My son was in the tub the other night and when he went to climb out he pulled the soap dish clean out.I cleaned off the soap dish and the opening in the tile (1 & 1/2 cut) but now I dont know what to use to put it back in.
Would grout work or would morter be a better idea?.
Thanks.

 

Get a small container of premixed adhesive. Grout won't hold, it's not meant to be an adhesive. Tape it in place while it dries (and you might install a handhold while you're at it).

 

Go to home depot and get a small container of thin set mortar. Mix it up, apply and tape your soapdish in place like tow-guy said.
The premixed mastics don't recommend using that to hang fixtures. Liquid nails has an adhesive they say works but I don't have any experience with it.

 

Wasn't aware the premixed stuff had a lower holding power (haven't hung any soap dishes lately).

 

Will the thin set work itself behind the wall too or will it just stick to the tile?I dont feel like replacing it again(no time,Im working on the rec room).Thanx for your help gang

 

I'm not sure what you mean about the thinset working itself behind the wall. ??
You should have either sheet rock (gypsum) or hard backer (looks like concrete) under where the soap dish was. If you have a deep hole, we're talking a whole different set of problems.
If you have a suface there, just mix up the thin set mortar and "butter" the entire back of the soap dish where it will contact the wall. After you set it in place (push hard), gently wipe off any mortar that squeezes out, with a damp rag. Then tape the dish in place with either duct tape or a good masking tape. Don't touch anything for at least 24 hours. (If you leave a little thin set on a glazed tile, it should scrape off fairly easily when dry, but try to wipe it off while it's wet.)
I would recommend using caulk instead of grout to finsh off the job. A good latex grout should last if it is allowed to dry a day or two before it is exposed to water.
