No.
Someone else does though!

I somehow doubt looking at those pictures, he is actually a tiler.
Honestly if that is the best mitres he can do with plastic trims

 

[Andy Allen]

Is there an alternative to trim?

Decorator chaulk, and paint down to the edge..

Got any pics of how it’s done Waluigi?

Not really. Only got this one of the job I’m on at the moment. Gives a slight idea. All I have.

That's painful to look at definitely not a tiler only advice I can give is remove the lot and start again bevelled metros look better with no trim in my opion, but can be done so much better done than that time to find different tiler maybe post on here plenty of quality tradesmen maybe some in your area.
