You're right, it will happen as seen in some place of worshiping.
Alternatively you may consider industrial type of smoke extractor. Smoke Extractor c/w ducting

Hi, I’m looking for ventilation fan suggestion for my bathroom at ground floor
Initially the bathroom is quite big with shower head too, but since we seldom use it, we decided to make the toilet smaller and spare some space for washing machine area

The initial layout:



Proposed layout:



Recent progress:




As you can see, with the wall coming up, there will be no ventilation in the toilet, and also it’s going to be very dark
Thus I am planning to install ventilation fan on the wall
Any brand or particular fan size to suggest? Saw the KDK brand fan cost around RM100+.. is it good?

And is it OK to direct the air to that area? Or better to have ducting directed outside?

Thanks in advance

I will demolish the dividing wall ... instead

Create a smaller partition wall for the WM using glass blocks.

Aggree and no need for full height glass, leave space at the top for air to circulate

Can also change one strip of ventilation blocks so that the toilet is always ventilated. This will prevent the tupperware stink bomb problem if its not vented.

Something like this https://www.ewarehouse.my/pbm-ventilation-block

Can anyone please share contact to install ventilation for bathroom?

Intend to replace my current lighting with ventilation feature on my lower ground toilet onto the plaster ceiling as i intend to close off the existing window (which leads to the kitchen). However need to also install a new duct for this

Get KDK

Have anyone tried AIREGARD SNS-300? Is it good?
this model has CFM 300 which is far cheaper than the KDK model having similar CFM but not sure if is good or any problems with it.
anyone?

Anyone can reckon a good brand for this ventilation? Ventilation without ducting as there's no way to hack a hole for apartment. Tq. =)

Ventilation w/o vent is called tupperware.
Most ppl mount that 6in propeller fan on the window. Or you can install the typical 10in exhaust fan and board up the rest of the window with clear plastic, this work much better for drying the bathrooms.

Ok thanks.. probably will just put at plaster ceiling to suck up..

ceo684 already warn you about "tupperware". If you are going to vent into an enclosed plaster ceiling, you might as well not vent at all. Mold and mildew is going to form in the plaster ceiling cavity, unseen and undetected, until it is a big problem.

You are better off placing a stand fan at the door of the bathroom and blowing in after you shower.

Hi sifu…

What is the estimated price to install window mounted exhaust fan? Originally i plan to install 6in exhaust fan but my contractor suggested to me to opt for ceiling exhaust fan with light instead, his reasoning is window mounted type is much expensive (need to disassemble the window and cut the window glass in the factory) and it can be auto on together with the light.

Since this thread is about exhaust fan, another question is about exhaust fan in the kitchen. Do i still need to install exhaust fan if i have hood and large window area. I usually do heavy cooking - deep frying, all kind of tumis etc..

Could be very cheap if just mounting onto a piece of plywood or metal frame made from L angle beams

For kitchen leh basically it is a question of form vs function.
1. Cheapest solution is board up the window pane (prevent blowback/blowby) and install a 12" big exhaust fan preferably made by a brand with three letters in the brand name and starts with a K with over 700 cfm. Cheapest no-nonsense solution.

2. More elegant solution install a hood (vented type) with high suction rate. This will cost a bit more.

Noted. I will inform my contractor ok the mounting onto plywood. But i’m afraid due to the strata building i cant do this option.

Yup i already bought a good hood from zean 😁. So exhaust fan no need already ya 😮‍💨

Thanks so much for your suggestion and advice. Your comments in forum really helped me a lot in my reno planning.
