How do I know if I need the 2026 or 2025 version?

Check the serial number on your bidet base. The first four digits are the date code in MMYY format. If it reads 0825 or later, you need the 2026 version. Earlier codes require the 2025 version.

Can I return this if I ordered the wrong version?

No. This is a final-sale item and cannot be returned or exchanged once purchased.

Does this include the lid?

No. The seat is sold separately from the lid. If you need both, order the matching lid alongside this seat.

Will this fit a round toilet bowl?

No. This seat is elongated and measures 19.4 inches long. If you have a round bowl, order the round seat version instead.

Do I need tools to install this?

No. The seat attaches through a sliding lock built into the bidet base. You unlock the mechanism, remove the old seat, and snap the new one into place.

Replacement Elongated Seat for TUSHY Wave and Oasis Electric Bidets

Most bidet seats crack, stain, or loosen over time, but electric bidet manufacturers rarely sell individual replacement parts. You end up scrubbing a dingy seat or replacing the entire unit because a single plastic component failed.

TUSHY sells this seat separately and designs it to snap on and off in seconds. If your seat cracks or you move to a toilet with a different bowl shape, you replace just the worn piece. The sliding lock makes installation tool-free, and the modular system means you can swap between round and elongated configurations without buying a second bidet. Worth it if you already own a compatible unit and want to stretch its working life past the first crack or stain.

Good gift when

Anyone whose bidet seat has cracked or stained beyond cleaning

Skip it if You own a Wave or Oasis manufactured before August 2025, or your toilet has a round bowl instead of elongated. Check your serial number date code before ordering, because this part cannot be returned.

A practical replacement part for someone who already owns a compatible bidet.

The details

This is the elongated seat that ships standard with TUSHY Wave and Oasis electric bidet models manufactured from August 2025 forward. It replaces damaged or worn seats on compatible units, attaching through the same sliding-lock system built into those bidet bases.

The seat measures 19.4 inches long by 14.7 inches wide, sized for elongated toilet bowls. Installation requires unlocking the sliding mechanism on your existing bidet unit, removing the old seat, and snapping the replacement into place. The process takes a couple of minutes and needs no tools.

This part works only with Wave and Oasis units that carry a serial number date code of 0825 or later. Units manufactured before August 2025 use a different seat design and require the 2025-version replacement instead. The serial number appears on the bidet base and includes a four-digit date code where the first two digits represent the month and the second two represent the year.

If you ordered the wrong bowl shape—round instead of elongated, or the reverse—you can purchase both the correct seat and the matching lid to convert your bidet for a different toilet. Once swapped, the parts remain interchangeable for future moves or bowl changes.

The seat is sold individually. Lids are available separately. This is a final-sale item and cannot be returned once opened.
