1. Measure the Area

Before you get started, it’s important to measure the area where your shower drain will be installed. This step is critical in ensuring that your new drainage system fits snugly into place and provides adequate coverage for your entire shower floor.

To begin, use a measuring tape or ruler to take precise measurements of the length and width of your shower area. Then, use these measurements to calculate the exact diameter of your shower drain by using the formula 2 x (length + width).

This will give you a good idea of where to start digging, as well as how large your drainage system needs to be in order to accommodate for any curves or changes in level. Keep in mind that the tiles must be put at least one and a half millimeters above the upper portion of the shower drain for the bath to drain completely.

For installing a new shower on your existing concrete floor, you need to first locate the flange. Hammer and chisel away at the cement surrounding it to reveal both bolts securing down this fixture as well as its attached flanges.

Fiberglass is an ideal material for such projects. Still, only if there’s already a drain roughed in with pipe surfaces visible above the ground – otherwise, further drilling into the concrete will be necessary!

2. Mounting the High-Quality Drain Assembly

 Once you’ve determined the exact dimensions of your shower area, it’s time to move onto the installation. To start off, firmly attach the central flush flange of your high-quality drain assembly to the concrete floor.

For a successful execution, use a level or other leveling instruments as needed in order to guarantee that your drainage system is evenly aligned with the flooring surface.

To make sure your shower drain is properly secure, run various tests with water or liquids to check for any openings and leaks. Once you’re confident the area’s fully sealed, it’s time to install the decorative top flange that comes with your kit.

Start by detaching the conventional grate from its spot, then attaching the new flange directly in its place. For enhanced protection against leakage, opt for a No-Caulk Shower Drain – an effective leakproof shower drain solution!

3. Linking the Drainage with Shower Pipes

Installing a drainage system to your shower is essential for safety and convenience! Start by connecting the high-quality drain assembly with a flexible hose, securing it in place through the paper gasket.

Secure the connection tightly with a locking clamp for an extra layer of security and assurance. After connecting your drainage system to the shower pipes, be sure to check for any potential leaks or defects.

4. Installing Tiles

Once your shower drain is set up, you should turn to tile the remaining area around it. As you tile, keep in mind that introducing a two-percent slope for the water drainage system is essential. Additionally, make sure to apply elastic coating so that the tiles don’t line precisely with sewage lines!

5. Sealing The Holes With Concrete

To finish the installation of your shower drain, seal all holes around it with concrete to create a waterproof barrier. This prevents any water or other liquids from leaking through and damaging your bathroom floor.

After allowing the concrete time to dry, remove any tape that you had previously used as a guide before enjoying your new bath space – make sure everything is totally dried out first!

How Much Does A Drainage System Cost?

Investing in a drainage system can be costly, but the overall expense may vary depending on the size and complexity of your project. Generally speaking, installing a basic draining system for an average-sized bathroom has an estimated cost between $500-$1800.

However, this price range could increase due to material selection and customization options that you select during construction. No matter what choices are made throughout the process though, it’s crucial to remember that using higher-quality materials will ensure reliable long-term performance from your drain installation!

Frequently Asked Questions

Can you put a drain on the existing concrete floor? 

Absolutely, it’s achievable to install a shower drain in an existing concrete floor – however, you must be mindful of any potential issues that exist beforehand. To ensure a successful drain installation, selecting the perfect system is key.

Once you know where it’s headed to be placed, begin by essentially setting up your drain and making sure that it’s leveled correctly. Lastly, lay down the final layer of concrete for optimal protection from water damage or erosion.

Where does the shower drain go on a concrete floor? 

Ensure that the shower drain is placed in an even spot on the concrete. Generally, a 2-inch drain with a P-trap located beneath the base must be installed for showers.

If you are looking to establish a fiberglass shower stall over an existing concrete floor, then it can effortlessly get done; however, if tiled showers need to be constructed, take precise measurements and try your best to restrict any movement occurring in the cemented area.

How much slope is needed to drain a concrete floor?

Achieving the right slope for proper drainage of a concrete floor depends on the size and shape of your shower area. The standard incline necessary is usually a one-quarter-inch drop per foot in length.

However, it’s important to account for any discrepancies if your floor isn’t level. When designing your shower, keep in mind that its main purpose should be for efficient water flow!

Does the floor drain need to be sloped?

For efficient, barrier-free water drainage, a shower drain must be accurately sloped with a drop of one-quarter inch per foot. This slope is essential for preventing dangerous pools of standing water and ensuring that the system operates smoothly.

Does a shower drain need a trap?

In accordance with the rules, all shower drains must have P-traps. This involves any pipes connected to a building’s major plumbing system. These traps are specially crafted tubes that fit underneath showers and other drainage systems, preventing noxious sewer gasses from infiltrating your home.

Without the use of this tool, water levels in piping would drop too low, and noxious fumes could infiltrate your residence’s plumbing network.


Finishing a shower drain installation may seem intimidating. However, with careful preparation and the right equipment, you can succeed in completing this project effortlessly. So don’t hesitate any longer!

Put your plans into action now, and experience the satisfaction of installing your own shower drain like an expert!
