Suction Cups Soap Dish How Do I Install A Soap Dish In An Already Tiled Shower?

How do I install a soap dish in an already tiled shower? - suction cups soap dish

I'm installing a soap dish or corner shelf in my shower. The wall is already open. I read the reactions of others, how to remove the tiles, but I had to remove about 1 / 3 of tables 3-4 and will not pay (as most posts I say damage) on the wall.

The only soap dishes / shelves I could find was performed with a cleft lip. The lip is to be installed against the drywall so that the actual Teller / are flush with the outside world, if the tile. Is there a way to install without the tiles?

There are products that are no lips, so they must be installed on existing tables?

Thank you for reading the post. I am with a shower caddy or sucks Cuppa tiredd flat and falls at least once a week. I hope that all the help!
