Five elongated toilet seats compared by fit, hinges, closing action, lift-off cleaning and each maker's documented warranty, with measuring notes.
Please note: Product availability and information are based on our research at time of writing and are subject to change. Always check Amazon for the latest details before purchasing. Our assessments are research-based: we compared each maker’s specification sheets, installation instructions, care guides and warranty documents, and the Amazon listings, and we have not installed these seats ourselves. Where a detail comes only from a listing, we say so.
A replacement toilet seat is a small job with a few details that decide whether it fits and how it behaves: the bowl shape, the bolt spacing, how the hinges mount, whether the lid closes quietly, and whether the seat lifts off for cleaning. This roundup covers five elongated seats, each chosen for a different combination of those details: a Quiet-Close plastic seat, an enameled-wood seat with lift-off hinges, a slow-close seat with non-slip bumpers, a 3-inch elevated seat, and a slow-close seat with a locking hinge and a lift-off ring. The comparison table starts with fit and function and says where each detail comes from. All five are white and elongated, and every statement about them below comes from the maker’s own documents or, where we say so, from the Amazon listing. If you are weighing wood against plastic first, our wood vs plastic toilet seats comparison covers that choice.

All five makers publish a specification sheet, and four publish installation instructions we could read; every seat here uses 5-1/2 in (140 mm) mounting-hole spacing per its maker and is sold as fitting most elongated toilets. Each maker’s written warranty for its seat is one year (Bemis says “a minimum of one year”); no seat here carries a maker-documented lifetime warranty, whatever a retailer page may say. Check the seller, offer condition and warranty eligibility before buying. Each link selects the white elongated version on a page that may also offer round or multi-pack options, so check the selection before you order.
✏️ Our Take
Confirm the bowl shape and bolt spacing first, then choose by function. If quiet closing matters most, the KOHLER Brevia, Delta Morgan and American Standard seats all document a slow or Quiet-Close action; if lifting the seat off for cleaning matters most, the Bemis, the KOHLER Hyten and the American Standard document a lift-off or Quick-Release hinge; if a higher seat is the need, the Hyten is the only elevated seat here. Read each maker’s warranty and care guide linked below: all five are one-year warranties with cleaning conditions, and the American Standard warranty is void for purchases from unauthorized sellers.
IN THIS GUIDE
Quiet-Close Plastic Seat
KOHLER’s specification sheet for the K-20110 (spec sheet) lists a Quiet-Close elongated lid and seat that “prevents slamming”, Grip-Tight bumpers that “hold seat firmly in place”, Quick-Attach hardware “for fast and secure installation”, color-matched plastic hinges and a fit for most elongated toilets; the material is plastic construction, and the sheet lists no applicable codes or standards. KOHLER’s nominal dimensions are 18-5/8 in (473 mm) overall, 18 in (457 mm) from the bolt holes to the front, 14-3/16 in (360 mm) wide, with 5-1/2 in (140 mm) mounting-hole spacing. KOHLER’s product page (KOHLER page) adds that it is engineered to fit most one- and two-piece elongated toilets. This link selects the white elongated version; the same Amazon page offers round-front and multi-pack options.
Two limits are worth knowing. The K-20110 is not a quick-release seat: KOHLER’s own comparison lists Quick-Release for the separate Brevia K-4774, not for this model, so the hinges stay on the bowl and cleaning behind them means working around the seat. And KOHLER’s written warranty (KOHLER Toilet and Seat Warranty) is a one-year limited warranty from the date of installation, covering defects in material and workmanship, with removal and installation costs excluded; KOHLER’s care guidance is mild soap and warm water, no abrasive, aerosol or chemical cleaners. The sheet says to install per KOHLER’s instructions and gives no tool list, so we do not call the installation tool-free. The Amazon listing notes that KOHLER does not accept returns of opened seats. This review does not cover installation.
KOHLER
Best for: Quiet-Close Plastic Seat
KOHLER's Brevia is a plastic elongated seat with a Quiet-Close lid and seat, Grip-Tight bumpers and Quick-Attach hardware, covered by KOHLER's one-year limited warranty.
Wood Seat, Lift-Off Hinges
The Bemis 1500EC is the one wood seat here. Bemis’s specification sheet (spec sheet) describes a residential enameled-wood elongated seat, closed front with cover, two ring bumpers, plastic hinges, non-corroding bolts and wing nuts, and the Easy-Clean & Change hinge that “removes for easy cleaning”; it is marked “Proudly Made in the USA”. Bemis’s product page (Bemis page) lists a 5.5 in bolt spread, 18.875 in depth, 14.125 in width, 2 in height and about 7.5 lb, a high-gloss finish that Bemis says resists chipping and scratching, and a fit for most manufacturers’ elongated toilets. There is no slow close on this model; Bemis sells slow-close wood seats separately. This link selects the white elongated version; a round version shares the page.
