Kitchen flooring help

Katb1989

I need some help and advice for flooring in our kitchen which we are renovating.

We recently bought a house that had an extension built onto the kitchen so there is sunroom on the back so is one big room. However, they left a half wall (where the window used to sit) and a single backdoor sized gap between the other wall for the entry to the sunroom.

The floor between the kitchen leading to the sunroom is sloped from where there used to be a step. At the moment, the flooring is tiled throughout including the slope. Whoever put in the tiles has definitely used extra cement to create the slope between the two areas.

So now after having our new kitchen in, we're looking at replacing the flooring. We removed the half wall and the builders concreted up the floor, creating additional slope that is mostly level with the tiles. Only this potential bodge job is causing us problems in flooring selection. I want vinyl as tiles are cold and as the room is large, to cut down costs.

But because of this slope I keep being told the vinyl will wear away quickly as it's not smooth. Screeding is an option but I don't think it'll level it out enough.

Laminate is apparently a no go on slopes. We don't want part carpet/part laminate and tiles are cold. Underfloor heating is also expensive and the tiles are cemented anyway!

Levelling is an option, but there needs to be access to the main water waste pipe that was put in the middle of the floor (previously hidden by the wall which we removed). I don't know much about levelling though or how expensive or what we need to do or who we ask.

So I just need some advice on the best method if possible. Or other options. Just something that'll stop my brain from hurting please? I'm not sure the full measurementa of the slope because tiles are still there.
