A Glacier Bay toilet can have more than one useful number. That confuses a lot of people searching for a replacement tank lid because the number from a store label may not be the same number used by the manufacturer or parts documentation.
Retail item number vs. model number
A good example is the Glacier Bay dual-flush toilet sold as Item 215-583 and identified in its manual as Model N2316. Niagara's own support material also groups N2316 under Glacier Bay dual-flush toilets. Both numbers are therefore useful search terms for the same toilet family.
Why this matters when buying a lid
If you search only one number, you can miss a valid listing filed under the other number. Replacement sellers may organize inventory by the tank model, retailer item number or lid number depending on how the original part was marked.
What to record
- Every number printed inside the tank
- Any Home Depot or retailer item number you still have
- The model number from the original manual
- Numbers under the old lid, if available
- Whether the toilet is single flush or dual flush
- Width, depth and shape of the lid
Do not assume two Glacier Bay lids interchange because they are both dual flush or look similar. Confirm the model and dimensions.
