Water getting under your shower floor or walls usually means the waterproofing has failed at key connection points, like the curb, the wall-to-floor seam, or the bench. In many cases you do not have to replace everything, but ignoring it will cause damage that becomes far more expensive over time.
A homeowner in New Orleans, LA recently reached out to us about their master bathroom shower. The system looked fine on the surface, but a closer look revealed unsealed seams at the curb, a bench that was not properly tied into the threshold, and water silently working its way under the floor. This is more common than most people realize.
At Sela Renovations LLC, we walk through situations like this regularly. Here is what you actually need to know.
How does water get under a shower floor in the first place?
Water finds its way underneath when the joints between your curb, walls, and floor are not properly sealed. These connection points are the most vulnerable spots in any shower. Silicone caulk is typically what holds them together, and over time it dries out, shrinks, or simply was never applied correctly to begin with.
What makes this tricky is that the pan, the walls, and the curb are often separate components that need to be tied together with waterproofing. If any one of those connections fails, water has a path straight down into your subfloor.
- The curb is not bonded to the floor or wall
- The bench sits loose against the threshold with no seal
- Silicone is the only barrier, and it has dried out or cracked
- Water splashing toward corners has nowhere to drain properly
Does a leaking shower always mean you have to gut everything?
Not always, but the honest answer depends on how far the water has traveled and how the original shower was built. If the structure underneath is still sound and the waterproofing failure is limited to the seams, targeted repairs can work. But if water has been sitting under there for a long time, you may already have damage you cannot see.
We always check the slope of the pan first. A good slope means water is draining toward the center rather than pooling at the edges. If that slope is intact, you have more options. If it is not, a full tear-out is usually the smarter path.
Partial repairs also get complicated when the existing components are mismatched or were installed incorrectly at the start. In those cases, trying to patch things together costs more in the long run than starting fresh. Our bathroom remodeling services cover everything from targeted repairs to complete shower rebuilds, depending on what actually makes sense for your situation.
What are the warning signs that the damage is getting worse?
The biggest red flag is any visible gap, movement, or softness at the seams where your curb, walls, and floor meet. By the time you can see or feel the problem, water has usually already been working underneath for a while.
- The curb feels loose or shifts when you press on it
- Grout or caulk lines are cracking or missing at the base of the walls
- You notice soft spots in the floor near the shower
- There is a musty smell even after cleaning
- Your shower pan is no longer sloping cleanly toward the drain
If you are seeing any of these, do not wait. The longer water sits under a shower, the more it spreads into the subfloor and surrounding framing.
Frequently Asked Questions
Can I just re-caulk the seams and call it fixed?
Re-caulking helps only if the waterproofing underneath is still solid and the water has not already breached the structure. If the curb is not properly bonded or the wall-to-floor connection was never fully sealed, new caulk on top will not solve the problem. It needs to be addressed from the base up.
Is it cheaper to repair the shower or replace it completely?
Up front, repairs are often less expensive. Over time, a compromised shower that keeps allowing water in will cost more in structural repairs than a proper replacement would have. We always give homeowners both options with clear reasoning so they can decide what fits their goals and budget.
How do I know if the damage has already spread beyond the shower?
Soft or spongy flooring near the shower, discoloration on the ceiling below a second-floor bathroom, or a persistent musty odor are all signs the water has traveled. A hands-on inspection is the only way to know for certain how far it has gone.
