What are the different types of bathtub stoppers available in the market and how do they work?

There are three main types of bathtub stoppers available in the market: pop-up stoppers, push-pull stoppers, and lift-and-turn stoppers.

Pop-up stoppers are commonly found in modern tubs and are operated by a lever on the overflow plate. When the lever is lifted, the stopper closes to hold water in the tub, and when it is pushed down, the stopper opens to allow water to drain.

Push-pull stoppers are operated by pushing or pulling the stopper itself to open or close the drain. These stoppers are typically found in older tubs and are easy to use.

Lift-and-turn stoppers require the user to lift and then turn the stopper to open or close the drain. These stoppers are durable and reliable, but may be more difficult to operate compared to other types.
