How to create short kitchen benchtop for one sink cabinet?

[frumbert]

I would like a single 900 x 600 laminate benchtop to for on a standalone 900 wide base unit that is used for a circular 400mm sink. I'd prefer a laminate surface but could do a timber surface if I knew how to seal it properly for kitchen use (my past attempts at using timber benchtops have all been a black soggy disaster). All the benchtops seem to be sold at 2400 length, and I don't have a use for the excess, and if cut how would I properly seal the ends? I don't know how laminate benchtop ends are sealed either.

To get a benchtop at that exact size with finished ends @frumbert, you’d be looking at either cutting down a standard length or placing a special order for a custom-made benchtop. Most laminate benchtops are supplied in 2400 mm lengths, so to achieve 900 × 600 you would need to cut one down. When laminate benchtops are cut, the exposed ends are normally sealed with an iron-on edging strip, which is bonded on with adhesive and then trimmed flush. If you don’t seal after cutting, moisture can get into the particleboard core and cause swelling, so finishing the ends properly is essential.

If you want something made to size with fully finished ends straight from the factory, a custom benchtop is the cleanest solution. These aren’t as expensive as many people expect, and the Special Orders team in store can walk you through available colours, profiles, and lead times from the manufacturers.

With timber benchtops, the key to avoiding the soggy, black edges you’ve experienced before is full encapsulation. Every surface must be sealed, not just the top. That includes the underside, the front and back edges, both cut ends, and especially the inside of the sink cut-out. A durable varnish needs to be applied in multiple coats. If even one cut edge or the sink opening is left unsealed, water will find its way in and start breaking the timber down.

Given the size you’re after and the fact that it’s for a sink cabinet, a custom laminate benchtop is probably the most practical and low-maintenance option. I’d suggest heading into store and having a chat with Special Orders so they can price up a made-to-measure option.

Please let me know if you have any questions.
