Brother-in-law handled it as part of a bigger project. Chose the fiberglass exterior door. Resists the elements well and looks like real wood. Was upgrading the entry before listing the house — exterior door was priority. One panel rattled slightly until we tightened the pivot hardware. No issues whatsoever.
The glass in the bathroom door had cracked. Full replacement. Chose the exterior door with the raised panel detail. Suits the house style. honestly this thing hits different. My husband and I figured it out together. Works perfectly.
Upgrading the closet doors was the last piece of the bedroom renovation. Neighbor helped — they had all the right tools. Picked the solid-panel closet doors in white. Very clean. Included strike plate was slightly off from our existing prep. real talk — this is a solid door.
Was doing a full studio renovation and doors were on the list. Got the sliding closet door. The bypass track is smooth and quiet. Father-in-law helped out — he's been doing this for decades. Would order from here again without hesitation. Two hinge holes needed slight enlargement.
I’m very happy with these closet doors. The warm wood-tone finish looks beautiful and adds a cozy, modern touch to the room, while the frosted glass panels let light pass through but still keep things private. It instantly made the closet area look more stylish and refined.
Bypass doors are sliding closet doors made of two or more panels that move side to side on parallel tracks, passing in front of or behind one another. Because they don’t swing outward, they don’t require extra floor space for door clearance.
What Are Bypass Doors?
Bypass doors are a type of sliding closet door where each panel is hung on its own independent track, allowing one panel to slide directly behind the other for full opening access without any swing radius.
This “double-track” design is what separates true bypass hardware from a single pocket door or a bifold system. Because the panels overlap rather than fold or disappear into a wall cavity, bypass closet doors work in almost any room, including homes where wall framing can’t accommodate a pocket door pocket.
They’re especially valuable in bedrooms, hallway linen closets, and reach-in wardrobes where a swinging door would collide with a bed, dresser, or foot traffic. If you’re searching for sliding wardrobe doors that combine easy DIY installation with a clean, built-in look, bypass hardware remains one of the most practical and budget-friendly choices on the market.

How to Choose Bypass Doors for Your Space
Choosing the right bypass door starts with measuring your opening, then matching panel configuration, style, and budget to the room. See our Door Measurement Guide for step-by-step instructions.
Application and room type. Decide whether the doors are for a bedroom closet, pantry, or hallway linen closet, since each favors different panel widths.
Panel configuration. Compare simple double sliding doors against triple bypass setups for wider openings.
Opening dimensions and panel overlap. Measure the rough opening width and height precisely; panels typically need 2–3 inches of overlap for full coverage without light gaps.
Budget alignment. United Porte’s bypass door models start from $492492, with pricing scaling by material, size, and glass or mirror upgrades.
Installation of Bypass Interior Doors
Bypass closet doors can be installed as a DIY kit using the included top track and floor guide, or through white-glove professional installation for a guaranteed fit.
Proper installation hinges on three things: level top-track alignment, correctly positioned floor guides, and accurate panel overlap so the doors close flush without gaps or friction. DIY installation is realistic for handy homeowners with basic tools, but uneven openings, out-of-square framing, or heavier mirror and glass panels often benefit from professional measuring. United Porte offers turnkey measurement and installation service in supported markets, so panels are fitted, leveled, and track-tested by trained installers rather than guessed at. Check our bypass door installation guide.
Care and Maintenance of Interior Sliding Bypass Doors
Keeping bypass doors gliding silently mainly comes down to regular track cleaning and roller adjustment.
Lubricate tracks and rollers every few months with a dry silicone-based lubricant, not oil, which attracts dust.
Clean glass or mirrored surfaces with a standard glass cleaner and lint-free cloth to prevent streaking.
Check alignment screws on hangers periodically, tightening any that loosen from repeated use.
Wipe down frame finishes to remove dust buildup that can interfere with smooth panel bypassing.

Frequently Asked Questions
What are bypass doors?
Bypass doors are sliding closet doors made of two or more panels that move on parallel tracks, with one panel passing behind the other to open. They’re a popular alternative to hinged doors in rooms where swing clearance isn’t practical.
Are bypass doors the same as sliding closet doors?
Yes — “sliding closet doors” is the common name for bypass doors, referring to the same double-track sliding mechanism. The terms are used interchangeably by most homeowners and retailers.
How do bypass doors work?
Bypass doors work by hanging each panel from its own rail so the panels overlap and slide horizontally past one another. This lets one section of the closet open at a time while the other panel bypasses behind it.
How do you install bypass doors?
Installing bypass doors involves mounting a top track level across the opening, hanging the panels on their rollers, and securing a floor guide to keep the bottom edges aligned. Panel overlap and door height are then adjusted for a smooth, gap-free close.
How much should bypass doors overlap?
Bypass door panels typically need a 2–3 inch overlap where the two doors meet in the closed position. This overlap prevents light gaps and keeps the closet fully covered.
What sizes do bypass doors come in?
United Porte bypass doors come in several sizes, with 36″ × 80″ being the most common in the current catalog. Other listed sizes include widths up to 72″ and heights of 80″, 84″, and 96″. Some models also offer additional custom-size options for different openings.
How much do bypass doors cost?
Bypass door pricing at United Porte starts at $492492 for entry-level configurations, with the final price depending on material, size, and glass or mirror upgrades. The full catalog of 528 models spans multiple price tiers to fit different budgets.
