Deciding the appropriate waste slot can be rather confusing if you don’t know what your basin type. There are two types of waste options from slotted to unslotted. Neither are better or worse it is down to the type of basin or bathtub you have. If your basin has an overflow, then we recommend a slotted waste function would be best suited. However, if you have a separate hole connection to use the overflow, you would need an unslotted waste. Check out our range of slotted waste options.