Bemis’s installation sheet (installation instructions) needs a screwdriver: the bolts drop through the hinge holes, the wing nuts turn on from below, the hinge unlocks, the seat snaps onto the bolts and the hinge locks again, which is the same action that lets the seat come off for cleaning. Bemis’s use and care guide (use and care guide) allows only mild soapy water and a soft cloth, and warns that bleach, pine or essential oils, chlorine, acids, disinfectants, aerosols, hard brushes and scouring powders “can rub away or corrode paint finishes on toilet seats”; Bemis gives no instruction to apply any finish or coating, so we give none. Bemis’s warranty card (Bemis limited warranty) guarantees seats against defects in material and workmanship “for a minimum of one year from date of purchase”, with enameled-wood seats for residential use only, and Bemis’s standard terms of sale give toilet seats a one-year warranty period with removal, labor and shipping costs excluded. Check the seller, offer condition and warranty eligibility before buying. This review does not cover installation.
Bemis
Best for: Wood Seat, Lift-Off Hinges
Bemis's 1500EC is an enameled molded-wood elongated seat with Easy-Clean & Change hinges that unlock so the seat lifts off, made in the USA per Bemis.
Slow-Close, NoSlip Bumpers
Delta’s specification sheet DSP-B-811901 (spec sheet), which covers the 811903, lists a Slow-Close lid and ring that “prevents slamming”, NoSlip bumpers that keep the seat from shifting, fast and secure installation, a universal fit on most elongated-front bowls with about 1/2 in of adjustability, and “solid construction with added weight for durability”; the standard specification is an elongated shape with 5-1/2 in (140 mm) mounting holes, the drawing shows 18-1/2 in (470 mm) by 14 in (356 mm) by 1-7/8 in (48 mm), and the sheet states compliance with IAPMO/ANSI Z124.5. Delta’s product page (Delta page) adds that the finish is resistant to staining, fading, chipping and peeling, that mounting hardware and instructions are included, and that the seat is not intended for commercial use. Delta’s sheet does not name the material; the Amazon listing lists plastic. This link selects the slow-close configuration; a standard-close configuration shares the page.
Delta’s installation sheet (installation sheet) shows a screwdriver and safety glasses: the bolt goes down through the hinge, the nut is tightened from under the bowl, and the caps close over the hardware. Delta claims no quick-release or lift-off hinge for this seat; a Delta support reply says the hinge caps pull back to reach the screws, and that a slow-close mechanism that stops damping means replacing the seat. Delta’s toilet seat warranty (Delta toilet seat warranty) covers the original consumer purchaser against defects in material and workmanship for one year from purchase, replacing a defective part or finish free of charge, with proof of purchase and no coverage for commercial use; a “lifetime” warranty appears on some retailer pages but not in Delta’s own documents. Delta’s care sheet says mild cleanser and warm water, no concentrated detergents, and not to force the seat closed. This review does not cover installation.
Delta
Best for: Slow-Close, NoSlip Bumpers
Delta's Morgan is an elongated slow-close seat with NoSlip bumpers, 18-1/2 x 14 in per Delta's spec sheet, with a one-year warranty.
3-Inch Elevated Seat
The Hyten is the only elevated seat here. KOHLER’s specification sheet for the K-25875 (spec sheet) lists a 3 in (76 mm) raised seating surface that “provides a more comfortable height for those with limited mobility”, a design that mimics a conventional seat with no separate riser, an elongated closed-front contoured seat, Grip-Tight installation hardware with “everything done from above the bowl”, Quick-Release functionality so the seat “can be removed easily from toilet for convenient cleaning”, Grip-Tight bumpers, a Quiet-Close lid and seat, and a fit for most elongated toilets; material is plastic construction, the standard is IAPMO/ANSI Z124.5, and KOHLER marks it “for residential use only”. KOHLER’s dimensions are 3-5/8 in (92 mm) overall height, 18-3/4 in (476 mm) long, 18-3/16 in (462 mm) bolt holes to front, 14-7/16 in (367 mm) wide, 5-1/2 in (140 mm) holes. This link selects white; the same page offers round and multi-pack options, and KOHLER lists six colours.
