Bathroom Remodeling
ADA Accessible Bathrooms
Grab bar blocking installed within wall studs provides essential structural support for secure grab bar attachment. This hidden framework is a critical step in creating an ADA accessible bathroom, addressing floor space, fixture heights, and barrier-free shower access.
Key Elements of an Accessible Bathroom Remodel
An accessible bathroom remodel involves more than adding grab bars. Core elements include ensuring a 60-inch turning radius for full wheelchair rotation where layout allows. Walls around a shower or toilet require solid blocking (2x10 or 2x12 lumber between studs) before finishes, ensuring grab bars have a reliable anchor. Fixtures are selected for accessibility, such as comfort-height toilets (17 to 19 inches from floor to seat) and sinks open underneath for wheelchair knee clearance.
For showering, options include roll-in or low-threshold entry. A roll-in shower has a sloped floor for wheelchair entry without a curb, demanding careful waterproofing. Low-threshold showers reduce the lip to 1/2 inch or less. In older New England housing like triple-deckers, a full 60-inch turning radius can be challenging.
When an Accessible Remodel is the Right Solution
A full ADA accessible bathroom remodel is generally needed for significant mobility accommodations, such as wheelchair access, or for long-term aging in place. This project type exceeds simple modifications like a single grab bar. If only minor assistance is needed, a grab bar installation with a non-slip mat might suffice. However, if a user needs to navigate in a wheelchair or transfer, a comprehensive remodel is more suitable.
For smaller bathrooms in homes like postwar capes, a full remodel might reconfigure the entire space, potentially using square footage from an adjacent closet. Surface-mounted grab bars without internal blocking or a temporary ramp into a standard shower will not meet ADA guidelines or provide durable support.
Estimating Time for ADA Bathroom Projects
The duration for an ADA accessible bathroom remodel varies based on scope and existing structural conditions. A straightforward tub to roll-in shower conversion within the existing footprint might take 10 to 15 working days, including demolition, blocking, plumbing, waterproofing, tile, and fixture setting. Projects requiring significant floor plan alterations (e.g., moving walls for a 60-inch turning radius, or modifying joists for a roll-in shower slope) will extend this timeline.
In older New England homes, checking joist direction and door width is crucial. Widening a door from 24 or 28 inches to 32 or 36 inches for wheelchair access can add several working days. Complex projects with wall reconfiguration and extensive plumbing could reach 20 to 30 working days. Unforeseen conditions in older housing, like plaster and lath demolition, can also add time.
Cost Drivers for Accessible Bathroom Remodels
The cost of an ADA accessible bathroom remodel reflects structural changes, fixture choices, and the complexity of meeting accessibility standards. While general bathroom remodeling in Massachusetts ranges from $9,500 to $28,000 for a tub to shower conversion through a full remodel, an accessible project often falls into the higher end or exceeds this range. Adding a roll-in shower with specific subfloor preparation and waterproofing adds expense. Modifying wall structures for grab bar blocking is standard, but widening doorways or moving walls significantly increases labor and material costs.
Specialized accessible fixtures like comfort-height toilets or roll-under sinks are generally minor cost drivers compared to labor for structural and plumbing alterations. The main cost factors are usually reconfiguring the layout for turning radius requirements and altering door openings.
Risks of Improper Accessible Bathroom Installation
Improper installation of an ADA accessible bathroom can create safety hazards and premature failures. A common issue is grab bars installed without adequate in-wall blocking. If screwed only into drywall or thin studs, they may pull away under weight, causing falls, especially in older homes with plaster over lath. Another failure point is insufficient waterproofing in roll-in showers. If the sloped floor and wall connections are not correctly sealed, water can leak into the subfloor, leading to rot in joists and framing.
Doorways widened without proper header support can compromise wall structure. Incorrect fixture placement can still create barriers; a grab bar at the wrong height might be unusable. A shower bench not securely fastened or made from water-resistant materials can fail over time.
Common questions
A 60-inch turning radius refers to a clear, circular floor area 60 inches in diameter. This space allows a person using a wheelchair to turn 360 degrees without obstruction, a key ADA guideline for accessible bathrooms.
Yes, many older New England houses, including center chimney colonials and triple-deckers, can be adapted. Constraints often involve existing door widths and floor joist direction, requiring adjustments like widening doorways or reconfiguring layouts.
Comfort-height fixtures are toilets and vanities designed taller than standard versions for easier use by individuals with mobility limitations. Comfort-height toilets are typically 17 to 19 inches from the floor to the seat, compared to standard heights around 14 to 15 inches.
No, while roll-in showers are primary for wheelchair users, low-threshold showers are also available. These feature a minimal curb, usually 1/2 inch or less, suiting individuals using walkers or with limited mobility.
