Hide Under Stairs Storage (Curtain Ideas)
A curtain can hide bins, shoes, or seasonal items beneath a staircase while keeping the space easy to reach. First, measure the opening and check for stairs, doors, vents, alarms, and electrical equipment. Choose a track that suits the opening and is fixed to framing or rated backing. A curtain does not replace required fire protection or electrical clearances.
The awkward shape under a staircase can make ordinary shelves and cabinets hard to use. A curtain is often a simpler way to conceal storage, but the area may also contain equipment or have code requirements. I plan these projects by checking access and safety first, then choosing a curtain that fits the opening and the items stored there.
Plan the Opening and Identify Code Triggers
Start by measuring the space and noting anything that could affect the curtain or storage. An opening’s width and height are only part of the picture: floor changes, the stair slope, and nearby doors or equipment can limit where a track can go. Check local rules before covering an enclosed under-stair space.
Measure the opening at the top and bottom, since walls and floors may not be square. Record the usable height at several points along the stair slope. Also note nearby handrails, doors, outlets, alarms, HVAC grilles, and electrical panels. These checks help you avoid a curtain that catches, blocks access, or covers something that needs attention.
The IRC, or International Residential Code, includes fire-protection rules for enclosed, accessible spaces beneath stairs. Section R302.7 calls for ½-inch gypsum board on the enclosed side of the under-stair surface. Confirm which code edition and local amendments apply where you live. A curtain alone does not establish whether a space is legally “enclosed,” and it does not replace required gypsum board.
Before buying materials, ask your local building department or a qualified professional if you are unsure whether the rule applies to your setup. Do not remove existing protective finishes to make room for a track or curtain. Keep any required finish intact and unobstructed.
Preserve Stair and Equipment Access
The curtain should conceal stored belongings, not reduce safe stair use or block equipment that needs working space. Check its position when open and closed, and make sure fabric, track, and stored items stay clear of steps, handrails, doors, vents, and alarms.
An electrical panel behind a curtain still needs its required working space. Under NEC 110.26(A), a common working-space requirement is 30 inches wide, or the equipment’s width if greater, 36 inches deep for equipment 0–150 volts to ground, and 6 feet 6 inches high. Conditions and exceptions apply, so confirm the rules for the equipment and location. Do not put a curtain or stored items in required working space.
A curtain may be able to sit outside that clear area, but it must not prevent access to the equipment. If the curtain crosses the working space or the equipment cannot be reached as required, choose another storage location or ask a qualified electrician for advice. Never treat a curtain as permission to store boxes in front of a panel.
Also keep fabric away from HVAC grilles and alarms. Blocking airflow or access can affect how equipment works. If a door swings into the opening, test the full swing before mounting anything.
Choose a Curtain Style and Track
A suitable curtain covers the opening but moves aside easily. Fullness means the extra fabric gathered along the track; a design target is finished curtain width of about 1.5 to 2 times the opening width. This allows folds when closed and enough fabric to cover the opening without pulling taut.
| Option | Works well for | Check before choosing |
|---|---|---|
| Ceiling or underside track | A low opening or a track mounted to suitable framing | Confirm the track will not touch stair parts or reduce clearance |
| Wall-mounted track | A flat wall face around the opening | Check whether the wall can support the track and curtain |
| Tension rod | A light curtain between sound, parallel surfaces | Do not assume it can hold heavy fabric or repeated pulling |
| Split curtains | A wide opening where access from the middle is useful | Leave enough space for both panels to gather at the sides |
Treat the table as a starting point, not a load rating. Check the track or rod maker’s published limits for the exact product and mounting method. There is no universal code load rating for an under-stair curtain. Do not mount a loaded track to drywall alone. Fasten it to framing or securely installed, rated backing.
Choose fabric based on use. A washable, light fabric may suit shoes or everyday items. Heavier fabric can be harder to move and puts more load on the support. For storage used often, make sure the curtain can open wide enough to reach the back without dragging across belongings.
Install the Track and Curtain
A secure installation begins with locating support, not drilling at guessed points. A track’s published rating only helps when the fasteners and mounting surface also suit the load. Follow the product instructions, use appropriate fasteners, and ask a qualified installer if you cannot confirm framing or backing.
