As two mainstream types of sanitary ware in modern bathrooms, wall hung toilets and floor-mounted (normal) toilets differ essentially in their installation structures. This fundamental distinction further drives variations in space utilization, daily usability, long-term maintenance, and cost investment—factors that directly determine their adaptability to different bathroom layouts, user needs, and decoration budgets.
The installation method and structural design are the root causes of all other differences between the two types of toilets, and they also impose different requirements on the bathroom’s basic conditions.
Wall hung toilet: It relies on a pre-embedded load-bearing steel frame or a wall-mounted bracket for fixation. Its water tank and water supply/drainage pipes are concealed inside the wall (either integrated into the load-bearing wall or hidden behind a custom false wall), with only the toilet bowl suspended 15-20cm above the floor.
Floor-mounted toilet: It adopts a “direct floor contact” design. The base of the toilet is firmly fixed to the bathroom floor using expansion screws, and its water tank (either one-piece with the bowl or split-type) and related pipes are fully exposed, forming a complete visible structure.
Wall hung toilet: It is highly dependent on the construction phase. It must be installed during bathroom renovation (to embed the steel frame and arrange concealed pipes); post-renovation retrofitting requires demolishing walls or building false walls, which is costly and time-consuming. Additionally, it requires the wall to have sufficient load-bearing capacity (or a professional load-bearing frame) to support ≥300kg of weight.
Floor-mounted toilet: It has low installation thresholds. It can be installed both during renovation and when replacing old toilets—provided the position of the floor drain pipe matches. It has no special requirements for wall load-bearing, as its weight is fully distributed to the floor.
For users, the daily experience (including space perception, cleaning convenience, and usage comfort) is a key factor in selection, and the two types of toilets show significant gaps in this regard.
Wall hung toilet: The suspended design eliminates floor contact, freeing up the space under the bowl. This not only reduces actual floor occupancy but also creates a “visual lightness”—making small bathrooms (≤5㎡) appear more open and in line with minimalist or high-end decoration styles.
Floor-mounted toilet: Its base occupies 0.2-0.3㎡ of floor space, and it requires at least 50cm of empty space around it to avoid collision. In narrow bathrooms, it is prone to creating a cramped visual effect and limiting movement.
Wall hung toilet: The exposed floor under the bowl has no dead corners (such as gaps between the base and the floor), allowing users to clean the floor and toilet surface with a single wipe. Additionally, the bowl height can be adjusted (40-45cm) during installation, adapting to children, the elderly, or users of special heights.
Floor-mounted toilet: The gap between the base and the floor easily accumulates dirt, hair, and water stains, requiring small brushes for deep cleaning. Its height is fixed (35-42cm), which may cause discomfort for users who are too tall or too short. Moreover, its exposed water tank produces obvious flushing noise, which can disturb rest in bathrooms adjacent to bedrooms.
Beyond initial purchase and installation, long-term maintenance costs and operational flexibility are also important for users to evaluate the “cost-effectiveness” of the toilet.
Wall hung toilet: The total cost is significantly higher. The toilet itself is 1.5-2 times the price of a mid-range floor-mounted toilet; plus the cost of the concealed steel frame (usually $100-$200) and false wall construction (if needed), the total investment is 2-3 times that of a floor-mounted toilet.
Floor-mounted toilet: It has high cost-effectiveness. Mid-range models cost only $100-$300, and installation only involves fixing the base and connecting pipes—with a one-time installation fee of less than $50, resulting in a much lower overall cost.
Wall hung toilet: Maintenance is complex and costly. If the concealed water tank or pipes fail (e.g., water leakage, valve damage), the wall or false wall must be disassembled for repairs, which may damage the bathroom’s decoration and incur high maintenance fees.
Floor-mounted toilet: Maintenance is simple and low-cost. All components (water tank, flush valve, pipes) are exposed; faults can be identified and repaired directly, and parts can be replaced quickly—with no need to damage the existing decoration, ensuring high maintenance flexibility.

When choosing, users should comprehensively consider factors such as bathroom area, decoration style, budget, and family population (e.g., whether there are elderly or children). For small bathrooms or those pursuing a high-end minimalist style, wall hung toilets are a better choice; for those focusing on cost-effectiveness and convenient maintenance, normal toilets are more suitable.
