Gluing tiles to tiles advantages and disadvantages

Laying tiles on tiles is an inexpensive alternative. However, it is not always the best method.

Difficulty: Medium | Costs: approx. 100 - 300 euros | Workload: approx. 1 day

Laying tile on tile is gaining popularity as it saves time, money and effort.

However, despite these advantages, there are also some disadvantages that need to be considered. In this article, we'll take a closer look at the downsides of installing tile on tile so you can make an informed decision.

1. What are the advantages or disadvantages of gluing or laying tiles on tiles?

Advantages Disadvantages
1 Cost savings Increased ground level
2 time saving bumps and instability
3 protection of the environment difficulty in alignment
4 Easier renovation Unstable connections
5 Less rubble and waste liability issues
6 No need for demolition work Insufficient adhesion
7 environmental friendliness detaching the tiles
8th Less noise pollution aesthetic disadvantages
9 Limited theme options
10 joint problems

2. Reasons for laying tiles on tiles

2.1 How much money can be saved when laying tiles on tiles?

One of the main reasons people choose to install tile on tile is the potential cost savings. Since the old tile surface does not have to be removed, there are less labor costs and disposal costs. On average you save up to 50% of the costs.

2.2 Time Saving

Another motivation is the time saving. Removing the old tiles and preparing the surface for new tiles can be time consuming. By gluing tiles directly onto the existing tiles, this process can be significantly shortened.

2.3 Protection of the environment

Laying tile on tile is also more environmentally friendly. By avoiding demolition and disposal work, fewer resources are used and waste is reduced.

3. What are the disadvantages of gluing tiles to tiles?

Despite the advantages mentioned, there are also some disadvantages that must be considered when deciding whether to lay tile on tile.

3.1 Elevated Ground Level

Laying tiles on top of tiles will result in increased floor height. This can result in doors having to be shortened or thresholds adjusted.

According to the floor pros: In some cases, this can cause ceiling height issues, especially in older buildings with low ceilings.

3.2 Bumps and Instability

3.2.1 Alignment difficulties

Laying tile on tile can cause alignment difficulties, especially if the underlying tiles are uneven or cracked. These bumps can cause the new tiles to be misaligned, resulting in an uneven and unsightly finish.

3.2.2 Unstable Connections

Another challenge is that the connections between the new and old tiles may not be strong enough. This can cause the new tiles to loosen or lift, causing further problems.

4. Are there liability issues?

Insufficient adhesion

One of the biggest challenges when laying tile on tile is adhesion. There may be insufficient adhesion between the two layers of tile, resulting in an unsafe and potentially dangerous surface.

detaching the tiles

Another adhesion problem is that the tiles can delaminate over time, especially when exposed to moisture, severe temperature changes, or mechanical stress. This can result in surface damage and costly repairs.

aesthetic disadvantages

Limited theme options

One downside to laying tile on tile is that design options can be limited. As the new tiles are laid on top of the existing tiles, it may not be possible to use all the patterns or colors requested.

joint problems

Joint problems can also occur when gluing tiles to tiles. The new joints can mix with the old joints, resulting in an unclean and unaesthetic appearance.


Although there are some advantages to laying tile on tile such as time and cost savings and environmental friendliness, there are also a number of disadvantages that need to be considered. These disadvantages include increased ground clearance, bumps, instability, adhesion issues, and aesthetic limitations. Before you decide to use this method, you should carefully weigh these disadvantages and see if it is suitable for your project.


  1. Can I glue tile to tile if the underlying tile is damaged?

    It is not recommended to lay tiles on top of damaged tiles as this can lead to adhesion problems and instability.

    In particular, you should remove broken floor tiles .
  2. How can I ensure that the adhesion between the layers of tiles is sufficient?

    To ensure adequate adhesion, you should thoroughly clean and dust off the surface, use suitable tile adhesive and mortar and follow the manufacturer's instructions exactly.

  3. Is laying tile on tile suitable for bathrooms?

    Laying tile on tile can work in bathrooms, but you should take extra care with adhesion and use waterproof materials to avoid moisture problems.
  4. Can I lay tiles on top of tiles if the underlying tiles are made of a different material?

    Laying tiles on top of tiles made of different materials is possible, but you will need to ensure the sub-floor is flat and stable, and possibly use a suitable adhesion promoter.
  5. How do I care for my newly laid tiles on tiles?

    The maintenance of tiles on tiles is similar to that of conventionally laid tiles. Make sure to clean the tiles regularly , using appropriate detergents and avoiding harsh chemicals that could damage the adhesion or the material.
