Climbing over a tub wall, lowering yourself onto a low toilet, reaching for a towel bar that was never meant to hold weight: these get harder over time, and the bathroom is often where it shows up first. An accessible remodel makes practical changes that work for everyone in the house, whether you’re planning ahead or adjusting to a change now.

A shower you can walk into

The biggest change is usually replacing a tub with a shower that has a very low curb or none. A standard tub alcove is a good starting point: the ADA standards, which are written for public buildings rather than homes, set a roll-in shower at a minimum of 30 by 60 inches, entered along the full 60-inch side, which is about the footprint of a standard tub. Our page on tub-to-shower conversions covers what that swap involves.

A curbless entry is the easiest to roll or walk into, but it requires lowering the floor in the shower area, which is evaluated during the in-home consultation. A low curb is simpler and still far easier than a tub wall. Our side-by-side look at curbless and standard showers weighs the two.

Inside, plan for a handheld shower on a slide bar with a hose at least 59 inches long, the length the ADA standards specify, a fold-down or built-in seat 17 to 19 inches high, and controls placed by the entry, within reach before you step into the spray. California already requires pressure-balancing or thermostatic valves on showers, with the water limited to 120 degrees at the showerhead. A thermostatic valve also lets you set a preferred temperature once and leave it there.

Blocking now, grab bars when you want them

Grab bars have to be anchored to solid wood, not drywall. While the walls are open, solid blocking can go in around the toilet, shower and tub, so bars can be installed now or later in the right places.

California now requires this kind of backing in at least one bathroom of new homes, using 2-by-8 lumber between 32 and 39-1/4 inches above the floor. Remodels aren’t required to follow that rule, but it’s a sensible pattern to copy. The ADA standards place grab bars 33 to 36 inches above the floor, and some bars are designed to double as towel bars or shower shelves.

Toilet, vanity and floor

A comfort-height toilet puts the seat at 17 to 19 inches, the range the ADA standards use, a few inches higher than many standard bowls. Blocking on the wall beside it leaves room for a grab bar. If you want a bidet seat, it needs a ground-fault-protected outlet near the toilet, which is electrical work confirmed during the consultation.

A wall-hung vanity mounted at a comfortable height, or a vanity with open knee space, works for someone who is seated. A mirror that extends down toward the counter, or one that tilts, serves both standing and seated users. Lever handles on faucets and doors are easier to operate than round knobs.

Underfoot, matte or textured tile rated for wet floors gives better footing, and smaller tiles with more grout lines help inside the shower. Our bathroom flooring page explains slip-resistance ratings.

Room to move and light to see

If a wheelchair or walker is part of the picture, the ADA standards use a 60-inch circle as turning space. Many existing bathrooms can’t provide that without moving walls, which calls for a structural review at the consultation, but rearranging fixtures and changing how the door swings can gain usable floor.

Door width matters as much as floor space. California’s rules for new homes call for a 32-inch net clear opening on at least one bathroom door on the entry level. In an existing home, offset hinges that swing the door clear of the opening gain some width without touching the wall, while a true widening is a wall change evaluated during the consultation.

Brighter, even lighting, a lighted switch or night light by the door, and contrasting colors at counter edges and the shower entry make the room easier to use after dark. Adding or moving lights is electrical work reviewed at the consultation. Our aging-in-place bathroom checklist lists more details to consider.

Using the estimator for an accessible remodel

Choose your bathroom size, then “Tub to Walk-In Shower” if a tub is coming out or “Custom Tile Shower” for a rebuilt shower with a low or no curb. A curbless entry that needs the floor lowered counts as a layout change, minor or major depending on scope, and moving the toilet or widening a doorway is “Major Layout Changes.” Blocking, lever handles and a comfort-height toilet don’t have their own question, so mention them at the consultation.

As a frame of reference, a typical bathroom remodel with us lands around $25,000, and projects generally start around $15,000. Blocking and lever handles fit easily inside a standard remodel, while lowering a floor for a curbless shower or changing the layout moves a project toward the larger band of $30,000 to $40,000. Your bathroom estimate is the first step.

Planning the work around the people who use the room

At the consultation, describe who uses the room and what’s hard today. If an occupational therapist or doctor has recommended specific features, bring those notes. Measurements, floor structure for a curbless shower, door widths and permit needs are confirmed in person, and you’ll have a plan and schedule in hand before work starts.

If you’re remodeling for other reasons, adding blocking and choosing a low-curb shower now is far easier than opening finished walls later. See the full range of bathroom remodeling work for everything else a project can include.
