Marble Bench?

Marble is not the best stone for outdoor use. It is a softer stone and will etch and stain easily. Since these were tabletops, I'm guessing they are polished marble which is not suitable for outdoors.

I gave some to my neighbor and they made patio tables. They built a wooden frame to hold them. Build a top frame like a picture frame to keep them from sliding and drop them in. Build STURDY legs. I see people use coffee tables to make benches. They were NOT built to hold the weight. Use repurposed furniture legs.

Tracey: a caged rock base like these might work

I agree, the marble is soft and not suited for the outdoors. It will loose it's shine and color over time & it will also stain easily because it is porous. The weather will erode away any finish on it, eventually making it less attractive. Still if you want to put your marble outside, it will need maintenance with a polishing compound and this needs to be done regularly. You will also need to seal it so water cannot get in and cause cracks and damage. Best to you.

If you build legs or a frame out of wood make sure you use cedar or pressure treated so it doesn’t rot outside.

You would need a suitable frame if they were actually going to be sat on, as they will break. You might also want to position them in a shady area as the sun beating on them all the time can break them down faster..

When you make a wooden frame and legs put a 3/4" plywood under the marble for support or it will break. I made end tables out of cedar and a 13x13 floor tile. Nobody is sitting on it, but photo shows example.

Hi Tracey,

Sit on Brick piers or use Cinder Blocks.............Very nice contrast! Lucky you!!

Wood, even outdoor lumber, will not last forever. Stone/concrete is your best bet.

We had an old cement bench that broke (the part you sit on broke but the legs were just fine). We used those legs and out a new top on it. The top was just cinder block but after hubby notched out the spot where the legs fit into the cinder block it fit like a glove and has been used for years in our front yard.

Hi Tracy, here are a few videos that will hopefully help you,

You may be able to do something with cinder blocks as well

I think these would look nice, but maybe they'd hold up better on a covered porch or an area with less direct sunlight. I would see if you could find someone to build a wooden base for them that would work for outdoors. Marble is quite heavy and you'd want it to fit snugly on something that is secure.
