Bathtub Sizes for Mobile Toilet Renovation

When renovating a mobile toilet, the bathtub size should be selected based on the type and the area of the bathroom. Here are the common sizes and suitable scenarios:

I. Selecting Sizes by Bathtub Type

1. Ordinary rectangular movable bathtub: Length ranges from 1200mm to 1900mm, with 1700mm being the optimal size. Width ranges from 700mm to 900mm (narrow sides save space, while wide sides offer more room for stretching). Height ranges from 355mm to 518mm (low sides facilitate easy entry and exit, while deep tubs provide a stronger sense of immersion). This type of bathtub fits most household bathroom layouts and is a popular choice.
2. Sit-in movable bathtub: Fixed size of 1100×700×475mm, with a sitting height of only 310mm. It is easy to get up from and features a non-slip design for added safety, suitable for small apartments or the elderly.
3. Massage movable bathtub: The single-person model has dimensions of 1500×(800 - 900)×470mm; the double-person model measures 1800×1500×700mm, requiring more space to accommodate the hydraulic system. The double-person model can hold 300 - 500 liters of water, suitable for users seeking functionality and comfort.
4. Folding movable bathtub: When folded, it is only 10cm thick. The expanded size varies by brand (e.g., the expanded size of the Benmai brand is not specified). It is made of food-grade TPU material and does not crack at -30℃, suitable for renters or temporary use scenarios.
5. Round movable bathtub: With a diameter ranging from 1.5m to 1.8m, it exudes a sense of luxury but takes up a lot of space, commonly found in villas or large-apartment bathrooms.
6. Sector-shaped movable bathtub: With a diameter ranging from 1.2m to 1.7m, it can be installed in a corner to save space, suitable for bathrooms smaller than 5㎡.
7. Triangular massage movable bathtub: The beveled design fits snugly into corners, maximizing space utilization, suitable for small apartments or irregularly shaped bathrooms.
8. Double-person movable bathtub: Standard sizes include 1860×1400×780mm, 1800×1200×740mm, etc. Custom sizes can be extended to a length of 2000mm and a width of 1800mm. When installing, leave at least 150mm of clearance space, ensuring comfort during use.

II. Selecting Sizes by Bathroom Area

1. Bathrooms ≤4㎡: Prioritize sit-in bathtubs (1100mm) or sector-shaped bathtubs, saving space while meeting basic needs.
2. Bathrooms 4 - 6㎡: Standard rectangular tubs (1500 - 1700mm) are the best choice, balancing functionality and space utilization.
3. Bathrooms ≥6㎡: Double-person bathtubs (1800mm) or round massage tubs can be installed, enhancing luxury and user experience.

III. Key Considerations

1. For massage bathtubs, reserve space for water and electricity lines and drainage outlets, ensuring normal functionality.
2. For folding bathtubs, confirm that the expanded size matches the bathroom to avoid installation issues.
3. For custom bathtubs, communicate dimensions and installation requirements with the manufacturer in advance, preventing rework later.
