Mildew in Shower Sign In/Join 
We recently remodeled our bathroom by ourselves. For the shower, we used unglazed ceramic tiles to cover the shower pan. We're noticing that there is a strong mildew smell after about a week or so of using the shower. Even when we spray the tiles with bleach, the smell comes back within a week. We have a powerful exhaust fan in the bathroom, but it does little to prevent the mildew smell. Has anyone encountered this before? Is it the tile, or is it the grout that's causing this? Our bathroom is new so I'm puzzled why the mildew is occurring so quickly. Any suggestions would be welcome.

Could be a lot of things?
You used unglazed tiles (Truly unglazed or just a matte finish)? Are they absorbing and holding water (changing color when wet, till they dry out)? If so, that was a bad decision.

Have you used a sealant on all the grout areas between the tiles? Necessary unless you used a grout that had sealant in it, and specifically said it was unnecessary.
Drain line without proper sealing around the connections could also be an issue.

As Conrad mentioned there could be several reasons. I doubt it's the tile or grout though.

If you can describe every step of building this shower, or post progress photos, we can try to help.

Off hand I'd say it has more to do how the shower pan was constructed, but it's very unusual to get a smell after only a short time.

I assume the shower drain has the proper trap right? Well sure, of course it does.