KOHLER’s installation reference guide (installation reference guide) says the seat “requires just a screwdriver”: anchors fold into the bolt holes, screws tighten from above, caps cover the hardware, and pushing the Quick-Release button lifts the seat off for cleaning. Two cautions: KOHLER makes no ADA claim for this seat anywhere we could find, and its wording is “limited mobility”, not accessibility compliance, so we make no such claim either; and a 3 in rise that helps one person can be awkward for a shorter user or a young child who shares the toilet. KOHLER’s warranty (KOHLER Toilet and Seat Warranty) is the same one-year limited warranty from installation as the Brevia. The Amazon listing notes that KOHLER does not accept returns of opened seats. For the difference between an elevated seat and a taller toilet, see the buying guide below. This review does not cover installation.
KOHLER
Best for: 3-Inch Elevated Seat
KOHLER's Hyten adds a 3 in raised seating surface for people with limited mobility, with Quiet-Close, Grip-Tight bumpers and a Quick-Release button, for residential use only per KOHLER.
Locking Hinge, Lift-Off Seat
American Standard’s specification sheet for the 5020A65G (spec sheet) describes a “Traditional Luxury Easy Lift-Off” elongated seat with slow close and EverClean: an Ever-Tite stabilizing hinge “to prevent the seat from shifting side to side”, a slow-close seat and lid, a removable seat with “No Tools Required”, a silver-based EverClean surface, universal bowl fit, and both top and bottom mounting; the nominal size is 18-9/16 in (472 mm) by 14-1/8 in (359 mm) by 2-1/4 in (58 mm) with 5-1/2 in (140 mm) holes. American Standard’s product page (American Standard page) lists durable polypropylene, quick-release hinges for cleaning, all mounting hardware included, and a one-year limited warranty. EverClean is American Standard’s claim about the seat surface, that its silver-based surface “permanently inhibits the growth of stain and odor causing bacteria, mold and mildew on the surface”; the same sheet states that the “EverClean surface does not protect against disease causing bacteria”, so it is a surface-care feature, not a health protection for the user, and we repeat it only as the maker’s claim with that caveat. This link selects the white elongated-front version; a round-front version shares the page.
The owner’s manual (owner’s manual) gives top-mount and bottom-mount steps, both using a screwdriver, and the lift-off is two buttons inside the hinges: “push both inside buttons to release seat and cover” and pull upward; care is mild soapy water, rinse and dry, with no detergents, disinfectants, aerosols or abrasive powders, and American Standard asks you to check the bolts “from time to time”. American Standard’s 2025 warranty for toilets and toilet seats (American Standard warranty) gives toilet seats one year from purchase, for the original purchaser, and is void if the product “was purchased from an unauthorized seller”, so retailer wording about a lifetime warranty does not apply to this seat. Check the seller, offer condition and warranty eligibility before buying. This review does not cover installation.
American Standard
Best for: Locking Hinge, Lift-Off Seat
American Standard's Traditional seat is a polypropylene elongated seat with slow close, an Ever-Tite locking hinge, two-button lift-off and an EverClean antimicrobial surface, with a one-year warranty.
All five seats here are elongated. Before ordering, measure your bowl from the centre of the seat bolt holes straight to the front rim: an elongated bowl measures close to 18-1/2 in and a round bowl close to 16-1/2 in, the commonly used sizing guidance, and the five makers’ bolt-to-front seat lengths run from 18 in (KOHLER Brevia) to 18-7/8 in (Bemis). Also measure the bolt spacing; every seat here is built for 5-1/2 in (140 mm) centres per its maker. If you are deciding on the bowl shape itself rather than replacing a seat, our round toilet vs elongated toilet comparison covers that choice.
Four of the five seats are plastic (KOHLER calls it plastic construction; American Standard names polypropylene; Delta’s sheet does not name the material); the Bemis 1500EC is enameled molded wood. The practical difference the makers document is care: Bemis’s guide allows only mild soapy water and warns that harsh chemicals can rub away or corrode the paint finish, while KOHLER, Delta and American Standard also restrict cleaning to mild soap and warm water without abrasives or aerosols. Our wood vs plastic toilet seats comparison goes into comfort and durability in more depth.
Four seats here document a damped closing action: KOHLER’s Quiet-Close on the Brevia and Hyten, Delta’s Slow-Close on the Morgan and American Standard’s “No Slam” slow close on the Traditional. The Bemis 1500EC has standard hinges; Bemis sells slow-close versions as separate models. Two maker notes apply to any damped hinge: Delta says forcing the seat closed can cause loss of the slow-close function, and says a failed slow-close means replacing the seat.
Three seats document a seat that comes off the bowl without tools: the Bemis 1500EC (Easy-Clean & Change hinges that unlock), the KOHLER Hyten (Quick-Release button) and the American Standard Traditional (two inside buttons). The KOHLER Brevia K-20110 and the Delta Morgan do not; KOHLER’s quick-release Brevia is the separate K-4774. If cleaning behind the hinges is a priority, choose from the first three.
