ᐅ Seal the gap between the shower base and the wall

Hello everyone,

I have a problem:

As you can see in the picture, one tile is too short, leaving a gap.
Now my plumber says that the too-short tile must be replaced with a longer one. The problem is, it’s already a full tile. This means all the floor tiles in the entire room would have to be removed and reinstalled to keep the grout lines consistent.

Long story short: Is there a way to create a gap between the wall and the shower tray to cover the gap shown in the picture? My plumber says he wouldn’t be able to seal it properly, or guarantee a waterproof finish.

It would be great if you have a reliable solution for this.

Thanks!

I agree with the plumber on this. You should also ask the tiler about the issue.

Mistake by the tiler

It should be sealed with MS polymer. Completely waterproof and airtight, curing underwater, commonly used for hull penetrations on ships to seal them (such as echo sounders, vent outlets, etc.).

Practically no shrinkage. Practically never fully hardening, especially not on the inside, extremely adhesive without the need for a primer.

Here is a joint between a wall and a staircase that we sealed to close the gap. Saba Tack white was used.

Sealing tape apparently missing between the shower tray and the wall as well......

No, definitely don’t let them cut corners. It’s not your problem that the tiler did the work incorrectly. You end up frustrated every time! He has to measure and adjust properly so that this doesn’t happen! He just has to start over if necessary. After all, he’s the professional who gets paid for this. It’s his trade, and he must know how to do it properly.
