90% of families make mistakes when tiling the bathroom – did you fall into this trap?

The experience of using a bathroom often lies in the most inconspicuous details. Many people spend a lot of money on renovations, only to have problems with their bathroom later: water accumulation, mold, slipping... These issues could stem from mistakes made during the tiling process. Today, let’s go through the 4 key details you must pay attention to when tiling your bathroom to avoid future problems! 

  1. Poor corner treatment leads to minor bumps turning into "disfigurement" 

The corners, where the walls meet, are at risk of chipping if not properly handled. Common protection methods include corner trims and the "Haitang corner."

  • Corner trim: Convenient and practical, it’s directly embedded during tiling. Low cost and easy to install. 

  • Haitang corner: Requires each corner of the two tiles to be beveled at a 45-degree angle and joined together. It looks more aesthetic, prevents chipping when paired with grout, but has higher construction requirements. 

  1. "Wall-over-floor" technique determines whether your bathroom smells all year round 

Don’t underestimate the joint between the floor and wall tiles. If the floor tiles overlap the wall tiles, water can accumulate in the corner seams, leading to mold and bad smells. The "wall-over-floor" method ensures that water flows into the drain properly, avoiding standing water and mold.

Remember to design the slope based on the location of the drain. The ideal scenario is a height difference of 1-3 cm within 1 meter of the drain. After installation, you can test the slope with a ping pong ball to check if it’s reasonable. 

  1. Don’t tile all the way up to the ceiling, beware of "water curtain caves" in the ceiling 

Many people think that the higher the tiles, the better, but that’s not the case. Bathroom ceilings are often equipped with aluminum ceiling panels filled with wiring and lighting. If you tile all the way to the ceiling, moisture may creep up into the ceiling’s interior, increasing the risk of electric leakage. The correct approach is to tile up to 2-3 cm above the ceiling, which maintains aesthetics and keeps the ceiling dry.

  1. Non-slip floor tiles are useless no matter how expensive 

The bathroom is one of the most accident-prone areas in the home, especially when the floor tiles lack anti-slip properties. It’s recommended to use matte, non-slip tiles, and be sure to design a water barrier between the shower area and dry areas to prevent flooding.

In conclusion: When tiling your bathroom, details make the difference between safety and comfort! It’s better to ensure everything is done right in the early stages than to redo it later.
