Basement Shower Drain Installation

Basement drains typically are installed during home construction because they allow rain and water to drain from the basement floor before roof installation. It's best to install a basement drain before the flooring and basement are finished, because once they have been installed, installing a drainage system is more difficult and expensive. Luckily, you won't have to worry about installing a drainage system if your contractor installed one during construction. You can then build your shower around the existing basement drain. Before you can install the drain, an excavator must dig a trench that leads away from the foundation.

Instructions

- 1
  Lay the drainage pipe in the exit drainage trench. The pipe just has to lie flat in the trench, and other pipes will be connected to it afterward.
- 2
  Lay the drainage pipe on the inside of the concrete footings and out through the hole in the footing. Another drainage pipe should go along the outside of the concrete footing. These two drainage pipes are then connected together with the appropriate-sized fittings.
- 3
  Connect the inside and outside drainage pipes to the pipe in the exit trench, using the appropriate-sized fittings.
- 4
  Choose an appropriate basement location where the drain is to be placed and saw a small piece out of the drainage pipe. Install a T-adapter that will stick up through the floor.
- 5
  Surround the drainage pipes with crushed gravel to prevent sand from entering through the drainage pipes. Fill the floor with crushed gravel, or cover it with concrete. The basement drainpipe can then be cut down to size and a drain covering can be glued on top of the drainpipe.
