Furniture and Furnishings - Unfinished particleboard dry sink

I have 2 dry sinks that are made of particle board with laminate tops. Each has an entire side that is unfinished, with the particle board showing, probably the side that was originally installed against a wall. I would like to do an inexpensive finishing job on these unfinished boards, but I'm a home improvement rookie, and could use some ideas. Is there some kind of surface that I can attach to these sides to finish them and make them look half-ways decent? It seems that I'm going to have to do something other than a paint job, in order to cover the particled texture.

BTW, the doors also need handles, and the previous hardware left 3 very strange holes in the front of the doors, at least one of which will need to be filled. What should I buy for filler - isn't there some kind of wood putty or ??
Thanks.

Hi - as for your particle board sides, you could get a piece of laminate that matches the top color and glue it to the particle board. For the door holes, I have recently refinished old cabinets whose original hardware spacing is no longer arund, and ended up filling 36 holes. If your doors are also particleboard, then look for wood putty in your local Home Improvement store. I was able to find a wood powder that I added water to to make a putty. You want the putty a little looser than playdough. Force it into the holes until they are filled, and use a putty knife to remove the excess cleanly. Make sure that the putty is flush with the surface. Let dry, sand with 150 grit sandpaper. You can then paint over the holes with a primer, and then finish coat. One tip I learned the hard way - buy a handle that you are going to use, and test fit it to the existing holes prior to the primer step.....<G> What I thought were three inch on center holes were 2 7/8.....

The laminate sides should be available in strips at a home center or bigger hardware store (one that sells counter tops)
You can just glue it on

Wood putty is generally too soft for the large repair of a door
(It might be OK if it's real small)
But I'd recommend wood filler
I always keep a pint of this on hand:

Elmer's Carpenter’s Interior Wood Filler
It works pretty well
