Prefabricated shower stalls revolutionized the way showers are installed because they can be put together in two or three pieces or installed as one full shower/tub. They now come in many different types and, in some cases, even with a tiled finish.
There are many advantages to installing one of these in your home because they provide an almost instant solution to a problem and, in many instances, is a perfect do-it-yourself project.
The type of shower depends on where the bathroom is located and the main purpose of the unit. For example, an ensuite may have a shower/tub unit whereas a guest bathroom may suit a shower stall. This project details how to install a modular shower stall.
Before starting make sure that the basic plumbing is up to code. If replacing an old shower stall then this is made easier because the drains and water inlets pipes will already be there. If starting from scratch hiring a licensed plumber to get the utilities in order or the installation may not be legal.
A one-piece shower is moulded from fibreglass or acrylic must be installed in a framed opening. Before purchasing, make sure you can get it through the doorways and into the bathroom.
A modular shower unit has two to three pieces and can be fitted into areas where a single unit could not be brought in.
If renovating studs that held the old shower unit may be adequate for the new installation however check the information included with the shower unit to see if additional studs need to be inserted.
Build the walls for the shower using 2" x 4" framing, with studs placed 16" on centre. Install the supply pipes and the drain, using the measurements included in the manufacturer's instructions to mark the locations.
If installing a 1-piece shower, leave off the 2 outer studs on the wall until the unit is in position. This gives you room to manoeuvre the unit.
Many units come with clips that are installed on the studs and made to hold the unit secure.
The minimum height for the shower controls should be 38" above the floor while maximum height should be 48". This is included in the building codes in many areas.
There is no minimum or maximum for showerheads in the building code but the standard is usually 72".
Make sure the subfloor is level. If the base cannot be shim, install a bed of mortar cement to level.
For a renovation project, make sure to select proper shower material according to the space available and position of the drain.
For a new construction, build a plumb stud structure according to the shower stall specification measurements.
