臺灣2022前十年整體衛浴產業供需調查分析

Taiwan 2022 Decadal Supply and Demand Analysis of the Unit Bathroom Industry

本研究以深度訪談來瞭解整體衛浴產業供需狀況，調査期間為2022年。建築物生命週期依序為設計、施工、使用、整建、拆除。設計時期所因應訪談對象為建築師和廠商，施工為營造廠與廠商，使用為業主，拆除與整建則為營造廠與廠商。綜觀生命週期的各個時期主要訪談對象，以「廠商」訪談最為關鍵，因此深度訪談對象以廠商為主，具備整體衛浴設計與施工的建築師、營造廠為輔。

This study used in-depth interviews to understand the supply and demand status of the unit bathroom industry, with the survey period set in 2022. The primary interviewees were manufacturers, supplemented by architects and construction companies with experience in the design and construction of unit bathroom systems. According to the Taiwan Cultural Sanitary Ware Association, the total production capacity of unit bathrooms over the past decade, as of 2021, was 14,983 sets. Among them, residential buildings accounted for 4,116 sets (27.47%), dormitories 2,628 sets (17.54%), and public housing 1,238 sets (8.26%). These three residential types together made up 53.27% of the total. The proportions of public works projects versus non-public works projects were 44.81% and 55.19%, respectively, while the ratio of new construction to renovation projects was 88.83% to 11.17%.
Based on the interview findings, the sales volume in 2021 was approximately 5,000 units, with annual revenue reaching around NT$600 million. The estimated production volume is projected to reach about 10,000 units by 2025 and 30,000 units by 2030. The product sources for unit bathroom ware manufacturers can be categorized into three types: A. Entirely self-produced and self-sold; B. Partly imported, combined with self-production and self-sales; C. Entirely imported.
In recent years, due to rising construction costs and labor shortages, manufacturers of unit bathroom ware generally maintain an optimistic outlook on the growing sales of unit bathroom products that enable rapid construction. From 2023 to 2028, the National Housing and Urban Regeneration Center plans to build a total of 64,573 social housing units across Taiwan. If regulations require 20% of these units—about 13,000 housing units—to adopt a unit bathroom, and assuming an average of 1.3 sets per housing unit, this would generate an additional demand of 16,900 sets. This policy would also contribute to the development of Taiwan's construction and sanitary ware industries. The study's projected annual production capacity for the unit bathroom market over the next decade is sufficient to meet the additional demand arising from 20% adoption in social housing projects between 2023 and 2028.
