Frameless / Grid Mullions

Grid Shower Enclosures

A grid shower enclosure is a flat-panel frameless shower built with applied or integrated black-metal grid mullions across heavy tempered glass, drawing the Crittall-window, industrial, and loft aesthetic into the bathroom as a single architectural statement. Homeowners, designers, and architects choose the grid look when the bath is meant to read like a designed room rather than a builder-grade upgrade: the divided-light pattern adds geometric contrast against subway, large-format, and zellige tile, and the matte-black mullions anchor an industrial-modern or modern-farmhouse palette. Moffat Glass fabricates and tempers every panel in-house at our Northern Colorado shop, so the grid configuration, glass thickness, and hardware finish are spec'd to one bathroom rather than pulled from a stock catalog.

How It Works

Grid shower enclosures are built one of two ways, and the right choice comes down to the look you want and how the framework needs to sit in the opening.

An applied-grid build attaches a black-metal grid to the face of a single tempered glass panel; it reads as Crittall-style from across the room and leaves a smoother interior surface for cleaning. An integrated divided-light build uses true structural mullions with individual glass panels set into the framework; it reads as a true factory window with more visual depth and shadow at the joints.

Design & Configuration

Grid enclosures come as applied-grid or integrated divided-light builds. Configurations include fixed panels, hinged swing with inline side panels, sliding, and corner builds, with grid layouts running from perimeter-only to internal horizontal and vertical lines.
Opening

Alcove, Single-Wall, or 90° Corner

Grid layouts work cleanly in alcove openings, single-wall flat-panel runs, and 90-degree corner footprints. Configurations include fixed panels, hinged swing with inline side panels, sliding, and corner builds.

Glass

3/8" or 1/2" Tempered Heavy Glass

Most residential grid enclosures use 3/8" tempered heavy glass, stepped up to 1/2" tempered for larger panels or wider spans. Glass is cut, tempered, and fitted to one opening.

Hardware

Matte-Black Grid & CRL Hardware

Hardware comes from CRL (C.R. Laurence), specified in matte black to match the grid finish, with oil-rubbed bronze and brushed gold available where the palette calls for it.

Construction

Applied-Grid or Integrated Divided-Light

Applied-grid attaches a black-metal grid to the face of a single tempered glass panel for a smoother interior surface. Integrated divided-light uses true structural mullions with individual glass panels for more visual depth.

Placement & Installation

Grid enclosures show up most often in industrial-modern, loft, modern-farmhouse, and Crittall-inspired primary baths, and they work cleanly in alcove openings, single-wall flat-panel runs, and 90-degree corner footprints.

Because the grid geometry is angular and flat-panel rather than curved, the install relies on accurate templating: we measure the opening on-site, confirm the grid configuration (panel count, line direction, joint placement) with the homeowner or designer, then fabricate and temper the panels at our Northern Colorado shop. Integrated divided-light builds require extra attention to the framework's structural support at the curb and ceiling.

Custom grid shower enclosures install in 1–2 weeks from approved measurement, vs. 2–3 weeks for vendors who outsource shower-door fabrication out of state, and applied-grid versions often run on the shorter end of that window.

Care & Maintenance

01

Squeegee the glass after every use to keep water spotting and soap film off the panels.

02

Clean with a non-abrasive glass cleaner and skip anything ammonia-based — ammonia degrades the powder-coat on the grid finish.

03

On integrated divided-light builds, give gentle attention to the mullion joints during routine cleaning to keep moisture from settling at the grid intersections.

04

Use a soft microfiber cloth on the matte-black grid and hardware — these finishes are sensitive to abrasive pads.

Common Questions About This Style

What makes a grid shower enclosure different from a standard frameless shower?+

A grid shower enclosure pairs heavy tempered glass with a black-metal grid pattern across the panels, drawing the Crittall-window aesthetic into the bathroom; a standard frameless shower is a flush glass enclosure with no mullion pattern. Moffat fabricates both applied-grid and integrated divided-light versions in-house in Northern Colorado.

What's the difference between applied-grid and integrated divided-light construction?+

An applied grid is a black-metal grid attached to the face of a single tempered glass panel; an integrated divided-light enclosure uses true structural mullions with individual glass panels set into the framework. Applied-grid versions read as Crittall-style from across the room and leave a smoother interior glass surface for cleaning. Integrated divided-light reads as a true factory window with more visual depth and shadow at the mullions. Glass is 3/8" or 1/2" tempered heavy glass in either build.

How much does a custom grid shower enclosure cost in Northern Colorado?+

Custom grid shower enclosures price above flat-panel frameless doors because the matte-black grid adds fabrication and finish work on top of the heavy-glass base. Cost varies by construction type, glass thickness, panel count, hardware finish, and grid layout, so every quote is project-specific.

How long does it take to install a grid shower enclosure?+

Moffat installs most custom grid shower enclosures in 1–2 weeks from approved measurement. Vendors who outsource fabrication out of state typically run 2–3 weeks; our Northern Colorado shop tempers and finishes every panel locally. Applied-grid versions often run on the shorter end of that window, and integrated divided-light builds run on the longer end.

I do not hesitate to recommend Moffat Glass

"We needed our patio screen door replaced. Moffat answered the phone (something that 3 other businesses did not do), scheduled someone to come measure the same day, manufactured our non-standard sized door and installed it within a week. We have yet to hear from the other businesses we contacted who told us they would 'get right back' to us. The quality of customer service was very good. Everyone was friendly, professional, and expressed appreciation for our business. I do not hesitate to recommend Moffat Glass. They have been in Greeley for a long time and I can see why they have lasted."
