The bathroom upgrades that do the most for aging in place are grab bars anchored into studs or blocking, a handheld shower, a seat, lever handles, a comfort-height toilet, brighter lighting and a slip-resistant floor. Most are small jobs; our planning range for a grab bar is $110–$250 per bar. A low-curb or curbless shower is a remodel.
The upgrades at a glance
The National Institute on Aging's room-by-room advice for the bathroom is short: grab bars near the toilet and on both the inside and outside of the tub and shower, nonskid surfaces wherever it gets wet, and a light left on at night or a night light that turns on by itself (NIA). The table adds the rest of a bathroom built to be used for decades, from the quick jobs to the remodels.
| Upgrade | Why it helps | Complexity |
|---|---|---|
| Grab bars at the toilet and tub | Something solid to hold while sitting, standing and stepping over the tub edge | Small job when the bars land on studs or blocking |
| Handheld shower on a slide bar | Lets you shower seated and aim the water where you need it | Small job; usually no wall opening |
| Shower seat or bench | Takes standing out of the equation for anyone who tires or feels dizzy | Small for a fold-down or freestanding seat; larger for a built-in bench |
| Lever faucet and door handles | Work with a closed fist or an elbow, no tight grip or twist | Small job; a faucet swap needs no permit if the supply isn't altered |
| Comfort-height toilet | A higher seat means less of a squat to sit and less push to stand | Small to moderate; depends on the flange and floor |
| Brighter light and night lights | Fewer trips over what you can't see at 3 a.m. | Plug-in night lights are simple; a new fixture needs an electrician and permit |
| Slip-resistant floor | Better footing on a wet floor | Moderate; new flooring over a sound subfloor |
| Low-curb or curbless shower | No high tub wall to step over | Major; a remodel with a building permit in Duluth |
Start with the small jobs. Grab bars, a handheld shower and a night light can go in on one visit and change how the room feels right away. Save the shower rebuild for when the tub is truly the obstacle, or when the bathroom is due for a remodel anyway.
Where grab bars go, and how high
The ADA standards apply to public and commercial buildings rather than private homes, but they're a well-tested reference for where a grab bar goes. The U.S. Access Board's guide puts grab bars 33 to 36 inches above the floor, measured to the top of the bar, with exactly 1-1/2 inches between the bar and the wall, strong enough to resist 250 pounds (U.S. Access Board). At a toilet, its side-wall bar is at least 42 inches long, starts no more than 12 inches from the back wall and runs at least 54 inches out from it.
At a tub, the same standards add a second, lower bar on the back wall, 8 to 10 inches above the rim, for pushing up from a seated bath (U.S. Access Board). In a real home, adjust for the person: a vertical bar at the tub entry suits someone who steps in standing, and a shorter or taller person may want the horizontal bars nudged. An occupational therapist's placement notes beat any chart.
The 250-pound figure is why anchoring matters. A bar is only as strong as what's behind it, so screws go into studs or wood blocking. If the walls are open for a remodel, add blocking now along every wall near the toilet, tub and shower, and photograph it before the wall closes, so future bars can go exactly where they're needed.
Curbless or low-curb shower
Stepping over a tub wall with wet feet is one of the hardest moves in a bathroom. Replacing the tub with a shower solves that, and the question becomes how low the entry should be. The Access Board's transfer shower allows a threshold of no more than 1/2 inch; a true curbless shower has none. Both need the floor inside to slope to the drain without the water running out.
A curbless shower suits a wheelchair or walker, but it means recessing the floor inside the shower, which older Duluth framing doesn't always allow. A low-curb shower, with a curb a few inches high, works with most existing floors and is far easier to step over than a tub. Either way, add a handheld shower on a slide bar with a long hose (the Access Board calls for at least 59 inches), a seat, and bars on the walls you'll reach for. Unless the slide bar is sold as a grab bar, nobody should lean on it. In Duluth, replacing a tub with a shower needs a building permit; see shower remodeling for how the conversion works.
Toilet, handles, light and floor
Toilet. The Access Board's guide sets toilet seats at 17 to 19 inches, measured to the top of the seat, and so-called comfort-height toilets are built in that range. Our planning range to install a toilet is $150–$300, plus the fixture.
Handles. The ADA standards ask for controls that work with one hand, without tight grasping, pinching or twisting of the wrist. Lever faucets and lever door handles meet that idea; round knobs don't.
Light. Brighter light over the vanity and in the shower helps every day, and a plug-in night light helps at night. A new fixture or a new switch location is electrical work: in Duluth, installing new light fixtures, switches or outlets needs an electrical permit (City of Duluth), and a licensed electrician does it.
Floor. Small tiles with more grout lines, or a textured tile, give better footing than large polished tile. Whatever the floor, a nonskid mat in the tub and a rug with a rubber back outside it are cheap insurance.
What height should grab bars be installed at?
A good starting point is 33 to 36 inches above the floor, measured to the top of the bar, which is the range the ADA standards use for public buildings. At a tub, a second bar 8 to 10 inches above the rim helps with standing up from a bath. In a home, adjust to the person who uses it, and anchor every bar into studs or blocking.
Is a curbless shower better than a low-curb shower?
For a wheelchair or a walker, yes; for most people who can step, a low curb works nearly as well for less money. A curbless shower means recessing the floor inside the shower, which older framing doesn't always allow. A low curb a few inches high sits on the existing floor, keeps water in more easily, and is still far easier to step over than a tub wall.
What is a comfort-height toilet?
A comfort-height toilet has its seat higher than an older standard toilet, in the 17- to 19-inch range the ADA standards use for accessible toilets. The higher seat means less of a squat to sit and less push to stand, which helps anyone with sore knees or hips. Replacing a toilet without altering the water supply needs no plumbing permit in Duluth.
