The look is obvious. The differences that decide it are what is behind the tile, how square the opening is, and how much water you want kept in.
Frameless if the bathroom was designed around the shower and the walls can carry the hardware. Framed if the priority is a watertight, low-cost enclosure that hides an out-of-square opening, or it is a tub. Semi-frameless if you want most of the look for less. The difference that decides it is not the look — it is what is behind the tile and how square the opening is.
| Feature | Framed | Semi-Frameless | Frameless |
|---|---|---|---|
| Glass thickness | 3/16″ – 1/4″ | 1/4″ | 3/8″ or 1/2″ tempered |
| What holds it | Aluminum frame on every edge | Frame on the fixed panels; door edge exposed | Hinges, clips, a header or nothing |
| Look | Visible metal outline | Mostly glass, some metal | Glass only |
| Water containment | Best: frame and sweeps seal every edge | Good | Good with correct sweeps and seals; not watertight by design |
| Cleaning | Frame channels trap soap scum | Some channels | Nothing to trap; wipe and squeegee |
| Fits an out-of-square opening | Frame hides variation | Partly | Glass is cut to the exact opening; measured after tile |
| Hardware weight on the wall | Light | Medium | Heavy: 3/8″ door needs solid backing behind the tile |
| Typical width of a swing door | Up to ~30″ | Up to ~32″ | Up to ~36″ on 1/2″ glass with the right hinges |
| Relative cost | Lowest | Middle | Highest |
| Where it suits | Rentals, budget remodels, tubs | Most family bathrooms | Renovated bathrooms where the shower is the feature |
A frameless enclosure is 3/8-inch or 1/2-inch tempered glass held by hinges, clips and sometimes a header bar, with no frame around the glass edges. The glass carries its own weight and stiffness, which is why it has to be thick. A framed enclosure uses thin glass because the aluminum frame does the structural work; the glass is a filler in a metal box.
Two things follow. First, a frameless door is heavy — a 30-by-72-inch 3/8-inch tempered lite weighs about 75 pounds — and the hinges bolt through the tile into whatever is behind it. If that is drywall with no blocking, the door will sag within a year. We ask what is in the wall before we quote. Second, frameless glass is cut to the exact opening, so it is measured after the tile is on and the opening is final; a framed enclosure can be ordered from rough dimensions because the frame absorbs the variation.
Framed enclosures are the most watertight, because every edge has a frame and a sweep. Frameless enclosures are not watertight by design; they rely on a bottom sweep, clear vinyl seals at the hinge and strike, a door that closes against the fixed panel, and a shower head that points away from the door. Done properly, a frameless shower keeps the floor dry in normal use. Done badly — door hinged on the wrong side, no seals, a rain head aimed at the glass — it leaks, and no amount of caulk fixes a design problem. We hinge the door away from the shower head and specify the seals on every quote.
New York bathrooms are rarely square, especially in prewar buildings. A framed enclosure hides an eighth of an inch of variation inside its channels. A frameless enclosure cannot: the glass is cut to the wall as it is, and if the wall is out of plumb by a quarter inch top to bottom, the glass is cut with that taper and the gap is filled by the seal. This is fine up to about 3/8 of an inch; beyond that the enclosure looks wrong and the semi-frameless or framed option is the honest recommendation. We measure with a laser after tile and tell you which you have.
Frameless hardware is the visible design element: hinges, clips, pulls and header in chrome, brushed nickel, matte black or brass. Framed enclosures have one finish on the frame. On any thick glass the green tint of standard glass shows at the edge and in the reflection; low-iron glass removes it and is worth specifying on a frameless enclosure with white tile. A hydrophobic coating applied in the shop before delivery cuts water spotting and is the single most useful upgrade on any enclosure.
They are not watertight by design, but a properly specified one — bottom sweep, hinge and strike seals, door hinged away from the shower head — keeps the floor dry in normal use. Framed enclosures seal every edge and are the more watertight option.
3/8 inch as standard, 1/2 inch for wide doors or a heavier look. Both are tempered safety glass. Framed enclosures use 3/16 to 1/4 inch because the frame carries the load.
Only if there is blocking behind the tile where the hinges land. A 3/8-inch door weighs 60 to 80 pounds; drywall alone will not hold it. We ask what is behind the wall before quoting, and a semi-frameless or header-supported design is the answer where there is no backing.
After the tile is finished and the opening is final, for frameless. Framed enclosures can be ordered from rough dimensions because the frame absorbs small variation.
Framed, then semi-frameless, then frameless. The glass thickness and the hardware drive the difference. We quote after measuring rather than publish per-enclosure prices, because the opening decides most of the cost.
