To reduce the risk of mould and mildew forming in your bathroom you need to ensure that it’s well ventilated. Whilst you can purchase special paints that are designed to cope with the high humidity of a bathroom and caulks that are resistant to mold and mildew; installing bathroom venting will also help to prevent your bathroom from becoming full of steam when you’re in it.
Bathroom Venting Options
If your bathroom has an ‘outside’ wall fitting a window with opening casements is the best option. However, even if you have an opening bathroom window adding an alternative and extra vent can be very useful. After all, depending on the climate where you live it might not always be convenient, or even possible, to open a window.
Whereas a venting system could keep the bathroom ‘aired’, without the need to keep a window open. Vents can be fitted with or without fans and the fans can be electrically powered or not. Fitting a powered bathroom fan ventilating system will require you to make a connection into the electric power lines in your home. If you don’t feel confident about working on the electrical supply, the following are alternatives to installing powered bathroom vents.
Installing a Louvered Ventilator
If you visit a DIY store you’ll find frames with thin louvers on them that can be fitted into a bathroom wall or window. The louvers can be opened by either pulling a chord or, if the louvers are slatted, simply by pushing a connecting bar.
To fit one into a bathroom wall, using powered drill with a core drill bit; create an opening in the wall that the louvered frame will fit over, but is large enough to maximize the ventilating capacity of the vent.
If you haven’t got a core drill bit you can alternatively chop through the masonry with a hammer and bolster chisel. Of course, if you have a timber finished building you can saw a suitably sized hole.
Being of a very light construction, if you have a circular vent you can fit it into the glass of the window with a circular glass cutter. Find the centre point of the window and mark it. Add 1/16 inch to the diameter of the hole you need to cut, set the arm of the cutter to half of that measurement.
Attach the sucker over the centrally marked point and score the glass evenly around the whole circumference in one go. A tip next is to not try and remove the piece as one piece; instead score across the diagonals of the circle with the cutter.
Carefully, supporting the other side of the glass with a hammer head, gently tap out the pieces of glass with the back of the glass cutter. The vent can then be installed over the hole, with the flanges covering any rough edges.
Airbricks and Bathroom Ventilation
An essential feature for ventilating underneath suspended ground floors is the use of ventilation bricks. If your bathroom is on the ground floor above a suspended floor you must keep any airbricks in good maintenance. If broken or damaged you must replace them or you could end up with an infestation of unwanted pests.
However, if the airbricks become blocked the floor of your bathroom could rapidly deteriorate. Replacing airbricks is an easy job for the DIY home enthusiast to tackle. If the airbricks keep repeatedly getting blocked up, fit a louvered grill over them to help reduce the risk of them getting re-blocked.
