Does Lowes have washers that fit under the dryer stand?

I am assuming you already have a stackable dryer and need only the washing machine . If you need both units, they are sold in matching pairs with the stand buil-in to the washing machine frame. I all you need is a washer, then Lowe's has several washers that can be used. Do a product search for "stackable washer." Browse and select a unit that interests you. Then click on the SPECIFICATIONS tab and write down the dimensions. Measure the height, depth, and width of your existing dryer. Add the heights to make sure there is enough room from floor to ceiling that the units will fit. Then measure the depth and width to ensure there is enough lateral space where you will install them. You will also need at least two very strong helpers to complete the installation. Or you may contact your local Lowe's appliance department for recommendations to install. There are also stackable sets where the dryer stand is built into the washer.
