How to Manage Water Drainage in a Bathroom Without a Floor Drain

Because kitchens and bathrooms are both areas that deal with water, floor drains are very important. If there is no floor drain installed, a leak could lead to flooding. So, what can you do if your bathroom doesn’t have a floor drain?

How to Remedy a Bathroom Without a Floor Drain

First, check the location of the drainage pipes downstairs to confirm their position. Then, you can pry up the floor tiles to find the drainage pipe, and reinstall the floor drain. Make sure to find a good slope for the water flow, ensuring that every inch has proper drainage. Next, measure the dimensions accurately, cut the gap, and install the floor drain. This will complete the process.

How to Install a Floor Drain

1. Prepare the Floor Drain According to the Diameter of the Drainage Pipe

The first step is to purchase the floor drain, and it’s essential to avoid making a blind purchase to prevent mistakes that can lead to difficulties in replacement. We should know the diameter of the drainage pipe for the floor drain beforehand. Typically, it is a 50 mm PVC pipe, and if it’s cast iron, it should be slightly larger. The diameter of the drainage pipe should match that of the PVC pipe. When the house is handed over, the reserved drainage hole may be larger, so adjustments will be made during renovation. Therefore, the drainage pipe should be fabricated according to the size of the floor drain, and it is not recommended to trim the drainage pipe before purchasing the floor drain.

2. Determine the Installation Location of the Floor Drain

Before installation, we need to determine the direction to place the floor drain so that a slope can be created during tiling. The floor drain should be at the edge of the tiles; if it’s in the center, it will not facilitate drainage. It’s crucial to test the drainage effect in advance to avoid future pooling issues.

3. Connecting the Floor Drain to the Drainage Outlet

Typically, a small pipe will be provided to connect to the drainage pipe. Place the drain core at the outlet of the drainage pipe and apply a layer of cement to ensure it stays in place. If the floor drain wobbles or has gaps, it is prone to leaking, so special attention should be given to the connection and sealing between the floor drain and the drainage pipe. You can use professional adhesives or silicone sealant for sealing.
