Choose clear glass if your tile is medium or dark and you want the standard option. Choose low-iron glass if your tile is white or very light and you want the glass to show its true color. For Massachusetts homeowners ordering a frameless door, both are 3/8 inch tempered safety glass; the only real difference is color, because clear glass has a slight green tint, most visible on the edge, and low-iron has almost none.
Why does regular clear glass look a little green?
Standard glass contains a small amount of iron, and iron gives glass a green cast. Looking straight through a panel, you barely notice it. Looking at the edge, or through the glass at an angle, you do.
Two things make the tint easier to see in a shower:
- Thickness. A frameless door uses 3/8 inch glass, which is heavier than the glass in a store kit. The thicker the panel, the more green shows at the edge.
- Size. A floor to ceiling panel or a corner enclosure gives you more glass to look through, and in a corner you look through two panels at once where they meet.
Low-iron glass is made with much less iron, so the edge looks close to white and the tile behind it keeps its own color.
Clear vs low-iron at a glance
| | Clear glass | Low-iron glass | |---|---|---| | Color through the glass | Very light green tint | Almost no tint | | Edge of the panel | Visibly green | Close to white | | Thickness for frameless | 3/8 inch tempered | 3/8 inch tempered | | Works best with | Gray, beige, dark or colored tile | White, cream or light veined tile | | Cost | Standard | Upgrade, costs more | | Cleaning and care | Same | Same |
When is clear glass the right choice?
Clear glass is our standard for a reason. It looks great in most bathrooms, and in many of them nobody will ever notice the tint.
Clear is usually the better pick when:
- Your tile has color or depth. On green, blue, gray, beige or dark stone tile, the slight green of the glass blends into the wall. The door in the photo above sits against green tile, the kind of setting where the tint is hard to spot.
- The opening is a standard size. A single door on a three wall shower has less glass and fewer edges in view.
- You want to put the budget elsewhere. Some homeowners would rather spend the difference on a hardware finish they love or on the tile itself.
When is low-iron glass worth the upgrade?
Low-iron earns its cost when the glass is a big part of what you see in the room. Consider it when:
- Your tile is white or very light. Bright white tile and light veined tile are where green edges stand out the most. Low-iron keeps the white looking white.
- The glass is large. Floor to ceiling panels, wide openings and corner enclosures put a lot of glass in view.
- The shower is the centerpiece of the bathroom. In a primary bath remodel where the shower is the first thing you see from the door, many people decide the upgrade is worth it.
A simple test: if you will look at the edge of the glass every morning and it would bother you to see green, go low-iron. If you would never think about it, clear is enough. You can see both options, and every hardware finish, on our frameless shower doors page.
Does low-iron change strength, safety or cleaning?
No. Both types are tempered, both are the same 3/8 inch thickness for our frameless builds, and both use the same CRL hinges, clamps and handles. The installation is the same and takes about two hours either way.
Care is the same too. Water spots and soap residue show on any glass, so a quick squeegee after a shower helps more than the glass type. Low-iron does not make a door harder or easier to clean.
How do you decide without seeing both side by side?
Start with your tile. Look at a sample or a spare piece in daylight. If it is bright white or very light, lean low-iron. If it has color, lean clear.
Then send us one photo of your shower. Midia replies with your price and can quote both glass types so you can compare. At the free in-home measurement we confirm the final design with you, glass and hardware included, before anything is made. If price is the deciding factor, our frameless shower door cost guide explains how the glass type affects the total along with the other factors.
Replacing an old door? If your current one is cloudy or framed in metal you no longer like, a full shower door replacement is the right moment to make this choice. The old door comes out and a new custom door, clear or low-iron, is made for your opening.
Frequently asked questions
Is low-iron glass the same as extra clear or ultra clear glass?
Yes. Glass makers use names like low-iron, extra clear and ultra clear for glass made with less iron. They all describe the same idea: glass with almost no green tint.
Will I see the green tint from inside the shower?
Mostly at the edges and when you look through the glass at an angle. Looking straight through a clear panel, the tint is very light.
Is low-iron glass stronger than clear glass?
No. In our frameless doors both are 3/8 inch tempered safety glass. The difference is color, not strength.
Can I use low-iron for the door and clear for a fixed panel?
Most homeowners keep the same glass on every panel, because side by side the two look slightly different. If you are considering it, ask Midia at the free measurement.
Which glass should I pick for white subway tile?
Low-iron is usually the better match for bright white tile, because it keeps the grout lines and the tile from looking tinted.
