Extractor fan & window ledge issue

sand_hun

https://ibb.co/34dgH0WI have a ground floor outbuilding with fully tiled bathroom which has one small window. My previous builder told me it didn't need an extractor fan as it has a window. However the room gets a LOT of condensation even after a quick shower.

Clearly I need an extractor fan. Could I get a window with a fan built in? Or get rid of the window altogether and replace with a good extractor fan. Or should I get someone to make a hole in the tiles for a fan (could be a bit messy).

Also the tiled window ledge gets soaking wet whenever the shower is used. Can anyone suggest a solution for this?

Thanks

Ideally you would move that window out of the shower.

1. In my experience, opening the window for 15 to 30 minutes after a shower will get rid of the condensation faster than any normal fan.
2. If that window is, at it appears, in one of the walls of the shower, I don't think an electric fan would last long getting regularly drenched. This would apply to either a window replacement or a fan through the glass.
3. You could get a fan fitted above the WC cistern, fairly close to the ceiling. A decent diamond core drill should get through those tiles without too much trouble, and without damage.
4. Building up the window ledge with a sloping piece of PVC would let the water run off more quickly. Alternatively fit a much abbreviated shower curtain across the window with the pole close to the ceiling. It would need to be opened with the window after a shower.

How fabulous that you found a 'builder' that doesn't understand one of the only Building Regulations that needs to be adhered to in a bathroom. :mad:

I'll have a little guess that part of the reason (aside from the lack of extraction) you have condensation is that your 'outbuilding' isn't properly insulated, either.

They don't put extractors in windows anymore, nor would you replace the window for a fan (the terrible design is a different reason).

I hope you didn't pay much for that room. . Someone with an ounce of design experience would have made that work. I'm surprised that most convenient location for the toilet appears to have been used at the detriment of common sense and there's still the most amazing amount of dodgy boxing. It's sloppy.

An electrician will easily be able to drill through the tiles for you at high level. The box will cover any rough edges. It would probably be sensible to wall-mount the cable to it under a piece of trunking, rather than cut the tiles.

One other possibility is to have a fan located elsewhere in the room -- perhaps above the door or in the ceiling -- pushing air into the room from the interior of the home, so not cold air. It would push the humid/malodourous air out through the partially open window.

What’s above the shower? You could possibly use a ducted fan with vent mounted in the ceiling, you can even get “showerlite” ones that have a SLV LED light in them. Or perhaps a fan with an automatic door (eg Icon) and go straight up through the roof if it’s a single storey building.

Fit a fan with a humidistat rather than timer and it will help keep the moisture levels down in that room.

The detailing between walls & ceiling doesn't look to hot either.. And I'm wondering where the toilet roll is in relation to the pan.
There really was no need for boxing up the side of the cistern - That could have been easily avoided by using bottom entry fill valves & overflow. The tiling in that corner also looks a little off.


As for an extractor - That really does need to be installed in the ceiling - If there is access from above, ducting & cabling could be done very discretely.

Did you pay for that work? The silicone around the cistern is horrible, the cracked tile to the bottom left is also not acceptable. There appears to be no silicone seal between the shower tray and the tiles so water will escape there and I can't believe the window!
