Buying advice

When choosing a toilet flange cap, ensure it matches your flange size (typically 3 inches) and material (PVC or ABS). Consider the cap's durability for temporary vs. permanent sealing. Snap-on designs offer convenience, while screw-on types provide a more secure fit. Always check for compatibility with your specific flange type.
