Help! I ordered the wrong Wave shape—What should I do?Updated 5 days ago
No worries — this is an easy fix. Whether you didn’t know your toilet’s bowl shape when you ordered, or you’re moving your TUSHY Wave to a new toilet, you don’t need to replace the entire bidet.
Step 1: Confirm your toilet bowl shape
First, double-check whether your toilet is round or elongated. Some toilets are tricky to identify by sight, so measurements are the most reliable way to confirm.
Step 2: Order the correct seat & lid (no full return needed)
If you do have the wrong shape, you can simply order a replacement seat and lid at a discounted rate in the correct shape from our Spare Parts page. Go to step 3 to make sure you order the correct version.
Swapping them out is quick and easy:
- Remove the existing seat and lid
- Snap the new ones into place
- You’re good to go!
Bonus perk: Having both seat shapes can be handy if you move, upgrade your toilet, or switch setups in the future.

Important: Please keep the sliding locks from your original seat and lid — you’ll need them for the replacement.
Step 3: Check your serial number before ordering
Before placing your replacement order, check your Wave’s serial number, located on the back of the unit. This ensures you select the correct seat and lid version.
Your serial number is the key to finding the right replacement seat and lid. Here’s how to decode it: the first two letters identify your model, so WV means TUSHY Wave. The third letter tells you the shape: R means Round and E means Elongated. The next two numbers show the production month, from 01 for January through 12 for December. The following two numbers show the production year, such as 24 for 2024, 25 for 2025, and 26 for 2026.
- Serial numbers with a date code between XXX092400000 and XXX072599999→ Select the 2025 version in the shape you need:
- Serial numbers beginning with XXX082500001 and later→ Select the 2026 version in the shape you need:
Round Seat for Wave/Oasis (2026 Version)
Round Soft-Close Lid for Wave/Oasis (2026 Version)
Elongated Seat for Wave/Oasis (2026 Version)
Elongated Soft-Close Lid for Wave/Oasis (2026 Version)
