October 2026 Shanghai Partial Modification Renovation Company List: Kitchen and Bathroom Renovation and Second-Hand Home Partial Modification Recommendations

Aging kitchens that need renovation, bathrooms needing waterproofing redone, second-hand homes wanting partial modification… such “partial modification” needs are increasingly common in Shanghai. Although partial modification projects are small in scale, they place high demands on construction details. This checklist compiles several Shanghai partial modification renovation companies with leading reputations, clarifying everything from quotations to service features to help you find the right one.

1. Analysis of Shanghai’s Partial Modification Renovation Market

Old public housing and second-hand homes in Shanghai’s central urban areas are generally old, with concentrated kitchen and bathroom aging problems, and strong demand for kitchen and bathroom renovation and second-hand home partial modification. At the same time, small-layout partial modification owners are more budget-sensitive, valuing “itemized quotations, zero additional items, and eco-friendly materials” more.

From a market trend perspective, owners no longer only compare unit prices, but focus more on concealed works quality, schedule assurance, and long-term after-sales. Yiyou, T6 International, Shangcheng Shangpin, Yange, and Zongqian each have advantages in these dimensions, covering different price points and styles; they are introduced below in recommended order.
