Working With the Occupational Therapist
Why this matters
On a growing share of accessibility jobs there is a third professional in the room: an occupational therapist who has already assessed the person and written down what the house should do for them. That recommendation is the best information you will get about the person's function, and it often arrives with dimensions that the structure cannot deliver. Shops go wrong in two directions. Some build the recommendation literally, including the parts that will not work in that bathroom. Others quietly substitute something easier, and the person gets a modification no clinician has looked at. Both are avoidable once you know where the OT's job ends and yours begins.
What an OT does, and what they do not
An occupational therapist (OT) is a licensed health professional who works on the tasks of daily life. Every state licenses OTs; the license title and scope wording vary by state. In home modification work, the OT assesses the person's activities of daily living (ADLs) - bathing, toileting, dressing, moving between surfaces (called transfers), getting in and out of the house - and recommends equipment, technique changes and modifications so those tasks are safer or possible.
A physical therapist (PT) overlaps but leans toward strength, balance and walking. An OT is the one who watches someone get from a wheelchair to a toilet and decides which side the grab bar goes on and why.
What an OT does not do is assess the building. They are not trained to know whether a joist is under the drain, whether a wall is bearing, or whether a shower can slope to its drain inside the floor depth available. A good OT says so in the report: "recommend contractor confirm feasibility." That sentence is your job.
| Question | Who answers it |
|---|---|
| What can this person do, and how will that change? | OT |
| Which side, what height, what clear space does their transfer need? | OT, with your measurements |
| Will this structure take it, and how? | Contractor |
| Does it need a permit, and does it pass? | Building official |
| Will a funding program pay for it? | The program, usually on the OT's recommendation |
| Does the finished work do what the person needs? | The OT, ideally at a visit after install |
| Is this what the person wants? | The person |
How to read a recommendation
OT reports are written for clinicians and funders first. Read each item for three things.
The functional goal. Behind every product or dimension is a task: "client to complete tub transfer independently using transfer bench," "caregiver to assist with showering from seated position." The goal is what you must deliver. The product is one way to deliver it.
What is specified versus what is generic. "Grab bar, right side wall, 34 in to top, client transfers to right" is specified from observation. "Grab bars per ADA" is a generic reference, and in a private home the 2010 ADA Standards are a dimensional reference, not a requirement (see related: What the ADA Does and Does Not Cover in a Private Home). Treat specified numbers as the client's numbers; treat generic ones as a starting point to confirm.
What the OT measured. Good reports record the wheelchair or walker dimensions, seated heights and the side the person transfers toward. If those are missing, ask; do not guess them from a product brochure. Your own walkthrough fills the structural half. See related: The Accessibility Walkthrough With the Person Who Lives There.
When the recommendation will not fit the structure
You will sometimes measure the room and find that an item cannot be built as written: the 60-inch turning circle needs a bathroom 18 inches wider than this one, the door is in a bearing wall, the floor will not allow a curbless drain. Four rules keep that conversation professional.
- Go back to the OT, not around them. Do not substitute a different solution and tell the family. The OT's recommendation may be part of a funding approval, and an unapproved change can cost the person the funding.
- Lead with the goal, not the problem. "I want to make sure I deliver the caregiver-assisted shower you're after" lands differently from "that won't work."
- Bring measurements and at least one alternative that serves the same goal, with what it gives up.
- Put the agreed change in writing, ideally as a revised recommendation from the OT, so the funder, the family and your file all show the same scope.
Worked example: the 60-by-60 shower in a 5-by-8 bathroom
An OT's home assessment for a woman who uses a manual wheelchair, 25 inches wide, and showers seated with help from her husband, recommends:
- Remove the tub; install a curbless roll-in shower, 60 by 60 inches, so the caregiver can assist from inside the shower.
- Raise the toilet to 17 to 19 inches; grab bars both sides.
- Widen the bathroom door to a 36-inch door.
The structure. The bathroom is 60 by 96 inches. The tub occupies a 60 by 30 inch alcove at one end, the toilet sits in a 30-inch space between the vanity and the side wall, and the door wall is a non-bearing partition. A 60 by 60 inch shower would take 60 of the room's 96 inches, leaving 36 inches for toilet and vanity along that length, which cannot hold a toilet with its clear floor space and a vanity.
Item 3 is buildable as written. The partition can be reframed for a wider door; the shop agrees it.
Item 2 needs one detail. "Grab bars both sides" in a 30-inch alcove means a fixed bar on the wall side and, on the vanity side where there is no wall, a swing-up bar mounted behind the toilet. That is still the recommendation, with the method spelled out. The shop confirms the swing-up bar's mounting needs backing in the rear wall and notes it.
Item 1 goes back to the OT. The goal is a seated, caregiver-assisted shower. The 60 by 60 size was there to give the husband room to stand beside his wife inside a curbed shower.
TECH: I measured the bath. Five by eight, tub on the
short wall. A sixty-by-sixty shower leaves three
feet for the toilet and vanity, and that won't go.
OT: The size was for her husband. He needs to stand
next to her while she's on the shower chair.
TECH: Then here's a way that keeps that. Curbless
shower, sixty wide by forty deep, and the whole
floor waterproofed and sloped, so he stands on
the bathroom floor right at the shower, not in
it. Wet-room style. She rolls straight in.
OT: Where's the handheld?
TECH: On a slide bar on the long wall, reachable by
him standing or her seated. Controls at the
entry side so he doesn't reach across her.
OT: That works for the goal. I'll revise the
recommendation and send it to the funder.
TECH: Thanks. I'll hold ordering until I see it.
Why the alternative fits. A 40-inch-deep shower along the 60-inch wall leaves 56 inches of the room's length (96 minus 40) for the toilet and vanity, where the 60 by 60 left 36. That is enough for the toilet's 30-inch alcove and a narrower vanity, and the 60-inch width still clears her 25-inch chair with room for the husband's hands at her side.
Why the alternative serves the goal. The husband's working space moves from inside the shower to the waterproofed floor beside it, which only works because the whole bathroom floor is treated as a wet area and slopes so water from the shower does not reach the hallway. That drainage is real work with its own failure mode. See related: Curbless Showers and Where the Water Goes.
What it gives up. The husband now stands on a floor that gets wet, so the floor finish must be slip-resistant when wet, and the bathroom will be wet after every shower. The OT accepted that; the person and her husband were asked and agreed.
What would have changed the answer. If the woman transferred to a tub bench rather than showering in her chair, the OT's goal would be different and a low-threshold tub-footprint shower might serve it without touching the floor depth. If the floor had been a slab with no room to recess, the curbless shower itself would come back to the OT as a question. If the funder had already approved the 60 by 60 scope, the revision would need to go through the funder before work began, and the shop would not start on its own revision.
Sign-off and handover
Agree before the job starts who checks what at the end. The building official signs off the permit work. The OT, where possible, visits after install and watches the person use the bathroom; that visit catches the bar an inch too far back or the shower control on the wrong side, and funders increasingly ask for it. The shop's sign-off is that the work matches the agreed recommendation and the structural notes, with photos of the blocking and the waterproofing before they were covered. Schedule the final invoice after the OT visit if the funder pays on completion, so a correction is a punch-list item rather than a dispute.
Finding and working with an OT when there is none
If a family calls with no OT involved and the person's function is changing or the job is large, recommend one. Hospital discharge planners, home health agencies and private-practice OTs all do home assessments, and a clinician's order may bring the visit under the person's health coverage; the OT's office will know. Area Agencies on Aging can usually name local providers. Your role is to say what the OT will add, not to arrange their care.
