Inspection cover replacement

[Candyman85]

Hi all

Looking for advice on how to change this inspection chamber setup for a recessed one so it blends in with my path and is square to the path

As you can see from the pictures I laid the path thinking I could live with the ugly concrete chamber that’s squint but the more I look at it the more it annoys me

All help is greatly appreciated

You will not get just a replacement cover. Any new cover will come with it's own frame. Get the type that you can infill with slabs close to the old size. So you need to remove old cover and frame carefully without dropping stuff into the drain - best to put a cloth down if it's you own drain that you can keep dry. Then set the new cover on the old brickwork with mortar to get the right height. Then you fill in the new cover with matching slabs.
PS I've only seen a builder do it.
