Tips for solving door trim at dishwasher

[Dr Benz]

I have had the same problem as the floors do not extend far enough underneath.

I bought flat oak thresholds that were deeper than the frame. I sawed them on site and simply laid them on top of the floors. It's a bit tricky but can be done with a jigsaw.

So narrow frame and wide threshold plank.

I would have done what someone mentioned earlier. Buy a piece of oak and place it between the threshold and the floor, it needs to be wide enough to cover the old kitchen floor about 15mm. Saw out or mill a groove on the underside so the oak piece rests on the subfloor, against the threshold and over the kitchen floor. Adjust the groove so that there is a gap in the groove between the kitchen floor and the oak piece so the kitchen floor can move (4-5mm)

But on this wide oak threshold, I assume the rebated threshold should lie. Between the frame sides. Is that how you think? Threshold on threshold?

I bought flat oak thresholds that were deeper than the frame. I cut them to fit on site and simply laid them on top of the floors. It's a bit tricky but doable with a jigsaw.

So narrow frame and wide threshold board.

So you bought one or more oak thresholds and cut them so you could place them between the frame sides while also covering the gap between the floor and the subfloor?

No, lay the oak piece along the oak threshold and make it wide enough to go over the kitchen floor about 15mm. Make a groove along the underside so the kitchen floor goes free.

So you bought one/several oak thresholds and cut them so they could be placed between the frame sides while simultaneously covering the gap between the floor and subfloor?

Exactly a threshold box that was cut to the shape of the frame and how it was placed. It was wide enough to cover the floors on both sides of the frame.

I replaced the door frame with a 92mm one instead. It feels more appropriate, but it will really be a tight fit. I haven't unpacked the new frame and double-checked. However, I'm considering whether it's better to remove the surrounding molding and reframe. Ideally, I want to avoid as much work as possible and just install an interior door nicely.

I also bought a rebated threshold + a straight threshold to place under the rebated one to close the gap and provide height.

How thick is the wall? The frame is about 90-95mm deep. You cannot align it with the kitchen wall; it needs to align with whatever is behind the door. The thinnest trim you can buy is 8mm but you can of course split a molding with a table saw to about 3mm for it to fit.

105mm is the frame's thickness on the dishwasher side.
