How do I know if I have the 2026 version?

Check the serial number on your TUSHY Wave or Oasis bidet seat. The first four digits represent the month and year in MMYY format. If it reads 0825 or higher, you have a 2026-version unit and this replacement will fit. Serial numbers before 0825 require a different version.

Can I replace just the lid or just the seat?

Yes. Both the lid and seat detach independently using a sliding lock. This set includes both, but you can order them separately if only one component is damaged.

What if I ordered the wrong bowl shape?

The lid and seat can be swapped independently. If you have an elongated bowl, you can order the elongated versions and exchange them, giving you a complete set in the correct shape.

Will this fit other bidet brands?

No. This replacement is designed specifically for TUSHY Wave and Oasis bidet seats and will not attach to other brands or models.

Is installation difficult?

No. You unlock a sliding mechanism and detach the old seat or lid, then slide the new one into place. The process takes a few minutes once you locate the release.

Replacement Soft-Close Seat and Lid for TUSHY Wave or Oasis (Round)

Most bidet seat replacements force you to buy the entire unit when only the lid hinge cracks or the seat surface dulls. This pair lets you replace just the worn components, extending the life of a bidet that still cleans perfectly well. The soft-close feature is the detail that matters most—cheap seats slam shut or drift open, and a toilet lid that bangs at two in the morning is reason enough to replace it. This one dampens the descent reliably, and the seat design avoids the seams and textures that collect grime on bargain replacements.

Good gift when

The details

This replacement set gives your TUSHY Wave or Oasis bidet seat a fresh start when the original lid or seat shows wear, cracks, or no longer closes smoothly. The soft-close mechanism prevents slamming, and the seat is designed for straightforward cleaning without hard-to-reach crevices.

Both pieces attach and detach using a sliding lock mechanism, so swapping them takes a few minutes once you understand the release. The round shape fits standard round toilet bowls, which measure roughly circular rather than elongated.

This version is engineered for units manufactured from August 2025 forward. Serial numbers on your bidet seat begin with a four-digit date code in MMYY format; if yours reads 0825 or later, this is the correct replacement. Earlier units require a different version with slightly different mounting details, so checking your serial number before ordering prevents a mismatch.

You can replace the lid and seat together or order them separately if only one component needs attention. Both are included in this set. If you discover you have an elongated bowl after ordering, the lid and seat can be swapped independently for the correct shape, giving you flexibility if your home has multiple toilet configurations.
