Hello,
I hope to find some advice here. I am currently renovating the bathroom in my house, built in 1928.
Since not everything in a house of this age is perfectly level, a problem has come up.
At the transition from the bathroom (tiles) to the door threshold (painted wood), a gap has appeared (see pictures). The gap is about 5mm (0.2 inches) wide on one side and 15mm (0.6 inches) wide on the other side, with a total depth of around 15mm (0.6 inches).
Now my question: what is the best way to fill this gap so that a) it lasts a long time and b) looks neat?
My ideas are as follows:
Cut the rounded edge of the door threshold with a multi-tool to create a straight edge. Then fill the gap with epoxy resin? epoxy mortar? Afterwards, sand down and repaint the threshold.
Another idea was, after straightening the threshold, to glue a custom wooden strip to it. The question here is whether this can be done precisely enough and will hold over time.
The tiler suggested silicone (I think the gap is too wide for this) or filling it with colored cement mortar.
Perhaps there are experts here or someone who has already solved a similar problem, or anyone with a good idea to help me.
Thank you very much for reading and in advance for any replies.
Best regards

Hello ypg,
thank you for the quick response.
By "remove wooden threshold," do you mean lowering it enough to reach the height of the tiles or removing it completely? To be honest, I am a bit hesitant about working on the threshold, as I have concerns. I am worried that the stability of the door/frame underneath might be compromised. I would prefer another solution.

Hello questioner.
If the wooden threshold is to remain, the only real solution is to use a transition profile.
You can find a particularly flat profile, for example, under
Transition Profile Den Helder / transition strip, 38 mm (1.5 inches).
Clean and degrease the substrate (tiles) with alcohol and fix the profile on one side to the surface of the tiles either by firmly gluing it (owner-occupied property) or securing it with a strong dry adhesive (rental property).
Good luck:

Many thanks for your comments.
The threshold will stay, as I’m concerned that changing it might create a new construction issue.
I will now fill the gap with spray cork (possibly paint over it) and see how it looks. If that’s not acceptable, I will install a flat transition strip (thanks KlaRa).
