The Kohler San Souci K-5172-RA-0 is a premium one-piece compact elongated toilet that offers the same small-footprint format as the standard San Souci with a right-hand trip lever configuration. Its concealed trapway gives the base a cleaner appearance, and the 1.28 GPF AquaPiston flush is designed for efficient everyday residential use. Because the seat is sold separately, it leaves buyers free to choose the exact seat style they want.
What rough-in does the San Souci K-5172-RA-0 require?
This model uses a standard 12-inch rough-in. Measure from the finished wall to the center of the closet bolts before buying so the one-piece concealed-base body fits the drain location correctly. That quick measurement is the simplest way to avoid installation trouble.
How well does the AquaPiston flush perform on this compact elongated toilet?
The AquaPiston system is designed to move water rapidly through a canister-style flush valve while staying at 1.28 gallons per flush. That helps it deliver a strong gravity flush without reverting to older, higher-water-use designs. For most homeowners, it should feel like a mainstream full-performance flush in a smaller-footprint toilet.
What is the difference between a left-hand and right-hand trip lever?
The trip lever position is described from the perspective of a person seated on the toilet. On this K-5172-RA-0, the handle is on the right-hand side when seated, whereas a left-hand version places it on the left side. That distinction mainly matters for matching adjacent cabinetry, user preference, or replacing an existing toilet with a familiar handle location.
What does Comfort Height add on a compact elongated model?
Comfort Height raises the seating position closer to standard chair height, which many adults find easier for everyday use. That means you can get the space-saving benefit of a compact elongated bowl without giving up a taller, more accessible seating posture. It is a useful combination in small bathrooms that still serve as primary spaces.
Is this toilet water efficient and WaterSense certified?
Yes. The 1.28 GPF rating lowers water use compared with many older toilets while keeping the familiar feel of a gravity-flush design. Under the rules for this dataset, 1.28 GPF products are marked WaterSense certified. That gives this premium-format one-piece toilet solid efficiency credentials.
