For most homeowners renovating a corner shower, a custom frameless 90° hinged door with a fixed return panel is the best choice. It delivers a clean, open look, works with most bathroom layouts, and installs more cleanly than a sliding system. Glassshowerdirect’s online builder lets you configure one to your exact dimensions and order directly from the factory, cutting out the middleman markup. Before you go any further, lock in these three decisions:
Glass thickness: 3/8″ (10mm) tempered safety glass is the standard and most commonly specified for frameless corner enclosures. It meets safety requirements and provides the rigidity frameless hinges need.
Hinge hardware: Patch hinges or pivot hinges for a true frameless look. Skip the frame.
Easy-clean coating: A hydrophobic surface coating dramatically reduces daily scrubbing. Choose it at the time of order, not as an afterthought.
Pro Tip:Hinged doors are the right call for most 90° corners. Sliding systems often require a top header rail that conflicts with the compact geometry of a right-angle corner, adding bulk and complexity. Go with a slider only if a physical obstruction makes a door swing impossible.
What are the main 90 degree shower enclosure layouts?
Three configurations dominate the corner shower market, and each suits a different bathroom situation. Single door + 90° return panel is the most common layout. Two existing walls form the corner, one fixed glass panel runs along one wall, and a hinged door swings from the other. It’s simple, clean, and works beautifully in both small and generous bathrooms. The square corner enclosure uses slightly more floor space than a neo-angle but feels open and airy when the glass is frameless. Neo-angle cuts the corner at 45°, replacing the sharp 90° junction with an angled front panel. The door hinges from that short center panel. This layout fits the same footprint as a square corner but softens the visual weight, making it a popular pick for bathrooms where the shower is the focal point. Neo-angle enclosures often come with integrated low-profile seals and self-closing hinges. Sliding or round-slider works when a door swing is genuinely impossible, such as when a toilet or vanity sits directly in the swing path. The trade-off is a header rail and track, which add visual weight and require more maintenance. For a right-angle corner, professionals frequently recommend hinged doors over sliders for exactly this reason.

Pro Tip:Choose a neo-angle over a square 90° corner when your bathroom space is limited. The angled front panel reduces the visual “block” effect and can make a small bathroom feel less like showering in a closet.
What glass, hardware, and finish options do you need to choose?
This is where your enclosure goes from generic to yours. Every choice here affects price, weight, and how the finished product looks in your bathroom.
Glass thickness and type
Three thicknesses are used for frameless corner enclosures, but 3/8″ (10mm) tempered safety glass is the most common and recommended standard. It balances rigidity, weight, and hardware compatibility for most projects. 1/4″ (6mm) is sometimes used for small or secondary panels, and 1/2″ (12mm) is reserved for especially large spans that require maximum rigidity and heavy hardware. Clear glass is typically chosen to maximize light and reveal tile work. Low-iron glass is ultra-clear with no green tint, ideal for white or light-colored tile. Frosted or textured glass adds privacy. You can explore the clear vs. frosted glass comparison to help decide.
Hardware and finish
Hardware finish sets the tone for the whole bathroom. Common options include chrome, brushed nickel, matte black, and warm brass tones. Matte black reads as modern and bold; brushed nickel is the safe, timeless pick that coordinates with almost anything. Hinge style matters too. Patch hinges mount directly to the glass with no frame, giving the purest frameless look. Pivot hinges work at the top and bottom of the door for heavier 1/2″ panels. Handle style, from simple towel bars to D-pulls, is mostly personal preference, but longer handles are easier to grip with wet hands.

Thicker glass always means heavier hinges, more robust wall anchoring, and a higher price. Budget accordingly when you step up from 3/8″ to 1/2″.
How do you measure for a 90° corner frameless enclosure?
Accurate measurements are the single biggest factor in whether your enclosure arrives ready to install or needs a costly recut. Take your time here.
Measure both wall widths at three heights: near the floor, at mid-height, and near the top. Use the smallest measurement on each wall. Walls are rarely perfectly plumb.
Measure the height from the finished floor (or top of the shower pan) to where you want the glass to end. Account for any ceiling slope.
Check for plumb and level. Use a level on both walls. Note any out-of-square conditions in writing. Glassshowerdirect’s online builder has fields for noting these variations.
Confirm door swing clearance. A hinged door needs at least the door width plus a few inches of clear floor space in the swing arc. Measure from the hinge point outward.
Account for tile and substrate thickness. If tile is not yet installed, add the tile thickness to your wall measurements.
Confirm handing. Stand inside the shower facing the door opening. If the hinges are on your right, it’s a right-hand door. Note this before you order.

