How can I make the space between the floortiles of a showerfloor waterproof.. ?

Question

I made a showerfloor with the same tiles as the bathroomfloor, but every time I shower, there 's humidity that stays for days between the tiles.. although the floor is constructed downwards... even the tile edges stay humid...

Answer 1

Grout the joints and seal it.

Answer 2

Use waterproof grout to fill in the joints.

You can get this from any building material dealer. It comes in small to large sacks, that you mix with water.

By the way, It is not a bad idea to mob the floor after showering.   :-)

Have a good day.
