Kohler Karing Intelligent Toilet with Integrated Bidet

The Kohler Karing positioning

The Karing (K-77780-CD-0) is Kohler's first-generation intelligent toilet, originally launched in 2010 as the brand's entry into the integrated smart-toilet category. The Karing predates both the Numi (Kohler's premium-luxury smart toilet, launched 2011) and the Veil Smart (Kohler's mid-premium smart toilet, launched ~2018). It's the toilet that proved Kohler could compete with TOTO Neorest in the integrated washlet segment — and although newer models have largely taken over Kohler's smart-toilet marketing focus, the Karing is still in production and available through Kohler dealers and special-order channels.

At $3,580-$4,880, the Karing sits between the Veil Smart ($3,580-$4,580) and Numi 2.0 ($6,580-$7,980) in Kohler's intelligent-toilet lineup. The pricing overlap with Veil Smart isn't accidental — these two models compete for similar buyers. The Karing is the older sibling with more conservative styling; Veil Smart is the newer model with refined Reach flush technology and updated electronics. For buyers who want a Kohler intelligent toilet with traditional silhouette rather than modern sculptural, the Karing remains the right pick.

How the Karing differs from Veil Smart and Numi

The Karing's positioning in 2026 is essentially "the traditional-styled Kohler intelligent toilet for buyers who don't need the contemporary architecture of Veil Smart or the gimmicky feature breadth of Numi 2.0." It's the right pick when bathroom design favors classical or transitional aesthetics over modern.

The integrated feature set

• Tankless dual-flush operation — Class Five mechanism adapted for electronic dual-flush actuation. 0.8 GPF light flush + 1.4 GPF full flush. Both volumes meet WaterSense (1.4 is below the 1.28 threshold for WaterSense Most Efficient but within standard WaterSense per Kohler's spec).
• Integrated bidet wash — rear wash, front wash (feminine cleansing), oscillating wash. Water temperature adjustable through remote control (cold, body-temp, warm, hot). Water pressure 5 levels. Nozzle position adjustable forward/back through controls.
• Heated seat with 5 temperature settings + eco mode for off-hours power savings
• Warm-air dryer — 5 temperature settings, typical 60-90 second drying cycle
• Auto open/close lid — motion sensor opens lid as user approaches; closes 30 seconds after departure
• Auto-deodorizer with replaceable carbon filter cartridge (~$25, 6-month replacement interval)
• Soft-light night LED — illuminates bowl interior for nighttime use without overhead light
• Wireless remote control — wall-mount remote panel with all functions
• Self-cleaning wash nozzle — nozzle cleans before and after each use
• Tankless instant water heating for bidet wash — no warmup wait

The Class Five Dual-Flush — Karing-specific engineering

The Karing uses Kohler's Class Five flush mechanism in an electronically-actuated dual-flush configuration. Unlike the AquaPiston canister found in Memoirs/Maxton/Adair, the Karing's flush uses a modified flapper that lifts to different heights for light vs full flush. The electronic flush button on the remote sends a signal to the seat-mounted control board, which activates the trip-lever solenoid to lift the flapper to either the 0.8 GPF position or the 1.4 GPF position.

Performance characteristics:

• MaP score: 800g (comparable to other Class Five Kohlers)
• Flush time: ~6 seconds
• Audible flush noise: quieter than traditional flapper toilets due to electronic control over flapper lift timing
• Service: when the flapper eventually fails, replacement is a Class Five universal flapper ($5-$15 from any Home Depot)

The Karing variant matrix

What's in the box

• Karing integrated bowl + tankless mechanism + electronics (~135 lbs as single unit)
• Wireless wall-mount remote control with batteries
• Water supply tee adapter (for splitting flow between flush valve and wash function)
• Power cord (~6 feet) for connection to GFCI outlet
• Installation manual + floor template
• Wax ring NOT included — buy separately ($5-10)
• Auto-deodorizer carbon filter (pre-installed)

Install requirements

• GFCI electrical outlet within 3 feet of toilet base — required. Same as Numi, Veil Smart, Neorest. Adding electrician install: $200-$450 if not present.
• Stable water-supply pressure: 25+ PSI dynamic. Verify with pressure gauge before purchase. Tankless flush requires consistent supply pressure.
• Standard 12" rough-in.
• 3/8" compression-fit water supply with included tee adapter.
• Two-person install required — 135 lb single unit, heavy and awkward to maneuver.
• Floor must be flat — same as other tankless one-piece smart toilets.

