Replace Your Toilet Seat
A cracked, stained, or wobbly toilet seat makes even a clean bathroom feel dingy. Modern soft-close seats prevent slamming and look much nicer. This is a 15-minute fix.

Before You Buy: Measure Your Toilet
Toilets come in two shapes, and the seat must match. Getting this wrong means a return trip to the store.
Round
Circular front. Measures about 16.5 inches from mounting holes to front of bowl. Common in older homes and small bathrooms.
Elongated
Oval/oblong front. Measures about 18.5 inches from mounting holes to front of bowl. More common in newer construction. More comfortable for most adults.
Pro tip: Measure from the center of the mounting bolt holes to the very front of the bowl. Round ≈ 16.5", Elongated ≈ 18.5".
Seat Options
Soft-Close / Slow-Close
$30-60Hinges lower the seat and lid slowly—no more slamming. Worth every penny, especially in homes with kids. Most popular upgrade choice.
Quick-Release
$35-70Push a button and the entire seat pops off for easy cleaning behind and around the hinges. Often combined with soft-close. Highly recommended.
Basic / Standard
$15-30Simple plastic or wood seat. Gets the job done but lacks modern conveniences. Fine for rentals or tight budgets.
Bidet Seat
$50-500+Adds water spray for cleaning. Basic models are affordable; heated seats with dryers cost more. Requires nearby outlet for powered models. Different installation—see our bidet guide.
Step-by-Step
Locate the Mounting Bolts
Look at the back of the seat where it connects to the toilet. You'll see two bolt covers (plastic caps) or exposed bolt heads. Flip up the caps if present.
Remove Old Seat
Most seats use plastic bolts—turn counterclockwise with a screwdriver or by hand. For metal bolts, you may need pliers or a wrench to hold the nut underneath while turning the bolt from above. Corroded metal bolts may need penetrating oil or cutting.
Clean the Mounting Area
With the old seat off, clean around the bolt holes and the entire top of the toilet bowl. This area collects grime that's normally hidden.
Position New Seat
Align the new seat over the bowl so the bolt holes line up. Insert the bolts through the seat hinges and down through the toilet's mounting holes.
Tighten & Adjust
Hand-tighten the nuts from below (or tighten the bolts from above, depending on design). Don't overtighten—you can crack the porcelain. The seat should be snug but not straining. Test that it's centered and doesn't shift.
Pro Tips
- ✓Match your toilet color. Most toilets are "white," but there are variations (bone, biscuit, cotton white). Bring a photo to the store.
- ✓Check bolt hole spacing. Standard is 5.5" center-to-center, but some toilets vary. Measure yours to be safe.
- ✓Consider the lid shape. If you have items on the tank lid, make sure the seat lid won't knock them off when fully open.
- ✓Stuck bolts? Spray with WD-40 or PB Blaster and wait 15 minutes. For severely corroded metal bolts, a hacksaw blade can cut through them.
