American Standard 4215A Two-Piece Elongated 1.6 GPF Toilet (Legacy)

This is a legacy product page. The American Standard 4215A is discontinued from current AmStd production. This page exists to help owners with existing 4215A installations find replacement parts and identify the modern equivalent. If you're shopping for a new toilet, see the Edgemere — the current AmStd product that replaced the 4215A in production.

The American Standard 4215A — what it was and where it lives now

The 4215A was American Standard's volume mid-tier two-piece elongated toilet from approximately 1995 through 2015 — discontinued around the time AmStd transitioned to the Edgemere (765AA.104) as the replacement SKU. During its 20-year production run, the 4215A was spec'd in millions of US tract homes, multi-family construction projects, and rental property rebuilds. If you live in a 1990s-2010s US home with an "American Standard" elongated two-piece toilet, there's a meaningful chance it's a 4215A.

The 4215A search volume (620 SV/mo for "american standard toilet 4215a") reflects current homeowners trying to repair or replace existing 4215A installations — not new buyers shopping for the model. This page covers the practical realities of living with a 4215A in 2026.

Identifying your 4215A

The 4215A model number is printed in three possible locations:

• Underside of the tank lid — most common. Look for "4215A" or "4215.A" stamped or printed on the inside of the lid.
• Inside the back wall of the tank — stamped into the porcelain (less common but present on some production runs)
• Outside back of the tank, low — small ink-stamp near the supply-line connection

The 4215A typically appears in White, Linen, and Bone color codes. Almond was offered through approximately 2005 production.

4215A specifications (for parts ordering reference)

• Bowl shape: Elongated (18.5" front-to-back from bolt holes)
• Height: Standard 14.625" (not Comfort Height)
• Rough-in: 12 inches (US standard)
• Flush valve: 2-inch standard gravity
• Flapper size: 2-inch — universal Korky 100 or Fluidmaster 502P21 fits perfectly
• GPF: 1.6 (initial production) — some later production runs (2010+) were 1.28 GPF designated as 4215A.014
• Mounting hole pattern: US-standard 5.5" floor flange bolt pattern
• Tank-to-bowl gasket: Universal Korky 481BP kit fits

Common 4215A repair scenarios in 2026

Replacing the flapper

The 4215A uses a standard 2-inch flapper. Replacement is universal:

• Korky 100 (2-inch universal) — $5-$8, fits perfectly
• Fluidmaster 502P21 (2-inch universal) — $6-$10
• American Standard 7301114-0070A (OEM 2-inch flapper) — $9-$14, if you want genuine AmStd parts

The 4215A's flapper service life is typically 5-7 years. If yours is 15+ years old without replacement, the rubber is almost certainly hardened — replace it as preventive maintenance.

Replacing the fill valve

The 4215A uses a standard Fluidmaster-pattern fill valve. Replacement:

• Fluidmaster 400A (universal) — $10-$15, drop-in replacement
• Korky 528 — $10, alternative
• American Standard OEM fill valve — $20-$25, genuine AmStd

Replacing the tank-to-bowl gasket

After 15-25 years of service, the rubber tank-to-bowl gasket hardens and starts leaking. Symptoms: water dripping behind the toilet, dampness at the tank-to-bowl junction. Replacement:

• Korky 481BP universal kit (gasket + 2 brass bolts + washers) — $12-$18
• American Standard 7301241-0070A OEM kit — $20-$25

The gasket replacement procedure requires draining the tank, unbolting the tank from the bowl, replacing the gasket, and rebolting — about 45 minutes DIY.

Replacing the tank lid (the hard part)

Tank lid breakage is the most-frustrating 4215A repair scenario because tank lids are discontinued from current AmStd production. Sourcing options in 2026:

• Replacements.com — searchable inventory of discontinued porcelain. Search "American Standard 4215A tank lid" + your color code. Typical price: $140-$240 for white; $200-$350 for designer colors (Linen, Bone, Almond).
• eBay — broken 4215A units often get parted out by sellers. Search "4215A tank lid" — pricing varies $80-$280 depending on condition and color.
• This Old Toilet (thisoldtoilet.com) — US specialty supplier for discontinued tank lids. Search by model number.
• AmStd Customer Service direct — special-order production of tank lids for discontinued models is sometimes possible with 6-12 week lead time and $250-$400 pricing.
• Local plumbing supply houses — older supply houses sometimes have warehoused old-stock 4215A lids. Worth a phone call if local sourcing matters.

The modern equivalent — Edgemere (the upgrade path)

When your 4215A finally fails beyond repair (cracked bowl, broken tank, severe internal corrosion), the modern AmStd equivalent is the Edgemere (765AA.104). The Edgemere shares:

• Standard 12" rough-in — direct swap-in compatibility with the 4215A
• Elongated bowl shape — though Edgemere is compact-elongated (17.5") vs 4215A's full elongated (18.5"). For typical residential install, the 1-inch difference is barely noticeable.
• AmStd brand pedigree — same lifetime porcelain warranty
• Right Height (17.25") — meaningful comfort upgrade from 4215A's standard 14.625"
• WaterSense 1.28 GPF — modern water-efficiency compliance
• EverClean glaze standard — bowl-cleaning interval upgrade

The transition from 4215A to Edgemere is typically a 75-minute single-person swap install — same procedure as replacing any other 12" rough-in two-piece toilet. The Edgemere fits the 4215A's existing floor flange without modification.

Should you keep repairing the 4215A or upgrade?

The economic threshold:

• Worth repairing: 4215A in good cosmetic condition + repair cost under $100 + you don't mind 1.6 GPF and 14.625" standard height. Flapper, fill valve, gasket replacements all fall in this range.
• Borderline: 4215A with cracked tank lid + sourcing cost $200+ vs Edgemere replacement at $420-$580. Many owners choose replacement at this point.
• Worth replacing: 4215A with cracked bowl, severe internal corrosion, or multiple parts failing. Replacement with Edgemere or Cadet 3 makes more sense than continued repair.

The verdict for current 4215A owners

If your 4215A is functional but aging:

• Keep universal aftermarket parts (Korky 100 flapper, Fluidmaster 400A fill valve, Korky 481BP gasket kit) on hand for repairs
• Source a backup tank lid through Replacements.com or eBay before yours breaks ($140-$250 investment for peace of mind)
• Plan eventual upgrade to Edgemere (modern equivalent) or Cadet 3 (value-tier modern equivalent) when major component fails

Pricing reality (2026)

The 4215A is no longer sold new. Used/old-stock pricing through Replacements.com and eBay typically: $180-$340 for a complete unit (uncommon — most are parted out). Tank lid only: $80-$280 depending on color. Universal repair parts (flapper, fill valve, gasket) total $25-$45 if all three need replacement.

If you're looking to buy a similar toilet new, the Edgemere (765AA.104) at $420-$580 is the direct modern equivalent.
