Tushy Aura
Ranked #4 in Best Bidet Toilet Seat Attachments
Tushy Aura
4 sources1 derived$599as of Sep 25

The Tushy Aura offers a premium bidet experience with its auto open/close lid, heated seat, and instant water heating. Reviewers highlighted its hands-free operation, UV sterilization, and oscillating spray as standout features. While praised for luxury and hygiene, some noted its exclusive compatibility with elongated toilets and the need for a wall-mounted remote. It caters to users seeking a high-end bathroom upgrade but may not suit all toilet types.

Strengths
  • — Hands-free auto open/close lid and seat for a luxurious, hygienic experience, per Business Insider
  • — Instant heated seat provides year-round comfort with adjustable temperature settings
  • — Integrated UV sterilization cleans the antimicrobial nozzle every three minutes

How they stack up

Bio Bidet BB-550

The Bio Bidet BB-550 offers heated seat and warm air dryer features that the Bio Bidet SlimEdge and Tushy Classic 3.0 lack, though it requires an electrical outlet. Unlike the Luxe Bidet Neo 320 Plus, it has a low profile that may limit some features, but provides more comfort with its heated seat and warm air drying. Compared to the Tushy Aura, it's less premium but more affordable and still offers basic smart features.

Tushy Aura

The Tushy Aura offers the most premium experience with auto lid, UV sterilization, and oscillating spray, features not found in the Luxe Bidet or Brondell Swash 1400. It's more advanced than the Bio Bidet BB-550 in terms of hygiene and automation, though it requires a wall-mounted remote and is limited to elongated toilets. Compared to the Tushy Classic 3.0, it's more feature-rich but also more expensive and complex.
