I want to build a home work station about 1.5-2m long ideally white/marble type of color to blend in with the furniture.

ikea linnmon is sold out - what other quality options are there? 

 

Check out " Index furniture'......Can get something like this. Its about 2000 Baht

I made a very useful table buying "hairpin" iron legs from Lazada and a solid core, smooth top wooden door from a local door manufacturer. About B2500 all in though it was finished wood and not marble toned.

The 28" legs I found were about B800/set4.  These are much more.  Also available at Thai Watsadu
