A stock mirror fits the box it shipped in. Nothing else. A custom mirror fits your wall. Your vanity. Your outlets. The way light crosses the room at seven in the morning, when you actually need to see your face.
We quote mirror work all over Chicagoland. Same handful of questions on nearly every job. Where is it going? How thick does the glass need to be? What happens at the edges. Does it need safety backing? And who is handling the light.
Custom sizing is the whole point. Cut glass solves outlet placement. It solves corners that were never square. It covers the awkward wall run a stock rectangle leaves half-finished.
Thickness follows span. Thin glass behind a frame on a small piece is fine. Big vanity mirrors, gym walls, unframed installs? Heavier glass, so the panel stays flat.
Safety backing belongs anywhere a mirror can get hit. Gyms, studios, stairwells, kids' rooms, commercial corridors. You know the rooms.
Edge finish is a look and a safety detail at once. Polished, beveled, frosted. Each reads differently in a room. All of them take the raw cut edge off the glass.
Lighting gets planned before fabrication. Not after. LED and sconce decisions change the size of the glass and where wiring has to land.
Mirrors get quoted after measurement. Size and thickness move the number. So do edge work, backing, shape, and how it mounts. Every project gets its own price.
Most rooms were not built to catalog dimensions. A double vanity leaves a run of wall no standard mirror covers cleanly. A gym wall has a light switch sitting three inches into the space you wanted. A powder room has a sloped ceiling. Or plaster that wanders half an inch out of plumb across six feet. We see all three in the same week.
Cutting to size fixes it at the source. We measure. We cut to the opening you actually have. Then we detail the edges and the mounting to suit that wall. Cutouts for outlets, switches, and sconces get made in the shop. Not improvised on a ladder.
The design argument is just as real. One big piece of glass reads calmer than two mismatched mirrors with a gap between them. It throws daylight deeper into the room too. In our custom mirrors work, the single-panel approach is what most homeowners land on once they see the wall taped out.
You look at the vanity mirror every day. It earns the most decisions. Run one continuous piece across a double vanity, or hang a matched pair, one over each sink. A single piece looks more architectural and hides the wall behind it. A pair gives each person a defined zone. It also plays nicely with a sconce hung between them.
Framed, frameless, float-framed. All three work here. Frameless with a polished or beveled edge suits a modern bath. A framed mirror layers into a traditional room more easily, especially where the trim is heavy and painted.
Gym mirrors are a different animal. They are large. They live in a room where heavy things get dropped. And the reflection has to stay true across the whole wall, or form checks are worthless.
So: flat mounting on a wall that is genuinely flat. Glass heavy enough that it does not wave. Safety backing behind the panel, always.
Home gyms usually get one wall of panels butted together. Studios and training floors run longer walls. Those need a plan for outlets, baseboard, and equipment clearance before anything gets cut. Same conversation either way, and it is the one we have on our gym and large-format mirror installations.
A wall mirror changes the room. Checking your reflection is almost a side effect. Put one behind a dining table, along a narrow hallway, or opposite a window. It doubles the apparent depth. It pushes daylight around corners it would never reach on its own.
Full-wall installs need layout work up front. Panel seams. Ceiling lines. Switch plates. All of it gets worked out before the glass is cut. A slight tilt in a wall is invisible until you hang a mirror this size on it. Then it is the only thing anyone sees. Shimming and mounting methods matter as much as the glass spec.
An LED mirror carries its own light source. Usually a backlit halo behind the panel, sometimes an edge-lit band around the perimeter. The payoff is even light on the face with no shadows. A sconce on one side alone never quite delivers that.
The cost is planning. An LED mirror needs power at the right height. It needs a switch or dimmer decision. Neither one is something to sort out after the tile goes up. If the electrical is already set, we work to it. If the bath is still torn open, get the mirror size to your electrician early.
Not every mirror is a rectangle. Arched, round, oval, scalloped, diamond. We cut all of them to order. Antique or smoked glass gives a warmer, softer reflection on pieces that are more feature than function. Shaped mirrors usually end up as the focal point of a hallway, an entry, or a retail interior. Fine for that. Less fine as the mirror you shave in front of.
Mirror glass comes in a few standard thicknesses. The right one follows size and application. Not budget.
Thinner glass is fine on small framed pieces. The frame carries the load and the span is short. It is lighter, cheaper, and easier to hang.
