Toilet tank lids, aka tops, aka covers.
There are no numbers on toilets to indicate a color name. American Standard and Kohler have used some alpha abbreviations on off-whites. This was to aid factory workers on similar colors in dim light. BONE = Bone, HTR = Heather, Lin = Linen, SHL = Shell. Kohler uses ALM = Almond, BIS = Biscuit.
Many of our lids are yet to be listed. For more brands, models & colors please call 650-483-1139.
