Selecting the right toilet seat can improve your bathroom’s comfort and design. From basic models to high-tech options, there’s a variety of toilet seats available to suit every need and preference. This Old House plumbing and heating expert, Richard Trethewey, explores various toilet seat options and demonstrates the installation process in the video.
Understanding Toilet Seat Sizes
Before purchasing a new toilet seat, determine the correct size seat for your toilet. Toilet seats come in two standard sizes, the first being round seats, which typically measure 16 inches in length. The second option is an elongated seat measuring 18 inches in length.
To determine which size you need, measure the length of your current toilet bowl from the mounting holes at the back to the front edge. This will help you choose between a round or elongated seat. Choosing the right size will make a difference in comfort, fit, and functionality.
Pro Tip: Richard Trethewey, TOH plumbing and heating expert, notes that while plumbing has few standards, toilet seats are refreshingly simple: “In plumbing, there’s not many standards, but in toilet seats, there are a few. It’s either a round front, which is about 16 inches front to back, or elongated, and that’s another two inches deeper. You gotta get the right size based on which one you have.”
Measuring for the Perfect Fit
The right measurements guarantee a proper fit and prevent wiggle room, which can make the seat unstable. To select the right toilet seat, follow these steps:
- Measure the length of the toilet bowl from the mounting holes to the front edge.
- Measure the width of the toilet bowl at its widest point.
- Note the shape of your toilet bowl (round or elongated).
- Measure the distance between the mounting hole centers (typically 5.5 inches).
Types of Toilet Seats
Toilet seats come in different materials, styles, and features for your needs and preferences.
Standard Plastic Seats
Plastic seats are affordable, durable, and easy to clean. They come in a wide range of colors and are resistant to staining and chipping, making them a practical choice for homeowners.
Wooden Seats
Wooden toilet seats offer a classic, warm look and can be more comfortable in colder climates. However, they may require more maintenance and upkeep compared to plastic seats.
Padded Seats
Padded seats provide extra comfort and are often preferred by those with mobility issues or sensitive skin. They typically have a vinyl cover over a foam cushion. These seats are good for older people or individuals recovering from surgery.
Specialty Seats
There are many specialty toilet seats designed for specific needs. Bidet seats are high-tech options for washing and drying functions for better hygiene. Raised seats are helpful for elderly or mobility-impaired users as they add height to the toilet. Child training seats have a built-in smaller seat for potty training toddlers.
Installing a New Toilet Seat
Installing a new toilet seat is a straightforward process that most homeowners can handle. Here’s a step-by-step guide:
- Remove the old toilet seat by unscrewing the bolts at the back of the seat.
- Clean the toilet bowl surface where the new seat will be installed.
- Position the new seat over the toilet bowl, aligning the holes.
- Insert the new bolts through the holes and secure them with nuts from underneath.
- Tighten the bolts using a screwdriver, being careful not to overtighten and crack the porcelain.
- Check that the seat is level and adjust if necessary.
If you encounter difficulty removing the old seat due to corroded bolts, Trethewey suggests using a hacksaw to carefully cut through the bolts. Place a putty knife under the saw to protect the porcelain from scratches or chips.
Pro Tip: Richard Trethewey, TOH plumbing and heating expert, notes that modern toilet seats have simplified installation: “Nowadays you buy a new toilet seat, they’ve got it so that you can put it right into place.” The bolt spacing is always standardized at 5.5 inches center to center, so you only need to know whether your bowl is round (about 16 inches front to back) or elongated (about 18 inches).
If the old seat has brass bolts — common on seats that have been in place for decades — corrosion from moisture and urine can seize them tight. Richard Trethewey advises starting with a deep socket from underneath to try working the nut free. When that fails, a hacksaw is the right tool, but never a reciprocating saw. As Trethewey explains: “Using a Sawzall isn’t one of them because it’s likely to scratch the porcelain.” To protect the bowl, place a flat putty knife or a strip of tape under the blade as you cut through the soft brass. Many modern replacement seats now come with nylon bolts and washers precisely because they don’t rust, eliminating this problem for the next owner.
Troubleshooting Installation Issues
Sometimes, installing a new toilet seat might not go as smoothly as planned. For stubborn and corroded bolts, apply a penetrating oil to loosen them. If you notice misaligned holes, check and recheck your measurements to make sure the holes align correctly. If you’re noticing seat movement, make sure the bolts are tight but not too tight, as this can damage the toilet.
Pro Tip: When tightening seat bolts — or any bolts on porcelain — remember that overtightening is a common and costly mistake. As TOH’s Richard Trethewey has warned, “You tighten it too much and that’s gonna crack in a heartbeat.” Snug the bolts just enough to eliminate movement, then stop. Porcelain doesn’t flex, so any extra force goes straight into cracking the fixture.
New Toilet Seat: Features To Consider
When choosing a new toilet seat, consider these features for better comfort and functionality:
- Slow-close mechanism: Prevents slamming and noise, making your bathroom quieter.
- Quick-release hinges: Allows for easy removal and cleaning to simplify your maintenance routines.
- Antimicrobial coating: Prevents the growth of bacteria and mold for better hygiene.
- Heated seats: Provide warmth in colder climates, adding extra comfort.
- Night lights: Offer illumination for nighttime use, making it easier to navigate the bathroom without turning on bright lights.
Additional Considerations
Some seats have eco-friendly materials to reduce your environmental footprint. Splash guards can be very useful in homes with young children, preventing messes and making cleanup much easier. Some seats also have universal compatibility options for most toilet brands and models. Weighing these features can help you decide on the best toilet seat.

Toilet Seats: Maintenance and Cleaning
Proper maintenance can extend the life of your toilet seat and keep it hygienic. Clean your toilet seat regularly with mild soap and water, avoiding harsh chemicals that can damage the seat materials. Tighten loose bolts periodically to prevent wobbling and replace worn or damaged seats to maintain a hygienic space. For wooden seats, apply a coat of wood polish as needed to protect the finish and prevent cracking.
Cleaning Techniques
Cleaning practices can prolong the life of your toilet seat. Always use non-abrasive cleaners to prevent scratching or damage to the surface. Use soft cloths or sponges to clean your seat to avoid damaging the finish.
With regular inspections, you should check for cracks, wear, and loose parts so your seat can stay sanitary and in good condition. Taking the time to choose, install, and maintain the right toilet seat pays off in the long run when considering comfort and style in your bathroom.
