Decide these while the walls are open
- 1Shower entry: curbless, low-profile or standard curb
- 2Continuous blocking across shower, toilet and any bench walls
- 3Doorway width, and whether the door swings out or slides rather than in
- 4Clear floor space in front of the toilet, vanity and shower
- 5Shower size — enough depth for a helper alongside, if that is foreseeable
- 6Floor structure work needed for a level entry or a linear drain
These can be added when they are needed
- Grab bars, once blocking exists
- A hand-held shower on a slide bar
- A removable transfer bench
- Lever handles in place of knobs
- A comfort-height toilet
- Additional task lighting
Surfaces, controls and light
Slip resistance on a wet floor is a property of the tile — its texture and its format. Smaller tiles mean more grout lines and more grip underfoot, which is why mosaic remains standard on shower floors. Aftermarket anti-slip coatings are a workaround for a floor that was chosen wrong.
Lighting is underrated. A single ceiling fixture puts the user's own shadow exactly where they are looking, and leaves the shower interior dim. A damp-rated light inside the shower, task light at the mirror from both sides, and a low-level night light between them make far more practical difference than most hardware.
Thermostatic or pressure-balancing valves are worth specifying where scald risk is a concern, and putting shower controls near the entry means the water can be started without standing under it.
