Bath tubs may settle, similar to how a home can settle. The settling can cause unevenness as time passes. If a bathtub is not level, it will not drain properly, and plumbing fixtures could get loose and cause leaks. The bath tub eventually must be leveled to get the same level as it is. There are two ways to do this depending on the type of footed bathtub or a solid base.
Step 1
Lay the board , keeping the longer side horizontal along the entire length of your tub. Place the carpenter’s level onto the board in the middle. Check the bubble on the level. In the event that the tub is located between two lines, the tub has been level. In the event that the bubble has been placed closer to one side when the line is passing over the top of the tub, that will be the part of the tub that needs to be raised. Take note of what side of the tub it is located on and the amount of bubble is passing through the line. The more of the bubble passes the line and the less uneven the tub appears to be.
Step 2
Collect readings from various places within the tub to get an accurate view of the unevenness of the tub. Utilize the four corners side, sides, the front and back for these measurements. If the sides that are more elevated than the other sides, you can use to measure the depth of the tub to get measurements.
Step 3
Utilize the readings to determine the exact location at which the tub needs to be elevated.
Footed Tub
Step 1
Place the level in the area in the tub that is uneven.
Step 2
Let someone lift the tub in the corner that must be lifted.
Step 3
Place wood shims on at the bottom of the bathtub. Continue to build support under to ensure that the bathtub is level in accordance with the reading of an indicator bubble that is on the carpenter’s scale. Repeat this process if a different corner needs to be raised in order to finish the leveling.
Unfooted Tub
Step 1
Purchase premixed mortars in the amount that will make the floor level beneath the tub. The mortar must be sturdy enough to allow the tub to be placed in its place and then to hold it.
Step 2
Apply the mortar following the instructions of the manufacturer to prevent cracks or damage to the floor underneath it. Let the mortar have a short time to settle but not enough time to set permanently. The mortar must be flexible enough that it will allow some flexibility to the tub once the tub is placed upon it.
Step 3
The bath tub should be placed in a place so that the upper side of the tub sinks in the mortar. Adjust the level of both sides to ensure that it is level. If necessary, adjust the level rapidly, but cautiously.
Step 4
Let the tub rest on the mortar for long enough to allow the mortar to be set for a long time.
