Product Overview

The one-piece design of this Santa Rosa toilet adds a contemporary look to your powder room. Perfect for smaller bathrooms and powder rooms where space is at a premium, the compact elongated shape takes up the same space as a round-bowl toilet, yet its elongated shape adds added comfort. Its 1.28-gallon high-efficiency flush provides water savings of up to 16,500 gallons per year versus an old 3.5-gallon toilet, without sacrificing performance. Revolution 360 flushing technology keeps the bowl clean longer and combines with ContinuousClean ST system to dispense cleaning solution with every flush. Chair-height compact elongated seat makes it comfortable to use, and a Quiet-Close seat is included.


  • One-piece toilets integrate the tank and bowl into a seamless, easy-to-clean design
  • Compact elongated bowl offers added comfort while occupying the same space as a round-front bowl
  • Comfort Height feature offers chair-height seating that makes sitting down and standing up easier for most adults
  • 1.28 gpf (4.8 lpf)
  • Left-hand Polished Chrome trip lever
  • 2-1/8" (54 mm) fully glazed trapway
  • Revolution 360 flushing technology generates a forceful swirling motion to keep the bowl clean longer
  • CleanCoat surface treatment inhibits the growth of water scale and mineral stains for improved ease of cleaning
  • ContinuousClean system automatically dispenses cleaning solution with every flush
  • Works with any white toilet bowl cleaner tablet. Tablets last up to six months in ContinuousClean ST system
  • Precision-engineered tank, bowl, and trapway create strong siphon during flushing
  • AquaPiston canister optimizes the flow out of the tank, harnessing gravity and the natural powerful reducing cascade of water to increase the power and effectiveness of the flush
  • Easy-to-flush canister design requires less force to actuate than a 3" (76 mm) flapper, and has 90% less exposed seal material which resists conditions that cause wear, tear, shrinkage and swelling


  • Standard 12" (305 mm) rough-in
  • Supply line sold separately
