Need help identifying it? Send FixALid a clear photo of the numbers inside the tank, a straight-on photo of the tank opening, and the maximum left-to-right and front-to-back measurements.

Used Condition

Normal cosmetic wear may include light scratches, marks, mineral staining, color variation, or other signs of age. Most of our lids are pre-owned originals, and many are discontinued and hard to find. We will never send you a bad lid. Our goal is to get you the right replacement so you can keep your toilet working. Not sure which lid you need? Send us photos and measurements before ordering, and we’ll help you find the right match.
