Have you ever looked at your dated shower floor and wished for a fresh, modern look? Maybe the grout is stained, the tiles are cracked, or the overall aesthetic is just tired.

The short answer is: sometimes. Whether or not you can tile over a shower floor depends on several factors, including the condition of the existing flooring, the type of tile you’re using, and your DIY skills. This article will delve into the intricacies of this project, providing you with the knowledge and guidance you need to make an informed decision.
Assessing the Existing Shower Floor
Before you even think about breaking out the tile and grout, you need to carefully assess the condition of your current shower floor. Here’s where to start:
Checking for Structural Integrity
First and foremost, you need to ensure that the existing shower floor is structurally sound. This means checking for any signs of cracking, sagging, or movement. If you notice any of these issues, it’s best to consult with a professional contractor. Tiling over a compromised floor can lead to future problems, including leaks and tile failure.
Inspecting the Subfloor
Next, you need to check the subfloor beneath the existing tile. If you have a concrete subfloor, make sure it’s smooth and level. Any unevenness will transfer to the new tile, resulting in a bumpy and uneven finish. Ideally, the subfloor should be within 1/8 inch of level per 10 feet. If there are any significant dips or bumps, you’ll need to level out the subfloor before tiling.

Grout Condition
The condition of the grout also plays a crucial role in determining if tiling over the existing floor is feasible. If the grout is cracked, crumbling, or severely stained, it’s best to remove the existing tile entirely. This will ensure a clean and smooth surface for the new tiles.
Material Compatibility
Lastly, you need to consider the compatibility of the existing tile with the new tile. This is particularly important if you’re using a heavier or denser tile. If the existing tile is thin and fragile, there’s a chance that it could break under the weight of the new tiles.
Can You Tile Over a Shower Floor?
Now that you’ve assessed the condition of your existing shower floor, you can start to determine if tiling over it is a viable option. Here are some key considerations:
A Tile Over Tile Approach
In many cases, tiling over an existing shower floor is a feasible solution. Here are some scenarios where it may be a good option:
- The subfloor is in good condition and level.
- The existing tiles are in good shape, with minimal cracking or damage.
- The existing grout is in good condition, with no cracks or significant staining.
- You are using a similar type of tile, or the new tiles are not significantly heavier than the existing tiles.
When to Reconsider Tile Over Tile
However, tiling over an existing shower floor isn’t always the best solution. Here are some situations where it’s recommended to remove the existing tile:
- The subfloor is uneven, cracked, or damaged.
- The existing tile is cracked, chipped, or heavily stained, making it difficult to achieve a smooth and even surface for the new tiles.
- The existing grout is cracked, crumbling, or severely stained.
- The existing tiles are thin and fragile, making them susceptible to breakage under the weight of the new tiles.
- You’re using a significantly heavier or denser tile than the existing tiles.
Steps Involved in Tiling Over a Shower Floor
If you’ve decided to move forward with tiling over your existing shower floor, here’s a general overview of the steps involved:
Preparation is Key
Start by removing any existing caulk or sealant around the perimeter of the shower. This will ensure a clean and smooth surface for the new tile.
Cleaning and Bonding
Thoroughly clean the existing tile and grout with a strong cleaner. This will remove any dirt, grime, or residue that could interfere with the adhesion of the new tile. Once the surface is dry, apply a bonding agent to create a strong bond between the new tile and the existing surface.
Applying Mortar and Tiling
Apply a generous layer of thin-set mortar to the shower floor. Be sure to spread it evenly and make sure there are no air pockets. You can use a notched trowel to ensure even distribution. Then, start laying your tile, making sure they’re level and evenly spaced. Remember to use spacers to create a consistent grout line.
Grouting and Finishing Touches
Once the mortar has set, you can start grouting. Apply grout to the spaces between the tiles, making sure to fill them completely. Wipe away any excess grout with a damp sponge. Finally, apply a sealant to the grout to protect it from moisture and stains.
Expert Tips for Tiling Over a Shower Floor
Here are some expert tips to help make your shower floor tiling project a success:
Choose the Right Tile
When choosing your new tile, consider the size and weight of the existing tiles. You don’t want to use a tile that is significantly heavier, as this could put stress on the existing subfloor and create problems in the future. Opt for a tile that is similar in size and weight to the existing tile or slightly thinner.
Use a Bonded Mortar
To ensure a strong bond between the new tile and the existing floor, use a bonded mortar. These mortars are designed for use on existing tile, providing extra strength and durability.
Use a Level
During the tiling process, use a level to ensure that all the tiles are positioned correctly and that the shower floor is level. This will prevent unevenness and ensure a smooth and even finish.
Consider Hiring a Professional
If you’re not comfortable with the tiling process, or if your shower floor has structural issues, it’s best to hire a professional contractor. A professional will be able to assess the condition of your shower floor, provide expert advice, and complete the job correctly and efficiently.
