Wiping off your vanity countertop is not enough. The bathroom may be your hub of cleanliness, but mould, bacteria and other irritants could well be lurking underneath your tiles, especially if you love long showers. Bathrooms are an area where you get a high concentration of moisture, which can lead to mould, mildew, failing grout, rotting walls — you name it. So everything you put in there — whether a shower or cup surround — should be moisture-resistant. You should always be thinking about how to reduce the amount of condensation in that room. Otherwise, you’re looking at a lot of problems.
