
- GPF information is not provided in the supplied details
Verdict: Choose this model if you want a 21-inch toilet with a skirted exterior, and confirm delivery, flush specifications, and bathroom fit before ordering.
5. Kohler Highline 10-Inch Rough-In Toilet: Best for a 10-Inch Rough-In
The Kohler Highline is a two-piece elongated toilet with Comfort Height seating and a 1.28 GPF flush. Its standout feature is the 10-inch rough-in, which makes it a candidate for bathrooms where that measurement is required. The product is made from vitreous china and has a white finish.
The elongated bowl offers more front-to-back room than a traditional round bowl, according to the product details. Listed dimensions are 29.5 inches deep, 18 inches wide, and 31.25 inches high. The package is described as “product only,” so do not assume that every installation part or a seat is included; confirm what comes with the version you select.
This model can make sense when your plumbing layout calls for a 10-inch rough-in and you prefer a familiar two-piece design. The listing does not provide a precise seat height, so it is difficult to compare its actual sitting height directly with the 19- and 21-inch models. It is also not identified as a true back-to-wall toilet in the supplied information.
Pros:
- 10-inch rough-in is specified
- Elongated bowl and Comfort Height design
- 1.28 GPF flush specification
- White vitreous china construction
Cons:
- Exact seat height is not stated
- Listed as product only, so confirm whether a seat and installation parts are included
Verdict: The Highline is worth considering when you need a 10-inch rough-in, but verify the included components and seating height before choosing it over a taller option.
How to Choose a Comfort-Height Back-to-Wall Toilet
Confirm what “back-to-wall” means for your bathroom
Back-to-wall can refer to a toilet pan that sits close to the wall, but bathroom listings may use the phrase differently. Some designs pair a close-fitting pan with a concealed cistern, while the products in this comparison are described as floor-mounted, two-piece toilets or do not provide enough detail to confirm their layout. Compare product diagrams and installation instructions with your existing setup before ordering. If you need a concealed-cistern or true back-to-wall model, confirm that exact design with the seller or manufacturer.
Measure seat height and consider who will use the toilet
“Comfort height” does not always provide an exact measurement. The HOROW listing specifies 19 inches from the floor to the seat, while the Los Flexi and Simple Project listings describe 21-inch designs. A higher seat can make sitting and standing easier for some people, but it can feel too tall for others. Think about the needs of everyone in the household and, when possible, compare the product’s measurement method with how your current toilet feels.
Check rough-in and overall dimensions
Rough-in is the distance from the finished wall behind the toilet to the center of the floor drain. Measure it before shopping and compare it with the model’s installation requirements. HOROW lists a 12-inch rough-in, while the Kohler Highline is made for a 10-inch rough-in. Also check depth, width, total height, tank clearance, and door or cabinet swing so the toilet fits the available space.
Choose the bowl shape that fits your space and comfort needs
An elongated bowl generally projects farther into the room than a round bowl, so check its depth against the space in front of the toilet. Several picks here have elongated bowls, but their listed dimensions vary. The available information identifies the HOROW seat as round, so compare the complete bowl and seat dimensions if you are considering it for a tight bathroom.
Compare flush options and water-use information
Look for the stated gallons per flush (GPF) and how the flush controls work. The Los Flexi and both Kohler picks list a 1.28 GPF flush. HOROW offers 1.1 and 1.6 GPF options. The Simple Project description names a jet siphon system but does not give a GPF figure in the supplied details. If water use is a deciding factor, verify the exact specifications for the model you plan to buy.
Check what is included and how it ships
A toilet package may or may not include a seat, wax ring, bolts, and other installation parts. Los Flexi lists a seat and installation kit, HOROW lists a soft-close seat, and the Kohler Cimarron listing says the seat is not included. Simple Project says its seat and tank ship separately. Confirm the included parts and delivery arrangement so you can plan installation without unexpected delays.
Think about cleaning and everyday maintenance
A skirted exterior can reduce the exposed curves around a toilet’s trapway, which may make the outside easier to wipe. Simple Project and HOROW both describe skirted designs. Consider the seat material and whether it is included, too. A soft-close seat can lower quietly, but it does not change the toilet’s bowl height or confirm that the overall product matches a back-to-wall installation.
Frequently Asked Questions
Are these all true back-to-wall toilets?
No. The supplied product details describe these options as floor-mounted or two-piece toilets, but they do not confirm a true back-to-wall pan and concealed-cistern setup. If that layout is essential, verify it directly before buying.
What is the difference between comfort height and an extra-tall toilet?
Comfort height is a general description for a toilet designed with higher seating than many standard models. “Extra tall” models may state a specific height, such as the 19-inch HOROW or the 21-inch designs in this list. Always check whether the measurement is to the bowl, rim, or top of the seat.
Which toilet in this list has the highest stated height?
The Los Flexi and Simple Project are both described as 21-inch models. The Los Flexi description calls it a 21-inch toilet design, while Simple Project specifically states a 21-inch bowl height. Check each product’s measurement details before comparing it with a seat-height measurement from another model.
Is a 21-inch toilet right for every senior?
No. A higher toilet can make sitting and standing easier for some people, but it may feel too tall for others, especially if their feet do not rest comfortably on the floor. Choose based on the user’s mobility, height, and comfort rather than age alone.
Which models list a dual-flush system?
The HOROW lists two flush choices: 1.1 GPF and 1.6 GPF. The other product details provided do not list a dual-flush option.
Do all of these toilets include a seat?
No. HOROW and Los Flexi list a seat, and Simple Project describes a soft-close seat that ships separately from the tank. The Kohler Cimarron listing says its seat is not included. For the Kohler Highline, the supplied information lists the package as product only, so confirm the seat and installation parts before purchase.
What should I measure before replacing a toilet?
Measure the rough-in from the finished wall to the center of the floor drain, then check the available width and depth, tank clearance, and door or cabinet clearance. Confirm that the toilet’s seat height and installation style suit the people using it and your plumbing layout.
Final Recommendation
For the most specific extra-tall options, compare the Los Flexi and Simple Project 21-inch models, paying close attention to their measurement details and included parts. The HOROW is a strong option if you want a stated 19-inch floor-to-seat height and dual-flush controls. For a true back-to-wall installation, none of the supplied descriptions confirms that configuration, so verify the design before choosing any of these toilets.
