Yes but, make sure to explain your plans to the cabinet maker & installer. Maker needs to know exactly where in the island the outlet will be wanted so he can allow space / not interfere with a drawer etc.. Be aware that any caulk applied between the island and the tile will damage the cabinet's surface. Live with the "gap" or be prepared to add molding when you change the floor.

If the electrical cable is going to run on the outside in a conduit, then sure, but that's a hillbilly solution. If it's going to run inside, then the only solution is that he'll need to move the island and put it back.

An island needs electricity to even meet CODE. Do it all now. I would also say, post the existing kitchen and make certain you even truly have ROOM for an island. Not every kitchen is meant to have an island. That is why many had a peninsula. Instead: )

I would get an estimate for getting it done now before island. & 1 for how much after. I imagine it will be less $ & less probability of problems do now, than later. The best sequence is to get it done beforehand.

Figure where the trench needs to be. Where it will intersect the island. Likely that'll be on a side with toe kick. Have the island built with the pop-up or other receptacle installed with any conduit down to the toe kick. Make the toe kick removable at that location or area. That should be sufficient for a future install with no damage to the island.

Always do the difficult messy stuff immediately after demolition. Not with any finished surface in the way.

IMO a moveable island would be a much better choice in this situation but be aware this will only be used for prep and seating so choose wisely. The other option as mentioned is trenching and you will need to prepared to redo your floor since the chances are you do not have enough of the old tile to redo the trnch area .

The reason you need electricity in an island is to not run extension cords to it .

Hi there, I know this thread is a year old, but I was wondering how your remodel went? We are going to be remodeling our kitchen from a U shape with peninsula to a L shape with Island. We want the island to have electrical outlets (mainly because of code and convenience) in it but I am not sure about trenching the concrete. My concern is that the slab is PT. Any recommendations? Anyone from Las Vegas do the same? Thank you!

Thank you live_wire_oak. We are still not sure if the slab is post tensioned or not. In the case that it isn’t... is such an undertaking as difficult?

Nat, we've cut our slab on two diff occasions. one when we put in an island and ran the electrical from the wall, slab cut a trench to island. you can rent a saw and do it yourself in a few hours. It's very messy since you have to keep the blade wet while cutting.

we are on a slab built in 1980. Rebar but no post tensions.

second time was cutting the slab 35 feet for a sewer pipe for new bathroom remodel. Now that was an undertaking.

(this slab has been through numerous large earthquakes, so no issues w/the foundation. )

luckily I found a guy who did commercial slab cuts for a profession. he brought his huge commercial saw and trenched this in 3 hours. Would have taken us days w/the smaller one. Best part was the cost. $400. we lucked out on that one. It's good to know people.

on another job I did, had to move a water heater and we had the floor 'x-ray'ed and found post tension wires. we were able to trench around it. So if you're unsure, find someone who can come out and 'read' the slab for you. I can assure you it doesn't cost 20K. not for an island. I can't remember what we charged for the other job, maybe an additional 1-2 K for the slab cut/reading. it was included in w/the plumbing bid. Just depends on how long the trench is and the wiring involved.

That's awesome Beth!! Thank you!!

Thank you for the info Beth! We too are putting in an island. We currently have a gutted kitchen will make it easier do the trench.
