That’s not the only problem. The basement is usually the farthest place from the bedrooms, so you’ll be lugging laundry from one end of the house to the other.

If your laundry room has to be situated in the basement, be sure it gets plenty of fresh air with a ventilation fan and an exhaust fan.

2. Forgetting to slope the floor

Here’s hoping you don’t have to deal with any water problems in your new laundry room, but it’s a mistake to assume they won’t appear. Elron says many people fail to design the laundry room with a simple slope toward the drain.

“A level floor will just hold water if there’s a leak or an overflow, but having a slope toward the drain will help remove this water from your floors,” he says. “The general consensus is to have, at a minimum, a quarter-inch slope per square foot of laundry room.”

If you’re wondering if the floor is going to look and feel awkward, Elron says it’s barely noticeable.

3. Not leaving enough space for dryer ventilation

Dryer ventilation is important to prevent a dryer fire, but many times, the appliances are wedged in too close to the wall.

“This can raise the risk of a dryer fire sparking due to excessive buildup and inhibited airflow,” says Jason Kapica, president of Dryer Vent Wizard. He recommends leaving a few inches between the appliance and the counter to allow for cleaning around the machines.

“Additionally, the washer and dryer can then slide in and out easily when a yearly inspection of the machine and the dryer vent is required,” he says.

4. Not making the layout functional

There’s more to your laundry room than just washing and drying clothes, but this doesn’t dawn on many homeowners until it’s too late.

“The laundry room is a utility room, a place for sorting dirty clothes, folding clean clothes, and storing cleaning and laundry supplies,” says Leslie Saul of Leslie Saul & Associates, an architecture and interior design firm in Cambridge, MA. So the design of your laundry room should accommodate these functions, too.

Install shelving or a cupboard above the washer and dryer, and make sure there’s plenty of space for laundry baskets.

“If space is at a premium, consider a fold-down, hotel-style press or wall-mounted ironing board placed as close as possible to your dryer so that you can easily move newly dry clothing items directly to the ironing board,” suggests David Ewart, director and interior designer at Pavilion Broadway in Gloucestershire, U.K. “This can keep clutter levels to a minimum and ensure you are able to operate within even the tightest of confines with minimal effort.”

5. Not providing enough light

This is another area that doesn’t get a lot of attention during the planning phase.

“When designing a laundry room, don’t forget to provide enough light so that you can see the stains more clearly,” Saul says.

Also, a frequent complaint about appliances that have digital displays is that the control panel is often hard to read in dim light, which is another reason to make sure the room is well-lit.

“One center light fixture usually isn’t enough; two might be better,” Saul says.

6. Failing to consider a multipurpose room

Depending on how big the room is, it may be a mistake to dedicate it solely to laundry tasks.

“This space could also be used as a gift-wrapping station or a place to use and store crafts supplies,” says Los Angeles–based interior designer Sarah Barnard.

Another idea is to add a bench and cabinets and have the laundry room serve as the mudroom, where the kids can take off their soiled shoes and wet outerwear.
