Can You Install Cabinets On a Sloped Floor?

Kitchen cabinets can be installed on sloped floors by adjusting the kick legs. The 4 legs under individual cabinets can be individually adjusted for height to install cabinets on uneven floors. Shims are used on cabinets without leg levelers.

Installing kitchen cabinets always seems like an easy task. In reality, there are plenty of instances when it’s simply not possible to install kitchen cabinets are uneven in multiple places or if the slope is too steep.

However, most kitchen cabinets can be installed with a bit of creativity even when floors aren’t perfectly flat.

Can you install cabinets on an uneven floor?

Leg levelers are specifically designed to install kitchen cabinets on uneven floors. They adjust from 4 sides so that the countertop is flat. A screwdriver is needed to rotate leg levelers and move them up or down for leveling.

What is too steep in a slope? When to level out floors for cabinets?

First, can you install kitchen cabinets on all slopes? What’s considered a maximum floor level difference on which you can still build on?

A floor difference of 2-3” is considered too tall for leveling kitchen cabinets with adjustable legs. Leveling up the floor is required when variations of more than 3” exist between the legs of the kitchen cabinet.

How to install cabinets on a sloped floor when cabinets don’t have legs

But what about kitchen cabinets that don’t have legs? Not all kitchen cabinets are made with height-adjustable legs.

This is why it’s crucial to find the right strategy for your floor when you don’t have legs. At the same time, some of these solutions might also be applied to kitchen cabinets that have self-leveling legs as well.

Build a sub-base

A sub-base is a type of understructure built under kitchen cabinets. Typically designed from wood or metal, a sub-base for kitchen cabinets evens out uneven floors.

Of course, for a sub-base to look good it has to be considered for small uneven differences of up to 2 inches.

A sub-base typically has 4 sides, for each panel of the cabinet. 2-side sub-bases are also popular when the uneven floor only has one slope to counter such as a lower back (towards the wall), a lower front, towards the kitchen, or a slope to the left or right side of the kitchen cabinet.

Build a leveling deck

A leveling deck can also be used to level uneven floors. This solution is very common for an outdoor kitchen where a slope can be higher.

A leveling deck is mostly made out of wood. It compensates for uneven flooring by creating a ‘false’ floor.

This solution is not as elegant when it comes to implementing it in an indoor kitchen. However, even the indoor leveling deck can be masked so that your kitchen can look spotless.

Add shims

Shims are always used under kitchen cabinets. They represent one of the cheapest methods of leveling cabinets on sloped floors.

Why you might not want to install kitchen cabinets on uneven floors?

Too much uneven floor compensation by using a deck, shims, or a sub-base might not be the ideal solution for uneven floors.

Of course, leveling up the kitchen floor entirely is the ideal solution. It’s also the most expensive solution to uneven kitchen cabinets. Here’s why you might still want to go with the permanent fix.

A taller countertop

A slightly uneven floor will not raise the countertop’s height. However, a considerably uneven floor might add a few inches to the height of the countertop which might make it a bit uncomfortable to use.

Solutions such as building a small deck under the kitchen cabinets also add height inches. All of these are important and it’s crucial to limit the height of the cabinets.

Unaesthetic look

If you aren’t using some crowning you might as well consider leveling up the floor entirely as all solutions will be visible and unaesthetic.

One of the reasons why you’d want not to use crowning is for proper vacuuming and mopping. If you’re the type of person who likes all furniture to be on legs so that robot vacuums clean all floor surfaces you will not use crowning.

Extra cost

All of these solutions cost money to implement. Some are cheaper than others. Sure, a few shins aren’t going to cost much. But more expensive wooden decks are going to cost a few hundred dollars which is about the cost it takes to level the kitchen floors (without tile).

The floor remains uneven

Even if you compensate for uneven floors they remain uneven. These don’t create an aesthetic look and they can deter from the value of a home.

Summary

You can install cabinets on sloped kitchen floors. The easiest way to do this is by adjusting the leveling feet of kitchen cabinets. Shims can be used on kitchen cabinets that don’t have leveling feet. Alternatively, you can add leveling feet to kitchen cabinets.
