Concrete is great for its strength and resilience, so you can expect your tub to last you many years without needing any repairs or replacements.

2. Customizable

You can even choose the type of additives that go into the concrete to make it especially suited for use in bathrooms with high humidity or high traffic areas. 

3. Value

Another benefit of a concrete bathtub is its value. While these tubs are by no means inexpensive, they do offer good value over time due to their long life span and high durability. This can be an attractive option for homeowners who are planning to remain in their homes for many years to come.

Concrete is extremely heavy, making it difficult to move around once it has been cast. You will need a strong subfloor that can support the weight of the material.

Concrete is a heavy material and consequently, so are concrete bathtubs.

This can be problematic if you live in an older home or apartment that wasn’t built to withstand the weight of a concrete bathtub.

If you are considering having a concrete tub installed, make sure to speak with a contractor about reinforcing the space around it.

2. Hardness

Although concrete can produce a smooth surface, it is fairly hard. Which means that it isn’t as comfortable or warm against the skin as some other materials, such as acrylic or cast iron.

This hardness also makes concrete more susceptible to chips and cracks than other materials.

3. Cost

Concrete is an expensive material, which means that concrete bathtubs are often expensive as well. There is no way to get around this fact.

If you want a custom tub made of concrete, expect to pay top dollar for it. You will also have to pay more for shipping and installation because the tub will be heavy and difficult to maneuver.

4. Maintenance

Unlike many other materials, concrete needs special care when it comes to cleaning and sealing. This is especially true when it comes to the grout used between your tiles and the surface of your tub.

Consult a professional before attempting any maintenance on your concrete bathtub, even something as simple as washing it.

What is a Concrete Bathtub Mold?

A concrete bathtub mold is simply a mold made out of a strong, durable material that can withstand water and heat without deforming or warping.

There are various types of molds available for concrete casting: some made of plastic or metal; others made of rubber or silicone; even others made of wood or clay.

Cost of Construction vs. Concrete Bathtub for Sale -Which is Better? 

The cost of construction can be high. Even though you may have the funds to cover it, the cost is still steep. In addition, there are other aspects such as the availability of materials and so on. A concrete tub can be a good option in this case.

The cost of these portable concrete tubs is much less than those that are cast at a factory because the material used in the manufacturing process is cheaper.

Another advantage of portable tubs is that they are portable. They also take up less space than those installed at a factory site. This makes them ideal for people who want to use their bathroom but do not want to spend too much money on it.

However, there are many portable concrete tubs on the market designed for building at home and transported to a site where they can be set up. These units come with pre-cast concrete panels or pre-cast steel frames.

The pre-cast panels come in different designs and sizes depending on the type of tub under use. The pre-cast steel frame is made from high-strength steel alloy and welded together into a frame.

Common Concrete Bathtub Ideas

Here are some common concrete bathtub ideas:

  1. Long and Narrow – For bathrooms with limited space, a long and narrow tub is a great option. Keep in mind that you should have about 2-3 feet of clearance on either side of the tub for ease of cleaning and access.
  2. Corner Tub – A corner tub will save space and make the bathroom feel more open at the same time. The shape itself adds an interesting design component to your bathroom as well. If you want to create this look yourself, use a jigsaw to cut out the ends of your mold where they will meet up with the wall to create a 90-degree angle.
  3. Bathtub/Shower Combo – You can make a tub that doubles as a shower if you want to save space or don’t have room for both. Use two drains, one on each end, so that you can use it as either a tub or shower.
