American Standard Studio S One-Piece Elongated 1.28 GPF Toilet

The American Standard Studio S positioning

The Studio S (2786.128) is American Standard's modern-designer one-piece — part of AmStd's Studio S bath collection that includes contemporary faucets, lavatories, tub fillers, and accessories. At $580-$820, the Studio S occupies the modern-designer one-piece tier in AmStd's lineup, alongside the contemporary Boulevard ($580-$820) and the classical Heritage VorMax ($540-$780). The Studio S distinguishes itself with even cleaner contemporary architectural styling and a more concealed-trapway exterior than the Boulevard.

For buyers spec'ing AmStd Studio S faucets and lavatories, the Studio S toilet provides the bath-suite coordination. For standalone buyers, the Studio S competes more with Boulevard than across brands — both are AmStd modern one-piece options with VorMax flush + EverClean + Right Height. The choice between them is primarily aesthetic preference within AmStd's contemporary designer tier.

Studio S vs Boulevard — picking between AmStd modern one-pieces

The Studio S has slightly better bowl-cleansing performance (VorMax vs FloWise — MaP 900g vs 800g). The Boulevard has slightly broader retail availability. For most buyers, the choice is driven by which bath-suite collection they're coordinating with — Studio S or Boulevard.

The Studio S design language

• Modern architectural silhouette with cleaner geometric edges than Boulevard
• Concealed-trapway exterior — visible bowl from side reads as smooth vertical face
• Slim profile — slightly more compact silhouette than Boulevard while keeping full-elongated bowl
• Top-mount or front-mount trip lever options
• Concealed mounting hardware on some configurations
• EverClean glaze with VorMax water-distribution geometry — the bowl interior is engineered for the circular flush pattern

What owners report

• The modern aesthetic is the buying reason. Owners specifically choose Studio S when bathroom design favors clean contemporary lines.
• VorMax bowl-cleansing performs well — extended cleaning intervals comparable to Heritage VorMax.
• EverClean + VorMax combination stretches manual cleaning to every 4-5 weeks in normal use.
• Service life: 25+ years porcelain.
• The Studio S bath collection is smaller than Heritage or Boulevard — fewer matching fixtures may limit bath-suite coordination.

The verdict

Buy Studio S if:

• You're spec'ing AmStd Studio S collection bath fixtures

• The slightly cleaner exterior vs Boulevard matters

Skip and choose Boulevard if:

• You prefer Boulevard's broader retail availability

Skip and choose Heritage VorMax if:

• Classical traditional bathroom design