Heavier glass is the answer for anything large or unframed. It holds flat across a long span, so the reflection stays true. It also resists the flex that makes a big mirror look wavy near the edges. Vanity mirrors over a double sink belong in that category. So do gym walls and full-wall installs.
Ask about thickness any time a quote comes in surprisingly low on a large mirror. Thin glass on a wide span is the most common corner cut in this trade. You can spot it from across the room.
The edge of a raw cut mirror is sharp, and it looks unfinished. Every custom mirror should leave the shop with its edges worked. The finish you pick sets the tone of the piece.
Ground and polished to a clean line. Default for modern frameless installs. Reads almost invisible on the wall.
An angled border cut around the perimeter. It catches light and throws a soft prismatic line along the glass. A beveled frameless mirror picks up some of the presence of a framed one. That is why it suits formal rooms.
A satin-etched band that diffuses light and softens the boundary. It hides fingerprints along the edge. Looks right in spa-style bathrooms.
Metal, wood, or painted frame around the glass. Framing lets the mirror match cabinetry or trim. It is also the easiest way to make a large mirror feel like furniture instead of a glass panel. Our glass hardware options page covers the finishes that carry across mirror and shower projects in the same room.
Safety backing is a film on the back of the mirror. If the glass breaks, the film holds it together. It does nothing to the reflection. What it changes is what ends up on the floor after an impact.
Put it anywhere a mirror can get hit. Anywhere people crowd close to the glass, too. Home gyms and fitness studios come first, since dropped weights and swung equipment are just normal Tuesday there. Then stairwells, kids' rooms, dance studios, hallways, commercial corridors.
On most residential vanity mirrors it is optional. On gym walls we treat it as standard. Any commercial install should get checked against local code before we cut anything.
Sizing is where most stock mirror purchases go sideways. A few rules we use on site:
The mirror relates to the vanity below it. Not to the wall. Keep the glass slightly narrower than the counter, or run it the full counter width for a built-in look. Both work. What never works is a mirror wider than the cabinet with no wall detail to justify it.
Center the mirror on the sightline of the people using it. Then check the top edge against any sconce or ceiling detail. In a shared bath, split the difference between users. Do not center on the tallest person in the house.
Panels usually start above the baseboard. They run up to a height that captures a full standing reflection. The bottom edge stays high enough to clear equipment along the wall. Measure the racks and benches before you measure the wall.
Outlets, switches, thermostats, vents. We locate them at measurement so the cutouts get fabricated, not field-cut. That one detail is the single biggest advantage of custom over stock.
Light in front of the mirror flatters. Light behind or beside it defines. Both get decided before the glass is cut.
Sconces at either side of a vanity mirror give the most even light on a face. They beat a single overhead fixture for shaving or makeup, no contest. They also set a hard ceiling on mirror width. So glass size and sconce positions get worked out together, on the same sketch.
Overhead lighting on its own drops shadows down the face. If that is all the room has, a backlit LED mirror is the usual fix.
Going LED? Confirm the power location and the switching before we fabricate. Decide on a dimmer while you are at it. Chasing power behind a finished tile wall is the expensive version of this conversation, and nobody enjoys it.
Custom mirror work follows the same sequence as the rest of our glass projects.
We measure the wall, the vanity, and every obstruction. Then we check whether the wall is flat and the corners are square. Very few are.
We cut the glass to that measurement. Edges get worked to the finish you chose. Backing goes on where specified. Cutouts happen in the shop.
The mounting method depends on the wall and the mirror. Mirror clips, mirror adhesive, channel bars. Each suits a different situation. Heavy or full-wall panels get mechanical support rather than adhesive on its own. Wall prep comes first. A mirror will not hide a bad surface. It magnifies one.
We check the reflection across the whole panel, confirm the mounting is solid, then clean the glass before we pack up.
Timelines move with size, shape, and edge work. Is the mirror landing on a renovation schedule? Tell us at the quote stage. We will plan the sequence around tile, paint, and electrical.
Mirrors are easy to keep. They are also easy to ruin.
Clean with a soft cloth and a non-ammonia glass cleaner. Spray the cloth, never the mirror. Nothing should run down the face and wick into the edges. Moisture sitting along an edge is what causes the black clouding you see creeping in on old bathroom mirrors. Once the backing is gone, the only fix is new glass.
Wipe splashes off the bottom edge of a vanity mirror. Run the bath fan during the shower, and for a while after. Skip abrasive pads. Skip anything with ammonia in it. In a gym, wipe down often. Sweat and chalk dust dull a surface faster than anything a bathroom can throw at it.