What does a custom 90° enclosure cost, and how long does it take?
Custom frameless enclosures are priced by configuration, glass thickness, and hardware finish. A straightforward single-door-plus-return in 3/8″ clear glass with standard hardware typically runs in the mid-hundreds to low thousands of dollars, depending on panel size. Stepping up to 1/2″ glass, low-iron clarity, or a premium finish like matte black or brushed brass adds to the total. Easy-clean coatings are usually a modest add-on at checkout. Lead times for factory-direct custom glass orders typically run two to four weeks from order confirmation to shipping, though this varies with order volume and complexity. Factory-direct online builders reduce turnaround by eliminating the distributor step, which can add days or weeks to a traditional showroom order. Plan for these potential additional costs:
Crating and freight: Heavy glass ships on pallets. Confirm whether your quote includes curbside or threshold delivery.
Installation labor: A professional installer typically charges by the hour or by the job. Get a quote before you order so you can budget the full project.
Returns or recuts: Incorrect measurements are the most common reason for reorders. Double-check everything before you submit.
Hardware upgrades: Premium finishes and heavy-duty hinges for 1/2″ glass cost more than standard chrome.
Should you hire a pro or install it yourself?
Hire a professional installer when your walls are out of square by more than 1/4″, when you’re working with 1/2″ glass panels (which are genuinely heavy), or when the enclosure involves knee walls, curbs, or complex tile work. A frameless enclosure that’s slightly off-level will leak, and fixing it after the fact is expensive. DIY is feasible for a straightforward single-door-plus-return in 3/8″ glass if you’re comfortable with a drill, a level, and basic silicone work. You’ll need a helper for the glass panels regardless. Glassshowerdirect’s how-to installation video walks through the process step by step. A professional installer will need:
Verified, finalized measurements (not estimates)
Fully tiled or finished walls and floor before glass arrives
Clear access to the shower area with room to maneuver panels
A helper for lifting and positioning glass
Silicone caulk, a level, and the hardware pack that ships with the enclosure
A typical installation runs several hours for a standard 90° corner enclosure. Silicone cure time is needed before the shower is used. Pro Tip:Lay moving blankets or cardboard on finished tile before installation begins. Glass panels set down on bare tile can scratch or chip the surface, and that’s a repair nobody wants.
How do you keep frameless glass looking new?
An easy-clean coating does most of the work, but a simple daily habit keeps mineral buildup from ever becoming a problem. Squeegee the glass after every shower. That one step removes most of the water that would otherwise leave calcium deposits. Weekly and monthly care:
Spray with a pH-neutral cleaner (avoid anything acidic or abrasive) and wipe with a microfiber cloth.
Skip steel wool, scouring pads, or powdered cleansers. They scratch the glass surface and degrade the coating.
Rinse the door tracks and seals monthly to prevent soap scum buildup in the corners.
Hydrophobic easy-clean coatings bond to the glass surface and cause water to bead and roll off. Most coatings perform well for several years with proper care, though some manufacturers recommend a reapplication treatment after heavy use. For daily maintenance tips specific to frameless glass, Glassshowerdirect has a dedicated guide. Pro Tip:Hard-water stains that won’t budge with a standard cleaner respond well to a paste of baking soda and white vinegar, applied gently with a soft cloth. For severe mineral buildup, a professional glass restoration service can polish the surface without damaging the coating.

A perspective on getting the order right the first time
The most common frustration with custom glass orders isn’t the product. It’s the measurement. Homeowners spend weeks choosing a finish and a layout, then rush the measurement step because it feels like the easy part. It isn’t. What actually matters is the sequence: measure first, choose glass second, confirm handing third, then order. Most reorders and recuts trace back to a measurement taken before tile was installed, or a handing note that got flipped between the bathroom and the order form. The online builder helps, but it can only work with the numbers you give it. The other thing worth saying plainly: a frameless 90° corner enclosure is a real upgrade. It opens up a bathroom visually in a way that a framed unit simply doesn’t. The glass reads as part of the room rather than a barrier inside it. That effect is worth the extra care in the ordering process.
