Can You Put Tile Over Tile in a Shower Hassle-Free
Looking to update your shower tiles but worried about the mess of removing the old ones? I get it – tearing out existing tiles can be a huge job.
Many homeowners face the same problem when they want to give their shower a fresh look.
Good news! You can actually install new tiles right over your existing shower tiles. I’ll share the exact steps that have worked for me and many others. Plus, I’ll help you figure out if this method will work in your shower.
In this post, I’ll walk you through how to check if your shower is suitable for tile-over-tile installation, what materials you’ll need, and the steps to do it right.
An Overview of Tiling Over Existing Shower Tiles
Think of tiling over existing tiles like putting on a new coat over an old one. It’s a method I’ve seen work really well when done properly. When you put new tiles on top of old ones, you’re basically creating an extra layer in your shower.
I want you to know that this isn’t just a quick fix – it’s a real solution that can save you time and money. Instead of spending days breaking out old tiles and risking damage to your shower walls, you can build right on top of what’s already there.
What makes this method work? It’s all about proper preparation. The existing tiles need to be firmly attached to the wall – no wiggling or loose pieces allowed! Those old tiles will become the foundation for your new ones, so they need to be solid.
Let me share something important from my experience: not every shower is right for this approach. Your wall needs to be strong enough to handle the weight of two layers of tiles.
Plus, those old tiles must be in decent shape – no mold, no major cracks, and definitely no water damage behind them.
Before you start picking out your new tiles, we’ll need to check a few things:
- How strong your walls are
- The condition of your current tiles
- Any height or space restrictions in your shower area
- Whether your old tiles have a surface that new ones can stick to
What I like best about this method is that it lets you update your bathroom without turning it into a construction zone.
But remember, checking these details first will ensure your new shower tiles look great and last for years.

- Wait one hour between coats
- Let final coat dry overnight
3. Prepare the Drain

Can You Put Tile Over Tile in a Shower
Yes, You Can!
But Check These Things First: The success of tiling over existing tiles depends on a few key factors:
- Your old tiles must be firmly attached
- The wall structure needs to support extra weight
- No water damage should be present
- The surface must be clean and stable
How It Works
1. Surface Check
- Old tiles need good bonding
- No cracks or loose pieces
- Walls must be dry and solid
2. Bond Creation
- Special primers help new tiles stick
- Modified thin-set adds extra grip
- Both layers work together
3. Weight Management
- Walls carry about 7-8 pounds more per square foot
- Most bathroom walls can handle this
- Framing must be in good shape
Why It Can Work
- Old tiles provide a solid base
- Modern bonding materials are strong
- Installation is often faster than removal
- Less mess and work than demolition
When It Won’t Work
- If old tiles move or sound hollow
- When there’s water damage
- If drain height can’t be adjusted
- When the wall structure is weak
An Approximate Budget Analysis
I’ll break this down into essential items and their typical price ranges based on a standard shower size (about 32″ x 32″):
| Category | Item | Cost Range |
|---|---|---|
| Basic Materials | Bonding Primer | $30 – $45 per gallon |
| New Shower Tiles | $3 – $15 per sq. ft. | |
| Modified Thinset Mortar | $25 – $35 per 50lb bag | |
| Grout with Additive | $30 – $45 | |
| Silicone Caulk | $8 – $12 | |
| Drain Cover and Parts | $15 – $30 | |
| Tools | Utility Knife | $5 – $10 |
| Notched Trowel | $10 – $15 | |
| Grout Float | $8 – $12 | |
| Sponges and Cleaning Supplies | $15 – $25 | |
| Shop Vacuum (if needed) | $40 – $70 | |
| Total Cost Range | Low End (basic tiles, tools) | $275 – $350 |
| Mid-range (better quality tiles) | $400 – $600 | |
| High-End (premium tiles) | $700 – $900 |
Money-Saving Tips
- Use tools you already own
- Look for tile sales at local stores
- Buy a bit extra tile (10% more) to avoid running short
- Consider buying materials in bulk if doing multiple projects
Remember: These prices can change based on where you live and current market conditions. It’s smart to check local stores for the most current prices.
How to Ensure Proper Waterproofing
1. Water Protection Starts from Below
First, you need to check your existing tiles. I always tell my clients to look for these signs:
- No loose or hollow-sounding tiles when tapped
- No water stains on the floor below the shower
- No mold or mildew between tiles
- Solid, intact grout lines
2. Checking the Current Setup
Your old tile setup needs to have proper waterproofing already in place. Here’s what to look for:
- A working shower pan liner under the base tiles
- Waterproof backing behind wall tiles
- Good drainage with no standing water
- Working drain seals
3. Making It Extra Safe
Even with good existing waterproofing, I take these steps:
- Seal all seams where walls meet
- Put extra attention around the drain area
- Make sure the drain is at the right height with new tiles
- Use waterproof grout
- Add 100% silicone in all corners and edges
4. Important Daily Checks
Keep an eye out for:
- Water pooling anywhere
- Gaps in seals or caulking
- Cracks in grout lines
- Slow drainage
If you see water damage below your shower or feel spongy floors, stop and call a pro. That means a leak already needs fixing before adding new tiles.
Best Techniques to Deal with Increased Thickness
| Category | Action | Details |
|---|---|---|
| Dealing with the Drain | Measure Tile Thickness | Ensure accurate measurement of new tile thickness. |
| Use Drain Extension Ring | Raise the drain height for proper alignment. | |
| Check Drain Height | Ensure the drain sits slightly lower than the tile surface. | |
| Test Water Flow | Ensure proper drainage post-installation. | |
| Door Clearance Fixes | Check Door Functionality | Ensure the door opens and closes properly. |
| Add Longer Hinges | If needed, to ensure smooth door movement. | |
| Trim the Bottom of the Door | If necessary, for clearance with new tile height. | |
| Consider Sliding Door | If door clearance issues persist, consider a sliding door. | |
| Transitions Matter | Create Smooth Slopes at Edges | Ensure seamless transitions between surfaces. |
| Use Transition Strips | For different heights between surfaces. | |
| Avoid Trip Hazards | Ensure transitions are safe and smooth. | |
| Seal Edges Well | Prevent water leakage at the edges. | |
| Smart Planning Tips | Choose Thinner Tiles | To minimize height change when possible. |
| Use Tile-Over-Tile Thin-Set | Special thin-set for tile over existing tiles. | |
| Align Grout Lines with Old Tiles | Maintain consistent grout lines for aesthetic unity. | |
| Leave Gaps for Expansion | Small gaps at edges to allow for material expansion. | |
| Height Issues to Watch | Total Height Under Shower Head | Ensure the height is comfortable for use. |
| Shower Control Accessibility | Ensure easy access to shower controls. | |
| Soap Dish & Shelf Heights | Install at a comfortable, accessible height. | |
| Corner Edges at Wall Junctions | Watch for any potential height inconsistencies. |
