Bio Bidet Horizon

4.3(350 reviews)

Bio Bidet's newer upper-tier seat, sold mainly through Costco, that brings auto open/close lid, UV nozzle sterilization, and an enhanced multi-stage dryer down from smart-toilet territory. It lists at $699 on biobidet.com but Costco carries it around $499 with promos dipping to $340 — roughly half what the Discovery DLS costs for a similar hands-free experience. Unlimited warm water, wireless remote, heated seat, and night light are all standard.

Pros

  • 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

Cons

  • 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

Electric Bidet Seat
4.4(2,900)

Bio Bidet's long-running flagship seat (now sold under Bemis ownership) and still the spray-strength benchmark of the category in 2026. Its hybrid heater pairs a small tank with on-demand heating for unlimited warm water, and the vortex wash mode delivers a concentrated enema-grade jet no tankless rival matches. Forbes named it Best Bidet Overall in 2025; it lists at $699 but routinely streets in the $420-500 range.

Electric Bidet Seat
4.3(300)

Bio Bidet's modern tankless flagship, styled like a Toto Washlet rival: a 4.7-inch low-profile seat with motorized auto-open lid, UV nozzle sterilization, endless instant-heat warm water, and a minimalist wireless remote. Listed at $899 but selling around $525-600 through 2026, it undercuts the comparable Toto S550e by several hundred dollars while adding a 5-year full warranty. Elongated toilets only.

The updated 'Ultimate' version of the USPA 6800, the seat that introduced a generation of Costco members to bidets. The U adds a night light, two user presets, and a dual-sided LCD remote to the proven dual-nozzle platform with warm-air dryer and carbon deodorizer. Still current on biobidet.com at $399 (list $499), though its 600W reservoir heater and early-2010s styling show their age next to the BB-1200. Elongated and round versions are sold.
