Why can't you use sanded CAULK for ALL tile joints in your shower?
 
Also, does sanded GROUT allow water to pass through it and under the tile?

All my joints are over 1/8 inch.

And one more question...I have a small gap in my shower floor that needs patching. Should I score it and use sanded GROUT?

Why can't you use sanded grout for all the seams in your shower?
Money. Time. Grout is easier to clean and maintain. Caulking needs to be replaced periodically. Grout doesn't unless something was not done right.

Also, does sanded GROUT allow water to pass through it and under the tile?
Yes. Grout is not water proof. Sealed grout is not waterproof. A shower should be 100% waterproof before the first tile goes up.

Probably. Got a pic? Keep in mind "small" issues (like loose tiles) on the floor or lower area of a shower can be symptoms of a bigger problem or that something was not done right. Keep an eye on it.

What do you mean it should be water proof before the first tile goes up? Under my tile is thin set..and then under that is the shower pan...and then under that is sand...and then under that is concrete foundation. Is this wrong? Is this waterproof?

I don't understand how it is acceptable to have water pass through your grout and then subsequently, under the tile. Can you explain?

Also, why does the sanded caulk state that it is not for areas with constant water exposure?

Thanks for your time.

If you read this link, you will see that there should be a showerpan liner in there. This ensures all of the water goes down the drain and not soak into the subfloor underneath.

I wrote this post a while back. Maybe it will help explain.

Don't know. Possibly means being wet 24/7 rather than daily shower type situation.

Are you saying sanded caulk or did you mean sanded grout?
