I am currently installing a powder room in my basement. It will not have a window in it, so I need to install an exhaust vent. The nearest window is ~5' away, and it is a pre-made glass block window with a 8"x16" vent in it.

Is there any easy way to replace the existing vent with the vent for the exhaust fan? I know they make one that fits in the space of an 8"x8" glass block, but what do I do with the other space?

Can I remove the existing vent without damaging the rest of the window?

Will I be able to do this swap with the window in place?

TIA

can you duct the exhaust fan [e.f]to the window with 4 inch duct? then take out the exist vent. and reglass block it. leaving a 4 inch hole for the e.f. finish off the out side, with a dryer vent termination. you never said if the vent hole was being used already?

Ok, let me clarify.

Here is the window I have:

I somehow need to run the ducting for the exhaust fan vent to that existing window. The only thing I can think of is using somehting like this dryer vent on one side, and putting another glass block for the other side:

I'm just wondering how difficult it is going to be to remove the existing vent and installing the 1 block and dryer vent.

Or I'm willing to hear any better ideas.

you mentioned the window was 8 x 16, but looking at the picture it looks like the bottom row of blocks is smaller than the top row. i would suggest you make sure the blocks in your window really are 4 x 4 before you do anything.

i guess the worst case scenario would involve you simply removing all 8 blocks and just putting in 7 new ones and 1 vented one

The window isn't 8x16, the vent is. It takes the place of (2) 8x8 glass blocks. I guess what I am looking for is any tips on the install, since I have never messed with glass block windows before.

glass block is installed the same as concrete blocks, use morter,or see what new and expensive adhesives are at ho depot. as far as taking the vent apart use a sawsall, with a metal blade,and a grinder with stone wheel go slow take your time you can doit
