Some of the most common materials toilet seats come in include:
Most toilet seats are made primarily of plastic. That makes them lightweight and less prone to warping from moisture. They often tend not to be painted, so paint will not bubble and crack if you get water on the toilet seat. They also tend to be less expensive. Plastic is easy to clean, too. Choose a plastic toilet seat if you're looking for a no-fuss product with minimal care.
These are typically chosen with style in mind. You can add rich texture to your bathroom space with a wooden toilet seat. Some styles may also be molded on the top to provide a different texture, like faux stone.
You can also find toilet seats in specialty materials. One example is Polyresin. This can create a clear appearance where you can see straight into the bowl. Often, this material may have objects set into it to create a theme, such as set-in seashells. This is another material with style as the main focus.
You can also find toilet seats that are acrylic. Choose these for their durability. The acrylic may also be used as a glass style coating that gives more sheen; it often covers and protects certain designs on the lid.
