    How to Prepare for Fitting a Bath

    To prepare for fitting a bath, you must begin by removing the old bath. The guide below provides a simple guide on how to remove a bath effectively. Some bath types may vary; however, this guide offers rough guidance on bath removals:

    1. Before removing the bath, it is vital that you turn off the water supply to prevent any leaking or damage.
    2. Once the water supply is switched off, you can then begin to remove the side panels of the bath.
    3. After the removal of the side panels, you need to turn both taps on and drain all of the water from the pipes.
    4. When the water has been drained, you can start dismantling the pipes from under the bath.
    5. The next step involves opening up the gap between the bath and the wall. You will need a craft knife to do this to cut through the sealant. You should also undo any fixings that connect the bath to the wall.
    6. Once all of the connections are removed from the bath, you should now be able to lift the bath out. It would help if you get a family member or a friend to assist you with the removal of the bath, as they can be quite heavy.
    7. You should then clean the area and make sure it is dry to prevent mould from growing.

    Before installing your new bath, you should carefully remove any covering or packaging, and then check the bath for any visible signs of damage before attempting to install it. You should also check to make sure you have all of the necessary parts, tools, and fittings that you need to complete the job.

    To create a watertight seal, you will then need to apply silicone sealant to the joint between the bath and the wall. It’s best to fill your bath with water first to ensure it doesn’t pull away from the wall when filled. Then protect your tiles with masking tape before applying the sealant.

    Use a sealant smoothing tool to smooth out the finish. Don’t empty the water from your bath until the sealant has dried. Once the sealant is thoroughly dried, your bath is now ready for use!
