What owners say
Bio Bidet Discovery DLS
- +Motorized auto-open/close lid works reliably on approach — a headline feature usually reserved for $1,000+ seats like the Toto S550e
- +Tankless heating delivers genuinely endless warm water with no 30-second cliff, fixing the biggest complaint about the BB-1000/BB-2000 tank designs
- +At 4.7 inches tall in the rear it's Bio Bidet's slimmest seat, and reviewers say it finally looks like it belongs on a modern toilet
- +UV light sterilizes the stainless nozzle between uses — a hygiene extra even Toto reserves for its ewater+ premium models
- +5-year 100% parts-and-labor warranty is the best coverage in the category, beating the BB-2000's 3 years and Toto's 1
- +The warm-air dryer is notably stronger than the fan in the BB-2000 — one of the few bidet dryers reviewers say they actually finish with
- −Peak spray is softer than the pump-driven BB-2000 — owners coming from a vortex-wash Bio Bidet or strong Toto notice the step down in raw pressure
- −Reviewed.com's tester hit build-quality issues — inconsistent pressure and temperature and a visibly shaking nozzle — so QC seems less consistent than Toto's
- −Confirmation beeps can't be disabled, and the motorized lid is audibly noisier than competitors — annoying in shared or nighttime bathrooms
- −Elongated only; round-bowl owners are pointed back to the older BB-1000/BB-2000
- −The auto-open lid triggers on pets and passers-by in small bathrooms, and several owners end up turning the motion sensor off
- −No app support or user profiles at a price point where the Alpha JX and Brondell Swash 1400 offer programmable presets
Bio Bidet Horizon
- +Motorized auto open/close lid greets you like a $1,000+ smart toilet — the Discovery DLS is Bio Bidet's only other seat with it, at $100+ more
- +Built-in UV sterilizer bakes the nozzle clean after every use, a hygiene step even the Toto S5's EWATER+ handles with chemicals instead of light
- +Enhanced multi-stage warm-air dryer is a real step up from the token dryers on the BB-1200 and BB-2000 — owners say it can actually finish the job
- +Hybrid heating delivers unlimited warm water with no mid-wash temperature sag
- +Costco runs it at $339.99 several times a year — flagship features for BB-1200 money if you time it
- +Low-profile design with concealed cord routing looks far more modern than the decade-old BB-2000 silhouette
- −No deodorizer — an odd omission at $500 when the $399 USPA 6800U and $469 BB-2000 both have one
- −No multi-user presets, so every rider re-adjusts temperature and pressure by hand
- −Elongated only; round-bowl households are out entirely
- −The auto-lid motor is one more thing to break, and a few Costco reviewers report lids that stopped rising after a year
- −1-year warranty is skimpy for a premium seat — Brondell gives three years on the Swash 1400 at a similar street price
- −Availability is Costco-centric; when the club rotates it out, the $699 direct price is hard to justify against the Discovery DLS
