Bathroom Wall Construction and Framing

Constructing an Architectural Partition

You might be considering the addition of an extra non-load-bearing wall in your bathroom but have no clue as to how bath walls are constructed and framed. Learning wall fabrication terminology will be your first step to understanding how washroom walls are built.

Knowing things like framing members in the floor and ceiling are called joist will go a long way to successfully erecting a wall. Look no further, this article will take you through easy to follow steps that will show you how to frame and build a new wall in your lavatory.

Continue reading, and before you know it, you will have all the necessary information needed to get your project on its way to either replace your old and damaged interior walls or simply just to expand your bathing space.

Before you begin any project, it is important to note that some municipal building regulations stipulate that a room such as your bathroom should have at least one window that gives access to the outside of the property if possible. So if you were planning to divide your grooming space in two using a partition, mapping a slot for an extra window is a good idea.

Assembling the Tools Needed for Fabrication

With that said, here is a list of equipment and materials you are going to need to frame and begin the assembly of your new wall:

  • Tape Measure
  • Hammer
  • Drill (optional)
  • Pencil
  • Circular Saw
  • 2”x4” boards
  • Saw horses
  • Spirit Level
  • Plasterboard
  • Nails
  • Screws (optional)

Now that you have an idea of what you are going to need for framing your bath wall, it is now time to follow this simple tutorial to begin the erection of your new partition.

First of all, before you begin the construction process, decide exactly where you want your new wall to span. You will need enough pieces of lumber to stretch from one wall to the other.

Establishing the Correct Dimensions

To determine the length of your bathroom, use your tape measure to obtain the figures and then use your saw horses to hold your 2”x4” boards in place while you cut with a circular saw until you have the appropriate length of lumber to span the gap from one wall to the other.

Next to proceed with your project, begin nailing the 2”x4” boards that were cut on the floor. This is called the sole plate and will be the foundation for your new wall partition when framing your bath wall.

When you have finished nailing in place your sole plate, continue the building process by taking out your spirit level and 2 lengths of lumber. Raise one length vertically on your sole plate and place firmly against one side of the wall.

Make Sure the Edifice is Straight and Level

Use your level to ensure that it is straight and take a pencil and begin marking a straight line up the board on both sides. Repeat the following process using the other length of board on the opposite side of the wall.

The next stage in your wall construction is to check which way your ceiling joists are running. If they run opposite to the wall partition you are going to place, simply use your measuring tape, and circular saw to cut enough 2”x4” board to fasten a head plate on the ceiling that is perfectly aligned with the sole plate on the floor.

When fastening your head plate to the ceiling, use screws since nails might damage plastering. The lines you previously marked on the side of the walls will be your guide when fastening your head plate.

Compensating for Joist Direction

On the other hand, when erecting a new wall in your washroom you may find that the joists in your ceiling run the same direction as the partition you are going to construct, a little more work is required.

No need to worry, all you have to do to rectify the situation is attach noggins between the joists to support your head plate which will only set you back less than an hour to measure, cut and fasten to bring your bathroom wall construction project back on track.

Ok, as you can see bath wall assembly is pretty much straight forward as long as you plan ahead and proceed methodically. After your sole plate and head plate are securely fastened and perfectly aligned, its now time to begin inserting your wall studs.

Let’s proceed with the fabrication process…Before cutting your studs, ensure that the measurement of the stud is a couple of millimeters longer than the distance between the sole and head plate. Though you will have to use a hammer to knock the stud in place between the two plates, it will make your wall frame sturdier and will also make it an easier job to nail them in place.

So start with placing your first two studs at both ends of your wall; if you are attaching your new wall to concrete, use wall plugs and screws to securely fasten the studs. Also, when fastening your studs to the sole and head plates, use a technique called skew nailing whereby you drive nails or screws from an angle into the studs to fasten them securely into the plates to create a solid structure.

Determining Spacing Between Studs

Moving along with the framing procedure…after you have securely put in place your first two studs, you will have to determine the spacing between the other studs that will be inserted.

Ordinarily, studs are spaced based on the size of plasterboard as well as the position you will be placing them (vertically or horizontally). For instance, if your wall panel is 1200mm x 2000mm the ideal spacing of the studs would be 400mm.

Now that you have sorted out your stud spacing, begin using the skew nailing technique to fasten them securely to both the sole and head plates. After completion, start adding noggins in between of the studs.

This can be done in a straight line, or you can fasten the noggins in an offset position to make nailing easier. At this juncture, your wall frame has been completed and its now time to begin adding your plasterboard panels.

Adding Paneling to the Enclosure

To finish constructing your bathroom wall, as stated before, when adding your wall panel it can be placed either vertically or horizontally. Based on the stud spacing, decide which position best suits your project and begin fastening the plasterboard unto the studs using broad headed rust proof nails or bulge headed plasterboard screws.

If you want to place a door opening, simply leave an opening with studs on both sides and fit the door casing unto the studs. So after you have driven nails or screws into the plasterboards and ensured that they are securely anchored into the plates, studs and noggins, your new bathroom wall construction and framing project has reached its conclusion.

Whether assembling new walls from scratch or tearing down and reconstructing your bath walls, following this informative guide will give you a sound foundation for you to successfully complete the erection of an interior wall within your bath. All it takes is the right equipment and this easy do-it-yourself tutorial to set the foundation to create the bathing space you’ve always wanted.
