Installing a corner shower unit can make efficient use of your bathroom and often offers a larger internal area so you don't bang your elbows off the walls while you are washing. There is a large range of corner shower units available from home improvement stores and they're not difficult to install yourself. Simply follow the step-by-step instructions below.

Step 1 – Install Plumbing

If this is a new shower installation, you will need to install hot and cold piping supplies to the wall where the shower unit will sit. Connections for the shower head and valves need to be positioned in the appropriate places ready for you to add the fixtures after the enclosure is installed. If you don't have plumbing experience, it is recommended that you get a professional to install the pipes for you.

Step 2 – Install Drain

Unless you are replacing an old shower, it is likely that you will need to install a new drain assembly for your corner shower. In order to fit this drain system in, you may need to build the shower up on a pedestal if there is not space under the floorboards. Connect the drain output to the waste piping that runs from your bath or sink. Make sure that these connections are tightened and no water escapes. It is much easier to solve a leak before you install the rest of the shower unit.

Step 3 – Install Base

Check the manufacturers instructions to see what measures you need to take to level the floor before installing the base. In most cases, a layer of ¾ inch plywood is sufficient but some require a layer of foam insulation as well. Attach the base to the walls with adhesive after leveling it off with wedges underneath, if necessary. Weigh the base down with bricks to hold it in place while the adhesive sets. Fit the cap on the drain assembly and seal the joint using plumbers putty.

Step 4 – Install Wall Panels

Measure the distance from the base unit and the corner of the wall to the position of the pipes for the shower controls and shower head. Transfer these measurements to one of the wall panels and use a hole saw to cut the appropriate holes. Verify your measurements before making the cut because if you get it wrong, you will probably need a replacement panel. Once you have made the holes, attach the panels to the wall using panel adhesive. Begin attaching from the base unit so that it is a tight joint. Press the panels into place using 2x4s braced against the walls.

Step 5 – Attach Frame

Install the frame and glass panels into the enclosure then add the door assembly. Use the manufacturers instructions to ensure that everything is in the correct place as there are many different varieties of frame. Use silicone caulk to seal the tracks and panels into place then seal all of the joints between the walls and floor and the enclosure. Take your time with the sealing process as any gaps can cause you many problems in the future.
