Aging-in-Place & Accessible Walk-In Showers Phoenix

Key takeaways

RDC builds blocking for grab bars into the wall before the tile goes on, so bars can be mounted securely later.
A tub-to-shower conversion takes 5 to 8 working days of construction when the drain stays where it is.
A roll-in shower has no curb at all, so a shower chair or wheelchair can roll straight in.
Original Medicare does not cover grab bars or bathtub seats, which CMS lists as not primarily medical.
The in-home measure and the written estimate are free, and every job carries a 1-year workmanship warranty.

What Does an Aging-in-Place Bathroom Include?

An aging-in-place bathroom includes a curbless or low-step shower, solid blocking for grab bars, slip-resistant floor tile and a place to sit. RDC plans each of these as part of its Phoenix bathroom remodeling work. These are the five features RDC builds in:

Curbless or low-threshold walk-in shower: removes the step over the tub wall.
Grab-bar-ready walls: we reinforce the walls during the remodel so bars mount securely wherever you need them.
Slip-resistant floor tile: textured tile chosen for wet floors, in the shower and on the bathroom floor.
Built-in bench or seat: a tiled bench for seated bathing, integrated into the shower.
Wider, easier entry: a more open shower layout that works with a walker or wheelchair where the space allows.

Why the Step-Over Tub Is the First Thing to Go

RDC Renovation & Design Concepts is a bathroom remodeling contractor in Phoenix, Arizona. Climbing over a tub wall is the step a walk-in shower removes. Converting that tub to a curbless or low-threshold walk-in shower is one of the most practical changes for aging in place.

RDC rebuilds the shower pan with a bonded waterproofing membrane (Schluter KERDI or RedGard). The entry then sits flush, or nearly flush, with the bathroom floor. RDC then finishes the shower in slip-resistant tile. The result looks like a modern spa shower, not a hospital room.

"Take out the step into the tub, put blocking in the wall for grab bars before the tile goes on, and add a bench. Those three things are what let people keep living in their own home." Eli Kovalev, Owner, RDC Renovation & Design Concepts

How Much Does a Walk-In Shower for Seniors Cost in Phoenix?

A walk-in shower for seniors in Phoenix costs $9,000 to $14,000 at RDC when a tub becomes a tiled, low-threshold shower. A curbless entry usually adds about $3,000, depending on the existing floor and drain. Converting a jetted tub, or combining a garden tub and a separate shower into one shower, adds about $3,000 to $5,000.

A full small bathroom remodel starts at $9,000. Final pricing is set individually for each customer based on their specific project, confirmed in a free written estimate.

Example: a hall-bath tub becomes a low-threshold tiled shower with a built-in bench, grab-bar blocking and a handheld shower valve. It is priced from the tub-to-shower range above in the free written estimate. Full price tables are in the bathroom remodel cost guide for Phoenix and on the walk-in shower installation in Phoenix page.

Walk-In Shower vs Roll-In Shower: Which Do You Need?

A walk-in shower with a low threshold and a bench suits someone who can step in or slide across to a seat. A roll-in shower has no curb, so a shower chair or wheelchair rolls straight in. The ADA Standards and ICC A117.1 reference sizes are 36 by 36 inches for transfer and 30 by 60 inches minimum for roll-in.

The same references put grab bars 33 to 36 inches above the floor and a seat 17 to 19 inches high. What a specific bathroom can meet depends on the room. RDC tells you at the in-home measure which sizes fit, and a roll-in shower needs the curbless build priced above.

The full reference table, including the turning space, is on the accessible walk-in shower guide.

Does Medicare Pay for a Walk-In Shower?

Medicare.gov's equipment list and the CMS reference list do not name a walk-in shower. Part B covers medically necessary durable medical equipment that a doctor orders. Medicare.gov defines it as durable, used for a medical reason, used in your home and expected to last at least 3 years.

The CMS reference list (NCD 280.1) denies grab bars and bathtub seats as not primarily medical in nature.

Coverage rules change, so check Medicare.gov or call 1-800-MEDICARE before you count on any payment. RDC's written estimate lists each part of the work. For every bathroom scope RDC handles, see bathroom remodeling in Phoenix.

Arizona and Phoenix Conditions That Shape an Accessible Shower

In Arizona, Medicaid is AHCCCS. Its policy 1240-I covers home modifications for members of its long-term care program, ALTCS, when an assessment shows the need. The FAQ below sums up what that policy requires.

City of Phoenix water runs 10 to 17.6 grains per gallon of hardness in the City of Phoenix 2025 report. Hard water leaves mineral film on glass and grout. RDC chooses the grout for each area, cement-based, sealed or epoxy, with the hard water in mind.

RDC's showroom is at 1610 E Bell Rd Suite 101 in North Phoenix, where you can see the tile and fixtures before choosing. Converting the original tub to a walk-in shower is the most requested change in Sun City. RDC builds tub-to-shower conversions across the Valley.

The installers we work with keep clean, clearly scheduled job sites and treat your home with respect. For Sun City West specifically, the Sun City West bathroom remodeling page covers costs, grab-bar blocking and permits.

FAQ

Aging-in-Place Bathroom Questions in Phoenix, AZ

An aging-in-place bathroom remodel changes a bathroom so you can keep using it safely as you get older. At RDC the work centers on the shower. The step-over tub comes out and a low-threshold or curbless shower goes in. RDC handles the tile, shower and layout work.

Yes, curbless (zero-entry) and low-threshold walk-in showers are a core part of RDC's bathroom work. We build the shower pan, waterproofing and tile so the entry is flush or nearly flush with the floor. We also install slip-resistant floor tile.

Yes. We reinforce the walls with solid backing during the remodel, so grab bars can be mounted securely exactly where they're needed. We can also build in a tiled bench or seat. Backing added at the tile stage gives each bar solid framing behind it, and it stays hidden behind the tile.

Medicare's booklet does not list walk-in showers. Medicare Advantage Plans must cover the same medically necessary categories of DME items as Original Medicare. Suppliers and your costs depend on the plan, and the booklet says to contact it. Ask the plan in writing before work starts.

In Arizona, Medicaid is AHCCCS, and its policy 1240-I covers home modifications for members of ALTCS, its long-term care program. One example it names is the modification of one bathroom, such as a roll-in shower. The policy lists a PCP or physician order and an assessment, usually by an occupational or physical therapist. General home improvements are excluded, so ask your ALTCS plan.

Yes, RDC builds accessible walk-in showers and tub-to-shower conversions from its Phoenix Bell Rd showroom. It serves Sun City, Sun City West, Surprise and other Valley cities. The in-home measure and the written estimate are free. We keep clean, clearly scheduled job sites.
