Quick Answer: An ADA-accessible (Americans with Disabilities Act) or aging-in-place bathroom remodel in San Jose costs $12,000-$35,000 for a full conversion — this includes a zero-threshold roll-in shower (no curb) with fold-down bench and grab bars, raised/comfort-height toilet (17-19 inches), reinforced walls for grab bar mounting, 36-inch or wider doorway (ADA requires 32″ clear), floor-mounted or wall-hung vanity with knee clearance for wheelchair access, and non-slip tile flooring. Individual accessibility upgrades cost less: grab bar installation alone is $200-$600 per bar (including blocking and hardware); a comfort-height toilet replacement is $400-$900. The most impactful accessibility upgrades for aging-in-place in order of cost-effectiveness: (1) grab bars in shower/tub and near toilet; (2) remove tub curb and install roll-in shower; (3) non-slip flooring; (4) widen doorway to 36 inches.
