Laundry room



Below are some of the key considerations an architect, builder or owner should make before designing a laundry room for today’s multi-unit properties.

Laundry Room Planning
When designing laundry rooms, location is the primary concern. Residents prefer laundry rooms within easy walking distance from their apartment units. The laundry room should be near main traffic patterns; not in secluded, remote areas that pose security problems.


  1. Determine the size of the laundry room by allowing a minimum of 25 square feet per machine.
  2. Floors should be concrete with a troweled finish and sloped toward the floor drain. At least one floor drain should be provided per laundry room.
  3. Provide a minimum clearance of 8′ between floor and overhead pipes.
  4. Locate dryers on exterior building walls. Long ducts increase installation costs and are less effective for proper venting.
  5. Provide sufficient lighting. Fluorescent lighting provides 2-1/2 times the lumens obtained from incandescent lighting (i.e. a 40 watt fluorescent is equal to a 100 watt incandescent).

The type and number of washers, dryers and other equipment required will depend upon the following:

  1. Family composition of the occupants
  2. Number of apartments to be served
  3. Presence or absence of children
  4. Number of laundry rooms in the building.

Please consult your Dadson sales professional for equipment recommendations.

Washers recommended
Energy efficient 14-16lb., heavy-duty commercial washers are recommended.

Dryers recommended
There should always be one energy efficient, single load dryer for each washer.  When more than one dryer is required in a laundry room, stacked dryers may be used.  Double Load dryers consume more energy and space, generating less income.

Use the following guidelines to determine equipment needed for each laundry room location. The number of machines required are effected by the following:

  • Resident profile (families, singles, elderly)
  • Price charged (consult Dadson for pricing recommedations)
  • Proximity of units to laundry rooms

Equipment Guidelines

Tenant profile Number of Washers and Dryers per Apartment unit
Families Washer/dryer per 8-10 units
Young working adults 1 washer/dryer per 10-15 units
Older working adults 1 washer/dryer per 15-20 units
Students 1 washer/dryer per 25-40 units
Senior citizens 1 washer/dryer per 25-40 units
  • These figures are based on the predominant resident profile. Adjust according to your particular profile mix.
  • Units that would use a central laundry rooms washer and dryer are determined by adding together all units without an in-unit washer/dryer and half the units with in unit laundry connections.
  • For further assistance please contact your local Dadson representative.

Design Guidelines

Dryers: Start with dryer location when developing a room layout. Dryers should be situated on an exterior wall for most efficient venting. Walls behind dryers must meet required fire ratings.

Floor and drainage: Always use concrete floor that slopes toward a floor drain.

Water Heaters: Water heaters should be placed near washers and protected by proper fire-rated walls.

Security: Laundry rooms should be designed with safety as the top priority. This includes planning entryways on main traffic patterns along with using glass windows, walls, or panels to provide total visibility and eliminate screened areas. Change machines and soap dispensers are not recommended.

Lighting: Rooms should be well lit, fluorescent lighting is recommended.
