A curbless shower can remove a difficult step and make bathing easier with a walker, wheelchair, shower chair, or caregiver. It can also fail in frustrating ways when the entrance is technically flat but the room floods, the transfer space is misplaced, or the controls cannot be reached.
Before choosing tile, settle the functional and construction decisions that determine whether the shower will work.
1. Who will use the shower—and how?
Identify whether the person will walk in, roll in, transfer to a bench, or use a rolling shower chair. Document balance, endurance, reach, vision, cognition, skin needs, and the help a caregiver provides. The design should fit the real bathing routine rather than an imagined “accessible” user.
2. What is the complete route?
Check the bedroom-to-bathroom path, door swing, turning points, floor transitions, toilet location, and where mobility equipment will wait. Removing the shower curb does not solve a narrow doorway or a tight turn outside the room.
3. Where will transfers happen?
A side transfer to a bench needs a different clear space from a standing pivot. If a ceiling lift or caregiver assistance may be needed, include the track path and caregiver stance before fixing walls, glass, or plumbing.
4. How will the floor drain?
A qualified team should coordinate the shower footprint, floor slope, drain location, waterproofing, and transition into the bathroom. Water should move toward the drain without creating a steep cross-slope or a lip that catches small wheels.
5. Where do controls, spray, and storage belong?
Place the valve, handheld shower, shelf, towels, and soap where the user or caregiver can reach them from the expected position. A handheld shower should have a practical resting point, and the spray direction should not send water across the dry area.
6. What support may be needed later?
Install structural blocking where grab bars, fold-down seating, or other supports may be placed. The final location should be chosen from the user’s transfer and standing pattern—not a generic row of bars.
7. How will privacy and caregiver access coexist?
Fixed glass can restrict assistance or equipment. Compare curtains, partial panels, doors, and open designs by water control, reach, cleaning, and caregiver space.
8. Who owns the waterproofing and permit scope?
Ask the contractor to identify the waterproofing system, testing method, ventilation work, plumbing and electrical responsibilities, permits, and warranty in writing. The Hawaiʻi DCAB design resources are useful references, but the applicable requirements depend on the property and scope.
Design the shower around the task
A successful curbless shower connects the person’s movement with drainage, structure, fixtures, and the rest of the room. Thrive for Life’s complimentary OT assessment can help define those requirements before remodeling begins.
