there are. The doors are mostly made from standard board in standard sizes, but some will cut and edge to order from a wide variety of colours and finishes. End decor panels and infills are no problem. These laminated and other boards are widely used in shopfitting and bars as well as boxy furniture and kitchens. If you look at your wardrobes I think you will find that, like kitchen units, they are just boxes made of rectangular panels fixed together.
however a couple of companies I have used in the past closed for lockdown and do not seem to have reopened.
If you search for a "laminates" company in your area you will probably find a stockholder and supplier to the building and shopfitting trade. They may not want to supply retail but will know local companies that do bathrooms, kitchens and bedrooms. If not, sit in their truck park and wait for vans to turn up. It's usually a warehouse on an industrial estate, well away from glossy high streets. you can get samples of boards from companies like Egger (probably free) who may also tell you a local stockholder. Retailers may charge a pound or so per sample. Some installers cater for the glossy end of the market and price accordingly. A supply company will use computer-controlled machinery for cutting, edging and drilling, and I find the precision is much better than an on-site carpenter can do.
Prior to covid I was able to order shelves, doors, panels and kitchen units on 24 hour delivery, drilled for hinges as required, in standard and special sizes.
I try to avoid Vinyl Wrap because I do not consider it durable, but you can get paint-sprayed shaped MDF, and flat laminate which is most durable (like a kitchen worktop) if you happen to like it.
