Many homeowners find that their bathrooms are obviously cleaned and spotless, but still filled with unpleasant odours. What’s going on here? Next, Mr Home Improvement will discuss with you the source of bathroom odour and bathroom odor fixes methods.
First, the source of bathroom odour
Before we start to solve the bathroom odour, we must first clarify the source of the odour. Floor drains, toilets, sink drains and dark bathrooms are usually the four main sources of bathroom odour. Want to completely solve these problems, renovation should pay extra attention.
Second, how to prevent bathroom odour when renovating
Floor drain odour
Floor drain is not only the bathroom drain, but also an important barrier to block the sewer odour. If the floor drain sealing performance is not good, the sewer bacteria, mosquitoes and odours will take advantage of the situation.
Therefore, when choosing a floor drain must pay attention to its anti-odour function, it is best to choose to have anti-odour, anti-return, anti-bacteria, anti-clogging four anti-drainage. Common types of floor drains are deep water sealing floor drains, shallow water sealing floor drains and T-type floor drains.
- Deep water seal floor drain: the internal U-shaped water seal design, can effectively isolate the odour, suitable for areas with high water consumption, such as the shower area.
- Shallow water seal floor drain: also with U-shaped water seal area, but the depth is shallower, suitable for areas with less drainage.
- T-type floor drain: the inner core is equipped with a spring or magnet switch, which automatically opens when there is water and closes when there is no water, suitable for dry areas with small drainage. In order to extend the service life of the floor drain, it is recommended to choose all-copper core, which is easy to be replaced later.
Toilet odour
If the floor drain is not the source of odour, you need to focus on the toilet.
- Water seal height: the height of the water seal of the toilet determines its effectiveness in blocking odours. If the water seal height is lower than the national standard (<50cm), it is easy to produce odour. It is recommended to choose a toilet with a water seal height of 55-60cm.
- Flange ring: If the odour emanates from the bottom of the toilet, it may be due to poor sealing of the flange ring. Flange ring quality or aging easily lead to odour. At this time you need to ask a professional master to replace the new flange ring, and seal the toilet with glass glue.
- Glaze material: glaze poor toilet easy to adhere to the dirt, long-term use will be discoloured and produce odour. It is recommended to choose microcrystalline anti-fouling glaze and other high-quality glaze materials, both to maintain the luster and easy to clean.
- Drainage: Toilet drainage methods are mainly direct-flush and siphon type two. Direct-flush toilet drainage smooth but easy to return to the smell; siphon toilet anti-odour effect is good but easy to clog. In order to get a better anti-odour effect, it is recommended to choose the siphon toilet, and avoid throwing paper towels into the toilet.
- Ordinary/Smart toilet: Smart toilet is more with sterilisation function and better deodorising effect. If the budget allows, you can choose smart toilet to enhance the bathroom environment.
Basin sewer odour
The basin drain must be sealed tightly, otherwise the odour will overflow. In addition, the water pipe should be set up to store water elbow to maximise the prevention of odour overflow. Currently, S-type and P-type elbows are more commonly used, with S-type elbows having a better sealing effect and P-type elbows being suitable for back-wall drainage.
If the budget is sufficient, you can choose the upgraded version of the S-type water storage bend to achieve multiple protection. However, it should be noted that it is not recommended to install double storage bend, so as not to affect the speed of water and cause blockage.
Dark bathroom airtight
Some homeowners due to the restrictions of the type of bathroom without windows, ventilation and lighting are poor and humid and easy to produce odours. Therefore, the renovation needs to work on ventilation and lighting. Mr Home Furnishing suggests that from the increase in ventilation and lighting to enhance the two aspects of the start, which increases the ventilation is an effective way to reduce the odour.
- Check valve exhaust fan: most families will choose to install exhaust fans in the bathroom, of which the ceiling exhaust fan is more popular. Installation should pay attention to the installation of non-return valve to avoid the neighbour’s bathroom odour backflow.
- Fresh air system: If the exhaust fan does not have enough airflow, a fresh air system can be installed to continuously provide fresh air to the space. The bathroom usually has a separate ceiling, so it is easy to replace the filter or maintenance later.
Third, how to remedy bathroom odour after renovation
Attention to the above points during renovation can effectively reduce or eliminate bathroom odour. For renovated houses, Mr Home Improvement also provides the following deodorisation methods:
- Intelligent toilet cover: If you have not installed an intelligent toilet, you can install an intelligent toilet cover on an ordinary toilet to achieve deodorisation, and it is easy to install.
- Clean the dead space: The dead space under the bathroom cabinet and the gap at the back of the toilet should be cleaned regularly to prevent odour from growing.
- Placing plants / aromatherapy / air freshener: in the bathroom to put hanging orchids, ivy and other green plants can purify the air; or placed in essential oils, air freshener to improve the bathroom environment.
Bathroom odour is not terrible, as long as we carefully find the source of the odour and take appropriate measures, we can easily achieve bathroom odor fixes.
