Flexstone Vs Swanstone Vs Onyx For Your Shower [Pros, Cons, & Differences]

Choosing the right bathroom fixtures is essential not only to make them more aesthetically pleasing but also to make them more functional and durable. There are many options in the market, but Flexstone, Swanstone, and Onyx might have caught your attention because of their notable qualities. So, which one should you choose for your shower? We have researched everything you need to know. 

Flexstone is an ideal bathroom fixture since it has been UV-stabilized to prevent staining and discoloration. Here are its advantages:

  • Non-porous
  • Mold and mildew-resistant
  • Low-maintenance
  • Can be installed over existing tiles

One disadvantage to consider is that it is not considered a Solid Surface material, which means it can't be sanded to repair minor damages like scratching or scuffing. 

Swanstone, although just as ideal as Flexstone, has different qualities. For instance, it is made of solid surface material, so you can sand it down when necessary. Here are other advantages to consider:

  • High resistance to heat, impact, and chemicals
  • Easy to assemble and install
  • More durable than other shower fixtures
  • Consistent thickness
  • Scratch and crack-resistant

One disadvantage to mull over is that you will need to seal it with a strong and high-quality sealer. Although it is relatively moisture-proof, it needs another layer of protection to be more durable.  

Another material to consider is Onyx, which is a more expensive alternative. Here are its advantages:

  • Aesthetically pleasing because of its natural look
  • Lots of color options
  • Has a long lifespan.

However, despite its qualities, some disadvantages can make you think twice. For instance, it is the most high-maintenance out of the three options. Since it is a natural stone, staining is easy and it can easily get damaged if it is not sealed regularly. 

Bathrooms and shower rooms are spaces in your house you cannot overlook. It's important to choose the right materials so you won't have to go through expensive repairs that also consume time and energy. Keep reading below to learn more about how to choose the best materials for your shower room.
