An aging in place bathroom remodel modifies the highest-risk room in the home for falls. The core changes — grab bars, a walk-in shower, a comfort-height toilet, and non-slip flooring — cost $2,700 to $16,000 depending on scope. This guide covers what to prioritize, what each component costs, and how to fund it.
The bathroom is the most dangerous room in the home for older adults. Wet surfaces, tight spaces, transfers on and off the toilet and in and out of the tub, and hard fixtures all contribute to fall risk. According to the CDC, falls are the leading cause of injury and injury death among adults 65 and older, and the bathroom is one of the most common sites. Modifying the bathroom first — before the kitchen, before the entryway — is the most effective single step most families can take.
The good news is that the most impactful modifications are also the least expensive. Grab bars at $200 to $350 each address the biggest risk. A handheld showerhead at $75 to $350 allows seated showering. Non-slip flooring or a quality mat costs $300 to $1,400. These three items, installed in one visit, can transform a dangerous bathroom for under $1,500.
Grab bars, a handheld showerhead, a raised toilet seat or comfort-height toilet, non-slip mats, and a shower chair. No permits, no demolition, same-day installation for most items. This is the starting point and may be all that is needed for someone who is steady on their feet but wants to reduce risk.
Removes the bathtub and installs a walk-in shower. This eliminates the need to step over a tub wall — one of the highest fall risks. A prefab acrylic shower costs $1,500 to $5,000; a custom tiled shower costs $4,500 to $15,000. Requires a plumbing permit in most cities. Installation takes 2 to 4 days for tile and 2 to 3 days for prefab panels.
According to Angi (2026), the average walk-in shower costs $6,000 to $12,000, with a $9,000 average. A curbless (roll-in) shower that allows wheelchair access costs more — $3,000 to $15,000 — because it requires a recessed floor, extended waterproofing, and a linear drain.
A walk-in tub has a water-tight door that opens so the person can step in without climbing over a wall. Best for people who want to soak and can tolerate a 10 to 20 minute fill and drain time. Costs $4,000 to $22,100 installed. A walk-in shower is usually the better choice for most seniors because it is faster, easier to clean, and less expensive, but a walk-in tub may be right for someone who values soaking and has the patience for the fill time.
Combines a walk-in shower, grab bars, comfort-height toilet, non-slip flooring, widened doorway, lever handles, and possibly a roll-in shower. May involve moving walls, relocating plumbing, or expanding the bathroom footprint. According to HomeAdvisor (2026), an accessible bathroom remodel averages $8,400. Structural work like widening a doorway adds $700 to $8,000 per door.

A full accessible bathroom remodel costs $2,700 to $16,000, with an $8,400 average, according to HomeAdvisor (2026). A tub-to-shower conversion runs $1,500 to $15,000, grab bars add $200 to $350 per bar, a comfort-height toilet costs $350 to $900, and non-slip flooring adds $300 to $1,400. Costs vary by scope, materials, and whether structural work is needed.
A tub-to-shower conversion removes the bathtub and installs a walk-in shower in its place. It costs $1,500 to $8,000 for a prefab unit or $4,500 to $15,000 for a custom tiled shower. It eliminates the need to step over a tub wall, which is one of the highest fall risks in the home.
A walk-in shower is usually the better choice for most seniors because it is faster to enter, easier to clean, and less expensive ($1,500 to $15,000 vs $4,000 to $22,100 for a walk-in tub). Walk-in tubs are better for people who want to soak and can tolerate a 10 to 20 minute fill and drain time. An occupational therapist can help you compare based on the person's mobility and preferences.
A curbless shower has no threshold — the floor is level with the bathroom floor, so a wheelchair or walker can roll straight in. It requires a sloped floor and waterproofing that extends beyond the shower area. A curbless shower costs $3,000 to $15,000 depending on size, tile, and whether the floor needs to be recessed.
Most bathroom remodels that involve moving plumbing, replacing a tub with a shower, or widening a doorway require a plumbing or building permit. Permit fees typically range from $250 to $500. Your contractor should pull the permit and arrange inspections. Working without a permit can cause problems when selling the home.
If you can only do one thing, install grab bars — at the toilet, at the shower entry, and on the shower back wall. They cost $200 to $350 each installed and address the highest fall risk in the highest-risk room. The second priority is a handheld showerhead ($75 to $350), which allows seated showering. The third is non-slip flooring or a non-slip mat.
