The Detail That Decides Whether Your Bathroom Floor Stays Dry

A shower door that leaks doesn’t usually leak through the glass. It leaks around it, at the seal, the sweep, or a frame that was never quite plumb to begin with. Comprehensive Construction Services (CCS) installs tub and shower doors for residential remodeling projects and new bathroom construction throughout Northern California. It’s a small-looking job on paper, one piece of glass and a handful of hardware, but the tolerances involved are tighter than almost anything else we install, since a shower door has to seal against a curb and walls that are rarely perfectly square.

Framed, Semi-Frameless, or Fully Frameless

We’ll say this plainly even though frameless is the more expensive, more requested option: if a shower opening is noticeably out of square, a frameless door can end up with an uneven gap along one edge that no amount of careful installation fully hides. We’ll measure and tell you honestly which option actually suits your specific shower:

Framed — an aluminum frame around the full perimeter, the most budget-friendly and forgiving of an out-of-square opening
Semi-Frameless — heavier glass with minimal framing, usually just at the hinge side, splitting the difference on cost and look
Fully Frameless — thick tempered glass with no surrounding frame, the premium option, and the least forgiving of an imperfect opening

What Actually Keeps Water Inside the Shower

That gap between looking fine and actually performing is exactly why we measure every opening carefully before recommending a door style, rather than letting a client pick purely off a showroom photo:

Sweep seals at the bottom of the door, the first line of defense against water escaping under the glass
Proper door swing direction and clearance relative to the curb height
Header and jamb alignment set plumb and level, not just eyeballed against an uneven wall
Silicone sealing at every glass-to-wall and glass-to-curb junction
