If its a choice between Wren and any other kitchen provider in the universe go with the other! I had nothing but trouble dealing with Wren. They were much more expensive, expected me to organise the individual contractors (tiler, plumber), the quotes from their nominated contractors came in AFTER I had the work completed by a Howdens specialist and had to chase them for months to get my 'fully refundable' deposit back. The Howdens contractor did everything from the design (picking up major design flaw in the Wren design) to the aftercare. I got solid wood doors and solid wood bench tops for less than what Wren quoted for cheaper options. He even came back and did some extra decorating work to finish the job off nicely. Dealing with Wren was a total nightmare.

If you go for a quartz or other solid surface, then any fabricator should be able to do a table for you. You need to face the back with something, we used mdf when we did it, and attach legs of your choice. In laminate you would need to buy a breakfast bar type top and use edging strips on the ends, so would have width limitations.

If space is your priority, perhaps the second toilet would be better? What brand is it, btw? I will eventually be redoing a bathroom (had planned to do it this year, but gas price rises have made me decide to install a wood burner instead). Really like the shape of this second toilet and it looks like it would be so easy to clean.

Hi, sounds fabulous! I believe the best way to tackle this is to use a pivot hinge on the door. See pic below, but I would place the pivot fairly close to one side  so you still get a decent sized opening. Using a hinge like this means you will not need architraves inside that room and the plaster can go right up to the opening, allowing a smooth base for the mural.
