Kitchen Showrooms mostly have the same kitchens...where is the source?

I have visited a number of kitchen showrooms over the past few weeks, viewed a number online and looked at a few brochures. Nearly all of these well known outlets are stocking the same kitchens, they just call them by different names. They have lovely showrooms and the colours they choose are different depending on where you go.
When they display their kitchens online and you turn up at their showroom the showroom does not match the online pictures. In other words these are stock pictures that they are using.
The one thing I have noticed is that they are all basically the same standard design, the doors are standard, everything is the same...just displayed differently.
Does anyone know the source for these outlets. The actual place where the doors are made and is it possible for an individual to just purchase these from the manufacturer?

most kitchen companies buy in the doors and produce their own carcass. The doors come from a variety of sources, mainly uk companies. search trade kitchen door manufacturers in google and you will get a list. Some will sell direct but a lot wont.

You can buy doors from softline in ballyfermot, You can buy direct from them
Unit 21, Cherry Orchard Industrial Estate, Ballyfermot Rd, Dublin 10

You can by kitchen cupboard doors seperately from either In House or Tierney Kitchens.

Go to their trade counters and ask to buy the doors seperately.

In House is also known as "The Panelling Centre".