The makers’ instructions differ on where the fastening happens. KOHLER’s Hyten fastens from above the bowl with a screwdriver; American Standard includes both top-mount and bottom-mount hardware; the Bemis and the Delta take a bolt from above and a nut or wing nut tightened from under the bowl, with a screwdriver. None of the five makers describes its installation as tool-free. All five list plastic hinges. A seat that shifts is usually a loose bolt: American Standard’s manual says to check bolt tightness from time to time, and the Bemis and Delta sheets show the nut under the bowl that you would re-tighten; if a hinge post is cracked or a bolt will not hold, our toilet seat hinge and replacement hardware reviews cover replacement hardware.
An elevated seat such as the KOHLER Hyten mounts on the existing bowl and adds height through the seat itself, 3 in in the Hyten’s case, which KOHLER describes as a more comfortable height for those with limited mobility, for residential use only. A comfort-height toilet is a different product: the bowl itself is taller and takes an ordinary seat. Choose the seat when the toilet is fine and you want a reversible change; look at the fixture when you are already replacing it or want the height built in. Our standard toilet vs comfort height toilet comparison and our comfort height and ADA toilet reviews cover that larger decision, and our best elevated and raised toilet seats guide covers the elevated-seat category.
Every seat here has a one-year maker warranty in writing: KOHLER’s from the date of installation, Delta’s and American Standard’s from purchase for the original purchaser, and Bemis’s “a minimum of one year” from purchase. Delta excludes commercial use, Bemis limits enameled-wood seats to residential use, and American Standard’s warranty is void for a seat bought from an unauthorized seller, so note who the seller is when you order. None of the makers’ documents we read promises a lifetime warranty on these seats. Once you have the right seat, our how to install a toilet seat guide walks through the swap.
Swapping a seat is a screwdriver job for most people. If the bowl is cracked around the bolt holes, the toilet itself needs replacing, or you want the work done for you, search PlumberArchive.com — the US plumber directory.

An elongated seat is longer from the bolt holes to the front, close to 18-1/2 in on the bowl, against close to 16-1/2 in for a round bowl; the two are not interchangeable. All five seats in this roundup are elongated, and their makers list bolt-to-front seat lengths from 18 in to 18-7/8 in. Measure your bowl from the bolt holes to the front rim before ordering.
If a slamming lid is the problem, yes: KOHLER, Delta and American Standard each document a damped lid and seat on the seats here, and the Bemis is the one seat without it. Delta’s caution applies to all of them: do not force a slow-close seat shut, because that can cost it the damping, and a damper that has failed is not repairable on these seats.
Measure from the centre of the seat bolt holes to the front tip of the bowl rim, and the distance between the bolt holes. Every seat here is made for 5-1/2 in (140 mm) bolt centres per its maker, and each maker says its seat fits most elongated toilets; Delta adds that its seat has about 1/2 in of adjustment.
The Bemis 1500EC (Easy-Clean & Change hinges), the KOHLER Hyten (Quick-Release button) and the American Standard Traditional (two inside buttons) are documented by their makers as lifting off without tools. The KOHLER Brevia K-20110 and the Delta Morgan are not.
KOHLER does not say so. Its documents describe a 3 in raised seating surface as a more comfortable height for those with limited mobility, cite IAPMO/ANSI Z124.5, and mark the seat for residential use only; we make no ADA claim for it. For fixtures sold as ADA-compliant, see our comfort height and ADA toilet reviews.
Measure the bowl, then choose by function. For a quiet-closing plastic seat with fixed hinges, the KOHLER Brevia K-20110-0 is documented by KOHLER with Quiet-Close, Grip-Tight bumpers and Quick-Attach hardware. For a wood seat that lifts off for cleaning, the Bemis 1500EC is the one enameled-wood seat here, made in the USA per Bemis, without slow close. The Delta Morgan 811903-WH pairs Slow-Close with NoSlip bumpers and about 1/2 in of fit adjustment, per Delta. The KOHLER Hyten K-25875-0 is the elevated option, with a 3 in rise, Quiet-Close and a Quick-Release button, for residential use. The American Standard 5020A65G.020 combines slow close, the Ever-Tite locking hinge and a two-button lift-off.
All five makers give a one-year warranty in writing with cleaning conditions, so keep the receipt and the care guide. If the toilet has other problems alongside the seat, our how to fix a running toilet guide covers the common causes, and our toilet repair kit reviews cover the tank parts.
