12 Tips on Bathtub Installation


by DoItYourself Staff

Bathtub installation can prove to be a difficult job to perform. Therefore, before installing the bath tub, be sure that you have considered  other options such as the addition of a new bath tub liner. This option will help in utilizing the existing walls and plumbing, without physically removing the old bathtub. Nevertheless, if you have already detached the old bathtub and want to install the new one, this article will help in giving you some common tips that must be remembered when installing the bathtub.

Tip 1: Check the Flooring

Make sure to examine the flooring to find out if there are any damaged floorboards. If it is damaged, then you need to replace these floorboards before moving on to the next step.

Tip 2: Check the Piping

The piping needs to be installed in the right way before installing the new bath tub into place.

Tip 3: Assembling Drain Connections

Turn on the water to check if there is any leakage and repair the areas from where there is leakage of water.

Tip 4: Sealing the Area

You can seal the area around the tub with silicone to prevent water from dribbling behind the fixtures and causing water damage.

Tip 5: Installation of Bathtub

You need to make sure that the bath tub is resting on the floor and not the bath tub rim.

Tip 6: Supporting the Frame

The size of the frame generally depends on the size of your bath tub. The supporting frame is mainly constructed of wood and the bath tub is placed inside this supporting frame when it is completed.

Tip 7: Nailing the Bathtub

You then need to fasten the bath tub in the right position with the help of galvanized nails through flanges.

Tip 8: Sliding the Bathtub

Slide the bath tub into the right place and with the help of plastic shims, level this bath tub. After the bath tub is leveled to its right position, just mark the top of the tubs nailing flange on the studs.

Tip 9: Position of Ledger Boards

Settle the position of the ledger boards as these boards will directly help in attaching it directly to the wall studs underneath the bath tub to support it.

Tip 10: Measuring the Length

Gather the drainage pipe and fit them into the bath tub, so you can measure the required length to attach the drainage pipe to the bath tub.

Tip 11: Ledger Boards

You can install the ledger boards on the determined markings and utilize the galvanized nails to prevent any rusting on the bath tub.

Tip 12: Mortar Bed

With the help of a thinset motor, say about an inch or two of thickness, chip the old motor away and make a new one. The thickness of this mortar bed can be extremely important because this will be supporting the bath tub when it is at its heaviest and filled with water.

Last but not the least, turn on the water again and test your drainage systems once again for any leakage and finish the walls, installing the shower head as well.
