Absolutely stunning door. The craftsmanship is incredible — you can feel the weight and quality the moment it arrives. Installed it in our master bedroom and it completely transformed the space.

Worth every penny. We were nervous ordering a custom door online but the team walked us through measuring and the door fit perfectly. Hardware included was a huge bonus.

James K.Nashville, TN✓ Verified

★★★★☆

Beautiful door, great quality wood. Delivery took about 3 weeks which was within the estimate. Only wish they had more stain color samples available to ship.

A Mirror That Earns Its Wall

Closet doors usually take a wall and give nothing back. This one hands you a full length mirror at the exact place you need one, which is directly in front of the clothes. Two panels, each glazed floor to head height, hung on a bypass track so one always covers the opening while the other stands open.

The mirror is set into a clean painted frame with a narrow reveal, so what you see is glass and a thin line of trim, not a heavy border. From a few feet back the doors read as light rather than as objects, which is precisely why they work in a hallway that would otherwise feel tight.

It is the most practical door in the catalog, and the one people notice least until they live with it.

Design Details

Full Length Mirrored Panels

Glazed nearly the full height of each slab, so you get a dressing mirror without giving up a second wall to one.

Narrow Painted Reveal

The frame is kept deliberately slim. The eye lands on the reflection, not on the woodwork around it.

Hung as a Bypass Pair

Two panels on one track. Half the opening is always accessible and neither door needs swing clearance into the room.

Brightens Tight Spaces

In a narrow hall or a windowless dressing area the mirrored face doubles the light the room already has.

Mirror Glass Needs a Frame That Does Not Move

Mirror is unforgiving. A frame that racks even slightly will stress the glass and distort the reflection, so the panel behind it has to be dead square and it has to stay that way. We build these in Bucks County, Pennsylvania from solid wood, square them on the bench, and back the frame with our lifetime warranty. A warped door is a broken mirror, eventually, and we do not intend to find out.

How to Measure Your Opening

A few quick measurements and we build your door to fit perfectly.

Measure the Width

Measure across the opening with the trim included. If there is no trim, measure just the width of the opening itself.

Measure the Height

Measure the total height of the opening including the trim. If there is no trim, measure just the height of the opening.

Leave Room for Hardware

Allow at least 6″ of clearance above the opening (or above the trim) for the track hardware. Bypass doors need a minimum of 9″.

We Handle the Coverage

No trim? We add 4″ to the width (2″ each side) and 1″ to the height for proper coverage. With trim, we build the door to extend slightly past it.
