The drying time for caulk varies based on the humidity, temperature, and airflow in your bathroom space. When there is high humidity, the drying time may take more than 48 hours to dry. Keeping in mind that the shower area is more likely to be humid than other parts of the bathroom.

Temperatures can also impact drying time. If the temperature in the bathroom is too high, the caulk will dry too quickly, which may cause it to crack or split when it is exposed to a shower or other sources of water. Conversely, if the temperature in the bathroom is too cold, it will take much longer for the caulk to dry this may result in extensive damage.

The airflow in the bathroom is also a factor because good air circulation can help reduce humidity levels, dissipate the heat, and quicken the drying process.
