If you're seeing water on the bathroom floor every time someone takes a shower, you're not alone. Shower door leaks are one of the most common calls we get at the shop. The good news? Most leaks come from three or four causes, and most of them are fixable without replacing the whole door.
We've been installing and repairing shower doors in Connecticut for forty years. In that time, we've seen the same handful of problems show up over and over. A shower door that worked fine for ten years can suddenly start leaking, and the cause is usually something small that wore out, shifted, or stopped sealing properly.
This guide walks through the main reasons a shower door leaks, what you can check yourself, and when it makes sense to call a glass contractor. If you're in Connecticut and the leak is getting worse, we offer free on site assessments. But before you call anyone, here's what's probably going on.
The Vinyl Sweep Is Worn Out
The vinyl sweep is the clear strip on the bottom edge of your shower door. Its job is to make contact with the curb or tub and keep water inside. After five to ten years of daily use, vinyl sweeps get brittle, cracked, or compressed. Once they lose their flexibility, they stop sealing.
Check yours by running your finger along the bottom edge. If the vinyl feels hard, stiff, or has visible cracks, it's done. The good news is that vinyl sweeps are one of the cheapest fixes in the shower door world. Most replacement sweeps cost under twenty dollars and snap into place without tools. We carry replacement parts for most standard hardware brands and can swap one out in fifteen minutes.
The Track Has Shifted Out of Alignment
Sliding shower doors run in metal tracks at the top and bottom. Over time, the screws holding those tracks to the wall can loosen. When the track shifts even an eighth of an inch, the door no longer sits flush against the side seal. Water finds the gap and runs out.
You can spot a shifted track by looking at the gap between the door and the side jamb. It should be uniform from top to bottom. If the gap is wider at the top than the bottom, the track is out of plumb. Tightening the mounting screws sometimes fixes it. If the wall behind the track has settled or shifted, the track may need to be re-shimmed or remounted. That's usually a job for a glass contractor.
The Side Seal Failed
The side seal is the strip of vinyl or rubber along the hinge or jamb side of the door. It's what keeps water from running out where the door meets the wall or the fixed glass panel. Side seals fail in two ways. They tear, or they peel away from the glass.
If you've cleaned your shower door aggressively, the seal might be torn or completely missing. If your bathroom gets a lot of humidity, the adhesive holding a stick-on seal might have let go. Either way, side seals are replaceable. Most are inexpensive parts that snap or stick into place. The trick is finding the right size and profile for your specific door brand. We keep common profiles in stock at the shop in Connecticut.
The Wall or Curb Is No Longer Plumb
This one is the trickier diagnosis. Houses settle. Bathroom walls move slightly over decades, especially in older Connecticut homes. If the wall that holds your shower door has shifted out of plumb, the door no longer makes proper contact with the seals. Water leaks through the resulting gap.
To check, hold a level against the wall next to the door. If the bubble is off, the wall has moved. Fixing this is more involved. Sometimes we can shim the door hardware to compensate. Other times, the door needs to be re-cut or replaced to fit the current opening. This is when an on site measurement visit pays off. We can tell you exactly what's needed in a single visit.
Frequently Asked Questions
How much does a shower door repair cost?
Simple fixes like sweep or seal replacement usually run under one hundred dollars. Track realignment costs more. If the door needs replacement, that's a larger job. We give written estimates after an on site visit, free of charge.
Can I replace a shower door seal myself?
Yes, if you can find the right size and profile. Snap-in vinyl sweeps are easy. Side seals can be trickier because brands vary. Bring your old seal to a glass shop and they can usually match it for you.
How long do shower door seals last?
Five to ten years for vinyl sweeps with normal use. Side seals can last longer if they aren't damaged by cleaning. Hard water and harsh cleaners shorten the life of any rubber or vinyl part in a shower.
Should I just replace the whole shower door?
Not unless the glass is damaged or the door is past its useful life. Most leaks are seal or hardware issues that cost a fraction of a full replacement. A glass contractor can tell you which makes sense.
Why is water pooling on the curb instead of running into the shower?
The curb might be sloped the wrong way. This is a tile installation issue, not a shower door problem. Fixing it usually requires re-doing the tile work on the curb itself.
