Under Stairs Storage Ideas to Build Into Your Remodel

The average home has about 30 to 60 square feet of usable space hiding under the stairs. Think about it: that's a lot of wasted room not being put to good use. A remodel can turn this space into under stairs storage configured for a surprising range of functions. While adding shelving is the most obvious idea, other possibilities include a designated pet lounge, mini-office, laundry space,  or even a bathroom.

From clever cabinetry to cozy reading nooks, here are diverse under stairs storage ideas to inspire your next remodel.

Slide-out pantry for kitchen staples

If your stairs are near the kitchen, transform the unused space into a slide-out pantry for snacks, canned goods, and spices. Full-extension shelves maximize storage, and adjustable heights allow you to fit everything from tall bottles to bulky appliances.

If your kitchen is short on cabinet space, this is probably the single most useful thing you can do with the under-stair area; when the doors are closed, nobody even knows it's there.

Install a wine cellar or beverage bar

Dedicated wine storage beneath the stairs frees up cabinet space and gives you a place to show off your collection. Incorporate wine cubbies, glass storage, and even a fridge, all illuminated with subtle accent lighting. Parents with teenagers can even add lockable glass doors to lessen any temptation. 

Create a cozy reading nook

A reading nook works best in wider stairwells where you can fit a bench at least 24 inches deep. Add a cushion, a wall sconce or recessed LED, and some shelving for books, and you've got a spot that actually gets used. Bonus idea: the bench lid can open for blanket or board game storage underneath.

Design a built-in pet retreat

Dogs especially love a den-like space, and the under-stairs nook is a natural fit. Set up a raised platform or cushioned bed, a feeding station, and a couple of bins for leashes and toys. Use tile or sealed laminate on the floor; trust us, you'll want something you can wipe down.

Maximize with entryway mudroom lockers

Transform your under-stairs space into a mini mudroom with cubbies, hooks, and storage benches for coats, backpacks, and shoes. Closed cabinets or labeled baskets can help bring order and discretely hide messes. Go with scratch-resistant melamine or painted MDF for the cabinet faces. 

Build a compact home office or study desk

You don't need much room to carve out a workspace under the stairs. Even a 36-inch-wide alcove is enough for a functional desk, a shelf or two, and a task light. Match the surface material to your existing stair trim and it'll look "built-in" rather than "bolted on." For more guidance, read Home Office Renovation Ideas That Actually Improve How You Work.

Organize with a pull-out pantry for cleaning supplies

This is one of the simplest under stairs storage ideas to pull off. Tall, narrow pullouts (look for 6- to 9-inch-wide models) can hold mops and spray bottles upright. Add a few hooks on the inside of the door for dustpans and rags, and you've got a cleaning closet that does its job. 

Make toy storage with slide-out bins

Slide-out bins under the stairs are a sanity saver if you have young kids. Open cubbies with a bin per category (i.e., Legos, Barbies, art stuff) make cleanup something a four-year-old can handle on their own. 

Install built-in bookshelves

Use the full stair wall for under stairs shelving ideas that double as a display. Closed cabinets at the bottom hide clutter; open shelves above show off books, plants, or framed art. Puck lights or an LED strip along the top row make the whole thing look intentional, especially at night. This one's worth going custom on, since off-the-shelf bookcases will never follow the stair angle cleanly.

Add a mini laundry station

Tuck a stacked washer and dryer, folding surface, and storage drawers into the stair cavity for a streamlined laundry room solution. Make sure you plan for airflow. The dryer vent run is the main constraint here, so check the distance to an exterior wall before committing. Waterproof wall panels or tile on the floor will hold up to moisture. A tension rod for air-drying and a fold-down countertop for sorting are easy adds that make the space feel like a real laundry room.

Outfit with an under-stairs closet

If you don't want to overthink it, just build a closet. A rod for hanging, a shelf above it, and a drawer or two below covers the basics. A mirrored door on the front makes the hallway feel bigger and gives you a last-look spot on the way out. This is the easiest understairs storage ideas option to execute, and is especially practical if you're building a bedroom in your basement . Most contractors can knock it out in a day or two.

Design a kids’ art station

Inspire creativity with a pint-sized workspace beneath the stairs, including storage for art supplies and a chalkboard for impromptu masterpieces. Easy-wipe surfaces and fun accents invite regular use—and cleanup is a snap.

