Measure Before You Buy
Toilet seats come in two standard shapes. Measuring incorrectly is the only way to get this wrong.
Measure from hinge bolts to front of bowl
Use a tape measure from the center of the hinge bolts at the back of the bowl to the outside front edge. Round toilets measure about 16.5 inches; elongated toilets measure about 18.5 inches.
Check every toilet separately
Many homes mix shapes—an elongated toilet in the primary bathroom and a round one in the powder room are common. Don't assume they all match.
Confirm bolt spacing
Standard bolt spacing is 5.5 inches between hinge holes. Almost every standard seat fits this. If your toilet is non-standard (some high-end or European models), you may need to match a specific brand.
Choose Features: Soft-Close and Quick-Release
The extra $8–$15 for premium features pays back immediately in daily comfort.
- Soft-close hinges: The seat and lid lower slowly and quietly, preventing slamming. Saves the seat from breakage, your fingers from pinches, and nighttime noise.
- Quick-release: A button or latch lets you remove the entire seat for deep cleaning under the hinges. The hinge area is where bathrooms get grossest; quick-release makes it trivial to clean.
- Plastic versus molded wood: Plastic seats ($15–$25) are lighter and softer; molded wood seats ($25–$45) are heavier, more durable, and feel more substantial. Both last 10+ years with normal use.
- Bidet attachment upgrade: If you want a bidet, replace the seat with a bidet toilet seat ($40–$300). Installation is almost identical to a standard seat. Now is the cheapest time to upgrade.
Install in 10 Minutes
Bring a Phillips screwdriver and an adjustable wrench. That's it.
Remove the old seat
Pop open the hinge caps at the back of the seat, loosen the nuts beneath the bowl (usually plastic wing nuts), and lift the seat off. Dispose of or recycle the old seat.
Clean the rim area
This is the only moment the rim is fully accessible. Spray with a disinfecting cleaner and scrub around and into the hinge bolt holes. It will never be easier.
Install the new seat
Align the hinge bolts through the mounting holes, tighten the nuts underneath until snug (do not over-tighten and crack the porcelain), and close the hinge covers. The seat should be snug with no side-to-side movement.
Pro Tips
- •Do not over-tighten: Plastic nuts strip easily and over-torquing can crack a porcelain bowl. Snug is enough—the seat should not rock side to side, but you shouldn't strain against the nut.
- •Buy all your seats at once: Consistent hardware and color across bathrooms looks intentional. A trip-saving bulk purchase also means you have a matching spare if one breaks.
- •Save the packaging for 30 days: Soft-close mechanisms occasionally have defects. Manufacturers will replace them if you have the receipt and original packaging within their return window.
- •Consider a comfort-height upgrade: If the entire toilet is aging, now is the time to upgrade to a comfort-height (17-inch seat) unit for $150–$300. The seat replacement happens in the same afternoon.
Frequently Asked Questions
How do I know if my toilet is round or elongated?
Measure from the center of the hinge bolts (at the back of the bowl) to the outside front edge. Round toilets measure approximately 16.5 inches; elongated toilets measure approximately 18.5 inches. Always measure each toilet in the home—many houses mix sizes, especially between main bathrooms and powder rooms. If you are between sizes or buying multiple, elongated is slightly more comfortable and generally more common in modern homes.
Are soft-close toilet seats worth it?
Yes, for $8–$15 more per seat, soft-close is an immediate quality-of-life improvement. No more slamming at night, no more broken seats from kids, and dramatically less pinched fingers. Most soft-close seats also include quick-release hinges that let you detach the seat for deep cleaning in seconds. Soft-close mechanisms can wear out after 5–10 years, but at $30–$50 total you are still ahead of the savings over that time.
Do I really need to replace toilet seats before moving in?
It is one of the cheapest and most sanitary upgrades a new homeowner can make. For $15–$40 per seat and 10 minutes per toilet, you get a fresh, personal touch on one of the most used fixtures in the home. Toilet seats are considered a personal hygiene item—even professionally cleaned, inheriting a used one is understandably off-putting. Unlike deep cleaning that requires elbow grease, this is so quick and cheap there's no reason to skip it.
