How to Vent a Basement Shower

A shower in a basement must be vented to prevent gas smells and other odours from coming in through the drain. Venting is also needed to remove excess moisture that can lead to mould from collecting in the shower.

A basement shower can be vented by first determining how the existing vent pipes are connected in the bathroom. You can then route a new vent pipe to the drain pipe for the shower. First, you’ll need to locate the vent pipe running from a toilet or sink in the wall and up through the ceiling. Professional plumbers (υδραυλικοί) could give you really helpful advice!

Cut out a section of vent pipe, using a hacksaw or a reciprocating saw. Glue the ends of the tee fitting with PVC glue and attach it to the vent pipe. The tee fitting is the piece of 90-degree pipe that has three connections.

Cut out a section of drain pipe and attach another tee fitting.

Run a PVC pipe from the tee valve to the tee fitting. Glue the ends of the pipe with PVC glue and attach them to the tee fittings.

Attach a small section of PVC pipe to the tee fitting on the drain pipe and run it to the location of the shower drain.

Attach a P-trap to the end of the PVC pipe for the shower drain to complete the vent for the basement shower. The P-trap is the U-shaped piece of pipe.

How to Install a Basement Shower

One of the best returns on your basement remodelling dollar is the installation of bathroom features. A basement shower will raise your home’s value and provide a handy amenity. Due to the sub-grade environment, however, you will have to take precautions regarding water damage when you install your shower.

Locate the drain that was installed when the concrete for your basement was poured. This is a pipe that sticks out of the floor, often with only sand surrounding it. Your drainage will run into this pipe. Although you may locate the shower anywhere in the basement, most people find it easier to place the shower close to the drain.

Locate and design your basement shower so that it will be easily accessible.

Break out a section of flooring where you want to install the shower plumbing. When the basement contractors poured the concrete, they reinforced it with rebar or mesh. Remove this reinforcement to provide space beneath the shower drain to install the trap.

Ventilate your shower drain into your home’s outside vent stack if possible. If it is inaccessible, purchase and install an auto-vent for the trap that uses a rubber flapper to promote smooth drainage. Without proper shower plumbing, your drain may overflow, resulting in water damage.

Frame in the support structure for your shower. If you use a fibreglass shower enclosure, refer to the manufacturer’s specifications for constructing the frame. Install the plumbing for your water source in an interior wall in order to place an access panel in the adjoining room for easy access.

Consider any future remodelling plans you may have for your basement when placing the panel. Insert and secure the fibreglass enclosure panels and double-check your shower plumbing by running water into the drain and observing any leaks. Address all leaks before proceeding, or you may experience water damage later.

Attach faucets and a shower head. Finish your new basement shower with a curtain or an attached shower door, both for privacy and to prevent water damage.

If you are thinking of remodelling the basement at home, a new bathroom there is a great idea. Finishing or upgrading the basement into a living space continues to be a popular alternative now. A basement shower will be a very handy and useful amenity especially if your family members are increasing.

You will be able to recoup the costs of your basement in the future since you’re home’s value increases with this added feature. There are some precautions to make since basement bathroom plumbing should be properly and carefully done to prevent water damage.

Materials you will need DIY

If you’re doing this yourself, you will need to prepare all the materials beforehand and plan the basement bathroom carefully according to your present specifications while considering possible expansions in the future.

• Find the location of the drain that the contractors installed. This is a pipe that will be sticking out of the floor semi-above the concrete flooring. That is the drainage pipe and it would be easier to construct your shower there.
• Start to break out the area where you plan to install the basement bathroom plumbing system of your shower. The flooring is reinforced by mesh or rebar so you will have to remove that in order to have a space beneath the drain.
• The shower drain should open up to the outside vent stack. If this outside vent is impossible to access, use an auto-vent with rubber flapper for smooth draining of the trapped water.
• Frame the support structure according to the desired size of the bathroom. The water source should be installed in an interior wall so it will be easy to install an access panel in an adjoining room for future expansion.
• If you’re using fibreglass enclosure panels, secure these in place and then check your basement bathroom plumbing for possible leaks.
• Install the faucets and the shower-head. Place the shower curtain or a door for privacy.
