Do kitchen cabinets go in before flooring. The flooring contractor will not have to work around existing cabinetry so the work can go that much faster. The floor covering will be cut to size and almost butted against the cabinets. If they want to change flooring at a later date you dont have to remove the cabinets. Put all the base cabinets in place then mark a line on the subfloor corresponding to the front edge of the toekick.
Those are all good reasons to lay a kitchen floor after the cabinets are in. Keep in mind however that whichever method you decide to use there are both advantages and disadvantages. Installing the floors before the cabinets has some advantages. Cabinets are installed after the finished floor.
If you have an installer doing this for you i would highly recommend discussing your options with them as they are the ones on site. Floor covering or finish flooring is the surface that you see and walk on not the sub floor and not an underlayment. Otherwise the cabinet toe kicks and countertop will be short. Install your cabinetry and shelving space first.
If installing a floating floor the answer is simple. There is one exception to this rule see below. Shim up base cabinets keeping in mind the underlayment and flooring thickness the base cabinets should be raised up to accommodate the thickness after installation of the floor. There are a couple quality items to consider when installing the cabinets before flooring.
All you have to do is pull the kick off remove the old floor covering install the new flooring then put the kick back. However when installing a wood flooring nail down or glue down there are more factors to consider. Whether you want the kitchen cabinets to go in before the tile flooring or the tile flooring to go in before the kitchen cabinet is totally up to you because there are no set standards that dictate which of the above should go first. But if you have to install the flooring first heres a method that will avoid some of the problems i just described.
As you can see above there are pros and cons to installing the flooring before or after but there seems to be less risks by doing the cabinets first. The best way to accommodate your floors shelving and appliances is to work in this order. Install the cabinets first because heavy cabinetry cannot sit on top of a floating floor or it will restrict movement and increase the chances of flooring separation.
