A one-day install is not a one-size install. Niches, a bench, grab bars, and a properly placed handheld all get built into the assembly. The important thing to understand is the timing: because these are integrated as the wall is built up, they are specified at the free measure. Adding a recessed niche after the panels are sealed means opening the wall again, which is a different job entirely.

So it is worth thinking about all of it once, properly, before install day.

Recessed niches

A recessed niche is a shelf set into the wall rather than hung on it. It replaces the suction caddy that falls down and the bottles that end up on the floor where you have to bend for them.

Placement. Between forty-eight and sixty inches above the floor is the useful range: reachable without stretching and without bending. If anyone will be using a seat, add a second niche at seated reach.

Size. Bigger than people expect. A niche needs to accommodate a tall shampoo bottle standing upright, so aim for at least twelve inches high in the clear. A common regret is a niche sized to look elegant that will not hold a conditioner bottle.

Position relative to the door. On the wall away from the shower opening, so it is not the first thing you see, and never directly behind the shower head where it takes the full spray.

Two smaller niches often work better than one large one if two people share the shower, because it removes a daily negotiation.

Benches and seats

A seat changes the character of a shower. It turns standing endurance into something comfortable, and it makes washing your feet and legs safe rather than a balance manoeuvre.

Height. Seventeen to nineteen inches above the finished floor, which is ordinary chair height and therefore an easy sit and an easy stand.

Depth. At least fifteen inches to be genuinely usable. A shallow ledge is a place to rest a foot, not a seat.

Built-in versus fold-down. A built-in bench is more substantial and more comfortable, and it consumes floor space permanently. A fold-down seat preserves the full floor for anyone who does not need it. In a compact bathroom the fold-down usually wins; in a larger space the built-in is nicer to use.

Placement. On the wall opposite or perpendicular to the shower head, so you are not sitting directly under the spray, and within reach of the valve and the handheld.

Grab bars, and the mistake almost everyone makes

This is the item where installation quality matters more than product selection, and where we see the most dangerous work.

A grab bar must be anchored into solid blocking behind the wall surface. Drywall anchors, plastic toggles, and self-drilling wall plugs are not adequate, regardless of what the packaging claims. A bar takes its load suddenly, from someone already losing balance, and a fastener that pulls out at that moment turns a stumble into a fall with a metal bar in the person's hand.

The reference figures worth using: mounted thirty-three to thirty-six inches above the floor, bar diameter between one and a quarter and two inches, one and a half inches of clearance to the wall so a hand can wrap fully around it, and an assembly rated to resist a 250 pound point load.

The advice we give everyone: have blocking set even if you do not want the bars now. It costs almost nothing while the wall is open, it is invisible once the panels are on, and it means bars can be added in an hour at any point in the next twenty years instead of requiring the wall to come apart. Nobody has ever regretted having blocking they did not use.

Placement. One vertical or angled bar at the entry for the step in and out. One horizontal bar on the long wall for support while standing. If there is a seat, one within reach of it for the sit-to-stand transition.

The rest of it

  • Handheld on a slide bar. The most useful single fixture upgrade. Allows seated washing, makes rinsing the shower itself easy, and makes assisted bathing dignified.
  • Lever handles rather than knobs. Operable with a forearm or a closed fist, which matters for arthritic hands.
  • Thermostatic or anti-scald valve. Prevents the sudden temperature change that causes a startle and a slip, and protects thinner older skin from a burn.
  • A curtain instead of a door, sometimes. Worth genuinely considering, for reasons covered in our guide on shower doors versus curtains.
  • Lighting. A dedicated shower light transforms a dim alcove. Inexpensive during a remodel, awkward afterwards.

Decide once, at the measure