Install a pull-out pantry for bulk goods

This is different from the pull-out pantry idea mentioned above. Here you're optimizing for depth and weight. If you buy in bulk at Costco or Sam's Club, look for drawer slides rated for 100+ lbs (brands like Accuride or King Slide make heavy-duty options). Adjustable dividers let you reconfigure as your stockpile changes.

Lift bikes with under-stairs bike storage

Vertical wall-mounted hooks (the Steadyrack or Delta Michelangelo style) work well here because bikes hang flat against the surface and take up minimal depth. Line the area behind them with a sheet of hardboard or pegboard to protect drywall from handlebar dings. Helmets and gear can go on pegs or a small shelf above.

Add a hidden safe or security storage zone

This is a more niche idea, but if you need secure storage for documents, firearms, or valuables, a concealed panel under the stairs is hard to beat. The key is making the door blend with the surrounding trim and paneling. A push-latch with no visible handle keeps it discreet. Pair it with a fireproof safe inside for the important stuff.

Grow an indoor garden or plant display

Dedicate the under-stair area to built-in shelving or hanging planters for an indoor garden moment. Keep in mind, these areas don't usually get much natural light, so stick with low-light species (pothos, snake plants, ZZ plants) or install a grow light strip on each shelf. Trailing varieties on the upper shelves look especially good as they spill down alongside the stair angle.

Practical tips for under-stairs storage that works

Turning under-stairs space into storage is a smart move—but to make the most of it, it’s important to keep a few essential remodeling tips in mind:

• Plan for accessibility - Make sure every inch is reachable and usable, not just the front row. Opt for pull-out shelves, drawers, or bins to avoid deep, hard-to-access dead zones, and don’t forget to account for door swings and stairs’ slope in your design.

• Think about ventilation and lighting - Under-stair spaces can be dark and stuffy, so incorporate LED strip lighting, motion sensors, or puck lights to keep everything visible. If you're storing shoes, cleaning supplies, or laundry, plan for a bit of ventilation to prevent odors and moisture buildup.

• Maximize with custom solutions - Off-the-shelf organizers rarely fit the angled shape under stairs. If the budget allows, cabinetry or millwork measured to your exact dimensions is worth it. You'll use significantly more of the space than with stock pieces, while also being able to configure the under-stairs area precisely to your unique ideas. 

• Choose durable, easy-clean finishes - Under-stairs storage is in a high-traffic zone. Handle moisture, mud, and daily use with finishes that are scratch-resistant and easy to wipe down—think painted MDF, melamine, or sealed woods, especially for mudroom or laundry alcoves.

• Blend storage with your design style - Integrate the under-stairs area into your home’s aesthetic with paint colors and hardware finishes that match surrounding cabinetry and walls. Built-in storage should feel like an extension of your home—not a last-minute afterthought.

• Consider future needs - The best under-stairs remodels remain functional as your family grows or changes. Opt for adjustable shelves, mix open and closed storage, and leave room for shifting needs. Think about resale, too—well-designed storage adds major appeal.

How to determine if your stairs can accommodate built-in storage

Not every staircase is a good candidate. Before you sketch out under stairs shelving ideas, spend 20 minutes with a tape measure.

• Measure the "usable triangle." You need three numbers: the height at the tallest point, the total depth from front to back, and the width between walls. In a home with 8- to 9-foot ceilings, that tall end is typically 7 to 8 feet high, and the depth runs 8 to 12 feet depending on pitch. Below about 4 feet of headroom, the remaining area only fits low drawers or pull-out bins.

• Check for obstacles. Open any existing access panel and note electrical panels, gas meters, HVAC ducts, or plumbing runs. These are common under-stair tenants, especially in older homes. Remember, an electrical panel needs 36 inches of clear space in front of it per code.

• Determine whether the walls are load-bearing. Walls underneath a staircase can be structural, particularly if they run perpendicular to the floor joists or help support a landing. Signs: 2x6 studs instead of 2x4s, doubled-up top plates, or solid blocking above. Cutting into a load-bearing wall without a proper header can compromise your floor framing. 

Consider your stair type

• Straight stairs offer the most volume and the simplest execution for built-in storage. The full triangle is accessible from one side, making deep pull-outs, closets, and pantry conversions all viable.
• L-shaped and U-shaped stairs split the cavity into smaller zones divided by a landing. Drawers and cubbies work better here than deep closets.
• Open or floating stairs have no enclosed cavity. You're limited to freestanding furniture or shelving beneath the treads, and everything you add will be fully visible.
• Basement stairs often have lower ceilings (around 7 feet) which can work for simple shelf storage.
