Why Custom Tile Showers Need to Be Installed Correctly the First Time
A shower is one of the least forgiving spaces in your home to get wrong — skip the waterproofing membrane, get the floor slope wrong, or use the wrong grout at a seam, and you’re looking at water damage inside the wall before you ever see a visible sign of a problem. Older Dayton-area homes especially often have showers that were never properly waterproofed to begin with, which is usually what’s actually causing the mold, soft spots, or musty smell homeowners notice years later.
Cracking grout or caulk at seams
Movement and water penetration at the shower’s weakest points.
Soft spots outside the shower
Water has already made it past the waterproofing layer.
Recurring mold or musty smell
Trapped moisture behind tile from a failed membrane or seam.

Custom Tile Shower Installation in Dayton — What to Expect
A custom shower is a slower, more deliberate job than a backsplash or a floor — and we treat it that way. AGM Tile & Flooring builds showers with a proper waterproofing membrane, correct floor slope toward the drain, and cement board substrate before a single tile goes up, because that’s the part of the job nobody sees but everyone eventually feels if it’s skipped.
This is a bigger, higher-stakes job than a backsplash — which is exactly why we don’t rush the waterproofing and substrate steps to hit a faster timeline. If something we installed doesn’t hold up, we come back and fix it. No shortcuts on the part of the job you can’t see once the tile’s up.
Full membrane systems
Waterproofing membrane on walls and floor with corners and seams treated properly.
Sloped, tested pans
Every pan pitched to the drain so water moves where it should — not into the wall.
Recessed niches & benches
Framed and waterproofed as part of the same install, not tacked on after.
Flexible caulk at seams
Inside corners get caulk, not grout, so movement doesn’t crack your joints.
What Dayton-Area Homeowners Say About Our Custom Tile Shower Installation
“They explained the waterproofing step by step before starting — no leaks, no issues, over a year later.”
“Our old shower had mold behind the wall from a bad install years ago. They caught it, fixed the substrate, and rebuilt it right.”
“Slower process than I expected, but now I understand why — worth the wait for something that won’t need to be redone.”

How Much Does Custom Tile Shower Installation Cost in Dayton?
Shower pricing depends on the size of the space, tile material, and how much custom detail you want — a niche, a bench, and a specialty tile pattern all add time compared to a straightforward wall-and-floor tile job. This is a slower, higher-stakes install than a backsplash or floor, so we give you an exact quote after seeing the space and the substrate condition in person. That quote covers demo, waterproofing, substrate, tile, grout, and fixture reinstall — no surprise costs once the walls are open.

Custom Tile Shower Installation FAQ
How long does a custom tile shower installation take?
Most custom showers take 3–5 days from demo through finished, sealed tile — longer than a backsplash or floor because waterproofing and substrate work can’t be rushed.
How much does custom tile shower installation cost in Dayton?
It depends on shower size, tile material, and details like a niche or bench. We give you an exact quote after seeing the space and substrate condition in person.
How do I know if my shower needs to be redone?
Cracking grout or caulk at corners, soft or discolored walls outside the shower, or a musty smell that keeps returning are the clearest signs of a waterproofing failure.
Do you offer same-day tile shower quotes?
Yes — we typically respond to estimate requests the same day, though the installation itself takes longer given the scope of the work.
Will my new shower leak if the old one did?
Not if it’s waterproofed correctly the first time. A lot of our shower jobs are fixing exactly this problem from a previous install that skipped proper membrane and slope.
What warranty do you provide on tile shower installation?
We stand behind our installation work — if an issue traces back to how we installed it, we come back and fix it at no cost.
Can you add a niche or bench to my custom shower?
Yes — niches and benches are common additions, and we frame and waterproof them as part of the same install.
