How do I know if this fits my TUSHY bidet?

Check the serial number on your Wave or Oasis bidet seat. The first four digits are a date code in MMYY format. If the code is 0825 or later (August 2025 onward), this 2026 version fits. Earlier codes require the 2025 version instead.

Can I install this without removing the entire bidet?

Yes. The seat and lid detach from the bidet base using a sliding lock on each side. You unlock the mechanism, slide the old component off, and slide the new one into place without touching plumbing or the mounting hardware.

Will this work on a round toilet bowl?

No, this version is molded for elongated bowls. TUSHY sells a separate seat and lid set for round bowls. You can order both shapes and swap them if you need to move the bidet between different toilets.

What if I ordered the wrong shape?

You can purchase the other shape separately and swap the lid or seat. Once you have both, you can use whichever matches your current toilet and keep the other for future moves or bathroom changes.

Factory seat and lid replacement for TUSHY Wave and Oasis electric bidets

Most bidet repairs force you to replace the entire seat even when only the lid or seat surface needs attention. This factory part isolates the fix to the components that take the most wear—the surfaces you sit on and touch every day—so a crack, stain, or broken hinge doesn't mean starting over with a full bidet installation.

The date-coded compatibility requirement is stricter than typical toilet seats, but it ensures the hinge mechanism and mounting tabs align exactly with your bidet's base. If your serial number confirms a match, this restores original fit and function without compromise.

Good gift when

People replacing damaged or stained bidet components without buying a new unit

Skip it if Only works with TUSHY Wave and Oasis models from August 2025 onward—earlier serial numbers need a different version, and no adapter bridges the gap.

The details

When a bidet seat or lid needs replacing after years of daily use, this factory part restores your TUSHY Wave or Oasis to original condition without replacing the entire unit. The set includes both the soft-close lid and the easy-clean seat molded to fit elongated toilet bowls.

Both pieces detach from the bidet base using a sliding lock mechanism, making installation straightforward without tools or plumbing work. The soft-close hinge prevents slamming, and the smooth seat surface wipes clean without crevices that trap grime.

This replacement fits TUSHY Wave and Oasis electric bidet seats manufactured from August 2025 forward. Compatibility depends on the serial number date code stamped on your bidet unit—models produced before that cutoff require a different version. The seat measures 19.4 inches long by 14.7 inches wide to match elongated bowl dimensions.

If you ordered the wrong bowl shape initially, you can purchase the corresponding round or elongated lid or seat separately and swap components to match your toilet. Once you have both shapes on hand, you can move the bidet between different bathrooms as needed.
