What Are the Benefits of a Deeper Bathtub?

You can have a much more relaxing bathing experience if you install a deeper tub.

The bath may also help relieve tension by stretching the spine and muscles.

How Much Water Does a Bathtub Hold

A tub normally holds between 40 and 50 pints of water. The amount of water is enough to cover the entire body from the shoulders down to the feet. The water bathtub holds can be used to fine-tune your body and ease tension headaches or chronic stress and for therapeutic purposes following a muscle strain. Adding Epsom salts to the tub’s water can also help to soothe strained muscles.

Soaking Tub Depth

The depth of a soaking tub refers to how deep the water is in the tub. This can be important for those who want to soak in the tub to determine how comfortable the experience is. Generally, a deeper tub will be more comfortable as it will allow someone to submerge their body fully. However, if the tub is too deep, it can be not easy to get in and out of, which is why it is important to consider the depth when purchasing a soaking tub.

How Deep Is a Standard Bathtub

A standard tub depth is 15 to 38 inches or 38 cm. The depth of a standard tub is generally adequate to allow people to bathe without stooping over. However, torrentially deep tubs are readily available, particularly for those traveling because more space fosters maneuverability. The typical width of a standard tub is about 30 inches or 76 cm. This size works well for most people, but wider and narrower tubs are available if desired.

If your bathtub is not as deep as you would like, there is an easy solution that can make it deeper without replacing the entire tub. Also, you can do it by yourself. Before starting the project, all you need to do is add a waterproof liner to the bottom of your tub.

The liner creates a barrier between the water and the floor, preventing any damage from occurring. Additionally, a waterproof liner can help keep the tub clean by preventing soap and other debris from seeping through to the floor.

Cut and Fit a New Bottom to Your Tub

There are a few ways to cut and fit a new bottom to your tub, but the most popular way to cut and fit a new bottom to a bathtub is to use a template. To begin, you have to measure the length and width of your bathtub. Then, use a piece of wood or cardboard slightly longer and wider than those dimensions to cut off a template. Next, use the template to cover the bottom of your new bathroom and trace around it with a marker.

Seal the New Bottom to the Tub

To seal the new bottom to the tub, you have to fill a caulk gun with a silicone sealant. The nozzle of the caulking gun is then inserted into the crack between the tub and the new bottom, and the trigger is pulled until the sealant comes out of the nozzle. The sealant is then smoothed over the crack with a finger, ensuring no gaps or air bubbles.

Add Water to Test for Leaks

You would add water to test for leaks in your bathtub because if there is a leak, it will create a wet spot on the ground. If you add water to the area, you will be able to identify whether there’s a leak and what steps to take to fix it.

Add Caulk or Grout Around the Edge of the New Bottom

To add caulk or grout around the edge of the new bottom of your bathtub, first, make sure that the surface is clean and dry. If you are using caulk, cut the tube open and squeeze it out so that it is a thin line. If you are using grout, mix it according to the instructions and use a putty knife to spread it around the edge of the tub. Before using the tub, let it dry.
