In many parts of the home, choosing flooring mainly comes down to appearance. You want your living room, dining room, bedroom, or office flooring to look great; performance, while important, is second. With bathrooms, the playbook changes.
When choosing bathroom flooring, consider how it will perform under stress. And the stress event in this case involves water, lots of it. Water is so prevalent in bathrooms that it is an expectation, not an anomaly. Water is everywhere: on the walls, ceiling, and the floor. Moisture will quickly ruin the wrong flooring. To make matters even more difficult, you eventually have to pull those other factors into the dialogue. If moisture were the only factor, sheet vinyl or ceramic tile would likely win every time. But these additional factors, like durability, appearance, cost, and ease of installation, need to be considered, as well.
