The stock renovation market has exploded, and stepped sinks have become the core incremental category of home decoration channels

According to data from domestic kitchen, bathroom, and home decoration channels in the first half of 2026, the growth rate of demand for high-end matching sinks in new homes fell by 3.7% year-on-year, while orders for partial renovations and kitchen renovations in old homes increased by 27.4% year-on-year. Ladder style single sinks and double sinks have become the core products driving market growth due to their spatial optimization properties, completely changing the traditional pattern of a single and double sink market in the past. After visiting more than 30 home decoration stores in cities across the country, industry research institutions found that 72% of renovation owners actively choose a stepped structure style when replacing sinks, with core demands focused on improving the utilization of kitchen space in small-sized units and operating meal preparation and washing zones. The traditional flat sink can only complete the single action of water storage and cleaning, while the stepped sink relies on the high and low layered countertops inside the sink, which can directly place drainage baskets and vegetable cutting boards without occupying additional kitchen countertops, making it highly adaptable to current mainstream compact kitchens under 6 square meters.
From the perspective of product iteration, in the early days, the stepped sink was simply divided into high and low layers, and the process was rough and prone to dirt accumulation; After nearly two years of process optimization, all mainstream products in the industry now use integrated stretching forming technology, without welding seams, and the circular arc transition surface synchronously solves the problem of cleaning dead corners, which is also known as the arc-shaped stepped sink in the market. According to feedback from the channel, the unit price of the stepped sink is 20% -40% higher than that of the ordinary single sink, and the profit margin is significantly better than that of the basic model. Therefore, both the whole decoration company and offline building materials stores have made it their main product for promoting and attracting traffic. The online content platform data synchronously confirmed this trend. The broadcast volume of Tiktok and Xiaohongshu platforms' "ladder sink transformation" related content exceeded 1.2 billion times in half a year. A large number of home decoration designers launched standardized transformation plans to further educate consumers.
However, the industry also faces the hidden danger of homogeneous competition. A large number of small and medium-sized manufacturers have followed the trend by replicating stepped structures, simplifying supporting processes such as noise reduction, anti condensation, and nano anti fouling coatings. Low priced and inferior products have flooded into the sinking market, resulting in a year-on-year increase of 16.2% in terminal after-sales complaints. Industry experts say that in order to achieve long-term healthy development of the ladder sink track, the manufacturing side needs to establish a unified process standard, distinguish between integrated stretching and splicing imitation products, and at the same time, link with home decoration channels to carry out science popularization, guide consumers to pay attention to core quality indicators such as board thickness, drainage system, and surface treatment, and avoid using low price appearance as the sole purchasing criterion. In the medium to long term, with the continuous implementation of the national policy for the renovation of old urban communities, the segmented track of tiered water tanks will continue to maintain double-digit growth rates, and is expected to occupy more than 35% of the household water tank market share within three years.
