When it comes to bathroom remodeling, most homeowners expect their new shower or tub to look great and function flawlessly for years. But what happens when that isn’t the case? If you’ve noticed issues like leaking corners, cracked grout, or the bottom of your new bathtub flexing, you may not be dealing with faulty materials; you might be dealing with bad installation!
Below, we break down the most common shower and bathtub installation problems, what causes them, and how to spot mistakes early so they don’t turn into long-term damage.
Common Bathtub Installation Problems Caused by Improper Setup
Most bathtubs are designed to last for decades, but installation errors can shorten their lifespan dramatically.
Flexing, Creaking, or Unstable Bathtub Bases
A common complaint among homeowners is the bottom of the bathtub flexing when stepped on. This movement isn’t just annoying. It’s a sign that the tub wasn’t properly supported during installation.
What causes it:
- Lack of mortar or foam base beneath the tub
- Uneven subfloor that wasn’t corrected beforehand
- Failure to anchor the tub securely to wall studs
When tubs shift or flex under pressure, they’re more likely to crack, leak, or warp over time.
Drainage Issues and Leaks
Another red flag? Slow-draining tubs or pooling water beneath them. Poor alignment between the tub and the drain can cause leaks behind the walls or under the flooring, leading to mold, mildew, and water damage.
Sealant Failures and Water Intrusion
Silicone caulk applied poorly or inconsistently can wear away in high-moisture zones. If water starts getting behind your bathtub, mold and rot can follow. These are avoidable problems with the right prep and follow-through.

Shower Pan Installation Mistakes That Lead to Bigger Problems
Incorrect shower pan installation mistakes are one of the most expensive and frustrating errors a homeowner can face. That’s because the pan is the foundation of your entire shower system. Any fault here can mean full removal and replacement.
Signs of Shower Pan Failure
- Cracking or movement underfoot
- Persistent leaks in nearby walls or ceilings
- Mold or musty odors around the base of the shower
Poor slope, wrong materials, and sloppy sealing are usually to blame. Shower pan failure often takes months to reveal itself, but by then, damage is already extensive.
A professionally installed replacement shower uses quality pans, correct adhesives, and precise leveling to prevent these issues from the start.
What Happens When a Shower Door Is Installed Wrong
A shower door installed wrong may not seem like a major issue, but it can lead to everything from water leaks to safety concerns.
Installation Errors to Watch For:
- Misaligned hinges or sliding tracks
- Gaps that allow water to escape
- Loose screws or wobbly handles
- Uneven mounting that puts stress on glass panels
Shower doors require precise measurements and expert mounting. Otherwise, you could find yourself resealing or replacing components in less than a year. At Rite Window, our installation team has extensive experience identifying and correcting all types of shower door alignment issues.
Other Costly Consequences of Bad Installation
Beyond the obvious cracks and leaks, improper bathtub and shower installation can lead to structural damage, increased utility bills, and even safety hazards.
Here’s what can go wrong:
- Water damage in adjacent rooms: Moisture doesn’t stay put. Once it seeps behind walls, it can travel fast!
- Higher energy bills: Poor sealing and damp insulation reduce HVAC efficiency.
- Resale concerns: Buyers are wary of DIY-looking renovations or patch jobs, so always consider a professional installer first when handling a bathroom remodel.
- Code violations: Unpermitted or sloppy work can prevent home sales or insurance payouts.
A professionally executed tub-to-shower conversion can help prevent many of the most common installation-related issues before they start.
Why So Many of These Issues Are Installer Errors and Not Product Defects
It’s easy to blame the manufacturer when something goes wrong, but many shower and bathtub failures aren’t design flaws; they’re preventable installation errors.
Poor installation work often stems from shortcuts and negligence. Some installers skip crucial leveling steps just to save time, while others fail to follow the manufacturer’s instructions altogether. It’s not uncommon for the wrong type of caulk or adhesive to be used, compromising the seal and longevity of the tub or shower. In the worst cases, installers neglect proper waterproofing behind the walls, leaving your home vulnerable to hidden moisture damage.
These shortcuts might not show immediately, but they almost always lead to problems later. Our post on 7 overlooked bathtub and shower problems covers additional warning signs that something might not be right.
How to Protect Yourself Before Hiring a Contractor
The best way to avoid bathtub installation problems and other mistakes is to hire a contractor who specializes in bathroom remodeling, not a generalist. If you’re planning a remodel, ask specific questions about materials, waterproofing methods, and how errors will be handled.
A few smart steps include:
- Ask about past installation errors: Reputable installers will admit to learning from mistakes.
- Request photos of past work: Not just final shots. Ask for in-progress images.
- Ask who will be performing the work: Confirm that they’re experienced with your specific type of installation..
- Get details on warranty coverage: Understand what is and isn’t protected.
