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.

★★★★☆

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.

Three Lites, Stacked in a Shaker Frame

The 3 Lite Shaker is a study in restraint. A plain shaker frame, three glazed openings stacked vertically, and a clean rail between each one. There is no muntin work, no grid, no arch, nothing except the rhythm of three squares in a column.

Because the rails between the lites are narrow and even, the door reads as one tall glazed field that has been divided rather than three windows that were assembled. That distinction is what keeps it modern.

Hung as a bypass pair in white, as shown, the six lites line up across the opening and the whole wall becomes a lantern for the room behind it.

Design Details

Three Even Lites

Equal openings stacked in a column. The proportion is what carries the door, so the rails between them are cut to the same width as the stiles.

No Muntins

Nothing crosses the glass. Each lite is a single unbroken opening, which keeps the door reading as light rather than as pattern.

Shaker Frame

A flat stile and rail frame with square edges. It stays out of the way of the glass, which is its entire job here.

Aligns Across a Pair

Two panels on a bypass track put six lites in a single row of columns, with the rails lining up across the seam.

Choosing Your Glass

This door is glazed. Acid etched is the frosted white shown here and the natural choice for a bathroom or a closet where you want light without a view. Rain adds a vertical ripple that plays against the horizontal rails. Reamy brings a soft handmade waviness that warms up the cleanness of the shaker frame. Aquatex is a finer pebbled texture, quieter than rain and more private than clear. Select yours above before adding the door to your cart.

Three Openings, Three Chances to Rack

Every lite you cut into a door removes material that was holding it square. A three lite frame has to be joined well or it will rack on the track within a season. Ours are built from solid wood in Bucks County, Pennsylvania, squared on the bench, and warrantied for life against warping and twisting.

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.
