How can I seamlessly end the baseboard into the plinth blocks without cutting too much off?

So, we just finished redoing the floors in our place and now I’m thinking about redoing the door casings and baseboard. I have this weird fixation on plinth blocks and really want to incorporate them into the new casing/baseboard, but I’m running into a bit of a dilemma. About half of our doors already have this setup. Any suggestions on the best way to end the baseboard into the plinth? Should I just butt them together? (Just FYI, the plinth does reach the wall – I accidentally cut too much off the one in the photo.)
If all of them are the same, I might just sneak a peek at your reveal.
I have no clue what that means lol move the plinth block closer to the door opening?
Don’t place it right next to the door. However, only if they are all exactly the same size. Another option is to create your own blocks and customize them all to extend all the way to the wall.
I had to trim some off the one in the picture (and I cut too much so I’ll use a different one for the actual installation haha) but they’re large enough to reach the wall. I’m trying to decide the best way to finish it…just butt the baseboard against it or something else?
Yes, just butt them together.
I made some changes to the post… I noticed it wasn’t very clear.
If I were doing it, I’d use biscuit joint for the plinth, casing, and architrave header. I tend to go above and beyond. However, butt joint should work well in this case.
Oh hey, , thanks a lot!
How wide is the casing? You could carve out space on the wall side of the baseboard, so it sits flush against the wall.
Alternatively, you could cut two blocks at an angle to trim the entire corner.
The casing is going to be 3 inches. I wish the picture showed it better. The plinths are large enough to reach all the way to the wall (actually too large, so I had to trim it and ended up taking off too much). Should I just place the baseboard against the plinth? Not sure if there’s a better approach.
I made some changes to the post because it was kind of confusing before
In my opinion, it’s not very aesthetically pleasing to have a noticeable height difference at the corner. I recommend cutting two plinth blocks at an angle to seamlessly blend in the corner, and then adjust the base accordingly.

Hmmm, is quite intriguing
Seems quite wrong to me
To be honest, I’m not a fan of the sudden change in height at the corner. I would suggest cutting two plinth blocks at an angle to fit neatly in the corner, then align the base accordingly.
Sure thing, go ahead and turn the corner like you normally do and adjust the plinth blocks if necessary. It will give a nicer and more seamless appearance.
I had a similar problem when we redid our floors, which made all the door casings 3/8″ too short. I ended up trimming 6″ off the bottom of all the casings and creating my own plinth blocks using 5/4 wood pieces. Instead of mitering the top edge, I added 3/8″ decorative shoe molding. In your situation, you could consider adding shoe molding or cove molding on top of the baseboard for a personalized touch that prevents dust from collecting on a flat surface
Yes
Just like you already have it. Or cut it at a 45-degree angle and then add a 45-degree return piece to the wall
Thanks everyone. Managed to get the casing up today. Planning to paint the baseboard and put it in place tomorrow.
Sure, I’m into that.
If there’s still time for a vote, I’d say do it just like you have in your OP picture.
