There are several types of sink drain stoppers, including pull-out, twist-and-pull, and pop-up. Pull-out sink stoppers can be removed by pulling on the stopper until it comes out of the drain. A twist-and-pull design requires lifting then turning the stopper to lock it in an open position and the opposite action (turning, then pressing down) to close it. A pop-up sink stopper works by pushing down the drain cover to open or close the passageway. 

The time it takes to install a sink depends on whether you hire a professional or do it yourself, as well as the complexity of the job. A professional plumber can typically install a sink in 1 to 4 hours, with most routine jobs taking around 1 to 2 hours. However, more complicated installations will take longer. Projects that involve rerouting plumbing, installing an under-mount sink, or making countertop modifications can take a full day. Installing a sink with a prefab vanity could also stretch the project to 6 to 8 hours. If you plan to install the sink yourself, you should set aside 4 to 6 hours, though it could take longer. It's also recommended to have a friend help, especially if you are working with a heavy sink made of a material like porcelain.

DIY is not recommended for commercial settings due to safety and code compliance. Hire licensed professionals.

Yes, it is often possible to replace an undermount sink without removing the countertop, but success can depend on the countertop material. For materials like granite, the process is relatively straightforward. However, laminate or uniquely shaped countertops might need to be removed or modified.

The process typically involves shutting off the water supply, disconnecting the drain and plumbing pipes, cutting through the old silicone seal, and carefully lowering the sink from below. This requires a good understanding of plumbing and the right tools. If you are not confident in performing the replacement yourself, it is recommended to hire a countertop specialist or a plumber to handle the task.