The install procedure (90 minutes, two people)

1. Remove existing toilet. Scrape wax ring off the floor flange. Inspect flange — verify at finished-floor level, not protruding above.
2. If floor is out-of-level, use Korky setting compound ($6) to create flat seating surface.
3. Install new wax ring on the flange. Horn-style ($6) recommended for centered seal on the tight-tolerance bowl outlet.
4. Two people: lift Karing straight down onto wax ring. Press straight down — no twisting.
5. Use the supplied mounting hardware to anchor bowl to flange. Hand-tight + 1/4 turn maximum.
6. Install water-supply tee adapter between angle stop and Karing's water supply connection.
7. Connect the Karing's main supply line to the tee adapter.
8. Plug the Karing power cord into the GFCI outlet.
9. Pair the wireless remote control with the seat (button-press sequence per manual).
10. Open shutoff valve. Test all functions: flush (light and full from remote), wash, dryer, heated seat, lid auto-open.
11. Check for leaks at supply connection, tee adapter, and base of bowl.

Total install cost (US, all-in)

• Karing unit: $3,580-$3,980
• GFCI outlet installation (if not present): $200-$450
• Wax ring + minor supplies: $20-$40
• Plumber labor: $300-$600
• Total turnkey: $4,100-$5,070

What owners report (5-15 year ownership — Karing has been in market since 2010)

• Feature reliability has matured. 2010-2015 production runs had some early-model electronics issues; 2018+ production is much more reliable. If you're buying a 2024+ Karing, the electronics package is mature.
• Day-to-day feature use matches Veil Smart. Heated seat, integrated wash, dryer, auto-lid all perform comparably.
• The traditional silhouette is the buying reason for many owners. Karing pairs well with classical-styled bathrooms (claw-foot tub, pedestal sink) where Veil Smart's contemporary architecture would feel out of place.
• Service life on electronics: 10-12 years typical. Slightly shorter than Veil Smart due to older electronics architecture. Service through Kohler customer service.
• Service life on porcelain: 25+ years.
• Replacement parts: deodorizer carbon filter replaced every 6 months ($25). Electronic seat module: $400-$700 when failure occurs (typically 10+ years).
• The retired-then-renewed status: Kohler stopped marketing the Karing actively around 2018 but kept the product in production. Today, the Karing is a "still available but not promoted" SKU — buyers find it through Kohler dealers, special-order, or online channels.

Where Karing wins vs Veil Smart

• Traditional silhouette for classical-styled bathrooms (Veil Smart is contemporary)
• Dual-flush 0.8/1.4 GPF (Veil Smart is single-flush 1.28 GPF)
• Comparable or lower price in some configurations
• Slightly cleaner aesthetic for traditional bathrooms with chrome/brass fixtures rather than brushed nickel modern

Where Veil Smart wins vs Karing

• Newer electronics architecture — 10-12 year service life vs Karing's 8-10 (post-2018)
• Pure-Clean glaze (Karing has standard ceramic only)
• UV bowl sanitization cycle (Karing doesn't have UV)
• Side-mount touchscreen on seat for quick access (Karing is remote-only)
• Broader US distribution — Veil Smart is more widely available

Where Karing competes vs TOTO Neorest 700H

The verdict — should you buy a Karing?

Buy if:

• You want a Kohler intelligent toilet with traditional silhouette (not Veil Smart's contemporary)
• Bathroom design is classical or transitional
• You prefer dual-flush operation in a smart toilet
• You've located a Karing through Kohler dealer at a price competitive with Veil Smart

Skip and choose Veil Smart if:

• You want the newer electronics architecture and Pure-Clean glaze
• Bathroom is contemporary or modern
• You want UV bowl sanitization
• Broader retail availability matters

Skip and choose Numi 2.0 if:

• You want every smart-toilet feature (Alexa, speakers, mood lighting, foot warmer)
• Budget allows the $6,500+ tier

Warranty

Kohler Karing residential warranty: 1 year on labor, 1 year on electronics, lifetime on porcelain. Service through Kohler customer service. The Karing's electronics service network is smaller than the newer Veil Smart / Numi line — repair lead times can run 1-3 weeks longer.

Pricing reality (2026)

Karing K-77780-CD-0 (White): $3,580-$3,980. Kohler dealers and Ferguson Bath Gallery: $3,180-$3,580 for trade buyers. Build.com Pro Desk: $3,280-$3,580. Home Depot rarely stocks the Karing — typically special-order with 4-8 week lead time. Designer colors +$200-$1,300 depending on color and channel.

The honest summary

The Karing is the Kohler intelligent toilet that hasn't quite gone away. It's been the "older sibling" in Kohler's smart-toilet lineup for 6+ years, with newer Veil Smart and Numi 2.0 taking the marketing spotlight. For traditional-bathroom buyers who specifically want classical styling in an intelligent toilet, the Karing remains the right pick. For everyone else, Veil Smart (more contemporary) or Numi 2.0 (more features) are the natural upgrade paths.
