Transition door threshold (wood) to tiles

Hello,

I hope I can find some advice here. I am currently having the bathroom renovated in my house, built in 1928.

Since not everything is perfectly even in such a house, a problem has now arisen.

At the transition from the bathroom (tiles) to the door threshold (painted wood), a gap appears (see pictures).
The gap is approximately 5mm wide on one side and 15mm wide on the other side, and about 15mm deep in total.

Now my question is: How can I best fill this gap so that a) it lasts a long time and b) looks decent?

My ideas are as follows:

Cut the rounded edge of the door threshold with a multi-tool to create a straight edge. Fill the gap with epoxy resin?, epoxy mortar?, then sand and repaint the threshold.

Another idea was, after cutting the threshold straight, to glue a fitting wooden strip to the threshold. The question is whether this can be done precisely enough and whether it will hold.

The tile setter suggested silicone (I think the gap is too wide for that) or filling the gap with colored concrete mortar.

Maybe there are professionals or someone who has already solved such a problem or someone with a good idea to help me here.

Thank you very much for reading and for the answers in advance.

Regards

Remove the wooden threshold, then tile the area and install a sliding door to the hallway.

Hello ypg,

thank you for the quick response.

By "remove wooden threshold" you probably mean lowering it so that it reaches the height of the tiles or removing it completely? Honestly, I have reservations about working on the threshold, as I am apprehensive about it. I fear that the stability of the door/frame beneath might suffer. I would prefer another solution.

Hello questioner. If the wooden threshold is to remain, the only way to achieve the goal is actually by using a transition profile. A particularly flat profile can be found, for example, under Übergangsprofil Den Helder / Übergangsschiene, 38 mm, Clean/degreet the substrate (tiles) with alcohol and either bond the profile firmly on one side on the surface of the tiles (property) or fix it with a good dry adhesive (rental object). Good luck: KlaRa

Many thanks for your comments.

The threshold should stay, as I’m afraid I’d open a new can of worms otherwise.

I will now close the gap with spray cork (possibly paint over it) and see how it looks. If that’s not okay, a flat transition strip will be put on (thanks KlaRa).

Best regards, kunde
