My frameless shower screen leaks water onto the bathroom floor — how is it sealed properly?
Water escapes from my frameless glass shower screen onto the bathroom floor every time we shower — pooling outside the enclosure. It's starting to worry me for the floor and the door.
- Is this a sealing / installation problem?
- What actually seals a frameless screen — the plastic strips, the bottom gap, the silicone?
- Can it be fixed, or does the screen need redoing?
Trying to stop the leak before it damages anything. Frameless glass looks great but clearly needs sealing right — what's supposed to be there, and what's likely missing or failed?

Short answer: a frameless shower screen leaking onto the floor is almost always a sealing detail that's missing, worn, or was never fitted right — not the glass itself. Frameless screens rely on clear plastic/PVC SEAL STRIPS (on the door edges and bottom), the correct small gap and fall, and silicone at the right joints (and crucially NOT at the wrong ones). Most leaks are a perished/missing seal strip or bad silicone, and they're usually fixable without replacing the glass.
What seals a frameless screen (what should be there): - Seal strips — clear PVC strips that clip to the bottom of the door (a fin/wiper that meets the floor/tray) and the vertical edges (to close the door-to-fixed-panel and hinge gaps). These wear, harden or fall off — the #1 cause of a floor leak. - The gap & fall — a frameless screen needs the floor to fall toward the drain and the screen positioned so water runs inward. If the floor falls the wrong way or the screen sits wrong, water escapes no matter the seals. - Silicone — in the right places only. Silicone seals the screen-to-wall and screen-to-tray junctions. But you should NOT silicone the whole bottom solid in a way that traps water on the wrong side — done wrong, silicone makes leaks worse or traps water. The detailing matters.
Common causes of your leak: - Worn/missing seal strips (easy, cheap fix — replace the strips). - Failed/incorrect silicone at the wall/tray junction. - Door not aligned so it doesn't close against its seal. - Floor fall/threshold sending water outward (harder — a design/install issue).
Fix: usually new seal strips + re-doing the silicone correctly stops it — no new glass needed. If it's the floor fall/threshold, that's a bigger job. Get an aluminium and glass specialist to re-seal it properly rather than smearing more silicone and hoping. Anyone fixed a shower leak with just new seal strips?
Mine was exactly this — water on the floor after every shower, and it was just the little clear seal strip along the bottom of the door that had perished and half fallen off. New strips and it stopped. People assume a leaking frameless screen means a big glass job, but the seals are consumables that wear out and are cheap to replace. Worth checking the strips and the door alignment before anyone talks you into re-doing the whole screen. The silicone-in-the-wrong-place warning is real too — a previous "fix" had siliconed mine solid and trapped water.
Renter version: ours leaked and it was the seal strip plus the door not quite closing flush, so water ran out the gap. Cheap to sort once someone who knew what they were doing looked at it rather than just adding silicone. Good to know what's actually supposed to be sealing it — the strips and the correct silicone joints — so I could tell the difference between a proper fix and someone just gunging it up. Frameless looks great but the little seals clearly do the real work.
