What Is the Right Temperature and Air Humidity in a Bathroom?

The right temperature and ventilation in the bathroom will keep the structures dry and bathroom dries fast after usege.

Optimal temperature in the bathroom ensures pleasant usage, but plays an even more important role for the drying of bathroom structures and fittings. Suitable temperature in a bathroom is usually around 23-24 °C.

Bathroom floor heating and recommended temperature

Underfloor heating is sufficient in the bathroom when the floor feels neutral against your foot. The floor is not meant to feel warm or hot, but the surface temperature should be between 23° C and 24° C.

Underfloor heating is often one of the biggest contributors to high electricity bills. It is worth keeping the bathroom door shut to save money, so that the heat does not escape to the rest of the home.

Bathroom air humidity

Relative humidity can temporarily rise to 100% in the bathroom, so ventilation needs to work well to cope with such humidity. If humidity stays up for a longer period of time, moisture can condense in cold corners of the room and cause unfortunate moisture damage. Suitable humidity in the bathroom should be around 30% to 60%. You will know that ventilation in your bathroom is insufficient if moisture condenses on bathroom surfaces for several minutes.

Bathroom air humidity and temperature measurement

A proper device for measuring humidity in the bathroom is RuuviTag or RuuviTag Pro (3in1). Both of these sensors measure humidity and temperature. Install the sensor at the height of your head. We suggest that the device is installed far enough from the shower, as the breathable membrane may absorb water if the droplets remain on its surface for too long.

Once the sensor is installed, you can monitor real time temperature and humidity levels from the Ruuvi Station app. You can also observe the history graphs to see whether it is excessively humid in your bathroom for longer periods of time. You can also place Ruuvitag to bathroom floor and you can easily monitor floor heating cycles and adjust thermostat if necessary. If necessary, you can set alarms from the application that will alert you about undesirable conditions.
