Wall utilities — switches, outlets, safes — small wall fixtures with conventional symbols and mounting heights.

3 min readUpdated 2026-10-28

Switches, outlets, and wall safes are small wall-mounted fixtures with conventions for placement and symbols.

In this guide

  1. 1

    Light switches

    Mounting height: 48 inches to center above floor (standard); 44 inches for accessibility. Placement: next to the latch side of room doors, on the room-interior side. Types: single-pole, 3-way (two switches one fixture), dimmer, smart switch. In RoomSketch3D: switches aren't in the Build panel. In the Furnish catalog (Fixtures category) search switch and pick Light Switch (3D), Double Light Switch (3D) or Dimmer Switch (3D), then tap the wall; it goes in at 46 inches to its bottom edge; there is no separate smart-switch fixture — for the plan, the Symbols tab has Switch (Smart), Switch (Dimmer) and Switch (4-Way) symbols.

  2. 2

    Electric outlets

    Mounting height (general): 12-18 inches above floor for standard; 42-48 for kitchen counter outlets; 24-28 for bathroom. Placement (residential code): no point on any usable wall more than 6 feet from an outlet — outlet at least every 12 feet of wall. Kitchen counters: every 4 feet. Types: standard duplex, GFCI (bathrooms, kitchens, outdoor), USB-integrated, smart outlet. In RoomSketch3D: outlets aren't in the Build panel either. In the Furnish catalog (Fixtures category) search outlet and pick Duplex Outlet (3D), GFCI Outlet (3D) or USB + Outlet (3D), then tap the wall. There is no separate smart-outlet item.

  3. 3

    Wall safes

    Mounting height: 36-60 inches to bottom of safe. Behind a hanging picture is common. Standard sizes: 12-36 inches wide × 12-24 inches tall × 6-16 inches deep. Wall depth required: safe depth + 4 inches for installation. Standard 4-inch interior walls cannot accommodate most wall safes; need 6-inch walls minimum. In RoomSketch3D: in the Furnish catalog search wall safe and pick Wall Safe (16 inches wide), then tap the wall. Select it to set its Width, Height, Depth (how far it goes into the wall, limited by the wall's thickness) and Mount (the height of its bottom above the floor).

  4. 4

    Placing them on a wall

    All three place the same way: pick the item in Furnish, then tap a wall (a picked item waits for a wall tap rather than dropping into the room). On an interior wall, a switch or outlet lands on the face you tapped from; pick In or Out in its panel to move it to the other face. Drag it along the wall to move it. For a 2D electrical drawing with standard symbols (3-way and 4-way switches, smart switches, 240V outlets and more) use the Symbols tab instead; see electrical plan outlets switches symbols.

Tips

Switch goes next to the door's latch side

As you walk through the open door, your hand naturally falls onto the switch.

Frequently asked questions

How high should light switches be?

48 inches to center is standard residential. 44 inches for accessibility.

How far apart should outlets be?

Maximum 12 feet between outlets along any usable wall.

Can I mark switches and outlets in RoomSketch3D?

Yes, two ways. For switches and outlets you can see in 3D, search switch or outlet in the Furnish catalog and tap a wall. For a 2D electrical plan with standard symbols, open the Symbols tab (next to Indoor and Outdoor on the right, or the Symbols pill on a phone); it is always there, no setting needed. See electrical plan outlets switches symbols.
