Test the bathroom assumption
Stand in the proposed position during the day with the room lights off. Does the fern receive bright indirect daylight, or is it several metres from a small frosted window? A brief burst of shower humidity cannot turn a dark shelf into a suitable growing site. Also note whether the room becomes cold between uses. Choose the position from the combination of light, moisture and temperature rather than the room's name on a floor plan.
Reach the centre of the root ball
A dense fern can hide dry medium beneath a generous canopy. Lift fronds carefully and check moisture at the pot's centre as well as near the edge. Water thoroughly when needed, then allow excess to drain. Do not assume that damp-looking outer roots mean the whole root ball is hydrated. If water runs straight through a very dry or congested pot, investigate the medium and roots rather than increasing the frequency of superficial splashes.
Read the fronds individually
Old fronds eventually decline, while widespread crisping may point to a broader moisture or environmental problem. Trace a fully damaged frond to its base before removing it so emerging growth is preserved. Turn a healthy frond over and look for regular brown structures associated with spores; these should not automatically be mistaken for pests. If marks are irregular or the plant is declining, take clear photographs of both surfaces and inspect more closely before applying any treatment.
Make humidity a measurable question
If dry indoor air seems likely, a simple humidity reading near the plant can be more useful than repeated misting. Keep the fern away from strong heating airflow and provide suitable room humidity where practical, while retaining air movement. Record whether new fronds unfold cleanly after changes. A hanging basket should also be reachable for thorough watering and inspection; a dramatic ceiling display is a poor arrangement if routine care becomes difficult. Judge the location by the fern's sustained growth, not by the fact that it is occasionally surrounded by steam.
