Yes would be solid ones I think would look poor though too 75mm extensions either side
Edit
It would be 80mm too short for the current pipe centres so two 40mm extensions or an 80. Still I think would look poor
They look like this. They do them in 1000 and 1200. I need an 1100 as this is what is in and I can't alter pipes can't get under the floor is tiled no access
Did you send it off to a factory to get done? Does it look professional like the eastbrook black ones you can get. Can't use the eastbrook ones as I need a size they don't do.
