If you opt to do it yourself, installing a new bathtub is a task that demands a great deal of care and precision. After carefully selecting the tub that best suits our needs and the best location in the bathroom for its installation, it will require removing the old tub and replace it, ensuring that all of the tub’s functional elements are connected in the best possible way.

A new sink can be fitted quickly, but a new bathtub requires more expertise and special tools. Above importantly, even minor errors can swiftly result in expensive flooding. Bathtubs can be mounted on a support frame or placed in a firm foam bathtub support.

Steps To Install The Bathtub

If you want to install the new bathtub on the concrete floor, you have to follow the discussed-below steps:

1) Remove The Old Bathtub

The old bathtub must be disassembled before installing the new one. To minimize flooding, the water supply must first be shut off, and a big basin has to be set up to catch any residual water in the pipes that may leak during the activities.

The old adduction pipes, overflow pipes, and drain will need to cut using a metal-cutting saw to remove the old tank. You can also remove the tank after being crushed with a club, depending on the material from which it is made.

2) Choose The Bathtub According To Floor

There are many different bathtubs; before purchasing one, it’s crucial to know which sort of tank will fit into the given area. If you want to secure your bathtub, you’ll need bathtub feet that match it. They’re pretty general, but the devil is often in the details.

Bathtub rails must also be installed on the wall to support the bathtub’s edge. Bathtub anchors are sometimes sold as part of a set with bathtub feet, although they can also be purchased independently.

3) Fix The Feet Rails

Fastening rails and adjustable feet are standard features of bathtub feet. You have to fasten the rails to the bathtub’s underside. This method works with both steel and acrylic tubs.

To avoid harming the tub, make sure you use the correct screws. It’s up to you where you attach the feet to the underside. Ensure, however, that the tub feet do not obstruct the wall connection or the drain installation later on.

4) Use screws On The Rails

Attach two feet to each rail now. Do not, however, tighten the tub feet just yet. After turning the tub over, you must first align it horizontally. Unevenness can readily level, thanks to the adjustable feet. So, grab the spirit level and adjust the bathtub to a horizontal position. The screws on the feet can now be tightened.

5) Install The Drainage System

Assemble the overflow and drain fittings at this point. They are sometimes included in the bathtub purchase. However, they must be ordered separately for other bathtubs. Deal with the overflow first: Install the overflow body and profile gasket. The mounting flange can tight into the overflow body. On the overflow body, place the rotary knob.

Now for the drain, place the sealing ring with the screw-in valve into the drain hole. Place the appropriate seal on the siphon and direct it to the drain hole from below. Connect the siphon and the screw-in valve.

6) Anchor The Bathtub On The Wall

Bathtub strips can anchor the bathtub to the wall so that it stands securely in the future. On both the long and short sides of the coin. For both acrylic and steel tubs, tub strips and tub anchors are essential.

Furthermore, sound insulation frequently includes in the strips. As a result, sound transmission between the tub body and the wall is reduced.

Lift the bathtub to the side and make a mark on the lowest border of the bathtub. Using a spirit level, extend the wall markings. Both parties are in agreement. Make sure the top side of the strips touches the marking line. Now, you can easily mark the drill holes.

7) Use Silicone sealant

Finally, use silicone to seal the gaps between the bathtub and the wall. However, this does not constitute a complete seal. Silicone can become brittle over time, allowing moisture to penetrate the wall. As a result, a tub sealing tape seal requires in all cases.

Tub sealing sets include tub sealing tape and tub sealing corners. To begin, adhere the sealing corner to the bathtub with a glue gun. And in such a way that it is flush with the bathtub’s lower border.

If the sealing corner fits, the sealing tapes overlap and are connected to it. Cut the tape to match the length and width of the tub, then glue it to the tub’s edge, flush with the bottom.

8) You Are All Set To Place The Bathtub!

Now it’s time to put the bathtub in its ultimate location. Screw the bathtub rails into the bathtub and tighten them. It’s now more critical than ever to connect the drain and overflow fittings to the wall connection. Align the drain connection piece on the drain fitting for this reason so that it can be connected to the drain as quickly as possible.

HT pipes are commonly used for the connection, which can simply short using a metal saw. To avoid tiny leaks later, the cut edges must be deburred.

A two percent gradient between the drain fitting and the wall connection is essential to reliably ensure that the bathwater drains. You need to underlay the pipes. So, they don’t sag. For example, small wooden panels or stiff foam residues. That’s All from our side. Now, it’s your turn to install the bathtub on the concrete floor in your bathroom.
