When installing a new shower, you will need to install a backer board over the shower pan lip. This will help to prevent water damage and mold growth.
The answer is no, backer board should not go over the shower pan lip. The lip is there to keep water from going under the pan and into the subfloor, so covering it with backer board would defeat that purpose.

Should backer board go over tub lip?
When installing cement board or other tile backer around a tub, the best approach is to keep the cement board out of the lip area. Apply it to the wall with the bottom edge about 1/4 in above the lip of the tub. This will help to prevent water damage and ensure a long-lasting tile installation.
The lip of the shower pan provides a great starting point for installing wallboard. The bottom edge of the board can be easily aligned with the shower pan and leveled. This will ensure that the board does not touch the pan and is level.
How close should cement board be to shower pan
It is important to provide a 1/4 in clearance gap between the floor, tub or shower receptor base and the cement board. This is to allow for expansion and contraction of the cement board. Do not place cement board into the shower pan mortar bed as this can cause cracking.
It is important to install a moisture-resistant backing material, such as cement board, behind tile or panel assemblies in tub and shower enclosures. This will help to prevent water damage and mold growth. Do not use paper-faced backer board, as it is not resistant to moisture.
Does cement board go over tub flange?
When setting a tub during a drywall installation, it is important to set the tub prior to the drywall. The cement board should then be installed and stopped at the top of the tub flange. The tile should be installed on the cement board and span over the flange, sealing to the tub top surface with grout and caulking.

Can I tile directly on cement board in shower?
Cement board is an ideal material for tile installation because it is durable, stable, and does not contain any organic materials that could be susceptible to mold or rot. Ceramic tile laid over cement board is one of the most durable floor or wall surfaces you can install.
You will also want to make sure that you purchase enough backer board to cover the wall all the way up to 6 inches (15 cm) more than the height of the tub. This will ensure that the wall is properly protected from water damage.
What do you put behind cement board in shower
Cement board and a sheet membrane is a popular application in which a cement board is installed directly on the studs with no plastic sheeting behind it. Waterproof sheet membrane, also called uncoupling membrane, is applied to the cement board with thinset adhesive. One such brand of sheet membrane is Schluter Kerdi.
It is important to leave a small gap between the cement board and the tub flange in order to ensure a proper seal. Sealant should be applied to the gap to prevent water from leaking through. Stopping the cement board above the tub flange or dropping it down near the tub are both good options.
What’s the reason of installing a backer board at the bottom of the wall?
Backer board is a type of material that is used to prevent water damage. It is especially useful for installations where there is a risk of exposure to water. Backer board is made of cement, which is a durable material that will not rot, warp, or grow mold and mildew when exposed to water. This makes it an ideal choice for permanent installations.
Drywall always goes on top of the shower pan, after the pan is set into the floor. This is true regardless of whether you choose to install tile or panel walls. Panels can be installed directly on top of the shower pan, but tile needs a layer of drywall to provide a sturdy surface for the adhesive to adhere to.
