Things You'll Need
Fiberglass corner tub
Tile or drywall
Corner bathtubs let you install a large tub in a small space. Installing a fiberglass corner tub is a project that will take several days to complete. Additionally, you may find it difficult to get the tub into the bathroom through the door. You may need to remove finished walls to get the tub into place -- and you will need a helper for the installation. Homeowners who are uncomfortable with undertaking a plumbing project should consult a plumber.
Replace any damaged subflooring in the bathroom. The fiberglass corner will need a level and sturdy base.
Locate the plumbing in the room and ensure that the fittings are in place for the tub. Hire a plumber if you are inexperienced or uncomfortable with proper plumbing techniques.
Build a wood frame for the corner tub. Each manufacturer requires different framing instructions, so refer to the installation directions that came with the corner tub. Use the specifications in the instructions, a hammer, screwdriver, lumber and screws to build the frame. Use a stud finder to locate wall studs in the bathroom corner where you will be installing the tub.
Lift the tub into place in the corner of the room with the help of a partner. Set a long level across the top of the tub. Adjust the tub until it is level by putting wooden shims under the tub.
Screw the tub into place with a screwdriver and galvanized screws. Place the screws through the nailing flange and into the wall studs.
Connect the overflow assembly to the drain connections on the tub with a wrench. Follow the manufacturer's directions or call in a plumber if you are uncomfortable making the connections yourself.
Finish the wall above the tub and the tub framing with tile or drywall.
