How to install a corner shower.
Obtain a corner shower kit. The kits come with the glass sides and door, the base and some water proof sheets for the other two walls. I have assembled ones from both Home Depot and Lowes. I don’t see much difference so get the one that you prefer.
Begin by locating the drain. If you are working with an existing drain, you may be limited. If not then plan you drain layout first and install the drain pipes with an appropriate trap. Most of the kits come with a drain fitting that will slip over a 2 inch pipe.
You will need two solid walls to form the corner for the shower. If you already have a corner then you can use that. If you are mounting the shower along a wall, you may need to build a new wall to form the corner. The new wall can be faced with sheetrock. The shower panels will glue over the wall to make it water proof.
Once the drain is in place securely mount the base. Make sure the base is level or at least drains to the hole. Pack gout or sand under the base to make sure it is firmly supported. Screw or press the drain in place and caulk it to the base.
If you are using an existing wall, cut back the sheet rock so that the base will be against the studs. If you are building a new wall, push the base against the studs and set the sheet rock on top of the base flange.
Install the shower faucet and plumbing. Be sure to test it all for leaks before sealing up the wall. I recently had a brand new faucet fail to shut off causing quiet a mess.
Make a cardboard template from the shower box to locate the holes for the shower nozzle and the knobs. Mark these on the sheet rock for the wall and on the plastic water proof sheet that will be on that side.
Set the corner piece up and mark it on the wall. Remove it and put glue o the wall for the water proof sides. I used the appropriate styrene compatible glue in a caulking gun to secure the walls to the sheet rock. Tape them in place to make sure they don’t sag. Make sure they are level and vertical.
Apply glue for the corner piece and glue it in place. Make sure you insert the towel bar (if it has one) before gluing it up.
Install the faucet knobs and trim, Install the shower head.
Mount the first track for the glass wall making sure it is vertical. Then mount the second one. Choose which way the door will hinge and install the magnet closer strip on the appropriate side. Attach the strips above and below the door opening to that side.
Install the glass wall in the end strip. Assemble the hinge side and slip it into place. Adjust the pieces so that they sit in the center of the base flange. Level the walls and anchor them to the end strips with the provided screws.
Cut the top piece to the correct length and bend it over the top of the walls. Anchor it with the provided screws. Be sure to compare the screws to the instructions so that you are using the correct length fasteners.
Attach and top plates that are provided for stiffeners. Then attach the lower hinge plate. Set the door in place and install the upper hinge plate to secure the door. Adjust the hinges so that the door swings smoothly.
Caulk the joints where the metal frames contact the plastic parts. Allow the caulk to set before testing the water.
