Pros & cons
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
- ✓One-button auto wash-and-dry cycle is a favorite among owners buying for elderly parents or post-surgery recovery
- ✓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
- ✓Dynamic hot-cold 'therapy' stream is a niche but loved feature for hemorrhoid sufferers
- ✗Peak spray is softer than the pump-driven BB-2000 — Reddit users 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
- ✗Tankless heater briefly passes cool water at spray start — a second or two before it warms, which tank-heater owners aren't used to
- ✗No app support or user profiles at a price point where the Alpha JX and Brondell Swash 1400 offer programmable presets
- ✗Like most tankless designs it needs decent household water pressure; low-flow homes report weaker spray than spec suggests
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
- ✓Oscillating front wash plus adjustable stainless nozzle covers rear and feminine cleaning well beyond most upper-tier rivals
- ✓Costco's generous return policy effectively papers over the short factory warranty for club members
- ✓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
- ✗17-lb shipping weight and taller back hump make installation more awkward than the slim BB-500
- ✗Availability is Costco-centric; when the club rotates it out, the $699 direct price is hard to justify against the Discovery DLS
- ✗Auto-lid sensitivity annoys some owners — it opens for pets and cleaning passes, cycling the motor constantly
