Comfort Height Toilet Installation Service
Call Now (855) 557-9600
Comfort height toilet installation replaces standard 14-to-15-inch seats with ADA-compliant 17-to-19-inch models that reduce the effort required to sit and stand, eliminating daily strain on compromised knee, hip, or back joints. Bonded Plumbworks’ licensed plumbers match the replacement to your existing 12-inch rough-in, then install TOTO Drake II, Kohler Highline, or American Standard Champion ADA-height models with elongated bowls and slow-close seats. Comfort height toilet installation is the most frequently requested aging-in-place bathroom modification.
A comfort height toilet, also called a right height or ADA-compliant toilet, has a bowl rim height of 15 to 17 inches measured from the finished floor, resulting in a seated height of 17 to 19 inches with the seat installed. This matches standard chair height and reduces the knee bend required to sit and stand compared to a standard toilet at 14 to 15 inches. — Bonded Plumbworks
What Is Comfort Height Toilet Installation
Comfort height toilet installation is the removal of a standard-height toilet and replacement with a taller model that meets ADA Standards for Accessible Design. The process includes disconnecting and removing the old toilet, inspecting the closet flange and floor condition, installing a new wax ring or wax-free seal, setting and leveling the new toilet, connecting the water supply line, and testing flush performance.
The two-inch height difference between a standard toilet (14-15 inches) and a comfort height toilet (17-19 inches) may seem minor, but it reduces the required knee flexion from approximately 90 degrees to approximately 110 degrees. For someone with arthritic knees or recovering from joint replacement surgery, this difference eliminates the need for grab bar assistance in many cases.
The ADA Standards for Accessible Design specify a toilet seat height of 17 to 19 inches above the finished floor for accessible restrooms. Comfort height residential toilets meet this range without requiring a raised toilet seat attachment, which can shift during use and create a secondary fall risk. — Bonded Plumbworks, serving since 2006
When to Schedule Comfort Height Toilet Installation
Comfort height toilet installation suits households where rising from a standard toilet requires assistance, post-surgery recovery is expected, and aging-in-place modifications are already underway.
- Standing up from a standard toilet requires holding onto a grab bar, counter, or wall
- You or a household member has undergone or is scheduled for hip or knee replacement surgery
- A physician or occupational therapist has recommended bathroom modifications
- You are planning aging-in-place upgrades throughout the home
- Current toilet uses a bolt-on raised seat that feels unstable
- Remodeling a bathroom and want to upgrade to current accessibility standards
- A taller household member finds standard-height toilets uncomfortable
Comfort height toilet installation pairs well with grab bar installation on the adjacent wall, creating a complete accessible toilet station that allows safe, independent use.
How It Works
Step 1: Toilet Selection. We help you select a comfort height toilet that fits your bathroom’s rough-in dimension (the distance from the wall to the center of the closet flange, typically 12 inches). We discuss bowl shape (round vs. Elongated), flush technology (gravity, pressure-assist, or dual-flush), and features like a slow-close seat.
Step 2: Old Toilet Removal. We shut off the water supply, flush and sponge the remaining water, disconnect the supply line, remove the closet anchor bolts, and lift the toilet off the closet flange. New brass closet anchor bolts are installed with every comfort height toilet installation because corroded original bolts can snap during tightening or fail under the toilet’s weight. We inspect the closet flange for damage, corrosion, or improper height relative to the finished floor.
Step 3: Flange Inspection and Repair. If the closet flange is cracked, corroded, or sits below the finished floor, we repair or replace it before installing the new toilet. A flange that sits below floor level is the most common cause of toilet base leaks and must be corrected with a flange extender or full replacement. Comfort Height Toilet Installation inspection gives you a live view of the problem before any work starts. You review the findings and approve the quote before any repair begins.
Step 4: Installation. We set a new wax ring or wax-free gasket, position the comfort height toilet over the flange bolts, press it to create a seal, level it using shims if the floor is uneven, tighten the closet bolts evenly, and connect the water supply with a new braided stainless steel supply line.
Step 5: Testing. We fill the tank, perform multiple test flushes, check for leaks at the base, supply connection, and tank-to-bowl gasket, and verify that the toilet sits stable and level. Fill valve replacement may be recommended during comfort height toilet installation when the existing fill valve is incompatible with the new toilet’s tank geometry or water level requirements. Flush valve replacement ensures the internal flush mechanism matches the new comfort height toilet installation’s specified flush volume and performance rating. We caulk the base per state building code requirements.
The State building codes require caulking around the base of a toilet to prevent moisture intrusion beneath the fixture. Bonded Plumbworks leaves a small gap at the rear of the caulk line as a leak indicator — if the wax seal ever fails, water will appear at the gap rather than being trapped invisibly under the toilet. — Bonded Plumbworks
Benefits vs. Alternatives
| Option | Seat Height | Stability | Aesthetics | Cost |
|---|---|---|---|---|
| Comfort Height Toilet | 17-19 inches | Excellent | Integrated design | $$ |
| Raised Toilet Seat | 19-21 inches | Moderate (can shift) | Visible attachment | $ |
| Toilet Seat Riser with Arms | 20-22 inches | Good (with arms) | Medical appearance | $ |
| Wall-Hung Toilet (adjustable) | Custom | Excellent | Modern | $$$ |
| Standard Toilet (no change) | 14-15 inches | Standard | Standard | — |
A comfort height toilet is a permanent, integrated solution. Bolt-on raised seats and risers are temporary alternatives that can shift during use, require cleaning around edges, and present an institutional appearance that most homeowners prefer to avoid.

FAQ
What is the difference between comfort height and standard height toilets? A standard toilet has a bowl rim height of 14 to 15 inches, resulting in a seated height of about 15.5 inches with the seat. A comfort height toilet has a rim height of 15 to 17 inches, resulting in a seated height of 17 to 19 inches. The taller height reduces strain on knees and hips when sitting and standing.
Are comfort height toilets good for short people? Comfort height toilets may be too tall for individuals under five feet two inches, as their feet may not rest flat on the floor. In these cases, a standard-height toilet with a grab bar is often a better accessibility solution. We assess individual needs during the in-home consultation.
How much does comfort height toilet installation cost? Comfort Height Toilet Installation typically costs $150 to $1,400 for most residential jobs. The final price depends on the scope of work, materials required, and site conditions. Bonded Plumbworks provides a written estimate before starting any comfort height toilet installation work, so you know the exact cost upfront. Call (855) 557-9600 for a same-day quote.
Can I keep my existing toilet seat? In most cases, no. Toilet seats are not universal between manufacturers and bowl shapes. We include a new seat with every comfort height toilet installation, and we offer soft-close, open-front, and bidet-compatible seat options. Bidet seat compatibility should be verified before selecting a comfort height toilet installation model, because some elongated bowl shapes and tank clearances do not accommodate the electronic bidet seats that require a GFCI outlet within three feet of the toilet. A GFCI outlet near the toilet is increasingly specified during comfort height toilet installation to support future bidet seat addition without requiring drywall surgery for electrical work later.