We quote mirrors after measurement. There is no honest way to price a custom piece we have not seen. What we can tell you is what moves the number.
Size. Square footage is the base. Large single panels run higher per foot than small ones. Handling and installation get harder as the glass gets bigger.
Thickness. Heavier glass means more material. It also means more labor on the install.
Edge work. Polished is the baseline. Beveled and frosted edges add fabrication time.
Shape and cutouts. Rectangles are the cheapest thing we make. Curves, arches, notches, outlet cutouts. Each one adds shop time.
Safety backing. A modest addition per panel. Non-negotiable in a gym.
Framing and hardware. Frame material and finish can be the biggest single line on a decorative piece.
Access and installation. Stair landings, tall walls, commercial sites. All of them take more crew and more time on site.
It all gets settled during the site visit. Measurement first, quote second. Never the other way around.
Buying to the wall instead of to the vanity. In most bathrooms the cabinet sets the visual width.
Ordering thin glass for a wide span. It will wave. No amount of careful mounting saves it.
Skipping safety backing in a gym. The room where it matters most is the room where it gets cut from the quote first.
Leaving the lighting until last. Sconce and LED decisions change the mirror size.
Field-cutting around outlets. Cutouts belong in the shop, made from measurements taken on site.
Cleaning with ammonia. It goes after the backing at the edges and shortens the life of the mirror.
Measuring the old mirror instead of the wall. The old one may have been the wrong size the entire time.
A custom mirror is a fabrication job. Not a retail purchase. Whoever you hire should measure on site, not take dimensions over the phone. They should talk through thickness and backing in terms of your room. And they should cut and finish glass in their own shop.
Ask who is doing the installation. Ask how the panel gets mounted. Ask what happens if the wall turns out not to be flat. The answers tell you a lot.
Tim's Glass & Mirror is a family-owned glass and mirror shop. We serve homeowners and businesses across Chicagoland, from the North Shore out through the western suburbs. We fabricate and install custom mirrors for vanities, home gyms, dressing rooms, retail interiors, and full walls. We also handle mirror replacement when a piece has cracked or clouded. Our gallery shows completed work. The areas we serve page lists the communities we cover.
Thickness depends on panel size and where the mirror is going. Small framed mirrors can use thinner glass. The frame carries the load and the span is short. Large vanity mirrors, gym walls, and unframed wall installs need heavier glass so the panel stays flat and the reflection stays true. Give your glass company the finished dimensions and the application. Let them spec it.
Yes, safety backing should be standard on any gym mirror. It is a film behind the glass that holds the pieces together if the mirror takes a hit. That matters in a room where weights get dropped and equipment gets swung. The reflection is unaffected. Studios, dance floors, stairwells, and commercial corridors deserve the same treatment.
Yes. Cutouts for outlets, switches, sconces, and thermostats get made during fabrication, from measurements taken on site. It is one of the main reasons to go custom. Field-cutting a finished mirror risks cracking the glass and leaves a rough edge, so we capture those locations at the measurement visit.
A polished edge is ground smooth and flat. You get a clean, almost invisible border that suits modern frameless installs. A beveled edge is cut at an angle around the perimeter, which creates a visible border that catches light and adds depth. Both take off the raw cut edge. The choice is aesthetic. Beveled work runs higher because it takes more shop time.
Custom mirrors get quoted after an on-site measurement. Size, glass thickness, edge finish, shape, safety backing, framing, install access. Every one of those changes the price. No published flat rate covers custom work honestly. Send us your room, your wall dimensions, and the intended use, and you get a number that reflects the actual job.
Choose based on your electrical situation and the look you are after. An LED mirror puts even, shadow-free light around the face. It needs power behind the glass, planned before fabrication. Sconces flanking the mirror deliver similar face lighting, but they cap how wide the mirror can go. Overhead light on its own casts shadows, so most bathrooms want one of the two.
Keep moisture off the edges. That black clouding on old bathroom mirrors is backing damage from water wicking in at the perimeter, and no cleaner takes it off. Spray cleaner onto the cloth, not the glass. Wipe splashes off the bottom edge. Run the bath fan during and after showers. Stay away from ammonia-based cleaners entirely.
In most cases, yes. Say a mirror has cracked, or the backing has clouded, but the frame or surround is still sound. Replacing the glass usually beats rebuilding the whole installation. We measure the existing opening, match or update the thickness and edge finish, then reinstall in the same frame or channel.
