FAQ

What is the lip of a bathtub?

The rim of your bathtub is the upper edge or lip that serves as a stable base for the tub and prevents water from overflowing. It not only supports the tub but also acts as a barrier to catch any water that may spill out when the tub is filled to the top.

What is bathtub flange?

A bathtub drain flange is the visible part of the drain in the tub, also known as a “drain body” or “drain basket” by some manufacturers. It is available in various finishes and offers a range of stopper options to help fill the tub.

What is a tile lip for a bathtub?

The tile flange is a useful feature that allows you to extend the wall tiles downwards over the flange. By doing so, it effectively prevents water spray from the shower and splashes from the bath from seeping in between the bath and the tiles. This not only helps maintain the overall aesthetics of your bathroom, but also serves as a protective barrier against potential water damage to the wall and floor in the tub deck area. Installing a bath with a tile flange ensures long-term durability and minimizes the risk of any costly repairs in the future.

Should cement board overlap the tub?

To ensure that the tiles have a secure surface to adhere to, it is important for the backer board to extend beyond the tub flange. This can be achieved by placing shims between the backer board and the studs, ensuring that the wall is perfectly vertical. Additionally, it is recommended to leave a 1/4″ space between the tub ledge and the backer board for proper installation.
