Due to their frequent use, the bathtubs are subject to fairly strong wear and tear. It is normal for a bathtub to become dilapidated, scratched, worn or stained over time, so you have to change them periodically. The thought of replacing your bathtub can seem daunting, as it requires plumbing, carpentry, and even tiling work. But if you plan everything correctly in advance and prepare to spend a certain amount of time and effort on such work, then you can replace the bathroom yourself. And our article should help you figure it out.
Step 1. Plan all the details of the work
- Measure your current bath. The correct dimensions will help you get the correct sized bathtub and fixtures, and also make sure your old bathtub will walk past your existing fixtures and through the door when removed. You may need to temporarily remove the washbasin, toilet, or bathroom door to take out your old bathtub.
- Purchase new ones and remove any damaged tiles, or install a solid protection around the bathroom.
- Cover your bathroom floor with a soft or plastic backing for protection.
Step 2. Dismantle the installed bath
- Unscrew and remove the overflow protection cover including all associated drains.
- Using a screwdriver and a special wrench, disconnect the drain device, filter and flange.
- Disconnect the drain elbow from the drain line. You can get to the drain elbow under the bathtub or through a special removable panel.
- Disassemble the surrounding wall surface 20 cm above the bathtub. You will also need to remove the drain pipes and valve valves within a radius of 20 cm. Remove the tiles with a spatula, cut off the gypsum-cement slab or drywall with a special saw.
- Remove the anchor screws or nails that secure the tub rim to the wall.
- Cut off the sealant with a mounting knife, and using a pry bar, slightly pry the tub from the back wall.
- Using a pry bar, first lift one and then the other edge of the bathroom. Ask a friend to help you lift the tub upright and out of the bathroom.
Step 3. Prepare a place for a new bath
- Replace damaged plywood or flooring.
- In order to properly fix the longitudinal elements at the desired height to the wall uprights, the instructions of the bathroom manufacturer must be followed.
- Check that the new drain and drain elbow are the right size.
Step 4. With the tub on its side, dry connect the overflow tube and support shoe
Check the correct position and then firmly connect the assembly according to the manufacturer's instructions.
Step 5. Assemble the entire drain assembly and install it securely in the new tub according to the manufacturer's instructions
Step 6. Place the bathtub in the desired position and, together with an assistant, set it in place by tilting, lifting and moving
Take care not to damage the protruding waste unit and the inner surface of the bathroom.
Step 7. Align and secure the tub to the wall according to the manufacturer's instructions
Step 8. Connect the drain line and check for leaks by running water into the tub, removing the plug, and making sure the drain line remains dry
Close the access panel.
Step 9. Seal the joints with the floor with a thick bead of silicone or tile sealant
Water will enter all the gaps between the two surfaces, and if it seeps under the bathtub, it will damage the floor underneath.
Step 10. If necessary, install a new mixer
Step 11. Restore the surface of the wall by securing a special edge or laying tiles
Seal the joints with the walls with a thick bead of silicone or tile sealant.
- Fill in the missing wall surfaces by installing a cement backing sheet that is more moisture resistant than conventional drywall.
- For proper draining, the tub must be horizontal.
