Tip & How-To about Plumbing
Anyone can install a water bathtub, but to do it right so that it will last a lifetime takes some time to make sure that it is installed properly. If installed correctly the bathtub you install will be well supported and will not experience the stress that ones that are not installed properly will experience.
The first part is to make sure that the space is exactly the same size as the tub or tub/shower unit. Leave the end wall out till the unit is in place and then fasten it in place.
If you take the time to notch out for the lip on the tub or the tub/shower unit, your dry wall will not have to bow out over it. Place the unit in place and mark the studs, then chisel out ¼” deep so that the tub sits back and the lip is flush with the face of the studs.
Once you have the unit “fitted” exactly to the space, you are then ready to install the bathtub or tub/shower unit. By this I mean that I “set” the unit in a bed of mortar to make sure that the bottom of the unit and the unit it’s self cannot possible move or flex when weight is in it. To do this you need to make a bed to set the tub into.
Depending on the size of the unit, usually one bag of mortar mix will be sufficient for one fixture. Mix the water with the mix right before you are ready to set the unit. Make sure that the mix is stiff enough so that when you place it on a pile it will stay and not run. Now place the mortar in the center under where the unit will set. Place a sufficient amount so that you will have to press down on the unit to “set” it into the mortar.
Carefully place the unit in place and gently press it into the mortar until it is sitting level. You can now place a couple of screws into the lip to hold it in place until the mortar gets hard. After a few hours the mortar will be hard and will fully support your unit. The bottom of the unit will not be able to flex at all and your unit will be on the road to outlasting you!
You can now finish the remaining wall, then trim the unit and finish the walls. Plumbing can now be installed. Remember to provide access to the plumbing just in case of future problems.
