Common Causes of Bathroom Floor Tile Deterioration
1. Lack of Waterproofing Before Tiling
Many contractors skip proper waterproofing or apply only a thin, ineffective layer. When moisture seeps from below, it quickly weakens the tile adhesive, causing the tiles to loosen and the floor to bubble over time.
2. Tiling on a Damp or Uneven Surface
If tiles are installed before the screed is fully dry or on an uneven base, the floor may later sink in certain areas. This results in cracked tiles, chipped corners, or a hollow sound when walked on—reducing both durability and aesthetics.
3. Using Improper Tile Adhesive
Bathroom tile adhesive must be water- and moisture-resistant. However, some contractors use cheap or incorrect adhesives, or mix them improperly. This weakens adhesion and can cause tiles to peel off within a few months.
4. Uneven or Incomplete Grouting
If tile joints are not properly filled or done unevenly, or if poor-quality grout is used, the lines will crack easily under moisture and temperature changes. This allows water to seep through and damage the subfloor structure.
5. Improper Sealing at Junctions
Areas such as floor drains, wall corners, and baseboards are often overlooked or poorly sealed during installation. These weak spots are highly susceptible to leaks, which can cause damage even if the tile surface appears intact.
Bathroom Tile Replacement Services – KIONLE
Bathroom tiles can become loose, cracked, or discolored over time, affecting both appearance and safety. These issues increase the risk of water leakage and slippery surfaces. To address them effectively, KIONLE offers at-home waterproof tile replacement services, completed quickly and without disrupting your daily routine.
Before removing the old tiles, we conduct a thorough inspection to assess the condition and identify underlying causes—such as water damage, subsidence, or structural cracks. Based on the findings, KIONLE will recommend the most suitable solution: full floor replacement, localized repairs, or complete re-waterproofing from the base.

Bathroom Floor Tiling Process – KIONLE
KIONLE’s toilet refresh process includes 6 steps:
Step 1: Site Inspection
KIONLE visits the property to assess whether the bathroom floor is affected by water damage, cracks, or subsidence. We also check water drainage slope, pipe collars, and other weak points that could lead to future leakage.
Step 2: Removing Old Tiles
Old tiles are carefully removed to avoid damaging the concrete subfloor. The surface is then cleaned, cracks are repaired, and the area is leveled in preparation for waterproofing and re-tiling.
Step 3: Waterproofing
Depending on the condition, KIONLE applies cement-based waterproof coatings, heat-applied membranes, or two-component waterproof mortars. Critical areas such as pipe collars, wall corners, and expansion joints are treated thoroughly to prevent future water seepage.
Step 4: Creating a Proper Drainage Slope
After waterproofing, a new mortar bed is applied with an accurate slope toward the floor drain. This ensures that water flows correctly and doesn’t pool, reducing the risk of future seepage into the subfloor.
Step 5: Laying New Tiles and Sealing Grout Lines
Tiles are measured, cut, and laid precisely using moisture-resistant adhesive. Once tiling is complete, waterproof grout is applied to seal the joints, preventing water from penetrating between the tiles.
Step 6: Final Check & Handover
The entire area is cleaned, with excess adhesive, tile dust, and material odors removed. KIONLE conducts a detailed inspection with the client, checking all completed work and providing guidance on post-installation care and maintenance.
