The absence of a window in the bathroom means there's no source of fresh air or natural ventilation. This can result in unpleasant odours lingering in the space, which can be off-putting for both residents and guests.
Use white vinegar. Buy a big jug or two. It works very well and bonus: it's cheap. It has a mild odor that fades quickly, but it does not give off fumes like bleach or other chemical cleaners. I can keep going with cleaning in a bathroom with no window for ventilation if I use vinegar.
If you don't have any windows in your bathroom, consider investing in a ventilator fan or dehumidifier. This will have a similar effect to an open window, getting rid of excess humidity in the air after your shower.
Does a bathroom need a window? The short answer is no, a bathroom does not need a window, but it does require ventilation. Every state has their own requirements and codes, but a proper ventilation system is a must.
Does a Bathroom need a Window. Whether you're building a new home or planning a bathroom renovation, one question you might encounter is, “Does a bathroom need a window?” The short answer is yes. It's absolutely crucial that your bathroom has some type of ventilation to remove unwanted moisture.
Nearly every home will experience mold & mildew in the shower at some point. Thankfully, mold growth on the bathroom shower tiles does not typically indicate a major health or structural problem.
Poor Ventilation
Problems such as shower leaks or toilet problems can cause odors in your bathroom. Most of the time, these smells are due to poor ventilation in bathrooms and showers, but some homeowners will try to improve their ventilation systems by drilling holes into their plumbing devices.
For windowless bathrooms, adding lighting (strategically, of course!) wherever you can will help revive the space. By adding a great lighting scheme in your shower, for instance, as Georgina Cave did in her London house, the room feels instantly fresher and the space more breathable.
A sewer gas smell in the bathroom can be caused by:
broken seal around the toilet in the wax ring or the caulk. A burst pipe. tree's roots have grown into or have caused damage to your sewer pipes. the sewer or main drain has bellied, collapsed, deformed, or deteriorated.
Skylights do more than just brighten your bathroom with natural light. When skylights are positioned on your roof, they keep your bathroom fresh by expelling hot air and steam while maintaining privacy.
Using Baking Soda
Sprinkle baking soda on heavy furniture, like mattresses, sofas, chairs, and carpets. Let the powder sit for at least an hour. You can also spray baking soda dissolved in water on curtains, clothes, bedding, and covers. This is the easiest way to deodorize them.
The more time that your bonus bathroom goes unused, the more likely that it will develop that bad smell. If that P-trap empties or has dried out, then you can expect that smell to seep through the room, and maybe even the rest of your house.
Can you do that? No, you can't. According to Section R310 of the International Building Code (and most other building codes), every bedroom needs an operable window that can act as a second means of egress during an emergency—so landlords can't count windowless rooms as bedrooms.
An exhaust fan can genuinely make all the difference to a bathroom without a window. These operate by pulling in all the warm air and excess moisture build-up.
Limited Space: In smaller bathrooms, adding windows can reduce available wall space for mirrors, storage, or other functional elements. Potential Water Damage: Windows in shower areas or near tubs need to be properly sealed to prevent moisture from damaging the window frame or surrounding walls.
An extractor fan can keep windowless bathrooms from holding too much moisture, and can keep your bathroom fresh while avoiding nasty bathroom odours.
Removal of Moisture Every time a person takes a hot shower or bath, the bathroom's exhaust fan should be turned on. This fan will remove any moisture that's in the air by sucking it into a duct that will redirect it to a vent leading outside.
