Who doesn’t want a tiling option that speeds up installation and saves money? That’s exactly what tiling over tiles can do for you, if you do it right.
Doing it right of course is all about knowing when this might be an appropriate option and when it isn't. For instance, when it comes to tiling a wall or floor during a renovation or redesign, if you already have tiles over tiles, you can't just add a third layer on top.
However, if you only have a single layer of tiles, then you could be in luck if they meet the parameters we explain below.

The benefits of tiling over tiles
Here we take a look at the situations and scenarios where it makes sense to tile over tile.
1. Flat and level surface
A properly tiled wall provides a great base to work with, as Stephen Russell from Ashley Cross Tiling explains: “Tiling over tile is one of the best 'fixes', because the original tiling is a flat surface that needs no bonding with primer.”
He continues: “Also, you can see with the original layout that the tiling is running level around the floor and ceiling.”
2. It’s quicker
Tiling over tile is typically a much quicker and easier solution than removing all the original tiles and going back to bare walls. Removing tiles can be a time-consuming task, especially if you are removing them from the wall to the floor.
Russell says, "Also, even if you do remove the tiles, you can rarely tile straight onto a wall." He adds, "It will need to be skimmed or a new board installed, allowing you to consider tiling onto plasterboard." Neither of these options are anywhere near as quick as tiling over tiles.
3. Cost-effective solution
There’s no need to think about buying new or hiring tools to remove the tiles, so you are saving money on these. If you don't have one already, you may need an SDS drill to remove stubborn tiles, for instance.
As mentioned before, when removing tiles, there is a possibility that the tiles will pull away plaster from the wall or create unwanted holes in the floor, meaning both will need to be repaired before you can tile. This will involve purchasing more materials.
The drawbacks to tiling over tiles
Despite the obvious plus points of tiling over tiles, there are some situations where it should be avoided.
1. Poor surface
If the tiles on the wall or floor are of cracked, missing grout and starting to lift of the surface then they will not provide a solid surface which can lead to problems further down the line as Russell reveals: “The original tiling may be not solidly adhered to the wall causing the new tiles to eventually fall off.”
How do you check? “Check the original tiles by tapping them gently with a coin to hear if the tiles have a hollow sound.” If they do you will need to remove the tiles before adding new tiles.
2. Extra weight
Adding another layer of tiles on top of the original tiles will double the weight on the wall or floor, which may cause damage.
Harriet Goodacre, Interiors and tiling expert at Topps Tiles, points out, "It’s important to understand the original substrate, such as plaster or plasterboard." She adds, "These have weight limits that need to be considered when adding an additional layer of tiles, adhesive and grout.”

3. Doubling depth
Doubling the depth of the tiles can lead to issues, as Goodacre shares: "There can also be aesthetic limitations – particularly around door frames, window reveals, shower fittings or where walls are only half tiled – as the added depth can be noticeable, meaning trims can’t always be neatly integrated.”
Also, if adding an extra layer to the floor, will your appliances still fit, especially under-counter appliances?
FAQs
How do I prepare old tiles ready for tiling?
First, make sure none of the tiles is loose, and that the surface is as smooth as possible. Knock off any stray grout or cement, and sand down.
Goodacre adds, "The existing tiles also need to be clean and free of grease or other contaminants, which could affect the bond of the adhesive used for the new tiles. I recommend using sugar soap or a suitable degreaser beforehand."

Should I use a special tile adhesive?
You can use any tile adhesive, but to ensure a long-lasting, strong grip, choose one better suited to the job. Instant grab, non-slip, ready-mixed adhesives such as Everbuild 701 Super Plus and BAL White Star Plus are both good options.