- Survey the opening. Measure width, height, and floor variation. Check the stair geometry and nearby doors, handrails, outlets, panels, alarms, vents, and equipment.
- Resolve clearances. Confirm that the curtain will not intrude into the stair path or required equipment working space. Check whether the accessible under-stair area is enclosed and whether local fire-protection rules apply.
- Locate support. Find framing where the track will be mounted. If it is not in a useful position, install securely fastened backing suited to the track and the structure. Do not rely on drywall alone.
- Mount and test the track. Follow the maker’s spacing and fastener directions. Move the track or curtain through its full travel before adding fabric. It should not strike the stair, trim, or other fixtures.
- Fit the curtain. As a design target, use finished width around 1.5 to 2 times the opening width. Set the hem about 1 inch above the floor to reduce dragging and snags; adjust for uneven flooring and the stair slope.
- Check the finished setup. Open and close the curtain fully. Confirm that equipment, vents, alarms, stairs, and any required fire-protection finish remain clear and accessible.
Verify Clearances and Fire Protection
A finished curtain should move freely, cover the intended storage, and leave safety features usable. Verification means checking the installation in both positions, not just when the fabric is pulled closed. If anything is blocked or catches, adjust the layout before loading the storage area.
Check the full stair route with the curtain open and closed. Fabric must not narrow the stair or catch on a handrail. Check equipment access and any applicable electrical working space, and keep vents and alarms clear. If the under-stair area is enclosed and accessible, verify the local requirements for its protected surfaces; a curtain is not a substitute for required gypsum board.
Worked examples
These are illustrative layouts, not reports of measured client projects. They show how the same checks apply to different openings.
- Shallow shoe storage: For a sample opening 36 inches wide, a finished curtain width of about 54 to 72 inches follows the 1.5-to-2-times design target. Measure the opening at more than one point, and keep the hem about 1 inch above the floor, adjusting for unevenness. A light curtain can hide shoes while leaving the space easy to reach.
- Panel near the opening: If an electrical panel is under the stairs, first identify its required working space. Do not put fabric, bins, or stored items in that area. If the curtain would block access or enter the required space, do not install it there; get advice from a qualified electrician.
A useful final test is to pull the curtain all the way open, reach every stored item, and check all equipment without moving the track or taking down the fabric. If that test fails, revise the storage plan.
Frequently Asked Questions
These answers cover common choices for hiding under-stair belongings with a curtain. Exact code duties depend on the adopted rules and the site. When a question involves electrical equipment or required fire protection, confirm the details locally rather than relying on the curtain design alone.
How wide should an under-stair curtain be?
As a design target, make the finished curtain about 1.5 to 2 times the opening width. The extra fabric lets it gather and still cover the opening.
How far above the floor should the hem sit?
About 1 inch is a useful design target to reduce dragging and snagging. Adjust it for an uneven floor or the stair slope.
Can I use a tension rod?
Only if the rod maker’s rating and instructions suit the curtain and the surfaces holding it. Do not use an unrated rod or assume it can support heavy fabric.
Can I attach the track to drywall?
Do not fasten a loaded track to drywall alone. Fasten it to framing or securely installed, suitable backing, and follow the track maker’s instructions.
Can a curtain cover an electrical panel?
A curtain does not remove the panel’s access or working-space requirements. Keep the required area clear of fabric and stored items, and confirm the applicable rules.
Does a curtain meet under-stair fire-protection rules?
No. Where IRC R302.7 applies, it calls for ½-inch gypsum board on the enclosed side of the under-stair surface. Check the locally adopted code and whether the space qualifies as enclosed and accessible.
Can the curtain touch the stairs?
It should not catch on or interfere with the stair, handrail, or walking path. Test the curtain through its full travel before use.
What should I check before installing a track?
Measure the opening and floor, locate framing or suitable backing, and check nearby doors, vents, alarms, outlets, panels, and equipment. Confirm local code needs before covering the area.
Make the Storage Easy to Use
A well-planned curtain hides everyday clutter without making the space harder to reach. Measure first, check the stair path and nearby equipment, choose a rated support, and keep any required fire protection intact. Before storing anything, open and close the curtain and confirm that every needed clearance and access point remains clear.
