Hi, I had a Spotted Gum Timber Floor ( 10mm Real Solid Timber Single Planks ) in a penthouse apartment for 8 years . It was pre-coated in high gloss clear from the factory . When it was laid it was necessary to have a noise reduction 3mm foam under layer ( apartments underneath building noise requirement) . This method of installation actually made the floor very quiet and it also made it a little softer to walk over . When it got any scuff marks, they just easily wiped off with a damp cloth. When I sold the penthouse, the floor was in exactly the same condition as the day it was first laid - first class. It was only ever cleaned with a steam cleaner , no chemicals whatsoever . I would certainly recommend the pre-coated polyurethane gloss finish on the real timber planks to anyone, it was great ! You can just see a glimpse of the kitchen floor in the attached two images. Good luck with your specifying . High quality surface finishes normally stand the test of time . I have added a couple of extra images of the penthouse for interest. We did the interior design fit out after buying the shell from the developer. It was a stunning sky home . Cheers LAADP

I would inlay it into a frame..ie with a base to hold the marble..then that way you can screw/weld the legs to the base of the frame..

Lots of ideas here https://www.google.com.au/search?q=How+to+build+a+marble+table+from+an+offcut&ie=UTF-8&oe=UTF-8&hl=en&client=safari
