I highly recommend that you consider renting a laser level from a local rental store to get the installation off on the right foot. In all honesty, this is going to give you the most accurate level line possible.

You will find that it is very easy to set up, and after you have found the high spot in your floor, you can shoot the laser line at that spot and go from there. By marking the inside corners of the walls where the laser line is visible, you can use these as a reference point.

Now you can use a chalk line to snap lines between these laser marks. However, you will want to be sure of one thing here. You will need to make sure that you pull the line as tight as possible here. By doing this, you will be sure that the line will not have sagged in the middle of the wall. Double check the lines by using the laser level again, making sure that the lines match up with each other.

Now, if you do not have a rental store nearby, then you can use a four foot level to get the same results. If you do use the four foot level, you will need to be very accurate with it.

After you have determined the high point of the floor, you can go ahead and draw the level lines around the walls. If at all possible, have someone else help you with holding the other end of the level while you level it up and draw the level lines along the walls.

By the time you get to the end of the kitchen walls, flip the level end for end and work back to the beginning. The accuracy of the level will be determined once you get back to the mark where you started drawing out the level lines. An accurate level will be determined here by the level lines matching up. If you find that the lines are not lining up, your level is not accurate and you will need to purchase a new one.

When you rent a laser, you will avoid any of these problems. It will save you some time at the beginning stages of the installation, but it will be the very best way to give you level lines to start with. This step is just like the foundation of any structure or building. This is where you need to pay close attention to detail.
