A Guide to Buying Round Bathtubs!

2025-11-25

Round bathtubs are among the most popular types of bathtubs on the market, but we often don't know much about them when choosing one. Do you know which diameter is best for a round bathtub? How deep should a round bathtub be? How should we maintain a round bathtub?

1. Are round bathtubs a good choice?

The advantages of a round bathtub are its aesthetically pleasing shape and large interior space, accommodating two or more people simultaneously. However, the disadvantages are its larger size and the need for more installation space. Generally, a round bathtub is not suitable for small homes. Depending on the actual size of the bathroom, a round bathtub may be suitable for some larger homes.

2. Introduction to the materials used in round bathtubs

(1) Acrylic : Acrylic bathtubs are made of man-made organic materials and are characterized by their rich shapes, light weight, smooth surface, and low price. However, man-made organic materials have poor high-temperature resistance, poor pressure resistance, and poor wear resistance. They are also prone to aging, so the surface of acrylic bathtubs rarely changes color after three years of use. However, some brand manufacturers use imported high-gloss, high-hardness special acrylic sheets in their production of sanitary products, which overcomes some of the shortcomings of acrylic resin to a certain extent. If consumers believe that the bathtub will be used relatively infrequently, or if the house needs to be renovated within a few years, then acrylic bathtubs are more suitable for such consumers due to their good cost performance.

(2) Solid wood: Solid wood bathtubs typically use hardwoods such as spruce, oak, pine, and cedar, which are high-density and have good corrosion resistance. Cedar is the most common solid wood bathtub material on the market. According to a shopping guide for a certain brand of solid wood bathtubs from Daming Palace Building Materials Town, solid wood bathtubs not only give people a refreshing feeling, but also have the advantages of being easy to clean, static-free, and environmentally friendly. After bathing, they can be rinsed with clean water, and daily maintenance is even better. Simple solid wood bathtubs are prone to dampness and drying out. If necessary, soak them in clean water and avoid exposing them to sunlight.

3. Dimensions of a round bathtub

The size of a round bathtub varies depending on the specific circumstances. The actual radii of a round bathtub are 80cm, 75cm, 70cm, and 60cm. Among these, 70cm is more common in ordinary households. Round bathtubs are relatively large and have a unique shape. However, a round bathtub is not suitable for every family. First, it depends on whether the bathroom space is suitable. Because round bathtubs have size requirements, their diameter is relatively large, making them suitable for villas or large apartment spaces.

4. Diameter of a round bathtub

The diameter of a round bathtub is typically 1.5-2 meters, with common sizes being 1.8 meters and 1.5 meters. Custom sizes are available to meet specific family needs. When determining the size of a round bathtub, it is essential to consider the user's individual circumstances; a tub that is too large or too small will negatively impact comfort.

5. Tips for buying a round bathtub

(1) Check the gloss. Examining the surface gloss helps determine the quality of the material; this applies to any type of bathtub.

(2) Test the hardness with your hands and feet. The sturdiness of a bathtub is related to the quality and thickness of the material, which is not visible to the naked eye. Whether it sinks under gravity (e.g., standing) needs to be tested by yourself;

(3) Smoothness of the touch surface. This applies to both steel and cast iron bathtubs . Because both types of bathtubs require enamel plating, if the plating process is not done well, fine ripples will appear;

(4) Listen to the sound. When buying a high-end bathtub, it is best to "test the water" and listen to the sound. If the motor of the massage bathtub is too noisy, you will not be able to enjoy it and it will become a burden;

(5) Check after-sales service. In addition to checking product quality, brand and cost performance, after-sales service is also an important factor that consumers should consider, such as whether on-site measurement and installation services are provided.

6. Maintenance methods for round bathtubs

Round bathtubs are relatively cost-effective in the market, but they still require proper maintenance. After each use, round bathtubs need to be cleaned, dried, and kept moist to prevent prolonged exposure and extend their lifespan. Round bathtubs are not easily damaged by impacts and are prone to cracking or warping. Additionally, if the bathtub is made of wood, it is best to keep it moist for extended periods to prevent deformation due to moisture.
