Shower Size and Standing Room
Thirty six by thirty six inches is legal and almost nobody enjoys standing in it. The sizes recommended through walk in shower installation lakewood ca nexusphiladelphia start a foot larger in both directions, since a Lakewood shower has to hold a person, a bench, a door that opens and somewhere to put the soap down.
The Working Numbers
Thirty six inches square is the usual code minimum. Forty two by forty eight is noticeably better. Sixty by thirty six, the old tub footprint, is the most common size in an existing house and works well because the length gives a wet end and a dry end. Beyond about sixty by sixty, a single head no longer heats the space.
What a Bench Costs
A fifteen inch deep seat takes fifteen inches out of the floor, so a thirty six inch shower with a bench leaves twenty one inches of standing room, which is not enough. Either the shower grows or the bench becomes a folding seat. This is the calculation that catches out most small conversions.
Door Swings and Entry Width
A hinged glass door needs to open without hitting a vanity or a toilet, and it needs clear floor outside for the person doing it. Twenty two to twenty four inches of opening is comfortable, thirty two if the room has to be accessible. On a doorless design the opening is wider still, and the distance to the head grows with it.
Ceiling and Head Height
Eighty inches of clear height is the usual minimum, and a shower head at seventy eight needs more than that above it to look right. Under a sloped ceiling, position the head at the tall end and check that somebody standing at full height clears the low side. Height problems are found in elevation and never on a plan.
Two People
A shower used by two at once needs two heads, a wider footprint, and thermostatic control so one person adjusting the temperature does not affect the other. It also needs a drain sized and positioned for twice the flow. It is a genuinely different build rather than a larger version of the same one.
